The following example sets the speed for all ports on the switch to two Gbps:
switch:admin> switchcfgspeed 2
Committing configuration...done.
The following example sets the speed for all ports on the switch to autonegotiate:
switch:admin> switchcfgspeed 0
Committing configuration...done.
Displaying trunking information
The trunkShow command offers an efficient means of listing out all the trunks and members of a trunk.
You can easily discover the peer ports for disabling a port, disconnecting or adding additional members.
Viewing trunks is also useful for when you want to ensure that trunks are formed correctly.
Use the trunkShow command to display the following information about ISL Trunking groups:
• Number identifier.
• Port-to-port connections, listed in the following format: local port number -> remote port number.
• WWNs of the remote switches.
• Deskew values (the time difference, in nanoseconds divided by 10, for traffic to travel over each ISL as
compared to the shortest ISL in the group). The system automatically sets the minimum deskew value of
the shortest ISL to 15.
• Master ports.
To display trunking information:
1. Connect to the switch and log in as admin.
2. Enter the trunkShow command.
This example shows three trunking groups (1, 2, and 3); ports 1, 4, and 14 are masters:
switch:admin> trunkshow
1: 1 -> 1 10:00:00:60:69:04:10:83 deskew 16 Master
0 -> 0 10:00:00:60:69:04:10:83 deskew 15
2: 4 -> 4 10:00:00:60:69:04:01:94 deskew 16 Master
5 -> 5 10:00:00:60:69:04:01:94 deskew 15
7 -> 7 10:00:00:60:69:04:01:94 deskew 17
6 -> 6 10:00:00:60:69:04:01:94 deskew 16
3:14 -> 14 10:00:00:60:69:04:10:83 deskew 16 Master
15 -> 15 10:00:00:60:69:04:10:83 deskew 15
speedlevel Specifies the speed of the link:
• 0—Auto-negotiating mode. The port automatically configures for the
highest speed.
• 1—one Gbps mode. Fixes the port at a speed of one Gbps. Changing the
speed to one Gbps causes the port to be excluded from the trunk group.
• 2—two Gbps mode. Fixes the port at a speed of two Gbps.
• 4—four Gbps mode. Fixes the port at a speed of four Gbps. (HP

• 8—eight Gbps mode. Fixes the port at a speed of four Gbps. (4/256 SAN
