jnxPMCurDiffGroupDelay
Module: JUNIPER-IFOPTICS-MIB
OID (symbolic): JUNIPER-IFOPTICS-MIB::jnxPMCurDiffGroupDelay
OID (numeric): 1.3.6.1.4.1.2636.3.71.1.2.1.1.2
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: Differential group delay
What is jnxPMCurDiffGroupDelay?
The current differential group delay, in picoseconds, a coherent-optics metric measuring the timing spread between the two polarization modes of the signal caused by polarization mode dispersion in the fiber. Admins watch this on long fiber runs since excessive differential group delay degrades a coherent receiver's ability to properly decode the signal.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2636.3.71.1.2.1.1.2 snmpwalk -v2c -c public <target> JUNIPER-IFOPTICS-MIB::jnxPMCurDiffGroupDelay
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2636.3.71.1.2.1.1.2.1 snmpget -v2c -c public <target> JUNIPER-IFOPTICS-MIB::jnxPMCurDiffGroupDelay.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> jnxPMCurDiffGroupDelay.1
