4.2.1.3 Packet Tracer - Configuring EtherChannel

hi friends welcome to this video on packetize our activity configuring a third channel in this packet tracer activity we are going to configure a basic switch settings then configure and a third channel with a cisco pagp then we will configure an eighth-note 2.3 ad LACP a third channel and we will configure a redundant a third channel link in this topology we can see researchers have been installed so here we can see redundant up links between these switches so here only one of these links could be used otherwise a bridging loop might occur so however using only one link utilizes only half of the available bandwidth the third channel allows up to eight redundant links to be bundled together into one logical link so how we will do that we are going to see in this packet tracer activity here we are going to use two protocol one is P AGP this is nothing but the third aggregation protocol it says Cisco a third channel protocol also we are going to use LACP that is a link aggregation control protocol now we will come to part two one configure basic settings configure basic switch parameters assign each switch a host name according to the topology diagram well here we can see that s 1 s 2 and s 3 so here we are going to set the hostname will come to s1 first enable configure terminal here we are going to set the hostname of n1 XT we will go to yes to enable configure terminal here we are going to set the hostname of s2 you go to s3 enable configure terminal hostname as history next please configure all record ports of strengths depending on the connections between devices if the ports are configured with dynamic author mode and you do not set the mode of the ports to trunk the links do not form trunks and remain access ports the default mode on a 2 and 6 zeros which is a dynamic photo right so we will configure all the ports as trunks the topology here we can see on s1 the interface a Gigabit Ethernet 0 / 1 & 0 / 2 also we can see the interfaces faster per net 0 / 21 and 22 so these ports we are going to convert to the mode as trunk so you come to s1 right ok we will go to the interface we will give the range Gigabit Ethernet to 0 / 1 till 2 yes here we are going to give a support more trunk also we are going to the range of interfaces interface range faster per net we have 0 / 21 to 22 and to here we are going to give the support mode of trunk now we will check on s2 here we can see the interface of Gigabit Ethernet 0 / 1 + 0 / 2 is connecting to s1 and here we can see faster / + 0 + 23 + 0 / 24 is connecting to u3 yes we will do the configuration here now we will go to the interface range Gigabit Ethernet - 0 / one two two and two we are going to give the switch for the mode as a trunk now we will go to the interface or range faster power to zero slash twenty three to twenty four and two here we are going to give such a porter more - uncle now we will come to es three here we can see faster third 0 / 21 and 22 is connected to s 1 + 23 24 is connected to s 2 so we will come to the configuration your 3 right here we are going to the interface a range of interfaces so fast learner - 0 / 21 to 24 here we are going to give a switch about the mode as a trunk yes before we we had seen in not about dynamic auto mode so if it is enabled once you enable that chunk on the one side of the switch automatically the other side also will be become this trunk mode so here we can do only you know I mean we may have to do these two these four interfaces and these two interfaces so remaining will be automatically converted to the mode trunk now we will come to party to configure and a third channel with a cisco pagp they are given a note here when configuring a third channels it is recommended to shut down the physical thoughts being grouped on both devices before configuring them into channel groups otherwise the approach channel msconfig guard may place these ports into error disabled state the ports and the poor channels can be re-enabled after authority is configured well we will do that now we will come to a step 1 for channel 1 the first athos channel created for this activity aggregates ports yeah we have seen that the pagp pours faster through node 0 / 22 and 21 between s1 and s3 yes here we can see that ports 21 and 22 here is use the show interface of trunk command to ensure that you have an active at wrangling for those two links right we will verify that on s1 enable here we are going to give a show interface a trunk and two here we can see that two interfaces faster thread 0 / 21 and 22 e search ranking the next Lisa on both switches other ports faster 3rd + 0 / 21 and 22 - for channel 1 with the channel group 1 mode desirable yes so here we are going to give the motor so desirable the more desirable option enables the substitute actively negotiate to form a PA GP link right we will do this configuration on s1 now coming to yes 1 right so we'll go to configure terminal we are going to the interface range we have faster currency rose last 21 and 22 here first of all we are going to shut down this yes now we are going to create the channel group with the number 1 yes and they specified the mode acid discernible here we here we can see the different modes act you out or desirable or one passive etc so here we are going to give a specified that is a desirable yes now we are going to give a no-shit command now we will do it on f3 enable configure terminal we are going to the interface range faster third net zero slash twenty one to twenty two you will shut down it so we are going to give a channel group as one and the mode is so desirable now we are going to give the no-shit command yes the topology we can see the changes on both side we can see the links are up next is the configure the logical interface to become a trunk by first answering the interface port channel then the number command and then the suit sport mode trunk command add this configuration to both switches yes we will do this now we will come to yes one first here we will exit from here and here we are going to interface port channel one then we will give a support or more desert trunk now we will go to a three so we are going to exits and we will go to interface for channel one and two here we are going to give you such a porter mode asset trunk now we will come to step to verify for channel one status you should show a third channel summary command to verify that the third channel is working on both switchers this command displays the type of auto channel the poor's utilized and two port States well we will verify the support channel one status on both switches first we will come to s1 so here we will give a show a third channel summary right yes here we can see the details number of channel groups use 1 number of aggregators 1 & 2 here we can see the other details we are using protocol pagp and the ports are 0 / 21 and 0 / 22 well now we will come to su 2 3 sir will give a show a third channel summary here also we can see the details next is