Trunkshow - Brocade Communications Systems 8 Command Reference Manual

2

trunkShow

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
Port to port connections
WWN
Domain
deskew
Master
When used with the -perf option, the command output displays the following additional
information:
bandwidth
throughputDisplays the throughput (Rx, Tx, and the combined total for Tx+Rx) of the trunk group.
%
978
Displays each trunking group on a switch. All ports that are part of this
trunking group are displayed.
Displays the port-to-port trunking connections.
Displays the world wide name of the connected port.
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.
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.
Displays whether this trunking port connection is the master port connection
for the trunking group.
The bandwidth (Rx, Tx, and the combined total for Tx+Rx) of the trunk group.
Values are displayed as either bits per second (Bps), kilobits per second
(Kbps), megabits per second (Mbps), or gigabits per second (Gbps), rounded
down to the next integer.
Results are displayed for the previous second. Values are displayed as either
bits per second (Bps), kilobits per second (Kbps), megabits per second
(Mbps), or gigabits per second (Gbps), rounded down to the next integer.
Displays the percentage of link utilization (Rx, Tx, and the combined total for
Tx+Rx) . Even when the link utilization is 100% , the throughput value will be
lesser than the bandwidth value, due to the 8b/10b encoding and the control
words transmitted. For example, the throughput for an 8Gbps link at 100%
utilization would be approximately 6.8Gbps.
