2. Issue the portcfgspeed command. The format is:
portcfgspeed slotnumber/portnumber speedlevel
The following example sets the speed for port 3 on slot 2 to 2 Gbps:
The following example sets the speed for port 3 on slot 2 to auto-negotiate:
To set the speed for all ports on the switch:
1. Connect to the switch and log in as admin.
2. Issue the switchcfgspeed command. The format is:
switchcfgspeed speedlevel
The following example sets the speed for all ports on the switch to 2 Gbps:
where:
slotnumber Specifies the switch slot (this operand is required only for switches with slots,
such as the Core Switch 2/64 and SAN Director 2/128).
portnumber Specifies the port number.
speedlevel Specifies the speed of the link:
• 0 is auto-negotiating mode. The port configures for the highest speed.
• 1 is 1 Gbps mode, which fixes the port at a speed of 1 Gbps. Changing
the speed to 1Gbps causes the port to be excluded from the trunk group.
• 2 is 2 Gbps mode, which fixes the port at a speed of 2 Gbps.
• 4 is 4 Gbps mode, which fixes the port at a speed of 4 Gbps. (SAN
Switch 4/32 only.)

where:
speedlevel Specifies the speed of the link:
• 0 is auto-negotiating mode. The port configures for the highest speed.
• 1 is 1 Gbps, which changes the speed for all of the ports to 1 Gbps,
(eliminating any ISL Trunking group).
• 2 is 2 Gbps mode, which fixes the port at a speed of 2 Gbps.
• 4 is 4 Gbps mode, which fixes the port at a speed of 4 Gbps. (SAN Switch
4/32 only.)
