Chapter7 Configuring Multiple SSIDs
Including an SSID in an SSIDL IE
This example shows how to configure IP redirection only for packets sent to the specific TCP and UDP
ports specified in an ACL applied to the BVI1 interface. When the access point receives packets from
client devices associated using the SSID robin, it redirects packets sent to the specified ports and
discards all other packets:
AP# configure terminal
AP(config)# interface bvi1
AP(config-if-ssid)# ip redirection host 10.91.104.91 access-group redirect-acl in
AP(config-if-ssid)# end
Including an SSID in an SSIDL IE
The access point beacon can advertise only one broadcast SSID. However, you can use SSIDL
information elements (SSIDL IEs) in the access point beacon to alert client devices of additional SSIDs
on the access point. When you designate an SSID to be included in an SSIDL IE, client devices detect
that the SSID is available, and they also detect the security settings required to associate using that SSID.
Note When multiple BSSIDs are enabled on the access point, the SSIDL IE does not contain a list of SSIDs;
it contains only extended capabilities.
Beginning in privileged EXEC mode, follow these steps to include an SSID in an SSIDL IE:
Use the no form of the command to disable SSIDL IEs.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 interface dot11radio { 0 | 1 } Enter interface configuration mode for the radio interface.
The 2.4-GHz radio and the 2.4-GHz 802.11n radio is 0.
The 5-GHz radio and the 5-GHz 802.11n radio is 1.
Step3 ssid ssid-string Enter configuration mode for a specific SSID.
Step4 information-element ssidl
[advertisement] [wps]
Include an SSIDL IE in the access point beacon that advertises
the extended capabilities for the access point, such as 802.1x
and support for Microsoft Wireless Provisioning Services
(WPS).
Use the advertisement option to include the SSID name and
capabilities in the SSIDL IE. Use the wps option to set the WPS
capability flag in the SSIDL IE.
