What is phySerIfT1clockSource?

A read-write INTEGER (0..2) selecting the clock source for this port when it is configured as a T1 interface (internal, line/network-derived, or external). The source MIB has no DESCRIPTION text for this or any other object, so this reading is inferred from the object's name, type, and position in the real MIB tree. An admin must configure exactly one end of a T1 circuit to derive clock from the line and the other to source it, or the circuit will not synchronize.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.170.1.1.1.4.2.1.7
snmpwalk -v2c -c public <target> ISOVIEW-MIB::phySerIfT1clockSource

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.170.1.1.1.4.2.1.7.1
snmpget -v2c -c public <target> ISOVIEW-MIB::phySerIfT1clockSource.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.170.1.1.1.4.2.1.7.1 i <value>
