Table 149: Link Services show interfaces Output Fields (continued)
Level of OutputField DescriptionField Name
detail extensive none• MRRU exceeded—Number of reassembled packets exceeding the MRRU. This
counter is not implemented in this release.
• Fragment timeout—Drop timer expired while a fragment sequence number
was outstanding. Occurs only if the drop timer is enabled. This timeout can
occur if the differential delay across the links in a bundle exceeds the
drop-timer setting, or if a multilink packet is lost in transit while the drop timer
is enabled.
• Missing sequence number—Gap detected in the sequence numbers of
fragments on a bundle.
• Out-of-order sequence number—Two frames with out-of-order sequence
numbers within a single link. This event indicates that an individual link within
a bundle reordered traffic, making the multilink interface unable to correctly
process the resulting stream.
• Out-of-range sequence number—Frame with an out-of-range sequence
number. These events can occur when a large amount of
multilink-encapsulated traffic is lost or the multilink peer is reset, so that a
large jump in sequence numbers results. A small number of these events can
occur when the far end of a bundle is taken down or brought up.
• Packet data buffer overflow—Packet buffer memory full. This overflow can
occur when the aggregate data rate exceeds the physical link services IQ
interface capacity.
• Fragment data buffer overflow—Fragment buffer memory full. This overflow
can occur when excessive differential delay is experienced across the links
within a single bundle, or when the aggregate data rate exceeds the physical
link services IQ capacity.

detail extensiveInformation about bundle errors.
• Packet drops—Number and byte count of output packets that were dropped,
rather than being encapsulated and sent out of the router as fragments.
• Fragment drops—Number and byte count of input fragments that were
dropped, rather than being reassembled and handled by the router as packets.
• MRRU exceeded—Number of reassembled packets exceeding the MRRU.
• Exception events—Number of exceptional events encountered other than
MRRU exceeded errors. These events are categorized under the physical
interface: Frame exceptions, Buffering exceptions, and Fragment exceptions.
Exception events do not necessarily indicate that the multilink interface is
not operating properly. Individual link failures can produce exceptional events.
Bundle errors
detail extensiveInformation about fragments and packets received and sent by the router. All
references to traffic direction (input or output) are defined with respect to the
router. Input fragments received by the router are assembled into input packets;
output packets are segmented into output fragments for transmission out of
the router.
• Bundle—Information about bundles.
• Link—Information about links used in the multilink operation.
