vlanCMMIPv6SubnetRoutePrefixLen3

Module: CME-MIB

OID (symbolic): CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen3

OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.96

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object sets the IPv6 address prefix length of the subnet route 3 for this VLAN entry.

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

For all other VLAN entries, this object may be set to any IP address except the IP address of the ethernet interface.

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 vlanCMMIPv6SubnetRoutePrefixLen3?

This writable object supplies the prefix length for the third static IPv6 subnet route (vlanCMMIPv6SubnetRoute3). Since routes 1-3 are independently sized subnets, this value must be set to match however the fd00:40:: destination is actually subnetted. An admin routing to fd00:40:: in route 3 would commonly set this prefix length to 64.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.96
snmpwalk -v2c -c public <target> CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen3

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.96.1
snmpget -v2c -c public <target> CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen3.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.96.1 i <value>
