Holds an index into clPortTable identifying which specific clock port should serve as the main (active) clock in this module's redundancy scheme; an admin writes a different clPortId value here to manually switch which physical clock source is driving the chassis timing.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.16.1.1.1.3
snmpwalk -v2c -c public <target> MODULES-MIB::clGroupMainClock

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.16.1.1.1.3.1
snmpget -v2c -c public <target> MODULES-MIB::clGroupMainClock.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.16.1.1.1.3.1 i <value>
