cmDHCPNetMask
Module: COPPER-MOUNTAIN-NETWORKS-DSL-MIB
OID (symbolic): COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmDHCPNetMask
OID (numeric): 1.3.6.1.4.1.1996.20.19.1.1.4
Node type: OBJECT-TYPE
Type: IpAddress
Access: read-write
Description: This is the NetMask that will be sent to the CPE when a DHCP request is received over the DSL link.
Default: 0.0.0.0
What is cmDHCPNetMask?
This read-write IpAddress, defaulting to 0.0.0.0, is the subnet mask sent to the CPE alongside the DHCP-assigned address on this DSL link. An admin sets it to ensure the CPE gets the correctly sized subnet for that line. For example, an admin sets cmDHCPNetMask to 255.255.255.0 to match the /24 subnet configured via cmDHCPIpAddress.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1996.20.19.1.1.4 snmpwalk -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmDHCPNetMask
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1996.20.19.1.1.4.1 snmpget -v2c -c public <target> COPPER-MOUNTAIN-NETWORKS-DSL-MIB::cmDHCPNetMask.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.1996.20.19.1.1.4.1 a <value>
