Module: CROUTE-MIB

OID (symbolic): CROUTE-MIB::ipAccessControlSrcMask

OID (numeric): 1.3.6.1.4.1.81.31.1.8.1.3

Node type: OBJECT-TYPE

Description: The MASK address of the source address.

What is ipAccessControlSrcMask?

This read-write IpAddress object sets the subnet mask applied to ipAccessControlSrcAddr, determining whether the rule matches a single host or an entire network range. An admin widens or narrows this mask to control how broadly the source-address match applies. For example, setting the mask to 255.255.255.0 alongside a network address matches an entire /24 subnet rather than just one host.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.1.8.1.3
snmpwalk -v2c -c public <target> CROUTE-MIB::ipAccessControlSrcMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.1.8.1.3.1
snmpget -v2c -c public <target> CROUTE-MIB::ipAccessControlSrcMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.81.31.1.8.1.3.1 a <value>
