chasEntityChangeCounter
Module: DECHUB900-CHASSIS-MIB-V3-0
OID (symbolic): DECHUB900-CHASSIS-MIB-V3-0::chasEntityChangeCounter
OID (numeric): 1.3.6.1.4.1.36.2.18.11.1.1.1.2.4.1.2
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: A counter which is incremented whenever entity table entries, for a particular slot, are added, deleted, or changed. Adds and deletes occur when:
o IP addresses are added, o IP addresses are deleted, o modules are inserted, and o modules are removed.
Entity changes occur when one of the following fields of an existing chasEntityTable is modified:
o chasEntityCommunity, o chasEntityIpAddress, or o chasEntityAccessMethod.
(This does not count in chasEntityOperStatus of an existing entry.)
NOTE: The chasEntityChanges counter is incremented when ever an instance of the chasEntityChangeCounter is incremented.
What is chasEntityChangeCounter?
A per-slot Counter incremented whenever entity rows for that slot are added, deleted, or have their community/IP/access-method changed. Since the global chasEntityTable can be large, an NMS polls this per-slot counter to know exactly which slot's entity rows need re-reading instead of walking the whole table.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.1.1.1.2.4.1.2 snmpwalk -v2c -c public <target> DECHUB900-CHASSIS-MIB-V3-0::chasEntityChangeCounter
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.1.1.1.2.4.1.2.1 snmpget -v2c -c public <target> DECHUB900-CHASSIS-MIB-V3-0::chasEntityChangeCounter.1
