Viewing Ring-level Information 3-19
Ring Map
If the inserted station is connected to another hub (via the monitored hub’s
Ring-in/Ring-out ports), the board and port are unknown and will display as
zeroes (0,0).
The station’s physical drop is an administratively assigned string that you can use
to identify a station’s physical location. If assigned, the drop will appear as a
subvector in certain Token Ring MAC frames (such as a new active monitor
frame, report error frame, or the report station address frame used in the neighbor
notification process). A physical drop consists of up to four alphanumeric
characters; to set one, see
Setting a Station Drop , page 3-9 .
Name – This label displays the name administratively assigned to each station, if
one has been assigned. To assign one, see Setting a Station Name , page 3-8 .
If a station does not have an administratively assigned name, <none> will display
in the label.
MAC Address – This is the default label; it displays each station’s six byte MAC
address in Canonical format (reverse bit order).
Vendor/MAC Address – This label displays the vendor of the monitored station,
as determined by the first three bytes of its MAC address; the remainder of the
MAC address is also displayed.
To change the label format of a station:
1. Click on at the top of the Ring Map window.
2. Drag down to Label by, and then right to select a label option: Board, Port,
Drop; Name; MAC Address; or Vendor + MAC Address.
The Ring Map window will refresh, and the station labels will reflect the selected
display option.
