mpBundleStatusMediumPktMaxSize
Module: XEDIA-PPP-MP-MIB
OID (symbolic): XEDIA-PPP-MP-MIB::mpBundleStatusMediumPktMaxSize
OID (numeric): 1.3.6.1.4.1.838.3.21.1.1.1.1.9
Node type: OBJECT-TYPE

Access: read-only
Description: The maximum size in bytes of a Medium PPP packet. This value specifies the threshold at which Multilink fragmentation is applied to transmitted packets, i.e. packets smaller than this size will be encapsulated in a single Multilink Protocol fragment and sent on a single link, packets larger than this size will be fragmented over all links in the bundle.
This value starts at mpBundleConfigMediumPktMaxSize and is adjusted downwards according to the peer's MRRU and each of the peer's link's MRUs.
Medium PPP packets are defined to be those which will be encapsulated in a single Multilink Protocol Fragment and sent on each link in the Bundle in a round-robin fashion.
Packets larger than this threshold are considered Large PPP packets. Large PPP packets will be fragmented into multiple Multilink Protocol Fragments and sent across all links in the bundle.
Setting this value to its maximum (65535) will prevent fragmentation at the MP layer of outgoing PPP packets, i.e. it will cause all outgoing PPP packets to be considered either Small or Medium sized PPP packets.
Note that this parameter only applies to outgoing PPP packets sent by this system. Reassembly of incoming packets is unaffected by this value.
What is mpBundleStatusMediumPktMaxSize?
The current threshold, in bytes, below which outgoing PPP packets are sent whole (round-robin across the bundle's links) rather than fragmented across all links; it starts at mpBundleConfigMediumPktMaxSize (default 64) and is adjusted down based on the peer's negotiated MRRU and link MRUs — setting it to 65535 disables MP-layer fragmentation of outgoing packets entirely.
