Setting Priority In 12.4(3)Jk And Later Releases; Dynamic Channel Width (4.9Ghz Wmic Only) - Cisco C3201FESMIC-TP= - 3201 Fast EN Switch Mobile Interface Card Expansion Module Software Configuration Manual

Setting Priority in 12.4(3)JK and Later Releases

You no longer need to enable MCP by running the client profile multiple command. Any SSID
configured into the dot11 interface in these client modes is automatically picked up as an active client
profile.
In addition, you no longer need a VLAN ID to combine each SSID with its encryption settings. Instead,
the encryption settings have been moved from the dot11 interface into each SSID profile. For more
information, see
The new client profile supports priority setting. The higher priority SSID may have more opportunities
to get associated compared to lower priority SSIDs.
Setting Priority in 12.4(3)JK and Later Releases
In 12.4(3)JK and later release, each SSID profile can be configured with a priority level (1 to 16) if the
WMIC works in client modes. The highest priority level is 1 and the lowest is 16.
By default, each profile is configured with the lowest priority level. The priority level does not appear
in the running configuration.
For example, to set an SSID with a scanning priority of 5, you would enter the following:
client# configure terminal
client(config)# dot11 ssid sample
client(config-ssid)# priority 5
client(config-ssid)#end
The higher priority SSID may have more opportunities to get associated as opposed to lower priority
SSIDs if their matching root devices all exist in the same wireless environment. However, there is no
guarantee that the higher priority SSID will always get preference over lower priority SSIDs. There are
many uncertainties in the wireless environment that affect association, such as signal strength, wireless
qualities, root side traffic loads, and receiving collisions.

Dynamic Channel Width (4.9GHz WMIC only)

Cisco 3202 WMICs support dynamic channel width for 4.9GHz. For 4.9GHz WMIC, the channel width
setting is added into SSID profile to achieve dynamic channel bandwidth selection.
All the 3200 WMIC platforms for the following client modes: non-root, workgroup-bridge, and universal
workgroup-bridge support dynamic channel width for 4.9GHz.
To achieve dynamic bandwidth selection, each SSID can be configured with one of the channel
bandwidths 5, 10 or 20MHz. This applies only to client modes of 4.9GHz WMIC. By default, each SSID
is with 5MHz channel width. Below is the example to demonstrate how to configure the channel width
under SSID:
(config-ssid)#channel ?
(config-ssid)#channel width ?
