Troubleshooting the Link Interface Subsystem

Symptom

Diagnostic Action

Possible Cause

Possible Solution

•

Link is down. (LINK
LED not lit)

•

Status is WARNING
(Status LED is
flashing orange)

•

Output counters not
incrementing.

CLI command:

•

show interface
FastEthernet 0/#
counters

Connector is not connected
to the platform or to the
network.

Reconnect the cable to the FE port
and to network.

FE cable is broken.

Reconnect / replace the cable to the
FE port.

If FE counters are incrementing, this
indicates LED problem. Contact
customer support.

CLI commands:

show interface

FastEthernet 0/#
counters

Check output of this
command for: “In good
unicast packet” and “Out
unicast packet”. These
counters should be constantly
incrementing.

Auto-negotiation may be
incorrectly configured.

Check auto-negotiation configuration
in the

SCE 2000

and in its peers.

•

FE link is up (FE
interface link LED is
continuous green and
FE interface Tx LED
is flashing)

•

Peer does not receive
traffic from

SCE 2000

CLI commands:

•

show interface
FastEthernet 0/#
counters

Check output of this
command for: “Out unicast
packet”. This counter should
be constantly incrementing.

show interface
FastEthernet 0/#

Auto-negotiation is disabled
at the

SCE 2000

but enabled

at peer.

Check auto-negotiation configuration
in the

SCE 2000

and in peer.

•

FE link is up (FE
interface link LED is
continuous green)

•

No traffic received
(FE interface Rx LED
is not flashing)

No traffic is being
transmitted to the

SCE 2000

from its peers.

Check traffic connection at peer.
