flash info
Displays flash information, including whether flash aliasing is on
or off. See config dns flash spoof for information.
Flash Information:
Flash State: Disabled Aliasing: Disabled
Polling Interval: 10 Number of Polls: 100
Max Broadcast Delay: 500 Drop Misses: 3
Aliasing: With multiple 7190s, Flash responses can pass through
a firewall because of the aliasing of source IPs.
Polling Interval: How frequently Flash Peers are polled to
determine the network latency
Number of Polls: The number of Flash Peer polls to be used in
calculating the average network latency between Flash Peers. The
more polls, the slower the 7190 reacts to bursts of network
congestion; but it is also slower to recover from long periods of
congestion.
Max Broadcast Delay: The maximum amount of time that a
DNS response can be delayed to compensate for network latency
between Flash Peers. If exceeded, may become out of sync with
other peers.
Drop Misses: The number of consecutive chances allowed for a
response (to a poll message) before the peer 7190 is considered
unavailable.
