CLI Commands: Base
Packets Transmitted Successfully
Total - The number of frames that have been transmitted by this port
to its segment.
Unicast Packets Transmitted - The total number of packets that
higher-level protocols requested be transmitted to a subnetwork-uni-
cast address, including those that were discarded or not sent.
Multicast Packets Transmitted - The total number of packets that
higher-level protocols requested be transmitted to a Multicast
address, including those that were discarded or not sent.
Broadcast Packets Transmitted - The total number of packets that
higher-level protocols requested be transmitted to the Broadcast
address, including those that were discarded or not sent.
Transmit Errors
Total Errors - The sum of Single, Multiple, and Excessive Collisions.
Tx FCS Errors - The total number of packets transmitted that had a
length (excluding framing bits, but including FCS octets) of between
64 and 1518 octets, inclusive, but had a bad Frame Check Sequence
(FCS) with an integral number of octets
Oversized - The total number of frames that exceeded the max per-
mitted frame size. This counter has a max increment rate of 815
counts per sec. at 10 Mb/s.
Underrun Errors - The total number of frames discarded because
the transmit FIFO buffer became empty during frame transmission.
Transmit Discards
Total Discards - The sum of single collision frames discarded, multi-
ple collision frames discarded, and excessive frames discarded.
Single Collision Frames - A count of the number of successfully
transmitted frames on a particular interface for which transmission is
inhibited by exactly one collision.
Multiple Collision Frames - A count of the number of successfully
transmitted frames on a particular interface for which transmission is
inhibited by more than one collision.
Excessive Collisions - A count of frames for which transmission on
a particular interface is discontinued 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 entry in the
VLAN table is being modified, or if the VLAN has not been configured.
