vlanCMMIPv6SubnetRoutePrefixLen1

Module: CME-MIB

OID (symbolic): CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen1

OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.92

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: This object sets the IPv6 address prefix length of the subnet route 1 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 vlanCMMIPv6SubnetRoutePrefixLen1?

This writable object sets the prefix length for the first static IPv6 subnet route (vlanCMMIPv6SubnetRoute1) on a VLAN entry, and like the VLAN's main IPv6 address is tied to the Ethernet interface for the default VLAN entry. It defines exactly how large the routed subnet reachable via route 1 is, so an admin must match it to how the destination network is actually subnetted. Pairing fd00:20:: with a prefix length of 64 here would describe a standard /64 route to that subnet.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.92
snmpwalk -v2c -c public <target> CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen1

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.92.1
snmpget -v2c -c public <target> CME-MIB::vlanCMMIPv6SubnetRoutePrefixLen1.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.2.3.51.2.4.9.1.20.20.1.92.1 i <value>
