How can I configure an OID on 7200

We are using BVI interfaces on 7200 and MRTG to view

statistics on thise BVI interfaces.

I have the following problems:

When I create the interface BVI 100, the router allocate an OID *.100 and when the router reboots,

the OID of the interface BVI 100 is changed to *.1

If I create an other interface BVI 200, the router allocate an OID *.200 and if the router reboots the OID is changed to *.2 etc.

So after the reboot, the MRTG don't work, because the

OID of the interface BVI had changed.

My question is: Can I configure the OID of the interface BVI 100 to *.100?

Thanks you for you helps.

Re: How can I configure an OID on 7200

From the Cisco documentation:

Interface Index Persistence

This feature module describes the Interface Index Persistence feature introduced in Cisco IOS Release 12.1(5)T. This enhancement allows interfaces to be identified with unique values which will remain constant even when a device is rebooted. These interface identification values are used for network monitoring and management using Simple Network Management Protocol (SNMP).

Enabling IfIndex Persistence on All Interfaces Example

In the following example, ifIndex persistence is enabled for all interfaces:

router(config)# snmp-server ifindex persist

Enabling IfIndex Persistence on a Specific Interface Example

In the following example, ifIndex persistence is enabled for interface ethernet 0/1 only:

router(config)# interface ethernet 0/1

router(config-if)# snmp ifindex persist

router(config-if)# exit

This should resolve the issue.
