portRouteShow
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 restrictions that may be in place. Refer to "Using Fabric
OS Commands" and "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.
