Switching 8-9 autonegotiating end selects 100Mbps half-duplex operation. Using 100Mfauto at the “fixed” end of the link would allow the autonegotiating end to autonegotiate 100Mbps full-duplex mode. This gains the benefits of autonegotiation while forcing operation at the desired speed. Also, if you override a port’s autonegotiation by setting it to a fixed speed and duplex mode, automatic MDI/MDI-X detection is also overridden. The port defaults to MDI-X. To display current speed and duplex mode settings, use the show switch port command on page 8-135. To activate autonegotiation at any time on ports that are set to autonegotiate, use the activate switch port command on page 8-48. Port types and speed For different types of port, the valid options are shown in the following table. 10/100 copper ports on Rapier 24i Rapier 48i 100 fibre ports on Rapier 16fi AT-A39 uplink AT-A35 AT-A42 uplinks AT-A40 AT-A41 uplinks 10Mhalf Yes - Yes - - 10Mfull Yes - Yes - - 100Mhalf Yes Yes Yes - Yes 100Mfull Yes Yes Yes - Yes 1000Mhalf - - Yes - - 1000Mfull - - Yes Yes - 10Mauto Yes - Yes - - 10Mhauto Yes - Yes - - 10Mfauto Yes - Yes - - 100Mauto Yes - Yes - - 100Mhauto Yes - Yes - Yes 100Mfauto Yes - Yes - Yes 1000Mhauto - - Yes - - 1000Mfauto - - Yes Yes - Yes - Yes Yes Yes Speed autonegotiate Switch Instances on 48-Port Switches The Rapier 48i has two switch instances, known as instance “0” and “1”. Ports 1 to 24 and the uplink port 49 are on instance 0. Ports 25 to 48 and the uplink port 50 are on instance 1. There are minor restrictions on 48-port switches for some features, such as port trunking, private vlans, protected vlans, and classifier-based packet filters.
