Usage Guidelines Interface index persistence oc curs when ifIndex values in t he IF-MIB persist across reboots and allow
for consistent identification of specific interfaces using SNMP.
The snmp-server ifindex persist global configuration command does not override the interface-specific
configuration. To override the interface-specific configuration of ifIndex persistence, enter the no snmp
ifindex persist and snmp ifindex clear interface configuration commands.
Entering the no snmp-server ifindex persist global configuration command enables and disables
ifIndex persistence for all interfaces on the routing device using ifDescr and ifIndex entries in the ifIndex
table of the IF-MIB.
Examples This example shows how to enable ifIndex persistence for a ll interfaces:
Router(config)# snmp-server ifindex persist
