Module: AC-BOARD-MIB
OID (symbolic): AC-BOARD-MIB::vCMask
OID (numeric): 1.3.6.1.4.1.5003.9.10.1.1.7.2
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: VC masking bits used for address resolution
What is vCMask?
This large integer mask determines which bits of an ATM Virtual Circuit identifier participate in address resolution. Engineers set it to define VC space allocation across multiple boards on the UTOPIA interface. A value of 16711935 (0x00FFFFFF) reserves the lower 24 bits for circuit addressing.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.1.1.7.2 snmpwalk -v2c -c public <target> AC-BOARD-MIB::vCMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5003.9.10.1.1.7.2.1 snmpget -v2c -c public <target> AC-BOARD-MIB::vCMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5003.9.10.1.1.7.2.1 i <value>
