portCamShow
Displays port-based filter CAM utilization.
SYNOPSIS portcamshow [slot/]port
DESCRIPTION Use this command to display the current filter Content-Addressable Memory (CAM) utilization of a
specified port.
The command displays the following information:
SID used
Total number of CAM entries used by this port. Note that each CAM entry, either
source ID (SID) or destination ID (DID) CAM, can be shared among a certain
number of ports, depending on the ASIC.
DID used
Total number of CAM entries used by this port. Note that each CAM entry (either
SID or DID CAM) can be shared among a certain number of ports, depending on
the ASIC.
SID entries
All existing source ID entries within the CAM for this port. Note that each CAM
entry (either SID or DID CAM) can be shared among a certain number of ports,
depending on the ASIC.
DID entries
All existing destination ID entries within the CAM for this port. Note that each CAM
entry (either SID or DID CAM) can be among a certain number of ports,
depending on the ASIC.
SID free
The total number of free SID CAM entries available for use by this port.
DID free
The total number of free DID CAM entries available for use by this port.
NOTES This command cannot be executed on a logical port.
Ports that support shared areas are divided into two ports: primary and secondary ports. Primary and
secondary ports share the same area. Port CAM entries displayed on the primary ports also consist of all
the secondary port SIDs and DIDs as well, when both the ports are F_Ports. This is because the primary
port acts as a proxy for the CAM entries of the secondary port, in this case using redirect filters.
The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
This command is not supported on FCoE ports.
This command cannot be executed on a logical port.
OPERANDS This command has the following operands:
slot
For bladed systems only, specifies the slot number of the port to display, followed
by a slash (/).
port
Specifies the port number to display, relative to its slot for bladed systems. Use
switchShow to list valid ports. This operand is required.
