ipMultiPathMask
Module: ACC-IP
OID (symbolic): ACC-IP::ipMultiPathMask
OID (numeric): 1.3.6.1.4.1.5.1.1.23.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the ipMultiPathDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipMultiPathMask by determining whether the value of the correspondent ipMultiPathDest field belong to a class-A, B, or C network, and then using one of: mask network 255.0.0.0 class-A 255.255.0.0 class-B 255.255.255.0 class-C If the value of the ipMultiPathDest is 0.0.0.0(a default route), then the mask value is also 0.0.0.0. It should be noted that all IP rout- ing subsystems implicitly use this mechanism.
What is ipMultiPathMask?
The ACC-IP::ipMultiPathMask OID stores an IP subnet mask that is logically ANDed with destination addresses to determine if they match this route. A network engineer configures this to define the range of IP addresses covered by a routing entry, such as 255.255.255.0 for a /24 network. For example, ipMultiPathMask = 255.255.255.0 combined with ipMultiPathDest = 10.0.1.0 means the route applies to all addresses from 10.0.1.0 to 10.0.1.255.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.5.1.1.23.1.4 snmpwalk -v2c -c public <target> ACC-IP::ipMultiPathMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.5.1.1.23.1.4.1 snmpget -v2c -c public <target> ACC-IP::ipMultiPathMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.5.1.1.23.1.4.1 a <value>
