ruleSourceIpMask
Module: CTATX-MIB
OID (symbolic): CTATX-MIB::ruleSourceIpMask
OID (numeric): 1.3.6.1.4.1.97.3.23.2.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: Mask to apply to the packet before comparing to ruleSourceIp.
What is ruleSourceIpMask?
This is the mask applied to a packet's source address before comparing it against ruleSourceIp. It lets a single rule match an entire source subnet rather than one exact host, giving admins flexibility in scoping filters. Setting ruleSourceIpMask to a /24 mask alongside a ruleSourceIp would make the rule match any host in that subnet.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.97.3.23.2.1.4 snmpwalk -v2c -c public <target> CTATX-MIB::ruleSourceIpMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.97.3.23.2.1.4.1 snmpget -v2c -c public <target> CTATX-MIB::ruleSourceIpMask.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ruleSourceIpMask.1
