ULL UPLEX
The Summit switch provides full-duplex support for all ports. Full-duplex allows
frames to be transmitted and received simultaneously and, in effect, doubles the
bandwidth available on a link. All 10/100 Mbps ports on the Summit autonegotiate for
half- or full-duplex operation.

The Summit2, Summit3, and Summit48 have an optional redundant Gigabit Ethernet
port. Using the redundant port, you can dual-home these models to one or two
switches.
Figure 1-1: Dual-homing configuration
In the event that the active port fails or loses link status, the redundant port is
automatically activated. When the primary port resumes operation, the redundant port
becomes inactive. This feature can be disabled.
The redundant port cannot be used for load sharing when the primary port is active. If
the primary port becomes inactive, the redundant port is activated in the load sharing
configuration.
