Troubleshooting Installation Issues

Problem

Solution

 

 

SCP Keepalive Failure

• The SP and the MSFC periodically poll each

 

individual LC in the chassis for its health via

 

SCP keepalives. Each LC in turn, must

 

respond within a certain amount of time

 

(dictated by the SCP keepalive timer) to

 

indicate its health. If the LC fails to respond

 

to the keepalives within the stipulated period

 

of time, the MSFC assumes that there is an

 

issue with the LC and power cycles it. When

 

the LC comes back online, the SCP

 

keepalives are resumed.

 

• A line card might be unable to respond to the

 

scp keepalives under situations of extreme

 

stress when the CPU is busy with higher

 

priority tasks, such as packet switching,

 

interrupt processing etc.

 

• Execute the show scp status and show scp

 

line cards command to gather detailed

 

information about the SCP process and health

 

of each LC. A show diagbus indicates any

 

errors with the LC.

 

• Execute the test scp line card keepalive

 

disable exec command on the RP console to

 

disable the SCP keepalive timer and debug

 

LC issues. To prevent the LC from being

 

power cycled and losing its information,

 

ensure that you disable the SCP keepalives

 

for some time.

 

 

Line Card in ROM monitor

• Linecards have a ROMMON variable

 

DL_DISABLE depending on which line card

 

auto boots or remains in ROMMON waiting

 

for manual boot. If DL_DISABLE is set to 0,

 

line card does not boot automatically but

 

waits for the user to manually boot with

 

respective line card image (from line card

 

console). Line card auto boots only if

 

DL_DISABLE=1. When DL_DISABLE=0

 

and line card doe not initialize, SCP

 

Keepalive Failure messages appear on RP

 

console.
