ifOutErrors
For packet ‐ oriented interfaces, the number of outbound
packets that could not be transmitted because of errors.
For character ‐ oriented or fixed ‐ length interfaces, the
number of outbound transmission units that could not
be transmitted because of errors.
VLAN Discards Discarded because the packet was tagged with a VLAN
to which this port is not a member.
Filter Discards Dropped by the Content Aware Engine (user ‐ configured
filter).
Policy Discards Dropped due to policy setting. For example, due to a
user ‐ configured static entry.
Non ‐ Forwarding State Discarded because the ingress port is not in the
forwarding state.
IBP/CBP Discards Discarded because of Ingress Back Pressure (flow
control), or because the Common Buffer Pool is full (for
example, insufficient packet buffering).
OBM LP packet
discards
Number of low priority packets discarded because of
oversubscription buffer management. Oversubscription
is applicable only for packet size less than 200 bytes.
OBM HP packet
discards
Number of high priority packets discarded because of
oversubscription buffer management. Oversubscription
is applicable only for packet size less than 200 bytes.
HOL ‐ blocking Dis ‐
cards
Discarded because of the Head Of Line (HOL) blocking
mechanism. Low ‐ priority packets are placed in a sepa ‐
rate queue and can be discarded while applications or
the TCP protocol determine whether a retransmission is
necessary. HOL blocking forces transmission to stop
until the overloaded egress port buffer can receive data
again.
MMU Discards Discarded because of the Memory Management Unit.
Cell Error Discards
MMU Aging Discards
Other Discards Discarded packets not included in any category.
