Chapter 7 Configuring Multiple SSIDs
Configuring Multiple SSIDs
Note You use the ssid command authentication options to configure an authentication type for each SSID. See
Chapter 9, “Configuring an Access Point as a Local Authenticator,” for instructions on configuring
authentication types.
Note When you enable guest SSID mode for the 802.11g radio it applies to the 802.11b radio as well since
802.11b and 802.11g operate in the same 2.4Ghz band.
Use the no form of the command to disable the SSID or to disable SSID features.
This example shows how to:
• Name an SSID
• Configure the SSID for RADIUS accounting
• Set the maximum number of client devices that can associate using this SSID to 15
• Assign the SSID to a VLAN
• Assign the SSID to a radio interface
AP# configure terminal
AP(config)# dot11 ssid batman
AP(config-ssid)# accounting accounting-method-list
AP(config-ssid)# max-associations 15
AP(config-ssid)# vlan 3762
AP(config-ssid)# exit
AP(config)# interface dot11radio 0
AP(config-if)# ssid batman
AP(config-if)#end
Viewing SSIDs Configured Globally
Use this command to view configuration details for SSIDs that are configured globally:
AP# show running-config ssid ssid-string
Using Spaces in SSIDs
In Cisco IOS Release 12.3(7)JA and later, You can include spaces in an SSID, but trailing spaces (spaces
at the end of an SSID) are invalid. However, any SSIDs created in previous versions having trailing
spaces are recognized. Trailing spaces make it appear that you have identical SSIDs configured on the
same access point. If you think identical SSIDs are on the access point, use the show dot11 associations
privileged EXEC command to check any SSIDs created in a previous release for trailing spaces.
For example, this sample output from a show configuration privileged EXEC command does not show
spaces in SSIDs:
ssid buffalo
vlan 77
authentication open
ssid buffalo
vlan 17
authentication open
