Description: Number of bits of VPI supported.
What is lportAtmVpiBits?
This sets how many bits of the VPI field this logical port's ATM engine allocates, which caps the maximum VPI value (2^bits - 1) that circuits on this port can be configured with. An admin sizes this to the physical ATM interface type -- e.g. 4 bits for a DXI/HSSI or DS3/E3 port, up to 12 bits for an STM-1/STS-3c port -- and a mismatch will make circuits with VPI values outside that range fail to provision. For example, setting lportAtmVpiBits to 4 limits VPI to the 0-15 range typical of an ATM DXI/HSSI port, while an STM-1/STS-3c IWU port needs it set higher to admit VPI values up to 4095.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.215 snmpwalk -v2c -c public <target> CASCADE-MIB::lportAtmVpiBits
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.5.1.1.215.1 snmpget -v2c -c public <target> CASCADE-MIB::lportAtmVpiBits.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.5.1.1.215.1 i <value>
