chasEntityChanges
Module: DECHUB900-CHASSIS-MIB-V3-0
OID (symbolic): DECHUB900-CHASSIS-MIB-V3-0::chasEntityChanges
OID (numeric): 1.3.6.1.4.1.36.2.18.11.1.1.1.2.1
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: A counter which is incremented whenever entity table entries are added or deleted, and when one of the following fields of an existing chasEntityTable is modified:
o chasEntityCommunity, o chasEntityIpAddress, or o chasEntityAccessMethod
Entity changes occur when the IP address or one of the community strings of a device is changed. This counter is also incremented:
o when modules are inserted, o when modules are removed, and o when chasEntityCommunity, chasEntityIpAddress, or chasEntityAccessMethod of an existing entry changes.
(This does not count in chasEntityOperStatus of an existing entry.)
What is chasEntityChanges?
A Counter incremented whenever entity table rows are added/deleted or when an entry's community string, IP address, or access method changes (e.g. on module insertion/removal). Polling this single counter tells an NMS whether it's worth re-reading the larger chasEntityTable.
