I have 4 HP 2848s trunked into a CISCO 4510 using dual gig uplinks and FEC set on the HP side.  We just got a new 2848 switch which has the most current firmware on it and they no longer support FEC.

I can't get the new switch to pass traffic.  The CISCO shows the links as up but the protocol is down.

So I can figure out how to get the link working with my cisco or try to "down rev the HP."  Any thoughts?

My cisco config below looks just like the other switches trunks except each switch has its own port channel number.

Here's my cisco config:

interface Port-channel5
 switchport
 switchport trunk encapsulation dot1q
 switchport trunk allowed vlan 1,50,100,105
 switchport mode trunk
 switchport nonegotiate

interface GigabitEthernet7/47
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,10,20,50
switchport mode trunk
channel-group 5 mode on

interface GigabitEthernet7/48
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 1,10,20,50
switchport mode trunk
channel-group 5 mode on
