Configuring the Port Speed and Duplex
By default, all 10/100 ports on the 5000 series switch are set to auto-detect
the speed and duplex of the port. However, the 1900 switch has only 12 or
24 10BaseT ports, which cannot be changed. It comes with one or two
FastEthernet ports, which allows you to change the duplex only. The 2820
series has 24 10BaseT ports and 2 modular slots for FastEthernet.
5000 Series Set-Based Switch
Because the ports on a 10/100 card are auto-detect, you don't have to nec-
essarily set the speed and duplex. However, there are situations where the
auto-detect does not work correctly, and by setting the speed and duplex,
you can stabilize the link:
Todd5000> (enable) set port speed 2/1 ?
Usage: set port speed <mod_num/port_num> <4|10|16|100|auto>
