Description: The number of logical ports on the physical port.

What is pportNumLport?

This reports how many logical ports (channels or sub-interfaces) have been carved out of this single physical port. On Cascade switches a physical port can be channelized into multiple logical ports, such as fractional T1 bundles or several PVC-bearing sub-interfaces, so this count tells you how subdivided this specific port's bandwidth currently is. A T1 pport showing pportNumLport of 3 means three separate logical circuits are currently carved out of that one physical T1, each independently manageable.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.4
snmpwalk -v2c -c public <target> CASCADE-MIB::pportNumLport

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.4.2.1.4.1
snmpget -v2c -c public <target> CASCADE-MIB::pportNumLport.1
