Configuring the AP

2.Configure the settings as required:

DTIM Interval Configure DTIM packet frequency as a multiple of beacon packets. The DTIM Interval indicates how many beacons equal one cycle. Users should not modify this setting or risk damaging the configuration.

BC/MC Q Max Determines the memory allocated for the queue used in the AP to temporarily hold broadcast/ multicast messages. Unit measure is in packets and corresponds to maximum-sized Ethernet packets. The default is 10.

Max Retries (d) The maximum allowed retries before aborting a single data packet transmission. The default is 15. Users should not modify this setting or risk damaging the configuration.

Max Retries (v) The maximum allowed retries before aborting a single voice packet transmission. The default is 5. Users should not modify this setting or risk damaging the configuration.

Multicast Mask Supports broadcast download protocols for any MU,

(d)typically Point-of-Sale terminals, requiring the expedited download of a new operating image over the network instead of using a local nonvolatile drive.

All multicast downstream data packets that match the top 32 bits of the multicast mask are forwarded immediately instead of being queued for transmission at the next DTIM interval.

Multicast Mask Supports broadcast, or party-line, voice

(v)communications. All multicast downstream data packets that match the top 32 bits of the multicast mask are forwarded immediately instead of being queued for transmission at the next DTIM interval.
