vlanCMMIPv4Mask

Module: CME-MIB

OID (symbolic): CME-MIB::vlanCMMIPv4Mask

OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.33

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

Description: This object sets the IPv4 subnet mask for this VLAN entry.

The entry with the vlanCMMIndex value of 1 (default VLAN entry) will have this object set to the subnet mask of the ethernet interface. The subnet mask of the default VLAN entry can only change by changing the subnet mask of the ethernet interface.

For all other VLAN entries, this object may be set to any valid subnet mask.

For a change of this object to take effect, the object, vlanCMMState, must be set to enable(1) if the vlanCMMState is currently disable(0), or set to restart(2) if the vlanCMMState is currently enable(1).

What is vlanCMMIPv4Mask?

This read-write object sets the IPv4 subnet mask for a VLAN entry, where the default VLAN entry (index 1) always mirrors the chassis ethernet interface's own subnet mask and can only be changed by changing that interface's mask, while other VLAN entries may be set independently. An administrator configures this to define the correct subnet boundary for a non-default VLAN entry's own IP address. For example, an admin sets a subnet mask on a non-default VLAN entry to correctly scope that VLAN's management subnet independent of the chassis's primary interface mask.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.33
snmpwalk -v2c -c public <target> CME-MIB::vlanCMMIPv4Mask

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.33.1
snmpget -v2c -c public <target> CME-MIB::vlanCMMIPv4Mask.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.33.1 a <value>
