7.4.2.3. Port Type Information

Ports contain data that describe their types and the properties of the cables connected to them. This includes physical information as well as metadata about the port/cable.

Ports have one of the following types:

Port Type

Description

Disconnected

Part of design but physically unused

QSFP

Standard cable port

Fixed

Hardwired unchangeable port

Variable

Hardwired changeable port

7.4.2.3.1. Cable Information

A description of cable info is shown in the table below. The bold entries are most useful for diagnostics, while the remaining entries may aid in debugging. The amount of information shown, that is, the number of fields, can be controlled by a command line option to the tools.

Note

Different output levels may show the information with slightly altered labels.

7.4.2.3.2. Port and Cable Verification Tools

In addition to opareport, several lower-level tools are useful for verifying port information and settings. These tools also allow you to view the properties for a cable in a link. These tools include:

  • opaportinfo

  • opainfo

  • opasaquery

  • opasmaquery

In some cases, the tools overlap with each other.

For additional details on each tool, refer to the CN5000 Commands Guide.

opasaquery allows you to query the Fabric Manager for its internal information. opaportinfo, opainfo, and opasmaquery can be used to query a port directly. opainfo provides information about local ports, whereas the other tools provide information about any port in the fabric.

For example:

  • opainfo -d4: Provides basic port information along with detailed cable information for local port

  • opaportinfo -l2: Provides port info for port with LID 2

  • opasmaquery -o portinfo: Provides local port information

  • opasmaquery -o cableinfo -d4: Provides local port cable information in detail

  • opasaquery -o portinfo: Provides port information for all ports in fabric

  • opasaquery -o cableinfo: Provides cable info

Note

Because opareport shows port names instead of LIDs, it may be more useful than using opasaquery.
