Oper. Indicates the current Operational Status of the port. The port will be Active (Active) or
Inactive (Inactv). If the port is Active, then the port can pass data and has a good physical
connection. If it is Inactive, then it may not have a good physical connection and it is not
capable of passing data at this time.
Spn Tr. The port’s current state as defined by the Spanning Tree Protocol. The possible Span-
ning Tree States are: Disabled, Blocking, Listening, Learning, and Forwarding. This state
controls the action a port takes when it receives and transmits a frame. For ports which are
Administratively disabled or Operationally Inactive, this state will be Disabled (Disabl), mean-
ing the Spanning Tree algorithm is not active on this port. If the state is Blocking, then only
BPDUs will be transmitted and received. If the state is Forwarding, then both data and BPDU
frames will be transmitted and received. This Spanning Tree Protocol state is not applicable to
virtual router ports and will read N/A for those ports.
Mode. The Bridge Mode currently in use on this port. This mode is chosen during the port
configuration phase of the crgp command, through the addvp command, or through the
modvp command. It is not applicable to virtual router ports and will read N/A for those ports.
Possible values are:
•
Bridged Spanning Tree Bridge.
•
AutoSw Auto Switch.
•
Optimzd Optimized Device Switching.
See page 19-29 for a description of these bridge modes.
