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?

Hello,

Pls ignore previous query.

In our Data Center ,we are having two Cisco-4507 switches.

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

Each server have 4 ports ,With two interfaces connected to one switch &

two interfaces are connected to second switch.

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?

Can we get throughput of 4 Gbps ?

Hello Sanjay,

you can configure two separated LACP bundles of two ports each, with one acting as primary and one as backup.

On server side is again an active/passive teaming made of two bundles of two ports each.

To get a 4 Gbps bundle working you should connect all 4 NICs to the same switch.

Hope to help

if you have 2 links going from server to one switch or if its VSS or 3750 stack then you can form an etherchannel or else if its completly 2 diff switches on the other side of the server then you cant form a channel on the switch side.

Hope that hepls.
