SNMP Walk Acceleration for linkServiceUsage Queries
The time taken for the SNMP walk on any of the linkServiceUsage queries is reduced considerably.
The SNMP walk acceleration enables Cisco SCE 8000 device to perform SNMP queries for LinkUsage
MIB queries in background and cache the results. This may result in more CPU utilization.
The following queries are accelerated:
•
snmpbulkwalk on linkServiceUsageUpVolume
•
snmpbulkwalk on linkServiceUsageDownVolume
•
snmpbulkwalk on linkServiceUsageNumSessions
•
snmpbulkwalk on linkServiceUsageDuration
•
snmpbulkwalk on linkServiceUsageConcurrentSessions
•
snmpbulkwalk on linkServiceUsageActiveSubscribers
•
snmpwalk on complete linkServiceUsageTable
Use the following commands to enable, disable, and show the SNMP query acceleration for
linkServiceUsage queries:
•
snmp-server accelerate-query
•
show snmp-server accelerate-query
How to Enable SNMP Query Acceleration
From the SCE(config)#> prompt, type:
