Setting the same speed for all ports on the switch

1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the switchCfgSpeed command.
Example of setting the switch speed
The following example sets the speed for all ports on the switch to 8 Gbps:
switch:admin> switchcfgspeed 8
Committing configuration...done.
The following example sets the speed for all ports on the switch to autonegotiate:
switch:admin> switchcfgspeed 0
Committing configuration...done.

Blade terminology and compatibility

Before configuring a chassis, familiarize yourself with the platform CP blade and port blade
nomenclature, as well as the port blade compatibilities. Often in procedures, only the abbreviated
names for CP and port blades are used (for example, the FC4-16 blade). Table 4 includes CP and
port blade abbreviations and descriptions.
