Storm Threshold; Intra Bss - Avaya AP-3 User Manual

Storm Threshold

Storm Threshold is an advanced Bridge setup option that you can use to protect the network
against data overload by:
Specifying a maximum number of frames per second as received from a single network
●
device (identified by its MAC address).
Specifying an absolute maximum number of messages per port.
●
The Storm Threshold parameters allow you to specify a set of thresholds for each port of the AP,
identifying separate values for the number of broadcast messages/second and Multicast
messages/second.
When the number of frames for a port or identified station exceeds the maximum value per
second, the AP will ignore all subsequent messages issued by the particular network device, or
ignore all messages of that type.
Address Threshold: Enter the maximum allowed number of packets per second.
●
Ethernet Threshold: Enter the maximum allowed number of packets per second.
●
Wireless-Slot A and Wireless-Slot B Threshold: Enter the maximum allowed number of
●
packets per second.

Intra BSS

The wireless clients (or subscribers) that associate with a certain AP form the Basic Service Set
(BSS) of a network infrastructure. By default, wireless subscribers in the same BSS can
communicate with each other. However, some administrators (such as wireless public spaces)
may wish to block traffic between wireless subscribers that are associated with the same AP to
prevent unauthorized communication and to conserve bandwidth. This feature enables you to
prevent wireless subscribers within a BSS from exchanging traffic.
Although this feature is generally enabled in public access environments, Enterprise LAN
administrators use it to conserve wireless bandwidth by limiting communication between
wireless clients. For example, this feature prevents peer-to-peer file sharing or gaming over the
wireless network.
To block Intra BSS traffic, set Intra BSS Traffic Operation to Block.
●
To allow Intra BSS traffic, set Intra BSS Traffic Operation to Passthru.
