rlIpv6PathMtuEntryMtu
Module: CISCOSB-IPv6
OID (symbolic): CISCOSB-IPv6::rlIpv6PathMtuEntryMtu
OID (numeric): 1.3.6.1.4.1.9.6.1.101.129.9.1.3
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: The MTU value that was received in packet-too-bug message for specific destination.
What is rlIpv6PathMtuEntryMtu?
This read-only value reports the MTU size that was received in a packet-too-big ICMPv6 message for a specific destination, forming that destination's path MTU entry. An admin checks this to see what maximum packet size the network path to a destination can actually support. For example, seeing an entry with an MTU of 1280 for a given destination indicates that path requires smaller packets than the local link's own MTU.
