vlanCMMIPv4SubnetRouteMask1

Module: CME-MIB

OID (symbolic): CME-MIB::vlanCMMIPv4SubnetRouteMask1

OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.52

Node type: OBJECT-TYPE

Type: IpAddress

Access: read-write

Description: This object sets the IPv4 subnet route mask 1 for this VLAN entry.

The entry with the vlanCMMIndex value of 1 (default VLAN entry) will always have this object set to 0.0.0.0.

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 vlanCMMIPv4SubnetRouteMask1?

This read-write object sets the IPv4 subnet mask for subnet route 1 on a VLAN entry, where the default VLAN entry (index 1) is always fixed at 0.0.0.0, while other VLAN entries may be set to any valid subnet mask, and the change requires vlanCMMState to be set to enable for it to take effect. An administrator configures this alongside vlanCMMIPv4SubnetRoute1 to correctly scope the extra static route added for a non-default VLAN entry. For example, an admin sets this subnet route mask to match the secondary subnet's actual size, then sets vlanCMMState to enable so the paired route and mask take effect together.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.52
snmpwalk -v2c -c public <target> CME-MIB::vlanCMMIPv4SubnetRouteMask1

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.52.1
snmpget -v2c -c public <target> CME-MIB::vlanCMMIPv4SubnetRouteMask1.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.52.1 a <value>
