FEC between Cisco 2900 XL serien and HP Procurve 4108


Hi everyone. I'm trying to configure FEC between a cisco catalyst 2900 xl series and a HP Procurve 4108 where in the specifications says FEC is supported but I'm not able to do so:

The way that I configure in the cisco two ports to form a fastetherchannel is:

int fa0/23

speed 100

duplex full

port group 1

int fa0/24

speed 100

duplex full

port group 1

In the HP the way is something like that :

trunk c13-c14 trk3 FEC

interface c13

speed-duplex 100-full

no lacp

interface c14

speed-duplex 100-full

no lacp

If I show cdp nei:

cisco#sh cdp nei

Capability Codes: R - Router, T - Trans Bridge, B - Source Route Bridge

S - Switch, H - Host, I - IGMP, r - Repeater

Device ID Local Intrfce Holdtme Capability Platform Port ID

bmsw11(0004ea-3dbFas 0/23 125 S HP 4108GL Trk3

only one port is working (fa0/24 is down and is already connected)

the keepalive is not configured

At the HP 4108, only one port has link once the FEC is working

hp# sh cdp nei

CDP neigbors information

Port Device ID | Platform Capability

---- ----------------------------- + ---------------------------- -----------

Trk3 cisco | cisco WS-C2924-XL B S

Can anyone tell what is going wrong or how must I configure it to work properly?

Thanks it advance

Your config on the Cisco side looks fine. You might need to get both vendors on the phone.
