Cisco router--HP procurve duplex/speed issue

Unanswered Question

I have a cisco 3800 series router connected on the LAN side to an HP ProCurve 4000m switch. I can only get this connection to come 'up' at 10half (for speed/duplex) if I set both to auto, it negotiates to 10half. All other settings and the interface goes 'down' and will not come back up. I have tried new cables and other ports on the switch as well. Same issue. Any ideas?

We are running a Cisco 3825 Router with the following configuration:

interface GigabitEthernet0/1

description $FW_INSIDE$$ETH-LAN$

ip address x.x.x.x

no ip redirects

no ip unreachables

no ip proxy-arp

ip route-cache flow

load-interval 30

duplex auto

speed auto

media-type rj45

negotiation auto

no mop enabled


... and the 4000m has the following setup:

Type: 10/100

Intrusion Alert: No

Enabled: Yes

Status: Up

Mode: 100FDx

Flow Ctrl: off

Bcast Limit: 0

.... hope this helps.

you could try adjusting the carrier-delay time on the cisco box (under the interface config mode) after locking both end to say 100/Full.


config t

interface g0/1

!Generally you want to raise the time

carrier-delay 4

Please rate if this helps.
