Etherchannel on CSS?

[mcristobal]

Brief question..:

Can I configure Etherchannel on the css 11501?

[Zach Seils]

EtherChannel is not supported on the CSS.

Could that be a trick question though? What if you set up the network like this?...

WAN---->Firewall--->CSS---->Catalyst 6509 --[etherchannel]---> Webservers

Could that be a trick question though? What if you didn't do etherchannel on the CSS box because it doesn't support it, but you do it on a switch after the CSS box? Don't they have a CSS card out for the 6500 series switches? If so, you could do etherchannel with that, you just do it on the switch ports. What if you set up the network like this?...

WAN---->Firewall--->CSS---->Catalyst 6509 --[etherchannel]---> Webservers

or

WAN--->Firewall----Catalyst 6509 w/CSS module ---> Webservers

The the question would have been:

"Can I configure EtherChannel on the Catalyst 6500?"

:-))

There is a Content Switching Module (CSM) for the Catalyst, which has a 4 Gbps EtherChannel connection to the switch fabric.

LOL! Yeah your right. I kinda was asking a question and solving a question.

I thought they had a module for the 6500. Good to know.

Thanks Zach.

if you go for such a design, make sure to use a Gig interface between CSS and cat6509 and FastE etherchannel between Cat6k and servers.

If you have a bigger pipes from server to CSS you will get congestion.
