Creating port-channel subinterface on a 4510RE

[wilfred malana]

Just received a 4510RE w/ SUP7s which will start rolling out at the access layer in place of 6500 chassis. I ran into an issue creating port-channel interface with the 10GigE uplinks. Sitching the port-channel to L2 or L3 doesn't seem to make a difference.

Here's a snippet of sho ver..

Is it a licensing issue?

I am not sure what you mean by "

Sitching the port-channel to L2 or L3 doesn't seem to make a difference."

can you explain?

should not be a license issue

[wilfred malana]

Sorry.

Sitching , I meant switching .... or I guess the better wording would be "making it"

Making the port-channel a "switchport" (L2) or "no switchport" (L3)

Can you post your config?

A layer-2 Etherchannel can be in an access mode or trunk mode.  A layer-3 Etherchannesl is a routed Etherchannel with IP address.

It's default config right now.

I can create interface port-channel 1 but when try to create interface port-channel 1.200  it fails. Like it doesn;t know how to deal with sub-interfaces.

ROC-RS4510RE-AU-E130(config)#interface port-channel 1 ?

ROC-RS4510RE-AU-E130(config)#interface port-channel 1.200

ROC-RS4510RE-AU-E130(config)#interface port-channel 1.200

I have never seen a "sub-interface" port channel before.

I do this all the time on the 6500 platform w/sup32s and sup720s.  I appreciate your help.

  Normally you do not use subinterfaces on a trunk on  L3 etherchannels . Normally that is used for router on a stick scenarios on like ISR"s . You use vlans and SVI"s across a standard trunk setup for L3 etherchannels.  I don't believe it will work , if its rejecting the commands thats another indication it will not work.

int port-channel 1

switchport

switchport trunk encapsulation dot1q

switchport trunk native vlan X

switchport trunk allowed vlan x,x,x,x

switchport mode dynamic desirable

That's what I had do to. Just attempting tk standardized configs on all my access layer switches.

Thanks a lot for the tips.
