4.2.1.4 Lab - Configuring EtherChannel

hi friends welcome to all today we are going to see the lab activity configuring a third channel well here we can see our topology we will design this topology on our Cisco packet tracer also we can see a trussing table we will configure all these things here we can see the objectives in part of an configure basic switch settings in pata to configure pagp and in part we configure LACP also we will go through the background link aggregation allows the creation of logical links that are comprised of two or more physical links this provides increased throughput beyond using only one physical link link aggregation also provides redundancy if one of the links fails so in this lab we will configure a third channel a form of a link aggregation used in switch two networks we will configure a third channel using pot aggregation protocol that is pagp and link aggregation control protocol that is LACP here we can see the recorder resources so for this lab activity three switches we will use this code to nine six zero three pcs then alternate cables will come to path to one configure basic switch settings in part one you will set up the network topology and the configure basic settings such as the interface IP addresses then device access and passwords coming to step one cable the networks are shown in the topology attach the devices are shown in the topology diagram and the cable as a necessary well we are going to a builder this network topology on our cisco packet tracer here we are going to use three to nine six euro switches then we have three pcs NT devices and we are going to connect all these from faster Turin 0/6 to this PC eigh from faster toward 0 / 18 to this PC then faster thread 0 / 18 to this PC also we will rename all the devices as per our lab activity here this is s 1 here we can see this is yes 3 + DV how is - also we have the PC so this is PC - a here we have PC - C and here we have a PC - right B now we are going to connect our sutures here we can see a switch to switch we have to use a copper crossover from s1 you have 0 / 4 - f 0 / 4 + 2 f 0 / 3 - f 0 / 3 and from s 1 f 0 / 1 - f 0 / 1 else we have 0 stars - 3 of 0 stars - then from s 3 from F 0 / 1 - f 0 / 3 and the FCO stars - 2 F 0 / 4 here we will label here we are going to use pagp here we are going to use LACP and here you are going to use LS ep and Tennessee support channel one and this is for channel 2 and from his to 3s3 for channel 3 we will see the next step so here we can see initialize hunter reloaded the switches also we have to configure basic settings for each switch we have to do all these basic settings disable DNS lookup configure the device name is displayed in the topology encrypt the plaintext passwords then create MOTD banner then as in class as privileged exit password also a same cisco as the console and the vty password configure logging synchronous to prevent the console message from interrupting command entry shadow and all such words except the ports connected to PCs configure VLAN 99 and to name it a management configure VLAN 10 and a name it staff then we had to configure the supports with attach to the house as access ports in VLAN 10 I say in the IP addresses according to the addressing table or so copy the running configuration to startup configuration so all these basic configuration we are going to set on all these sutures s1 s2 and s3 first of all we will do this basic settings on the switch s1 enable configure terminal first of all we are going to disable DNS lookup no IP domain lookup and now we are going to set the device name this is s1 House name as s1 also we are going to encrypt all plaintext password using saris password encryption also we are going to set the banner motd here we will use our notarized excel see is prohibited now we will enable secret as class also we will set line console password Cisco Logan and we will give logging synchronous also we will set the password the line vty 0 to 15 password as a cisco Logan now we are going to shut down also supports except the ports connected to PCs coming to a topology here we can see this device PCA is connected to this Suchi s1 on the interface fastethernet co-star 6 so we are going to shut down all the ports except this port that is faster third 0 star 6 coming to the configuration yes one password is cisco enable password is class configure terminal we will go to the interface those we want to shut down we will go as a range faster towards euro / 5 we will go 0 / 1 till 5 because of 6 we should not shut down then we have a faster territorial / 7 till 20 for also we have a two gigabit ethernet 0/1 till two right we are going to share on all these ports now we are going to configure a VLAN we have to create this VLAN 99 and we have to give the name as management also we are going to create VLAN 10 name as a staff and next we can see configure the supports with attach the house as access ports in VLAN 10 so that is the faster Thor notice you are also r6 we have to go to that interface fastethernet 0/0 we are going to give such a port ahmad as access also support access VLAN 10 next we are going to assign the IP addresses according to the addressing table here we can see our addressing table coming to the configuration on a s1 we have to go to the interface VLAN 99 and we are going to set the IP address as per our a trussing table one ninety two dot one sixty eight dot ninety nine eleven and this happy to mask 255.255.255.0 and next we will save the configuration here we can see that copy running-config startup-config no going to do these basic settings on the next