lportAtmVciBits

Module: CASCADE-MIB

OID (symbolic): CASCADE-MIB::lportAtmVciBits

OID (numeric): 1.3.6.1.4.1.277.1.5.1.1.216

Description: Number of bits of VCI supported.

What is lportAtmVciBits?

This sets how many bits of the VCI field this logical port's ATM hardware recognizes, defining the maximum VCI value (2^bits - 1) that circuits on this port can use. An admin sizes this to the physical ATM interface's addressing capacity; too few bits and a legitimate VCI value above the range gets rejected when a circuit is created on this port. For instance, on an ATM UNI DS3/E3 port where VCI ranges 0-255 this would be set to 8, whereas a larger STM-1/STS-3c trunk supporting VCI values up to 4095 needs 12.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.216
snmpwalk -v2c -c public <target> CASCADE-MIB::lportAtmVciBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.216.1
snmpget -v2c -c public <target> CASCADE-MIB::lportAtmVciBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.216.1 i <value>
