FEC between DL580 servers and cat2924/cat5509 switches

[scolombo]

We have four servers ( compaq dl580 ) with two Gigabit NIC each.

Two of them are connected to a 2924 and the other two to a cat 5509.

We'd like to configure each server with FEC .

For the 2924 I did the following configuration

interface Port-channel2

switchport mode trunk

flowcontrol send off

interface FastEthernet0/4

description gdbo01CLN2-1

switchport mode trunk

no cdp enable

channel-group 2 mode on

!

!

interface FastEthernet0/6

description gdbo01CLN2-2

switchport mode trunk

no cdp enable

channel-group 2 mode on

Is this correct ? Do I need to add anything ?

Which configuration is needed to do the same on the cat 5509 ?

thanks

This is correct, except that you should not set these ports to trunk. Make them acess ports instead.

with us, it works like this for about a year now:

interface Port-channel2

description

no ip address

switchport

switchport access vlan 14

interface FastEthernet5/47

description Channel2

no ip address

logging event link-status

switchport

switchport access vlan 14

no cdp enable

spanning-tree portfast

channel-group 2 mode on

!

interface FastEthernet5/48

description Channel2

no ip address

logging event link-status

switchport

switchport access vlan 14

no cdp enable

spanning-tree portfast

channel-group 2 mode on

With a C5509 (CatOS) I would like to help you but unfortunately I cannot spare the the time to check this out.

Hi Leo ,

thanks for your input .

Just a question , as I'm not so familiar with VLAN yet . We have just the default VLAN1 in our domain so can I just put "Switchport access Vlan 1" in the ethernet interfaces config?

Can you spare a few info regarding the trunk?

I thought trunking was the only method to have the bandwith doubled, with you configuration do I have only fault tolerance or bandwith aggregation too ?

thanks again