day such as to enable configure terminal no IP domain lookup service password encryption or so the house name is to banner motd another Royce Roxas is prohibited also we will enable the secret as class and line console password has Cisco Logan logging synchronous also we will go to line vty 0 to 15 and we will set the password as cisco login coming to a topology here we can see this PCB is connected to these layers to on the interface fastethernet 0/0 we can see that so we will shut down all the ports except these ports we will exit and we will go to those interfaces range fasterthan or 0 / 1 till 17 also faster thermit su ro / 19 till 24 also we have a gigabit authority 0 / 1 till 2 and here we are going to give shutdown now we are going to create the villain villain 99 nameís am an achievement also VLAN 10 named as staff also we are going to configure the supports of it attach the horse has access ports in VLAN 10 so we have to go to that interface fastethernet 0/1 here we are going to give us a chip or top mode as access support access VLAN 10 now we will assign the IP address as per our addressing table here we can see that yes to coming to the configuration here we have to go to that interface so VLAN 99 and we will set the IP address 192 dot 168 or $99 oh and the submit to mask 255.255.255.0 and we will give a copy running-config startup-config now we will do it on is 3 enable configure terminal no IP domain lookup hostname ancestry service password encryption banner motd unauthorized access is prohibited also we will enable secret as class also we'll set the password console password a Cisco Logan also we will give a logging synchronous and we will go to line vty 0 to 15 and we will set the password our Cisco login here our PC is connected to faster turn 0 / 18 on this asteroid so we are going to ash a turn all switch ports except this the faster turn 0 / 18 so we have to go to interface or a ninja faster turn 0 / 1 till 17 and faster until 0 / in 19 to 24 also we have a - Gigabit Ethernet 0 / 1 till 2 and we are going to shut down all these interfaces also we are going to create VLAN 99 named as management also VLAN 10 name stuff and we are going to configure the switch ports with attach the house us access ports in VLAN 10 so we have to go to that interface faster third 0 / 18 support the modest access switch port access a VLAN 10 now we will configure the IP address for the interface VLAN 19 an IP address 192 go to one sixty eight or 99 third thirteen also the subject to mask 255.255.255.0 copy running-config startup-config next is a step before configure the PCs I say Nyepi actresses to the PCs according to the addressing table here we can see the IP address offer each of PC so first of all we will come to PC a desktop IP configuration here we are going to give the IP address so one ninety two dot one sixty eight or ten door to one we will copy these archers and to here is the submitter mask now we will go to PC B here we can see that desktop IP configuration it's a 10.2 submit to mask also coming to PCC IP address 10.3 now we will come to party to configure pagp pagp is a cisco proprietary protocol for a link aggregation in party - a link between s1 and s3 will be configured using pH EP so coming to the topology here we can see s1 and s3 so in between we are going to configure this a pH EP coming to step one configure pagp or an s1 and s3 for a link between s1 and s3 configure the ports on s1 with the pagp desirable mod and the ports on s3 with the pagp ortho mode enabled the ports after pagp modes have been configured here we can see the command so that we have to give on all these switchers I mean s1 and s3 y/y Sport channel 1 then we have to give you know short command or so here we can see how an s3 channel group one more the auto so you'll do this configuration now before coming to the configuration we will check the interface here we can see this is faster third + 2 0 / we'll check that 0 / 4 also this interface is faster than 0 / 3 right so we will come to s1 first password is the cisco enable password is class so we will go to those interfaces configured terminal and interface as a range of fast eternal 0 / 3 & 4 here we are going to give a channel group channel group as so one more than specified or desirable here we can see creating a port channel interface for channel 1 now we are going to give an assured command so that this interfaces have become up but here we can see now it's down because the other end we have it to configure port channel coming to the other end on s3 here also the same ports fasterthan are 0 / 4 and 0 star 3 coming to s3 password cisco enable password is class here also we have to go to those interfaces as range if master turn are 0 / 3 & 4 we are going to create this channel group 1 and here the mode are specified Auto and here we are going to give you know shut command and 2 here we can see no these interfaces are up right now we can see the link between s1 and the s3 changed the color from amber to green here we can see the highlighter this line interface a port channel so this port channel one become an interface these two ports become a single interface now change will stay to up for the whole or interface for channel one changed state to up so we can see this message on our switch s3 here we can see that coming to step 2 examine the configuration on the port's currently the F 0 star 3 F 0 / 4 and this port channel 1 interfaces on both the s1 and s3 are in Access operational mode with the administrative mode in dynamic auto verify the configuration using the show run running config interface interface ID and it