lportTrkUtil

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::lportTrkUtil

OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.39

Node type: OBJECT-TYPE

Type: INTEGER

Description: An estimate of the real utilization of the trunk bandwidth in terms of a percentage of the configured trunk bandwidth.

What is lportTrkUtil?

This tracks the estimated real-world utilization of the trunk, expressed as a percentage of lportDataRate, reflecting actual traffic load rather than provisioned or reserved capacity. An admin watches this metric to decide when a trunk needs more bandwidth or additional backup trunks, since sustained high values here, distinct from lportTrkOverhead's fixed control overhead, indicate real congestion risk. For example, lportTrkUtil consistently reading above 85% during peak hours is a concrete trigger to plan a trunk upgrade before users start seeing lportCongestState escalate.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.39
snmpwalk -v2c -c public <target> CASCADE-MIB::lportTrkUtil

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.39.1
snmpget -v2c -c public <target> CASCADE-MIB::lportTrkUtil.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.39.1 i <value>