mmm if they throw channel does not come up shut down the physical interfaces on both ends of the approach channel and then bring them back up again this involves using a shutdown command on those interfaces followed by a notional command a few seconds later anyway here it was working for us and the show interfaces trunk and show spanning tree commands also show the port channel as one logical link well we will check these two show commands on these two sutures first of all we will come to yes one right here we are going to give a show interfaces such trunk and to be able to check for the port yes here we can see that 4 to 1 that is trunking yes ok but now we will give next to command the show spanning tree here also we can see this they are talking about the port 2 1 yes now we will go to part 3 configure an eighth-note 2.3 adls CPI third channel configure for channel 2 in 2002 i to plea released 8 no 2.3 ad which is an open standard version of a third channel right what we have seen previously is a cisco proprietary protocol using the previous commands to configure the link between s1 and s2 on ports g 0 / 1 + 2 G 0 / 2 as an Alessi P approach we must use a different port channel number on s1 than one because you already use that in the previous step yes already we have used this one to configure a ports analyst L is CP use the interface configuration mode channel group the number we have to specify mod active that's the command what we have to give actually more indicates that the switch actively tries to negotiate that the link of LS CP as opposed to pagp right here we are going to configure between s1 and s2 here we can see the interfaces Gigabit different 0 / 1 and 0 / 2 and 2 other side also we can see Gigabit Ethernet 0 / 1 and 0 / - first of all you will come to yes one right here we are going to give a configure terminal we will go to the interface range e Gigabit Ethernet 0 / 1 - - first of all we will shutdown it then we will give a channel group we are going to specify the number - modest active now we are going to keep a no-shit command here yes now we will exit and we will go to this portal interface for channel 2 and we will give such a port the mode our trunk we will come to as to enable configure terminal here we are going to the interface or range Gigabit Ethernet 0 / 1 - 2 and the first of all we are going to shut down it then we will create the channel group here we are going to create the group of true as the same what we greater on s1 and tamati is active now we will give a no-shit command also we have to go to this support channel interface the interface for channel 2 and we are going to give a supporter mode of trunk no here we can see between s1 and s2 the interfaces on both sides are the links are up now we will come to step to verify poor channels to status use the so commands from path 1 step 2 to verify the status of ports channel to look for the protocol used by each port yes so here we are going to verify the port channel to status we will come to s1 here we will give us to show a third channel summary and till we can check it yes here we can see the both protocols on s1 this is the protocol what we created first and you know we created LS CT the interfaces here the ports we can see these are B the current 0 / 1 & 0 / 2 now we will give a show interfaces trunk here we can see 42 is also trunking now we will give a show spanning tree yes here we can see the details now we will come to part two for configure a repentant throw channel link let's step 1 configure port channel 3 there are various ways to enter the channel group number mode command interface arranged faster third 0 / 23 to 24 then they are giving the child group 3 then mode here we can see the different modes already shown that right now on suture is to add ports yes 0 / 23 and 0/24 to port channel 3 with the channel group 3 mod path see you command the passive option indicates that you want the switch to use LACP only if another LACP device is detected statically configured for channel 3 as a trunk interface well we will come to this configuration now we will come to years to right configure terminal we are going to the interface range faster third 0 / 23 to 24 we will shutdown it first then we will create the channel group 3 the mode as passive and we will give a no-shit command here also we will go to this interface interface for channel 3 and we will give the support the modest chunk now 150 s 3 are the port's faster third 0 / 23 and 24 - for channel 3 with the channel group 3 mode as active command the active option indicates that you want the switch to use LACP unconditionally statically configured for channel 3 as a trunk interface yes we will do it on s3 coming to s3 enable configure terminal here to go to the interface range faster per node 0 / 23 - 24 first we will shutdown it shut on it first yes now we will create the channel group / 3 the mode active yes now we will give no command then we have to go to that interface for channel 3 so interface for channel 3 and we are going to give the support mode us a trunk now we will come to step to verify port channel pre status use the show command from part 1 step 2 to verify the status of port channel 3 look for the protocol used by each port yes you will do this now coming two years to here we are going to give a show we have a third channel summary yes here we can see that and the portal so we can see right we see show interface a trunk yes we can see the details here also we will give a show spanning tree yes now we will go to s3 show the throat channel summary yes here we can see the details with the protocols and thoughts so interface the trunk yes these are all trunking and to be how short spanning tree yes yes now we will come to for channel 2 is not operate you because planning tree protocol plays some ports into blocking mode unfortunately those ports were gigabit ports to restore these ports configure s1 to be primary route for we land one or set the priority to 2 4 5 7 6 using this topology here we can see on s1 because of spanning tree protocol for channel 2 ease and not operate you here and to these blocked thoughts our gigabit ports so now what we will do we will restore these ports for that we will come to s1 Nabal configured terminal here we are going to give a spanning tree we learn one road primary or we can give this command spanning tree we learn one we can specify the priority as they are given that 2 4 5 7 6 right in order to give these both command say anyone can be given no we can see in the topology the block the ports is a come to you 3 previously it was on s1 and it was blocking this gigabit port now it is blocking the faster Thermage here we can see the completion status 100 out of 100 also this packet tracer activity is very easy also it is very important terms if you have any doubt in this a third channel please comment below also if you like my video give a thump and don't forget to subscribe the channel so that you will get latest uploading video info inter Gmail bye bye
