topologyShow
Displays the unicast fabric topology.
Synopsis topologyshow [domain]
Description Use this command to display the fabric topology, as it appears to the local switch, including:
• A list of all domains that are part of the fabric, and to each of those domains, all possible paths from
the local switch.
• For each path cost, the associated output port on the local switch, the path cost, the number of hops
from the local switch to the destination switch and a summary of all ports are routed through that
path.
The display contains the following fields:
Local Domain ID Domain number of local switch.
Local Translate Domain x owned by port
Port number associated with the local translate domain x.
Domain Domain number of destination switch.
Metric Cost of reaching destination domain.
Name The name of the destination switch.
Path Count The number of currently active paths to the destination domain.
Hops The maximum number of hops to reach destination domain.
Out Port Port to which incoming frame are forwarded to reach the destination domain.
In Ports Input ports that use the corresponding out port to reach the destination domain.
This is the same information provided by portRouteShow and uRouteShow but
in a different format.
Total Bandwidth The maximum bandwidth of the out port. A bandwidth that is less than 0.512 Gbit/
sec is adjusted to the nearest power of 2 value, while a bandwidth that is ranged
from 0.512 Gbit/sec (included) to 1 Gbit/sec (no included) is adjusted to the 0.512
Gbit/sec value. There is no adjustment to the value if a bandwidth is greater or
equal to 1 Gbit/sec.
Bandwidth Demand The maximum bandwidth demand by the in ports.
Flags Always D, indicating a dynamic path. A dynamic path is discovered automatically
by the FSPF path selection protocol.
