Displaying Token Ring Switch Statistics
In Release 3.4 and later, you can display statistics for the new generation of Token Ring
modules known as “Bigfoot” (e.g., TSM-CD-16W, TSX-CD-16W, and TSX-C-32W). For exam-
ple, if you want to display the switch statistics for a Token Ring port on Port 1 on Slot 4,
enter:
swch 4/1
at the system prompt. Press
r
and then press
<Enter>
at the prompt. Something like the follow-
ing displays:
n={e,s,2,3},quit,save,? (?) : r

Note that the default option is now
r
. If you press
<Enter>
, the switch statistics will be redis-
played.
The fields displayed by the
r
option of the
swch
command for Token Ring are described
below.
The first group of statistics are the numbers of bytes transmitted and received. These are
useful in working out bandwidth usage by the port. Bad octets are important to count in the
total octets count as they consume bandwidth at the expense of useful traffic. To ignore them
would lead to mysterious loss of bandwidth in any calculations performed.
Rx MAC Good Bytes
. The total number of bytes received in good Media Access Control (MAC)
packets. (MAC packets are used for management of the Token Ring network.)
Rx LLC Good Bytes
. The total number of bytes received in good Logical Link Control (LLC)
packets. (LLC packets are used to transfer data.)
Rx Total MAC Packets
. The total number of bytes received in MAC packets.
Rx Total LLC Packets
. The total number of bytes received in LLC packets.
Rx MAC Errored Bytes
. The total number of bytes received in bad MAC packets.
