trunking between cisco 2900 and HP 4108

Hi everyone this is Albert. Could anyone help me with this issue?

I'm trying to configure trunking with FastEtherChannel (2 ports) between a cisco catalyst 2900 xl series and a HP Procurve 4108 gl 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

hp(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

Then I have tried to configure the cisco 2900 as follows:

int fa0/23

speed 100

duplex full

port group 1

switchport trunk encapsulation dot1q

switchport mode trunk

int fa0/24

speed 100

duplex full

port group 1

switchport trunk encapsulation dot1q

switchport mode trunk

but the result was de same. I'm sure the spanning-tree is disable at both switches and there's only the default vlan defined.

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

Thanks it advance

Albert
