Command Modes Interface configuration mode
Usage Guidelines I nterface index persistence occurs w hen ifIndex values in the IF-MIB persist a cross reboots and allow
for consistent identification of specific interfaces using SNMP.
The snmp ifindex persist interface configuration command enables and disables ifIndex persistence for
individual entries (that corr espond to individual inte rfaces) in the ifIndex table of the IF-MIB.
The snmp-server ifindex persist global configuration command enabl es and disables ifIndex
persistence for all interfaces on the routing device. This action applies only to interfaces that have
ifDescr and ifIndex entries in the ifIndex table of the IF-MIB.
Examples This exampl e shows how to enable ifIndex pe rsistence for interface FastEthernet 1/1 only :
Router(config)# interface fastethernet 1/1
Router(config-if)# snmp ifindex persist
Router(config-if)# exit
This example shows how to enable ifIndex persistence for all interfaces, and then disable ifIndex
persistence for interfac e FastEthernet 1/1 only:
Router(config)# snmp-server ifindex persist
Router(config)# interface fastethernet 1/1
Router(config-if)# no snmp ifindex persist
Router(config-if)# exit
