Combination Ports and Failover
Summit family switches provide two or four uplink ports implemented as combination ports that pair a
copper port using RJ-45 connectors with an optical port using LC connectors. The copper port operates
as an autonegotiating 10/100/1000BASE-T port. The optical port allows Gigabit Ethernet uplink
connections through Extreme Networks small form factor pluggable (SFP) interface modules. See the
individual switch descriptions for the port numbers of the combination ports on each switch model.
Summit family switches support an automatic failover from an active fiber port to a copper backup or
from an active copper port to a fiber port. If one of the uplink connections fails, the Summit uplink
connection automatically fails over to the second connection. To set up a redundant link on one of the
combination ports, connect the active 1000BASE-T and fiber links to both the RJ-45 and SFP interfaces of
that port.
Gigabit Ethernet uplink redundancy on the Summit family switches follows these rules:
● With both the SFP and 1000BASE-T interfaces connected on a combination port, only one interface
can be activated. The other is inactive.
● If only one interface is connected, the switch activates the connected interface.
● The switch determines whether the port uses the fiber or copper connection based on the order in
which the connectors are inserted into the switch. When the switch senses that an SFP and a copper
connector are inserted, the switch enables the uplink redundancy feature. For example, if you first
connect copper ports 25 and 26 on a Summit XX250e-24t switch, and then insert SFPs into ports 25
and 26, the switch assigns the copper ports as active ports and the fiber ports as redundant ports.
Hardware determines when a link is lost and swaps the primary and redundant ports to maintain
stability. After a failover occurs, the switch keeps the current port assignment until another failure
occurs or a user changes the assignment using the CLI. For more information about configuring
automatic failover on combination ports, see the ExtremeXOS Concepts Guide.
