Etherchannel mode on question

[Wilson Kwok]

Hello all,

I'm trying to setup etherchannel between two layer2 swtich in Cisco Packet Tacker, two switch fa0/1 and fa0/2 for etherchannel with trunk (mode on), and fa0/3 connected PC with access vlan 10.

But show etherchannel port both ports is down, can someone help ?

Can you send what you configured?

It should be a pretty simple task, just do "channel-group x mode on" on both sides, make sure physical and logical interfaces are "no shut" 

[Mitesh Manwatkar]

The sample config per port shud b like this:

interface fa0/1

switchport mode trunk

switchport trunk allowed vlan 10

channel-group 1 mode on

Once u do it on per port per switch it will automatically create port channel 1 (since channel-group is 1 here) on both the switches.

Regards.
