Defining the polling interval
The polling interval determines how often the Brocade device checks the status of the entries in
the DNS cache table to determine if the information for that host has changed. If the TTL value of
the cache entry is expired the entry is removed from the cache-table.
To define a polling interval, enter the following command.
BigIron RX(config)#ip dns poll-interval 7
Syntax: ip dns poll-interval <minutes>
Enter the polling interval in minutes. The default is 1 minute.

The show ip dns cache-table output
Displays...
The complete, qualified domain name of the host.
Indicates if the entry is dynamic or static and if the information for the
domain is up to date:
•
TMP – Entry is dynamic
•
STA – Entry is static
•
OK – Information for the entry is up to date
•
EX – The entry is expired and would not be used. Such an entry would
be deleted from the cache table at next cache poll refresh.
If the entry is dynamic (TMP) this value shows how long the entry remains in
the DNS cache table. If the entry is static (STA), it remains in the DNS cache
table and never changes until it is manually removed or the DNS cache table
is cleared.
The IP address of the entry.
