inBandBackupIpMask
Module: ACMIB
OID (symbolic): ACMIB::inBandBackupIpMask
OID (numeric): 1.3.6.1.4.1.1751.2.18.1.30
Node type: OBJECT-TYPE

Description: IP address subnet mask of the secondary in-band management IP address.
What is inBandBackupIpMask?
This read-only OID displays the 4-octet subnet mask for the backup in-band management address, typically auto-assigned by the system. Network engineers check this value to understand the reachable network scope when management must failover to the secondary path. The mask typically mirrors the primary (like 255.255.255.0) to ensure consistent routing between primary and backup management routes.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.1.30 snmpwalk -v2c -c public <target> ACMIB::inBandBackupIpMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1751.2.18.1.30.1 snmpget -v2c -c public <target> ACMIB::inBandBackupIpMask.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> inBandBackupIpMask.1
