cIpCidrRouteMask

Module: CISCO-IETF-IP-FORWARD-MIB

OID (symbolic): CISCO-IETF-IP-FORWARD-MIB::cIpCidrRouteMask

OID (numeric): 1.3.6.1.4.1.9.10.85.4.1.2

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-only

Description: Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the cIpCidrRouteDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the cIpCidrRouteMask by reference to the IP Address Class.

Any assignment (implicit or otherwise) of an instance of this object to a value x must be rejected if the bitwise logical-AND of x with the value of the corresponding instance of the cIpCidrRouteDest object is not equal to cIpCidrRouteDest.

What is cIpCidrRouteMask?

Reports the subnet mask to be logically ANDed with the destination address when matching this route, allowing the device to determine which network the route applies to.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.85.4.1.2
snmpwalk -v2c -c public <target> CISCO-IETF-IP-FORWARD-MIB::cIpCidrRouteMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.85.4.1.2.1
snmpget -v2c -c public <target> CISCO-IETF-IP-FORWARD-MIB::cIpCidrRouteMask.1
