Display routing tables for a port.
Synopsis portRouteShow port
Availability All users
Description Use this command to display the port address ID and the contents of the following port routing
tables:
Operands This command has the following operand:
External unicast routing
table
Shows unicast frame routing to another switch element in the fabric.
Output format is
domain_number: ports_bitmap
where:
domain_number is the switch element number that a unicast frame
can reach from the portnumber port.
ports_bitmap contains all output ports, in bitmap hex format, that
can forward unicast frames from port number to domain number.
This table contains at least one entry for each active port:
local_switch_domain_number: 0x10000
This is for routing unicast frames designated to the embedded port of
the local switch element.
Internal unicast routing
table
Lists all ports in the local switch that a unicast frame can reach from
portnumber. Format is
destination_port: output_ports_bitmap
Because the destination_port is in the local switch,
output_ports_bitmap usually contains one bit with a bit
position number representing the destination_port number.
Multicast routing table Shows multicast frame routing to the destination multicast group.
Output format is:
mcast_group_number: (mcast_group_id) ports_bitmap
where
mcast_group_number is the multicast group number
mcast_group_id is the multicast frame destination ID
ports_bitmap is a hex bitmap of all output port numbers that can
forward a multicast frame from the portnumber to
mcast_group_id
Broadcast routing table A bitmap, containing all ports reachable by a received broadcast
frame. Bit 16 of the bitmap is always set to allow the switch element
to receive broadcast frames.
