Physical and Logical Port Trace Display (stpni_debugport)
This is a combination of the Logical and Physical port display. See “Logical Ports (stpni_debugLport)” on
page 4-19 and “Physical Port (stpni_debugPport)” on page 4-20 for more information.
Socket Handler Traces
These traces include Global data, warning, and event traces. They are implemented on the CMM and NI.
These traces are listed below and described in the following subsections:
stpNISock_globals
This trace handles the Socket Handler. Its components are listed below:
• sockGlobal_protThreshold: This parameter is the maximum number of message that can be
processed consecutively on the Protocol Manager channel (CMM/NI STP channel).
• sockGlobal_maxmsgprot: This counter is the maximum number of message (counter) processed
consecutively on the Protocol Manager channel (CMM/NI STP channel).
• sockGlobal_evtThreshold: This parameter is the maximum number of message that can be processed
consecutively on the Message Event Manager channel (inter-NI STP channel).
Portid Global port identifier (0x0190xxxx indicates that it is a logical port, and
0x0001 indicates that it is logical port 1).
NTag Number of tags (802.1q) attached to that port. This field should always
be 0 when the port is FIXED or MOBILE.
Vector Bitmap of the local ports that belong to the aggregator (logical port). In
the example local port 1 and 2 belong to the aggregator (MSB= port 31
and LSB = port 0).
lpid Local port identifier of the logical port to which to physical port is
bounded. In the current display, it indicates that physical ports 1 and 2
are bounded to logical port 1 (0x81). Within the Spanning Tree NI, a
logical port type is identified by setting bit 7 to 1 in the local port (1
byte field). This field is not significant if the port is not aggregable (see
the interpretation of the sta field in the display).
Prim Not significant for the physical port.
Bw Bandwidth as received on Link up from the ENI driver.
Duplex Duplex mode as received from ENI driver on Link Up.
stpNISock_globals Global variables.
stpNISock_warningprint Warning trace.
stpNISock_totraceprint Time-out trace.
stpNISock_traceprint Event trace.
stpNISock_intraceprint Inter-NI trace.
stpNISock_boardupprint Boards seen alive by the Socket Handler.
stpNISock_printon Activates STP Socket Handler printf.
stpNISock_printoff Deactivates STP Socket Handler printf.
