SNMP ifindex Persistence

The SNMP ifIndex persistence feature is always enabled. With ifIndex persistence, the ifIndex value of
the port and VLAN is always retained and used after these occurrences:

•
•
For Fast EtherChannel and Gigabit EtherChannel interfaces, the ifIndex value is only retained and used

Understanding How SNMPv1 and SNMPv2c Work

The components of SNMPv1 and SNMPv2c network management fall into three categories:

Using Managed Devices

Catalyst 6500 series switches are managed devices that support the SNMP network management with
these features:

OL-8978-04
Each user belongs to a group.
A group defines the access policy for a set of users.
SNMP objects access an access policy for reading, writing, and creating.
A group determines the list of notifications that its users can receive.
A group also defines the security model and security level for its users.
Switch reboot
High-availability switchover
Software upgrade
Module reset
Module removal and insertion of the same type of module
Managed devices (such as a switch)
SNMP agents and MIBs, including the Remote Monitoring (RMON) MIBs, which run on managed
devices
SNMP network management applications, such as CiscoWorks2000, which communicate with the
agents to get the statistics and the alerts from the managed devices. See the
CiscoWorks2000" section on page 47-6
An SNMP management application, together with the computer it runs on, is called a
Note
Network Management System (NMS).
