drStaticCidrMask
Module: CROUTE-MIB
OID (symbolic): CROUTE-MIB::drStaticCidrMask
OID (numeric): 1.3.6.1.4.1.81.31.7.1.1.3
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-only
Description: Equivalent to ipCidrRouteMask. Indicate the mask to be logical-ANDed with the destination address before being compared to the value in the drStaticCidrDest field. For those systems that do not support arbitrary subnet masks, an agent constructs the value of the drStaticCidrMask by reference to the IP Ad- dress 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 drStaticCidrDest object is not equal to drStaticCidr- Dest.
What is drStaticCidrMask?
This object holds the subnet mask for a static CIDR route, equivalent to ipCidrRouteMask, used to determine how much of the destination address must match before the route applies. Administrators set this precisely because an incorrect mask can cause the route to match too broadly or too narrowly, misdirecting traffic. For example, pairing drStaticCidrMask 255.255.0.0 with a /16 destination network correctly scopes the static route to that entire subnet.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.81.31.7.1.1.3 snmpwalk -v2c -c public <target> CROUTE-MIB::drStaticCidrMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.81.31.7.1.1.3.1 snmpget -v2c -c public <target> CROUTE-MIB::drStaticCidrMask.1
