Distribution System Ports
A distribution system port connects the controller to a neighbor switch and serves as the data path
between these two devices.

provides a list of ports per controller.
Controller Ports
Cisco 2000 series controllers have four 10/100 copper Ethernet distribution system ports through
which the controller can support up to six access points.
Cisco 4100 series controllers have two fiber gigabit Ethernet distribution system ports through
which the controller can support up to 36 access points.
Cisco 4402 controllers have two gigabit Ethernet distribution system ports, each of which is capable
of managing up to 48 access points. However, Cisco recommends no more than 25 access points per
port due to bandwidth constraints. The 4402-25 and 4402-50 models allow a total of 25 or 50 access
points to join the controller.
Cisco 4404 controllers have four gigabit Ethernet distribution system ports, each of which is capable
of managing up to 48 access points. However, Cisco recommends no more than 25 access points per
port due to bandwidth constraints. The 4404-25, 4404-50, and 4404-100 models allow a total of 25,
50, or 100 access points to join the controller.
The gigabit Ethernet ports on the 4402 and 4404 controllers accept these SX/LC/T small
form-factor plug-in (SFP) modules:
- 1000BASE-SX SFP modules, which provide a 1000-Mbps wired connection to a network
through an 850nM (SX) fiber-optic link using an LC physical connector
- 1000BASE-LX SFP modules, which provide a 1000-Mbps wired connection to a network
through a 1300nM (LX/LH) fiber-optic link using an LC physical connector
- 1000BASE-T SFP modules, which provide a 1000-Mbps wired connection to a network
through a copper link using an RJ-45 physical connector
