Ether channel Group number

Hi all,

Is there any issues in creating  duplicate ether channel group number  in the same network but different switch.

For example

I have a core switch connecting two buildings which have 3 access layer switches

First Building

Switch 1 :Ether channel group 1 between core switch and Switch 1

Switch  2 : Ether channel group 12 between Switch 1 And Switch 2

Second Building

Switch 1 :Ether channel group 2 between core switch and Switch 1

Switch  2 : Ether channel  group 12 between Switch 1 And Switch 2

My question is that is there any issue having same ether channel group number 12 in second building or it should be different number.

Please advice me

Etherchannel group numbers are local to the switch so you can use the same number on different switches.

Re: Ether channel Group number

Hi John ,

Thanks for your  response.

So channel group is local to switch But i have a problem in my network .

In my network layer 2   ether channel using  channel group mode on  from Core switch to Edge switches and  between local switch 1 ---> Switch 2 and between Switch 2 ----->switch 3.core switch ip address is  192.168.255.1 .so i gave default-gateway as192.168.255.1 all of the three Local switches.My problem is that i am not able to ping core switch ip from the switch 3 also i cannot ping switch 3 from any of the switches.I verified ether channel it shows up and connected and also it is trunking.Till switch 2 everything is fine I can ping all of the switches.Do i need to give default gateway in all of the three switches or i need to give  only   the switch i am connecting core switch.

You should give a default-gateway to your edge switches although if you are pinging from within the same subnet they should respond anyway.
