Use this task to enable persistent storage for SNMP MIB indices and cache QoS MIB data across process restarts, switchovers, and device reloads.
Ensure key SNMP MIB data and indices retain their values across process interruptions, improving management reliability and reducing re-indexing overhead.
In many SNMP MIB tables, indices serve as unique identifiers and are often mapped to internal data structures. For instance, ENTITY-MIB and CISCO-CLASS-BASED-QOS-MIB typically require persistent indices to avoid increased processing during network management tasks. Caching statistics for QoS MIBs helps optimize query response times and CPU utilization.
Before you begin
Identify which MIB tables require persistent indexing and caching in your deployment scenario.
Procedure
| 1. | (Optional) Enable persistent storage of the CISCO-CLASS-BASED-QOS-MIB data. Example: |
|
| 2. | (Optional) Enable QoS MIB caching with a specified cache refresh time. Example: |
|
| 3. | (Optional) Enable QoS MIB caching with a limited number of service policies to cache. Example: |
|
| 4. | Enables ifIndex persistence globally on all Simple Network Management Protocol (SNMP) interfaces. Example: |
MIB index values and QoS MIB statistics persist through process restarts, switchovers, and device reloads. This ensures consistent network monitoring and reduces discovery time for SNMP management systems.
