cnsT4ClkSrcFSW

Module: CISCO-NETSYNC-MIB

OID (symbolic): CISCO-NETSYNC-MIB::cnsT4ClkSrcFSW

OID (numeric): 1.3.6.1.4.1.9.9.761.1.1.5.1.18

Node type: OBJECT-TYPE

Type: TruthValue

Access: read-only

Description: This object indicates the forced switching flag. Forced switching, as described in G.781, is used to override the currently selected synchronization source.

The 'true' value indicates the currently selected T4 clock source is a result of the forced switching. The 'false' value indicates the currently selected T4 clock source is not a result of forced switching.

What is cnsT4ClkSrcFSW?

This object indicates whether a specific T4-table candidate source is the currently forced-switch-selected source feeding external output, mirroring cnsInpSrcFSW for the T4 selection process. Cross-referencing this being true on a lower-quality candidate confirms an operator override, rather than the automatic algorithm, is currently determining what timing signal downstream equipment is receiving from this device's T4 output.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.9.761.1.1.5.1.18
snmpwalk -v2c -c public <target> CISCO-NETSYNC-MIB::cnsT4ClkSrcFSW

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.9.761.1.1.5.1.18.1
