Configuring Interface-Specific Counters

When you configure a firewall filter that is applied to multiple interfaces, you can name individual counters specific to each interface. These counters enable you to easily maintain statistics on the traffic transiting the different interfaces.

Note: Configuration of interface-specific counters also creates separate instances of any policers you have configured for the same interface. For more information about policers, see Policer Configuration.

To configure interface-specific counters, include the interface-specific statement at the [edit firewall family family-name filter filter-name] hierarchy level:

[edit firewall family filter filter-name]
interface-specific;

Note: The counter name is restricted to 24 bytes. If the renamed counter exceeds this maximum length, the policy framework software might reject it.
