Cisco Switch Controllers Accepted these SFP Modules

A distribution system port connects the controller to a neighbor switch and is used as the data path between these two devices. This paper talk about a few common methods on the models that have these options.

Cisco 4402 controllers have two Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 access points (AP). Cisco 4404 controllers have four Gigabit Ethernet distribution system ports, each of which is capable of managing up to 48 APs per port. The 4404-25, 4404-50, and 4404-100 models allow a total of 25, 50, or 100 APs 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/LH 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 transceiver modules, which provide a 1000-Mbps wired connection to a network through a copper link using an RJ-45 physical connector

The Cisco 5508 controllers have eight Gigabit Ethernet distribution system ports through which the controller can manage multiple APs. The 5508-12, 5508-25, 5508-50, 5508-100, and 5508-250 models allow for 12, 25, 50, 100, or 250 APs to join the controller. Cisco 5508 controllers have no restrictions on the number of APs per port. However, Cisco recommends using link aggregation (LAG) or configuring dynamic AP-Manager interfaces on each Gigabit Ethernet port to automatically balance the load. If more than 100 APs are connected to the 5500 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 series controller, make sure that more than one Gigabit Ethernet interface is connected to the upstream switch. The Gigabit Ethernet ports on the 5508 controllers accept these SX/LC/T small-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

The Cisco Catalyst 6500 Series Gigabit Ethernet interface module is a premier modular multilayer switch and delivers secure converged services from the wiring closet to the core, to the data center, to the WAN edge. Designed to complement the many roles that the Cisco Catalyst 6500 Series plays in a network, Cisco Catalyst 6500 Series mixed media Gigabit Ethernet modules offer the broadest selection of media, densities, performance, interoperability, and chassis deployments for enterprises and service providers. The Cisco Catalyst 6500 Series Gigabit Ethernet Interface Module accept these SX, LX/LH, ZX and CWDM/DWDM SFP modules:

GLC-SX-MMD SFP, 1000BASE-SX SFP (multimode only) Dual LC connector
