a3IPaddrConfigNetMask
Module: A3COM-IPEXTNS-R5-MIB
OID (symbolic): A3COM-IPEXTNS-R5-MIB::a3IPaddrConfigNetMask
OID (numeric): 1.3.6.1.4.1.43.2.6.8.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: The subnet mask associated with the IP address of this entry. The value of the mask is an IP address with all the network bits set to 1 and all the host bits set to 0.
If this is not specified, the system will select a mask based on the IP address class.
What is a3IPaddrConfigNetMask?
This OID holds the subnet mask (as an IpAddress) that defines which bits of the IP address identify the network. Network administrators set it to segment traffic into subnets; the system auto-selects a classful mask if omitted. A typical value like 255.255.255.0 indicates a /24 subnet with 254 usable host addresses.
Examples
