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:
The execution of this command is subject to Admin Domain restrictions that may be in place.
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.
Examples To display the routing tables for a port:
switch:user> portrouteshow 4/15
port address ID: 0x02bf00
external unicast routing table:
1: 0x4 (vc=3)
2: 0x10000 (vc=0)
internal unicast routing table:
60: 0x8000 (vc=2)
63: 0x1000 (vc=5)
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
is the remote domain ID to which frames are
ultimately routed.
ports_bitmap contains 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
arrangements 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 forward unicast frames to locally
attache Nx_Ports in the following format:
area_number: ports_bitmap
area_number
represents the area number of a device (or set of
looped devices) attached to the local switch. 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.
