Fabric OS Command Reference 881
53-1003131-01
portRouteShow
2
portRouteShow
Displays routing tables for the specified port.
SYNOPSIS portrouteshow [slot/]port
DESCRIPTION Use this command to display the port address ID for a specified port and the contents of the following
port routing tables:
External unicast routing table
Displays how the specified port forwards unicast frames to remote domains in the
following format: domain_number: ports_bitmap
domain_number
The remote domain ID to which frames are ultimately routed.
ports_bitmap
The port number on the ASIC pair to which frames for the domain ID forward in
bitmap hex format; for example, 0x0100 indicates port 8 on the ASIC pair. The
arrangement of ports on an ASIC pair is specific to the system type. For any active
port, this table contains at least one entry, which routes unicast frames destined to
the embedded port (value 0x10000) of the local domain.
Internal unicast routing table
Displays how the specified port forwards unicast frames to a locally attached
NX_Port in the following format: area_number: ports_bitmap
area_number
The area number of a device (or set of looped devices) attached to the local
switch.
ports_bitmap
The format of ports_bitmap is the same as the one used in the external unicast
routing table.
Broadcast routing table
Displays how the specified port forwards broadcast frames. There is one bit map
entry in this table, similar to the bit maps in the other tables; however, this table
typically has only Bit 16 set (value 0x10000), indicating this port always routes
broadcast frames to the embedded port, for handling by the firmware.
NOTES 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.
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 number of the port to display, relative to its slot for bladed systems.
