The 40 10GBASE-T ports, 25 to 64 are tri-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.
For example, to configure ports 25 and 26:
ES2-72-primary SEFOS# configure terminal ES2-72-primary SEFOS(config)# interface extreme-ethernet 0/25 ES2-72-primary SEFOS(config-if)# shutdown ES2-72-primary SEFOS(config-if)# speed 1000 ES2-72-primary SEFOS(config-if)# no shutdown ES2-72-primary SEFOS(config-if)# ex ES2-72-primary SEFOS(config)# interface extreme-ethernet 0/26 ES2-72-primary SEFOS(config-if)# shutdown ES2-72-primary SEFOS(config-if)# speed 1000 ES2-72-primary SEFOS(config-if)# no shutdown ES2-72-primary SEFOS(config-if)# end ES2-72-primary SEFOS# write startup-config
For example, to configure ports 31 and 34:
ES2-72-primary SEFOS# configure terminal ES2-72-primary SEFOS(config)# interface extreme-ethernet 0/31 ES2-72-primary SEFOS(config-if)# shutdown ES2-72-primary SEFOS(config-if)# speed 100 ES2-72-primary SEFOS(config-if)# no shutdown ES2-72-primary SEFOS(config-if)# ex ES2-72-primary SEFOS(config)# interface extreme-ethernet 0/34 ES2-72-primary SEFOS(config-if)# shutdown ES2-72-primary SEFOS(config-if)# speed 100 ES2-72-primary SEFOS(config-if)# no shutdown ES2-72-primary SEFOS(config-if)# end ES2-72-primary SEFOS# write startup-config
