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 plus the
minimum deskew value. 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 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.
throughput
Displays the throughput (Rx, Tx, and the combined total for Tx+Rx) of the trunk
group. 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.
