Cisco Cisco 4402 Wireless LAN Controller Guia Da Instalação

Link aggregation (LAG) is enabled by default on the integrated wireless LAN 
controller. LAG bundles all of the controller’s distribution system ports into a single 
IEEE 802.3ad port channel. Refer to the Cisco Wireless LAN Controller 
Configuration Guide for more information.

Enter show port summary. The following information appears, showing the status of the 
controller’s distribution system ports, which serve as the data path between the controller and 
Cisco lightweight access points and to which the controller’s management and AP-manager 
interfaces are mapped.

STP   Admin   Physical   Physical   Link   Link    Mcast

Pr  Type   Stat   Mode     Mode      Status   Status  Trap   Appliance   POE

-- ------- ---- ------- ---------- ---------- ------ ------- --------- -------

1  Normal  Forw Enable  Auto       1000 Full  Up     Enable  Enable     N/A

2  Normal  Forw Enable  Auto       1000 Full  Up     Enable  Enable     N/A

A link status of Up indicates that the controller’s ports are fully operational.

Up to two of the following connections are supported in any combination:

1000BASE-T (GigE, front panel, RJ-45 physical port, UTP cable).

1000BASE-SX (GigE, front panel, LC physical port, multi-mode 850nM (SX) fiber-optic links 
using LC physical connectors).

1000BASE-LX (GigE, front panel, LC physical port, multi-mode 1300nM (LX/LH) fiber-optic 
links using LC physical connectors).

Up to four of the following connections are supported in any combination:

1000BASE-T (GigE, front panel, RJ-45, physical port, UTP cable).

1000BASE-SX (GigE, front panel, LC physical port, multi-mode 850nM (SX) fiber-optic links 
using LC physical connectors).

1000BASE-LX (GigE, front panel, LX physical port, multi-mode 1300nM (LX/LH) fiber optic 
links using LC physical connectors.
