Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::nodeRefclockActiveCGUMode
OID (numeric): 1.3.6.1.4.1.277.1.3.80
Node type: OBJECT-TYPE

Access: read-only
Description: The clock mode of the current master CGU board.
What is nodeRefclockActiveCGUMode?
This reports the operating mode of the currently active master CGU: normally sync-to-reference-clock(2) when locked to a valid timing source, but degrading to holdover(3) or extended-holdover(4) if the reference is lost, or free-running(1) if it never had one. Seeing nodeRefclockActiveCGUMode report extended-holdover(4) rather than sync-to-reference-clock(2) tells an admin the switch has been running without a valid external timing reference for an extended period and clock drift is a growing risk.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.3.80 snmpwalk -v2c -c public <target> CASCADE-MIB::nodeRefclockActiveCGUMode
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.3.80.1 snmpget -v2c -c public <target> CASCADE-MIB::nodeRefclockActiveCGUMode.1
