You can select or change the following values:
Slot The 16 base ports are associated with slot 0. A feature module in Slot 1 or
Slot 2 have ports 1-8 associated with them.
Port Indicates the port number. Ports are identified by a slot and port number.
The slot and port number are separated by a period (.). The base set of
ports are considered to be on slot 0. The feature slots are Slot 1 and Slot 2.
For each slot, the ports are numbered 1 to 8. Since there are 16 base
ports, each 8275-416 has ports 0.1 to 0.16. Ports on a feature module
located in Slot 1 are numbered 1.1 to 1.8, and ports on a feature module in
Slot 2 are numbered 2.1. to 2.8.
Admin Mode
This value indicates if the port is Enabled or Disabled. The default for all
ports is Enabled. At start-up, each port is reset and the spanning tree state
reported is Disabled until the Link is Up. The 8275-416 ensures that the
station is at the correct speed and duplex setting, turns on the port LED
that indicates Link is Up. Once the Link is up, the port transmits and
receives frames and participates in the spanning tree protocol as defined by
the spanning tree configuration.
Physical Mode
The value of Auto (autodetect) is valid only for 10/100BASE-TX ports.
Link Trap
This value can be Enabled or Disabled. It allows you to enable traps by
port.
