Configuration of per-user/role bandwidth contract on Instant 4.0

  • 1.  Configuration of per-user/role bandwidth contract on Instant 4.0

    Posted Apr 20, 2014 01:41 AM

    From Instant 4.0, we could configure the Bandwidth contact for per role/user based whereas in earlier released bandwidth contracted accounted both for upstream and downstream traffic.

     

     

                                                    SSID> Advance options

    Navigate to Security -> Roles -> Select the Role ->  Click on “New” under the Access Rules tab -> Select Bandwidth contract under Rule Type

     

     

    iap-bw2.jpg

     

     

    CLI:-
    ------

    Per-Role Bandwidth configuration:

    6c:f3:7f:cc:a5:08 (config) # wlan access-rule bandwidth-contract

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # bandwidth-limit upstream 3000

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # bandwidth-limit downstream 3000

     

    Per-User Bandwidth configuration:

    6c:f3:7f:cc:a5:08 (config) # wlan access-rule bandwidth-contract

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # bandwidth-limit peruser upstream 3000

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # bandwidth-limit peruser downstream 3000

     

    Removing Bandwidth contract:

    6c:f3:7f:cc:a5:08 (config) # wlan access-rule bandwidth-contract

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # no bandwidth-limit upstream 

    6c:f3:7f:cc:a5:08 (Access Rule "bandwidth-contract") # no bandwidth-limit downstream

     

     

    If the user had per-user bandwidth in earlier releases configured under the SSID, this value will be treated as “downstream bandwidth contract” for the SSID role.

     

    Example:
    ---------------

    Wlan 6c:f3:7f:cc:a4:3c (config) # wlan ssid-profile qa-IAP-BWC-s3

    6c:f3:7f:cc:a4:3c (SSID Profile “qa-IAP-BWC-s3 ") # per-user-bandwidth-limit 2000

    6c:f3:7f:cc:a4:3c (SSID Profile “qa-IAP-BWC-s3 ") # end

     

    6c:f3:7f:cc:a4:3c# show access-rule qa-IAP-BWC-s3

    Access Rules

    ------------

    Dest IP  Dest Mask  Dest Match  Protocol (id:sport:eport)  Action  Log  TOS  802.1P  Blacklist  Mirror  DisScan  ClassifyMedia

    -------  ---------  ----------  -------------------------  ------  ---  ---  ------  ---------  ------  -------  -------------

    any      any        match       any                        permit

    Vlan Id           :0

    ACL Captive Portal:disable

    ACL ECP Profile   :default

    CALEA             :disable

    Bandwidth Limit   :downstream 2000 kbps (peruser) upstream disable

     

     

    However from Instant 4.0 bw-contract can be configured both upstream and downstream.

    What happens when the user reaches the quota? Does the contract renew the next day etc? Also, is it possible to set a monthly bandwidth quota?

    Lexc,

     

    The bandwidth contract when applied for any user or any role will limit that user/role to a total upload or download bandwidth specified. For example, a Role "Instant" might have 5 devices and their total bandwidth could be limited to 2000 kbps (upload or download, as configured). So, all these devices together cannot exceed a total upload/download of 2000 kbps.

    Thanks Immi,

     

    I think I phrased my question wrong though, what I meant is, is it possible to allow a user 50mb of data for the month and then they will be capped? And then at the begining of the next month allow them another 50mb of data?

    Lexc,

     

    A bandwidth contract limits sustained bandwidth for a user, not total bandwidth.  If you establish a bandwidth contract for 1 megabit, for example, when the user does a speedtest, the test will not pass 1 megabit.  The scenario you are discussing involves total bandwidth.  That can only be accomplished with an external policy engine such as ClearPass that would total the consumed bandwidth using radius accounting and enforce the consumed bandwidth using a policy.
