cDhcpv4ServerClientSubnetMask

Module: CISCO-IETF-DHCP-SERVER-MIB

OID (symbolic): CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerClientSubnetMask

OID (numeric): 1.3.6.1.4.1.9.10.102.1.4.4.1.2

Node type: OBJECT-TYPE

Type: InetAddressPrefixLength

Access: read-only

What is cDhcpv4ServerClientSubnetMask?

Reports the subnet mask (DHCP option 1) that was provided to the client assigned this address; the resulting subnet must correspond to a configured subnet on the server.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.4.4.1.2
snmpwalk -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerClientSubnetMask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.102.1.4.4.1.2.1
snmpget -v2c -c public <target> CISCO-IETF-DHCP-SERVER-MIB::cDhcpv4ServerClientSubnetMask.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> cDhcpv4ServerClientSubnetMask.1
