no snmp-server ifindex persist compress
Syntax Description This command has no arguments or keywords.
Defaults Disabled
Command Modes Global configuration mode.
Command History
Usage Guidelines This command is hidden on Supervisor Engine V and later supervisor engines because the ifIndex table
is always in a compressed format on those supervisor engines.
At bootup, if the nvram:ifIndex-table.gz file (the ifIndex table ina compressed format) is present on a
Supervisor Engine II+, Supervisor Engine III, or Supervisor Engine IV, the snmp-server ifindex persist
compress command is automatically run even if the startup-config file does not have this configuration.
Examples This example shows how to enable compression of the ifIndex table:
Router(config)# snmp-server ifindex persist compress
This example shows how to disable compression of the ifIndex table:
Router(config)# no snmp-server ifindex persist compress
