Transmit Discards
Total Discards - The sum of single collision frames discarded,
multiple collision frames discarded, and excessive frames dis-
carded.
Single Collision Frames - A count of the number of successfully
transmitted frames on a particular interface for which transmis-
sion is inhibited by exactly one collision.
Multiple Collision Frames - A count of the number of success-
fully transmitted frames on a particular interface for which trans-
mission is inhibited by more than one collision.
Excessive Collisions - A count of frames for which transmission
on a particular interface fails due to excessive collisions.
Port Membership - The number of frames discarded on egress
for this port due to egress filtering being enabled.
VLAN Viable Discards - The number of frames discarded on
this port when a lookup on a particular VLAN occurs while that
