Description: VPI value in the ATM cell header: ATM DXI with HSSI IOP VPI (4 lsb bit) range: 0 - 15 ATM UNI DS3/E3 IOP VPI (4 lsb bit) range: 0 - 15 T1 ATM 4 lsb range 0-15 ATM-IWU STM-1/STS-3c VPI (<=12 lsb bit) range: 0-4095

What is cktAtmVPI?

This is the actual VPI value configured for this ATM circuit's cell header, whose valid range depends entirely on which physical ATM interface type carries it -- as few as 4 bits, 0-15, on DXI/HSSI and DS3/E3 ports, up to 12 bits, 0-4095, on STM-1/STS-3c interfaces. An admin provisioning a circuit must set this within the range appropriate to the actual port hardware, since a VPI value valid on an STM-1 card would be rejected on a DXI/HSSI port. For example, configuring cktAtmVPI to 200 would fail on an ATM DXI/HSSI port limited to 0-15 but would be perfectly valid on an ATM-IWU STM-1/STS-3c card supporting up to 4095.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.73
snmpwalk -v2c -c public <target> CASCADE-MIB::cktAtmVPI

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.1.6.1.1.73.1
snmpget -v2c -c public <target> CASCADE-MIB::cktAtmVPI.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.277.1.6.1.1.73.1 i <value>
