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.
deskew The time difference for traffic to travel over each F_Port trunk as compared to
the F_Port trunk with the shortest travel time in the group. The value is
expressed in nanoseconds divided by 10. The firmware automatically sets the
minimum deskew value of the shortest F_Port trunk travel time to 15.
Master Identifies the master port of the trunk group.
Execution of this command is subject to the following restrictions:
1. Only F_Port trunk ports are allowed to be part of a TA. E/F/L/EX_Port will be persistently
disabled. Private L_Ports remain online but will not run traffic.
2. Only one trunk master per TA is permitted. The second trunk master is persistently disabled.
3. The entire TA trunk group shares the same port WWN.
4. The port must be disabled before a TA can be assigned to a port or removed from a trunk
group.
5. There is one port whose Default Area is the same as its Trunk Area. You cannot remove that
port from the trunk group unless The TA is removed from all ports in the trunk group.
6. You must enable trunking on all ports to be included in a TA before you can create a TA. Use
portCfgTrunkPort or switchCfgTrunk to enable Trunking on a port or on all ports of a switch.
7. N_Port ID Virtualization (NPIV) support is provided for up to 255 devices per TA. Note that this
decreases the number of devices available per port, since all participating ports share the
same area.
8. F_Port trunking is only supported in CORE PID formats.
9. Certain port configuration features are not supported within a TA and the command fails if one
of these features is enabled on a port within the trunk group. These features include FastWrite,
Port Swapping, Port Mirroring, Long Distance, Inter-chassis links (ICL), and FICON.
10. Ports from different Admin Domains are not allowed to join the same Trunk Area group.
11. On the Brocade FC4-48C, F_Port masterless trunk ports are not supported on ports 16 - 47.
12. Ports included in a TA share the same port index. The original port index may be removed in the
process. This means that D, I zones referring to these indices are no longer part of the switch.
