Supported 802.11a and 802.11b/g ProtocolsSupported 802.11a and 802.11b/g Protocols
The 802.11a and 802.11b/g protocols can be independently enabled or disabled.
•Use the show sysinfo command to view the 802.11a and 802.11b/g enabled/disabled status.
•Make sure these protocols are configured to agree with your wireless network plan and to
comply with the Country regulations entered in the previous step using the following
commands:
>config 802.11a enable network
>config 802.11a disable network
>config 802.11b enable network
>config 802.11b disable network

•Use the show sysinfo command to verify that the Cisco Wireless LAN Controller has stored

your input. Continue with the next parameter.
Users and PasswordsUsers and Passwords
After you have configured other system parameters, you are urged to change the username and
password so unauthorized personnel cannot easily log into the Cisco Wireless LAN Controller.
•Use the show mgmtuser command to view the current management user names.
•Use the following commands to add new usernames and add or change passwords:
>config mgmtuser add <username> <password> [read-write/read-only]
>config mgmtuser password <username> <new password>
where <username>, <password> and <new password> = Any ASCII character string, up to 24
characters, case sensitive, with no spaces.
•Use the show mgmtuser command to verify that your users have been accepted by the system.

Configuring Cisco Wireless LAN Controller InterfacesConfiguring Cisco Wireless LAN Controller Interfaces
As described in the Distribution System Ports section, the Cisco 2000 Series Wireless LAN Controller
has up to four physical ports, the Cisco 4100 Series Wireless LAN Controller has two redundant physical
ports, and the Cisco 4400 Series Wireless LAN Controller has one (4402) or two (4404) pairs of
redundant physical ports. This means that the Cisco 4100 Series Wireless LAN Controller can physically
connect to one subnet, and the Cisco 2000 Series Wireless LAN Controller and Cisco 4400 Series
Wireless LAN Controllers can physically connect to multiple subnets.
Each of the physical ports can have multiple Interfaces applied to it:
•The Management Interface controls communications with network equipment for all physical
ports in all cases.
When the Cisco WLAN Solution is operated in Layer 2 Mode (see Layer 2 and Layer 3 LWAPP
Operation), the Management Interface also controls communications between the Cisco
Wireless LAN Controller and Cisco 1000 Series Lightweight Access Points.
When the Cisco WLAN Solution is operated in Layer 3 Mode, the Management Interface no
longer controls communications between the Cisco Wireless LAN Controller and Cisco 1000
Series lightweight access points.
•When the Cisco WLAN Solution is operated in Layer 3 Mode (see Layer 2 and Layer 3 LWAPP
Operation), the AP-Manager Interface controls all communications between the Cisco Wireless
LAN Controller and Cisco 1000 Series Lightweight Access Points.
•Each physical port can also have between one and 512 Operator-Defined Interfaces, also
known as VLAN Interfaces, assigned to it. Each Operator-Defined Interface is individually
