Module: IPV6-MIB

OID (symbolic): IPV6-MIB::ipv6IfIdentifierLength

Description: The length of the Interface Identifier in bits.

This object is obsolete. It can be derived from the length of IP-MIB::ipv6InterfaceIdentifier; Interface Identifiers that are not an even number of octets are not supported.

What is ipv6IfIdentifierLength?

Reported the length, in bits, of the interface identifier (0-64). Obsolete — it can now be derived from the length of IP-MIB::ipv6InterfaceIdentifier, since only whole-octet identifier lengths are supported.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.55.1.5.1.7
snmpwalk -v2c -c public <target> IPV6-MIB::ipv6IfIdentifierLength

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.55.1.5.1.7.1
snmpget -v2c -c public <target> IPV6-MIB::ipv6IfIdentifierLength.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.55.1.5.1.7.1 i <value>
