cwdsiMobilityGrpTunnelMtu
Module: CISCO-WDS-INFO-MIB
OID (symbolic): CISCO-WDS-INFO-MIB::cwdsiMobilityGrpTunnelMtu
OID (numeric): 1.3.6.1.4.1.9.9.509.1.6.9.1.4
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-only
Description: This object specifies the maximum transmission unit of IP packet for the Mobility tunnel.
What is cwdsiMobilityGrpTunnelMtu?
This object reports the maximum transmission unit, in bytes, configured for IP packets traversing the mobility tunnel. Administrators care about this because a mismatched or too-small MTU on the mGRE tunnel can cause fragmentation or dropped packets for roaming mobile-node traffic. For example, if mobile nodes experience intermittent packet loss for larger payloads after roaming, comparing cwdsiMobilityGrpTunnelMtu against the path MTU of the underlying network can reveal a tunnel MTU mismatch.
