Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportIfIndex
OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.1
Node type: OBJECT-TYPE

Description: The ifIndex value of the corresponding ifEntry.
What is lportIfIndex?
This gives the standard MIB-II ifIndex value that corresponds to this logical port's entry in the ifTable. This is the bridge between this switch's proprietary Cascade logical-port model and standard interface-layer MIBs, so any generic SNMP tool that only understands ifTable-based statistics needs this value to correctly match up traffic counters and status for this specific logical port. A monitoring system pulling standard ifInOctets/ifOutOctets for interface index 42 would use this object to confirm that index 42 corresponds to this exact Cascade logical port, not a different one.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.1 snmpwalk -v2c -c public <target> CASCADE-MIB::lportIfIndex
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.1.1 snmpget -v2c -c public <target> CASCADE-MIB::lportIfIndex.1
