Note
traffic can use Category 3 or Category 4 cables.
When connecting the switch to workstations, servers, routers, and Cisco IP
Phones, be sure that the cable is a straight-through cable. When connecting the
switch to switches or hubs, use a crossover cable. When using a straight-through
or crossover cable for 1000BASE-T connections, be sure to use a twisted

You can use the mdix auto interface configuration command in the CLI to enable
Note
the automatic medium-dependent interface crossover (Auto-MDIX) feature.
When the feature is enabled, the switch detects the required cable type for copper
Ethernet connections and configures the interfaces accordingly. Therefore, you
can use either a crossover or a straight-through cable for connections to a copper
10/100 or 1000BASE-T SFP module port on the switch, regardless of the type of
device on the other end of the connection.
The Auto-MDIX feature is disabled by default. For configuration information for
this feature, refer to the switch software configuration guide or the switch
command reference.

Note
that do not fully support IEEE 802.3AF, might not support PoE when connected
to the switches by a crossover cable.
