URL Filter Name
Enter a name that will convey how this URL filter is configured or used. For
example, if you specify a source interface of Fast Ethernet 1, you might enter the
name fa1-parmap. If the filter uses a Websense URL filter server at IP address
192.128.54.23, you might enter websense23-parmap as the name.
Allow Mode
Check this box to enable the router to enter allow mode when the router cannot
connect to any of the URL filtering servers in the server list. When the router is
in Allow mode, all HTTP requests are allowed to pass if the router cannot connect
to any server in the URL filter server list. Allow mode is disabled by default.
URL Filter Alert
Check this box to enable the router to log URL filtering alert messages. URL
filtering alert messages report events such as a URL filtering server going down,
or an HTTP request containing a URL that is too long for a lookup request. This
option is disabled by default.
Audit Trail
Check this box to enable the router to maintain an audit trail in the log. The router
will record URL request status messages that indicate whether an HTTP request
has been permitted or denied and other audit trail messages. This option is
disabled by default.
URL Filter Server Log
Check this box to enable the router to record system messages that pertain to the
URL filter server in the log. This option is disabled by default.
Cache Size
You can set the maximum size of the cache that stores the most recently-requested
IP addresses and their respective authorization status. The default size of this
cache is 5000 bytes. The range is from 0 bytes to 2147483647. The cache is
cleared every 12 hours.
