trunkShow
Displays trunking information.
Synopsis trunkshow [-perf]
Description Use this command to display trunking information of both E_Ports and EX_Ports. The command
displays the following fields:
Trunking Group Number
Displays each trunking group on a switch. All ports that are part of this
trunking group are displayed.
Port to port connections
Displays the port-to-port trunking connections.
WWN Displays the world wide name of the connected port.
Domain Displays the domain IDs of the switches directly connected to the physical
ports. In case of an FC Router backbone fabric interlinking several edge
fabrics, the domain ID displayed for an E_Port trunk refers to a domain of a
switch within the backbone fabric, whereas the domain ID displayed for an
EX_Port trunk refers to the domain ID of a switch in the edge fabric. Because
they are independent fabrics, it is possible that both the backbone and the
edge fabric may have the same domain ID assigned to switches. If this is the
case, run switchShow to obtain information on the port types of the local
switch and the WWNs of the remote switches. Refer to the Example section
for an illustration.
deskew The difference between the time it takes for traffic to travel over each ISL
compared to the time it takes through the shortest ISL in the group. The value
is expressed in nanoseconds divided by 10. The firmware automatically sets
the minimum deskew value for the shortest ISL, which is 15.
Master Displays whether this trunking port connection is the master port connection
for the trunking group.
When used with the -perf option, the command output displays the following additional
information:
bandwidth The total bandwidth (Rx and Tx) of the trunk group. Values are displayed as
either bytes per second (B), kilobytes per second (KB), megabytes per second
(MB), or gigabytes per second (GB), rounded down to the next integer.
throughput Displays the throughput (Rx and Tx) of the trunk group. Results are displayed
for the previous second. Values are displayed as either bytes per second (B),
kilobytes per second (KB), megabytes per second (MB), or gigabytes per
second (GB), rounded down to the next integer.
% Displays the percentage of link utilization.
Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS Commands" and Appendix A, "Command
Availability" for details.
