Module: CASCADE-MIB
OID (symbolic): CASCADE-MIB::lportInVAvailbw

Description: Currently available Incoming virtual bandwidth.
What is lportInVAvailbw?
This reports how much inbound virtual bandwidth remains unallocated on this logical port after existing circuits' committed rates have been subtracted from the port's total capacity. An admin checks this before provisioning a new PVC to know whether there is headroom to add another circuit's CIR without oversubscribing the port. For example, if lportInVAvailbw reads 512000 on a T1 lport, roughly a third of the port's 1.544 Mbps capacity is still free for new incoming circuits.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.218 snmpwalk -v2c -c public <target> CASCADE-MIB::lportInVAvailbw
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.218.1 snmpget -v2c -c public <target> CASCADE-MIB::lportInVAvailbw.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> lportInVAvailbw.1
