| Configuring the WSM using Device Manager |
Before enabling filtering on any port, you should configure a default filter. Default filters handle traffic not covered by any other filter. You must set all criteria in the default filter to the full range possible (Any).
Default filters are recommended (but not required) when configuring filters for IP traffic control and redirection. Default filters can increase session performance although they use session binding resources. If you observe higher than acceptable binding failures in the server load balance maintenance statistics (from the Device view, choose Graph > L4 > SLB> Maintenance), you can remove some default filters. For more information, see Maintenance statistics.
When configuring a default filter, give it the lowest order of precedence (Filter index 2048), configure the Action to Deny, and set all matching criteria to Any. If no other filter acts on the traffic, Filter 2048 processes it, denying and logging unwanted traffic.
