Configure 1 Gbps Mode on SFP+ Interfaces

The four SFP+ ports, 21 to 24, are dual-speed capable ports and can provide 1 Gbps connectivity when used with the supported transceivers and configured for 1 Gbps operation from the SEFOS CLI.

• To configure a 1 Gbps fiber link, use the supported 10 Gbps/1 Gbps SFP+ transceiver (PN x2129a). The speed must be changed to 1 Gbps on the appropriate port (see the following example).

• To configure a 1 Gbps copper link, use the supported SFP transceiver (PN x2123a), which provides a RJ-45 interface. This is a 1 Gbps-only transceiver and the speed must be changed to 1 Gbps on the appropriate port (see the following example).

1. Obtain the SEFOS prompt.
2. Configure the speed to 1 Gbps.

   For example, to configure ports 21 and 22:

   SEFOS# config terminal
   SEFOS(config)# interface range extreme-ethernet 0/21-22
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# speed 1000
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# end
   SEFOS# write startup-config
