Chapter 9: Common Configuration Examples

To-Access: (nothing)

Default Action: Deny

Expand QoS Settings, and enter the following:

Rate Control & Queuing Policy: QoS-Guests

This is the policy that you created in "QoS Rate Limiting.” The SmartPath AP applies these rates and scheduling to users

that belong to this user profile on an individual basis.

CAC Guaranteed Airtime: 0 (default)

Call Admission Control (CAC) monitors the SmartPath AP resource load and airwaves for congestion, and then deter-

mines whether to allow additional VoIP calls using Session Initiation Protocol (SIP) or Vocera services to initiate on that

SmartPath AP. If the SmartPath AP and airwaves are already overused, then a new caller is not permitted to start a call.

Because this user policy will not be applied to voice traffic, it is unnecessary to set this.

Policing Rate Limit a/b/g mode (0-54000 Kbps): 2000

Policing Rate Limit 11n mode (0-2000000 Kbps): 2000

The maximum traffic policing rate for the entire user profile is the same as that for an individual user. By keeping the two

rates the same, a single on-line user is not restricted to a smaller rate than that of the profile to which he or she belongs.

(These rates can be the same as or greater than the individual user rates.)

Setting a rate limit of 2000 kbps provides guests with a basic amount of available bandwidth without interfering with the

bandwidth usage of other users, such as employees.

Scheduling Weight: 5

The weight defines a preference for forwarding traffic. It does not specify a percentage or an amount. Its value is relative

to the weights of QoS schedules in other user profiles in the same WLAN policy.

Because wireless access for guests is mainly a convenience and not a necessity, you assign it a weight that is low in

comparison to the weights of other user profiles to give guests the lowest priority. In this example, 5 is used. Because

this setting is a relative weight, modify it as necessary based on the weights of the other user profiles present.

NOTE: Although SmartPath APs apply policing at all times, they only apply scheduling weights when usage is at maximum

capacity.

SSID

You can provide visitors with secure but unregistered network access by issuing them a preshared key to use when associating

with the guest SSID. A receptionist can provide visitors with the preshared key along with access instructions upon their arrival, as

shown in Figure 9-16. This approach provides visitors with secured network access by using WPA or WPA2 with preshared keys

and TKIP or CCMP (AES) encryption.
