Regarding Etherchannel

[Sanjay shivaji Nalawade]

Hello,

In the Data Center ,we have two Cisco-4507  switches.

Two servers ,Server 1 & Server 2 are connected to these core Switches

With two interfaces connected to separate switches.

At server end, Etherchannel is configured.

Can we configure the etherchannel at switch end with two interfaces of each server

are connected to  two different switches?

Can we configure LACP for this?

Regards,

Sanjay Nalawade

What you are trying to do is possible with Cisco Virtual Switching System using MultiChassis EtherChannel. However, I think VSS is only for Cisco Catalyst 6500.

Hello Sanjay,

as explained by Danny you cannot do this with your current standalone switches.

You need to configure the server for active/passive NIC teaming or you need to terminate both NICs on the same switch.

VSS on C6500, or stacking on stackable switches like C3750 allows for the proposed setup.

Hope to help
