URLF-3
Error Message %URLF-3-ALLOW_MODE: Connection to all the URL filter servers are down
and the allow mode is ’[chars]’
Explanation
No URL filter servers are available. If the allow mode is on, the router will pass HTTP
traffic; otherwise, the router will drop HTTP traffic and close the TCP connection.
Recommended Action Check the status of the URL filter server (WebSense/N2H2). Restart the server
if necessary. If the server cannot be recovered, install another URL filter server and configure the
new server location on the router.
Error Message %URLF-3-MAX_REQ: The number of pending request exceeds the maximum
limit [dec]
Explanation
The number of pending URL authentication requests from the URL filter server exceeds
the maximum limit. As a result, HTTP requests will be dropped.
Recommended Action No action is required.
Error Message %URLF-3-RESOURCE_ALLOC_FAILED: The resource allocation failed for URL
filter subsystem
Explanation
The URL filtering feature is unable to allocate memory for various data structures.
Recommended Action Disable unused features or check for other reasons why the router may be
running out of memory.
Error Message %URLF-3-SERVER_DOWN: Connection to the URL filter server [IP_address]
is down
Explanation
The connection between the router and a URL filter server is down. If multiple servers
are configured, the router will try another server for URL authentication. If no URL filter server is
available, the router will check the allow mode. If the allow mode is ’on,’ the router will pass HTTP
traffic; otherwise, the router will drop HTTP traffic and close the TCP connection.
Recommended Action Check the status of the URL filter server (WebSense/N2H2). Restart the server
if necessary. If the server cannot be recovered, install another URL filter server and configure the
new server location on the router.
Error Message %URLF-3-URL_TOO_LONG: URL sent from [IP_address] is too long (more than
[dec] bytes), possibly a fake packet?
Explanation
The URL in the HTTP GET request is too long. Because the packet may be fake, it will
be dropped.
Recommended Action No action is required.
