Combo Ports

The combo ports are two gigabit Ethernet ports and two SFP ports on the router that are labeled
identically.
The GE and SFP ports share the same physical ports or connections and are labelled identically on the
router (ETH 2/1, ETH 2/2) and in the software (GE 2/1, GE 2/2).
on the router and in software.
The Gigabit Ethernet ports support copper GE connections and the SFP modules support fiber optic GE
connections. Only one connection on each interface (ETH 2/1 and ETH 2/2) can be in use at any time.
These ports automatically detect the type of any connected cable (fiber or copper) and then switch to the
corresponding mode (fiber or copper).