show interfaces interface ID support commands respectively the example configuration outputs for f0 slams 3 on s1 are as follows here we can see we are going to give this command and we are going to examine these ports here they given the output for this so show commands here we can see that a channel group 1 more desirable or sorter we can see operational mode static access member of a bundle the support channel 1 after giving this a show interface fastethernet 0/0 switch to port so we will try on our switch coming to our CGS one password is cisco enable password is class so here we are going to give a show running config and we will verify the interface zero stars three here we can see channel group two one more miserable also we will give the show command show interfaces faster third 0/3 such a port and to here we can see that such port enabled administrative more dynamic auto operational mode static access now we will verify on s3 password is cisco enable password is class show running config and we can see those interfaces 0 starts 3 and it 0 / 4 here we can see channel group 1 mode Auto also we will give the command to show interfaces first return 0 / 3 switch port and here we can see the details operation mode static access when we can give for the interface euro / for such a port enabled operational mode static access coming to step 3 verify that the ports have been aggregated by giving this a show command to show a third channel summary here itself they given the output here we can see that protocol is pagp and to here we can see those ports FS euro zone are 3 & a 0 / 4 this is a 4 channel 1 and here we can see the output of s3 we will verify on our switches coming to yes one show a tour channel summary and here we can see the output also coming to s3 show a tour channel summary here we can see that here we have a question where do the flags su and TP indicate in the internet summary here we can see that on this interface on bracket they given PP or so here we can see the flag yes you hear this FP indicates that the port's are bundled in a port channel also we can see this issue here s indicates that the port channel is a layer to a third channel or so this you means this a third channel is up and in use so together we can see this layer to ease up and in use next we will come to step before configure chunk ports after the ports have been aggregated commands are played at the port channel interface affect all the links that were bundled together manually configure the port channel one ports on s1 and s3 as trunk towards and as Windham tune 18 and 99 here we can see that we are going to give this port channel 1 as mod as a trunk also we can see we are going to set the native VLAN 99 on both switches s1 and s3 we will do that first of all we will do it on s1 password is cisco enable password is class configure terminal we will go to the interface for channel 1 and here we are going to give a supporter mode as a trunk also we are going to set the native VLAN 99 copy running-config startup-config now we will come to the switch s3 password Cisco enable password his class configure terminal we will go to the interface for channel 1 and here we are going to give the mod as a trunk also we are going to set this as native VLAN copy running-config startup config here we can see that we will give fast forward time right now we will come to step 5 verify that the ports are configured as trunk ports yeah you should the show or running config commands on s1 and the s3 what commands are listed for F 0 / 3 and the F 0 / 4 on both switches that means on s1 and destroy compare the results to the running configuration for the for channel 1 interface or recorder observation we will give the show commands on these switches first of all coming to es 1 show running config and you will verify the interfaces here we can see that you have 0 / 3 + 0 / 4 here we can see now the switchable trunk a native VLAN 99 and here we can see the mode is a trunk here also we can see that native VLAN 99 and switch port mode trunk also we will see port channel 1 VLAN 99 here we can see that interface port channel 1 here we can see such photo chunk in a DVD and this is what we configured so after configuring this for channel mode and native VLAN we can see automatically that bundled ports also are saying this mode as well as this native VLAN now we will verify on s3 show running config coming to the interfaces you have 0 / 3 & 0 / 4 here we can see that and here we can see the port channel this is what we configured an ATV and this murder trunk so when we configured the trunk commands were applied to the authorial the commands also affected the individual a link in this herb until we can see that on F 0 / 3 and the 0 / 4 coming to be we shoot the show interface the trunk and show a spanning tree commands on s1 and s3 what trunk port is listed what is the native VLAN and what is concluding result from the output from the show spanning tree output what is port cost and the port priority for the aggregated link we will check that coming to s1 here we are going to give a show interface assert trunk and to here we can see that the port is a port channel 1 here we can see that also we will verify on s3 show interfaces trunk and here we can see the port for channel 1 also we can see the native VLAN 99 status is trunking same thing can be on s 1 also natively 99 status is trunking now we will give the command to show spanning tree shows spanning tree and to here we can see that interface for channel 1 also we can see the cost here is 9 and the priority 128 coming to us 3 so a spanning tree and here also