Broadcast Control
You also can enhance bandwidth availability on an SSID by enabling the following broadcast control
features:
Proxy ARP
—switch responds on behalf of wireless clients to ARP requests for their IP
addresses.
DHCP Restrict
—switch captures and does not forward any traffic except DHCP traffic for
a wireless client who is still being authenticated and authorized.
No Broadcast
—Sends unicasts to clients for ARP requests and DHCP Offers and Acks
instead of forwarding them as multicasts.
All these broadcast control options are disabled by default.
Static CoS
You can configure MSS to mark all wireless traffic on an SSID with a specific CoS value. When static
CoS is enabled, the AP marks all traffic between clients and the switch for a given SSID with the static
CoS value. The static CoS value must be configured on the SSID’s service profile.
Static CoS is the simplest method of CoS marking to configure. However, the static CoS value applies
to all traffic regardless of traffic type. To instead assign CoS based on specific traffic types within an
SSID, use an ACL.
Note:
When static CoS is enabled, you cannot override the static CoS value by using ACLs to mark
CoS.
Overriding CoS
You can configure an ACL that marks packets that match the ACL with a specific CoS value. CoS is not
changed in packets that do not match the ACE (ACL rule) that sets the CoS.
Note:
If static CoS is enabled, the static CoS value is always used. The CoS cannot be changed using
an ACL.
