SolutionPossible CauseProblem

1. Check the CPU usage using

show process cpu history

2. Execute test snmp cpu-stats

start, wait for

SNMP-3-RESPONSE_DELAYED

error message to appear again,

then check the output of show

snmp cpu-stats to see if the

OID in

SNMP-3-RESPONSE_DELAYED

displays a big value. If so,

contact cBR support, otherwise,

it is a CPU issue, please check

the reason why the CPU usage

is high.

SNMP process is consumed by 5

seconds to get an OID.

SNMP-3-RESPONSE_DELAYED

error message in show logging
