ipv6DefaultHopLimit

Module: IPV6-MIB

OID (symbolic): IPV6-MIB::ipv6DefaultHopLimit

OID (numeric): 1.3.6.1.2.1.55.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: The default value inserted into the Hop Limit field of the IPv6 header of datagrams originated at this entity, whenever a Hop Limit value is not supplied by the transport layer protocol.

This object is obsoleted by IP-MIB::ipv6IpDefaultHopLimit.

What is ipv6DefaultHopLimit?

Set the default Hop Limit (0-255, default 64) stamped into outgoing IPv6 packets when the sending application didn't specify one — the IPv6 equivalent of TTL. It's obsolete, replaced by IP-MIB::ipv6IpDefaultHopLimit, so current tooling should poll that object for this value.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.55.1.2
snmpwalk -v2c -c public <target> IPV6-MIB::ipv6DefaultHopLimit

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.55.1.2.1
snmpget -v2c -c public <target> IPV6-MIB::ipv6DefaultHopLimit.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.2.1.55.1.2.1 i <value>
