chasConnChanges

Module: DECHUB900-CHASSIS-MIB-V3-0

OID (symbolic): DECHUB900-CHASSIS-MIB-V3-0::chasConnChanges

OID (numeric): 1.3.6.1.4.1.36.2.18.11.1.1.1.5.2

Node type: OBJECT-TYPE

Type: Counter

Access: read-only

Description: The number of physical changes that have occurred in the chassis backplane configuration since the agent was warm/cold started. Specifically, this object is incremented:

1) whenever chasConnEntryStatus for any object becomes 'valid', 2) whenever chasConnEntryStatus transitions from 'valid' to any other state, and 3) whenever the chasConnSegment or chasConnPort of a 'valid' chasConnEntry is modified.

What is chasConnChanges?

A Counter incremented whenever a backplane connection (chasConnTable entry) becomes valid, leaves the valid state, or has its segment/port modified — which happens on module insertion, removal, or manual reconfiguration. Admins poll this to know when it's worth re-reading the connection table for topology changes.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.36.2.18.11.1.1.1.5.2
snmpwalk -v2c -c public <target> DECHUB900-CHASSIS-MIB-V3-0::chasConnChanges

Get a specific instance (index 1):
