Configure Speed on the 10GBASE-T Interfaces

The 20 10GBASE-T ports, 1 to 20, are triple-speed capable ports and can provide 10 Gbps, 1 Gbps, and 100 Mbps connectivity. The 10GBASE-T ports operate in autonegotiation mode only and support all three speeds by default. For most deployments, the default setting would be optimal, permitting link-partners with any speed to link up. If required, the maximum advertised speed can be changed from the SEFOS CLI.

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

   For example, to configure ports 11 and 12.

   SEFOS# 
   SEFOS(config)# interface range extreme-ethernet 0/11-12
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# speed 1000
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# end
   SEFOS# write startup-config
   

   ---

   Note -  The ports only advertise 1 Gbps and 100 Mbps speeds.

   ---

3. Configure the maximum advertised speed to 100 Mbps.

   For example, to configure ports 1 and 4.

   SEFOS# config terminal
   SEFOS(config)# interface extreme-ethernet 0/1
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# speed 100
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# exit
   SEFOS(config)# interface extreme-ethernet 0/4
   SEFOS(config-if)# shutdown
   SEFOS(config-if)# speed 100
   SEFOS(config-if)# no shutdown
   SEFOS(config-if)# end
   SEFOS# write startup-config

   Note -  The ports only advertise 100 Mbps and can only link up with a link-partner at 100 Mbps (if supported by the link-partner).
