portInputCdv
Module: Fore-Switch-MIB
OID (symbolic): Fore-Switch-MIB::portInputCdv
OID (numeric): 1.3.6.1.4.1.326.2.2.2.1.2.2.1.49
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description:
The current value of Cell Delay Variation attributed to the input side of this port, which can be either a user specified value or the system default, as determined by the setting of portInputCdvMode.
What is portInputCdv?
This OID holds a number measuring cell delay variation on a port's incoming traffic—essentially jitter in timing between data arrivals. It can be set manually or use the device's default value based on configuration. Network engineers monitor or adjust this to ensure voice and video traffic meets quality requirements, since excessive jitter degrades real-time communication.
