ipRouteMask

Module: LANART-AGENT

OID (symbolic): LANART-AGENT::ipRouteMask

OID (numeric): 1.3.6.1.2.1.4.21.1.11

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 ipRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the ipRouteMask by determining whether the value of the correspondent ipRouteDest 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 ipRouteDest 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 routing subsystems implicitly use this mechanism.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.4.21.1.11
snmpwalk -v2c -c public <target> LANART-AGENT::ipRouteMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.4.21.1.11.1
snmpget -v2c -c public <target> LANART-AGENT::ipRouteMask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.4.21.1.11.1 a <value>
