portRouteShow
Displays routing tables for the specified port.
Synopsis portrouteshow [slotnumber/]portnumber
Description Use this command to display the port address ID 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 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.
Note The execution of this command is subject to Admin Domain restrictions that may be in place. Refer
to chapter 1, "Understanding Admin Domain Restrictions" and Appendix A, "Command Availability"
for details.
Operands This command has the following operands:
slotnumber For bladed systems only, specifies the slot number of the port to display,
followed by a slash (/).
portnumber Specifies the number of the port to display, relative to its slot for bladed
systems. Use switchShow to display a list of valid ports.
