Cabletron Systems ELS10-26 manual

Bridge MIB

dot1dStpPortState	{dot1dStpPortEntry 3}
Integer Read-Only

The port’s current state as defined by application of the Spanning Tree Protocol. This state controls what action a port takes on reception of a frame. If the bridge has detected a port that is malfunctioning it will place that port into the broken (6) state. For ports which are disabled (see dot1dStpPortEnable), this object will have a value of disabled (1).

dot1dStpPortEnable	{dot1dStpPortEntry 4}
Integer Read-Write

The enabled/disabled status of the port.

The ELS10-26 does not change the parameter’s value when processing a SetRequest - refer to the lxsprotoBridge parameter in Cabletron’s enterprise-specific MIB for the SetRequest capabilities.

dot1dStpPortPathCost	{dot1dStpPortEntry 5}
Integer Read-Write

The contribution of this port to the path cost of paths towards the spanning tree root which include this port.

Any value from 0 to 65535 may be specified; specifying a value of 0 will cause the ELS10-26 to automatically compute the proper default value. 1

dot1dStpPortDesignatedRoot	{dot1dStpPortEntry 6}
Octet String Read-Only

The unique Bridge Identifier of the Bridge recorded as the Root in the Configuration BPDUs transmitted by the Designated Bridge for the segment to which the port is attached.

1.The proper default is the inverse of the media baud rate (e.g., 10 for FDDI, 100 for Ethernet). The effective value is always returned in the GetResponse.
