atmPortMaxActvBits

Module: PORT-MIB

OID (symbolic): PORT-MIB::atmPortMaxActvBits

OID (numeric): 1.3.6.1.4.1.5812.3.6.1.7

Node type: OBJECT-TYPE

Type: OCTET STRING

Access: read-write

Description: Maximum active VPI/VCI bits

What is atmPortMaxActvBits?

This holds the maximum number of active VPI/VCI bits configured for the port, encoded as an octet string. It works alongside atmPortMaxTotalBits to define how the port's virtual path and virtual circuit address space is actually being used versus its theoretical maximum. An admin adjusts this when provisioning the port's ATM addressing scheme to match the number of virtual circuits actually needed.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5812.3.6.1.7
snmpwalk -v2c -c public <target> PORT-MIB::atmPortMaxActvBits

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.5812.3.6.1.7.1
snmpget -v2c -c public <target> PORT-MIB::atmPortMaxActvBits.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.5812.3.6.1.7.1 s <value>
