NOTE
When configuring the Summit 200-48 switch, all ports specified as mirrored ports and mirroring port, or
ACL ingress ports and egress port, must belong to the same port group. Port group 1 consists of ports
1 through 24 and port 49; port group 2 consists of ports 25 through 48 and port 50.

Uplink Redundancy on the Summit 200-24fx and Summit 200-24fx-TAA Switch
Gigabit Ethernet uplink redundancy on the Summit 200-24fx and Summit 200-24fx-TAA switch follows
these rules:
these rules:
•
Only one interface on each port can be active at a time. For example, on port 25, with both the
mini-GBIC and 1000BASE-T interfaces connected, only one interface can be activated. The other is
inactive.
mini-GBIC and 1000BASE-T interfaces connected, 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 a mini-GBIC and a
copper connector are inserted, the switch enables the uplink redundancy feature. For example, if you
first insert mini-GBICs into ports 25 and 26, and then connect copper ports 25 and 26, the switch
assigns the copper ports as redundant ports.

To set up a redundant link on a port, connect the active fiber and 1000BASE-T links to both the RJ-45
and mini-GBIC interfaces of port 49. The switch defaults to the fiber link. If the fiber link fails during
operation, the switch automatically activates the redundant 1000BASE-T link.

operation, the switch automatically activates the redundant 1000BASE-T link.
Hardware determines when a link is lost and swaps the primary and redundant ports to maintain
stability. After a failover occurs, the switch keeps or sticks with the current port assignment until there
is another failure or a user changes the assignment using the CLI. To change the uplink failover
assignment, use the following command:
stability. After a failover occurs, the switch keeps or sticks with the current port assignment until there
is another failure or a user changes the assignment using the CLI. To change the uplink failover
assignment, use the following command:
configure ports <nnn> preferred-medium {copper} | {fiber} |[force]
The default preferred-medium is fiber. If you use the
force
option, it disables automatic failover. If you
force the preferred-medium to fiber and the fiber link goes away, the copper link is not used, even if
available.

Full-Duplex Support
The Summit 200 switches provide 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 200 switch autonegotiate for half- or full-duplex operation.