we can see that interface for channel 1 cost is 9 and the priority is 128 now we will come to part 3 configure LACP LACP is an open source protocol for a link aggregation developed by the I Triple E in part 3 the link between s1 and the s2 and the link between s2 and s3 will be configured using LACP also the individual links will be configured as the trunks before they are bundled together as a third channel here we can see the command what we have to you first of all we are going to create the support channel to on in between s1 and s2 here we can see those commands so we will do that first first of all we will do it on s1 configure terminal we will go to the interface as arranged faster third 0/1 and it - here we are going to make this mod as a trunk or so we have to make this native VLAN as 99 now we are going to create this channel group - and here we are going to give the mod as active and here we can see creating a poor channel interface for channel 2 now you are going to give in I should command here we can see these interfaces status change state - down because the other end we have to configure now we will do it on s - password configure terminal we have to go to the interfaces arranged faster third 0/100 to switch Oporto mortiser trunk support trunk a native VLAN 99 and you will create the channel group - also will give the mod as Plan C you here we can see LACP only so passive creating a poor channel interface poor channel - here we are going to give a no-shit command here we can see that you stay - up also we can see here this poor channel to change state - up right and here we can see that now it's a number we will give fast-forward time now we can see it's in green coming to step to verify that to the ports have been aggregated what protocol is this port channel 2 using for link aggregation here we use the LACP we will verify that which reports are aggregated to form the support channel 2 so we already given that that was a year 4 0 / 1 and the 0 starts - we will verify that using the show command record the command used to verify so we verify on s1 here we will give a show the third channel summary and here we can see this port channel to the protocol is LACP and also we can see the ports FA 0 / 1 & 0 starts - now we will verify Jana yes to show the third channel summary and here we can see the port channel - protocol is LACP and here we can see the ports FS 0 / 1 and the FS 0 / - coming to step 3 configure LACP between is 2 and the s3 configure the link between s2 and s3 as a poor channel 3 and we use LACP as the link aggregation protocol here we can see those commands but we have to set on these sutures - and here we can see the commands but we have to set on s3 so we will do this configuration now first of all we will do it on IES - here we can see those interfaces faster on co-star 3 and it 0 / 4 coming - yes - configure terminal and we will go to those interfaces first return 0 / 3 and a 4 switch port Ahmad as a trunk supporter Chunkin a TV land 99 and here we are going to create this channel group 3 and the mod active here we can see creating a portal interface for channel 3 now we will give an ocean command now the state is down because the other end we have it to configure coming to s3 before that we will check the interfaces here we can see it's f 0 / 2 and the 0 / 1 cisco glass configure terminal and we have to go to those interfaces fast return 0 / 1 and it to support the mode as a trunk switch for that chunk native VLAN 99 also we are going to create the channel group 3 and here the mode we will give as passive here we can see for channel this interface for channel 3 is created now we will give a no-shit command and here we can see these interfaces are up also we can see this interface port channel 3 change the stage 2 up also native VLAN mismatch also discovered here we can see now it's in amber we will give fast forward time yes verify that the third channel has formed we will verify that using the show command to show a tour channel summary and here we can see that port channel 3 LACP is the protocol and here we can see the ports coming to s3 so third channel summary and here we can see that poor channel 3 protocol is LACP and here we can see the ports coming to step 4 verify in the 2 interconnectivity verify that all devices can ping each other within the same VLAN if not the troubleshoot until there is nt to enter connectivity it may be necessary to disable the PC firewall anyway here we are using this a cisco packet tracer so no need to worry about the firewall so in a real-time when we implement we have to take care of this firewall we must disable this firewall to get this a pink so now we will verify this NT to end connectivity we will ping from this PC a to PCB and the PCC coming to PC a desktop command prompt ping to 192 door to one sixty eight or ten door 2 here we can see we are getting the replay now we will ping to PCC that is 10.3 here we can see we are getting the replay coming to the reflection here we got a question of what could prevent a third channels from forming well there may be some reasons like a configuration mismatch such as a chanc port on one end we configured and other NTV configured access port then this third channel may not form also when we give different aggregation protocols under different port speed or duplex the soul will prevent the formation of a third channel will have that soul in this a lab activity that is configuring a third channel so friend CP how and need to out in this packet race or activity please comment below also if you liked my video give a thump and share to your friends and
