Configuring Access Control Lists

interface. Changes  to an existing route-map associated with an interface (or 

to the associated ACLs) do not take effect until the route-map is reapplied to 

the interface. 

An ACL rule contains match and action attributes. For example, an ACL rule 

may have a match clause on the source IP address and action attributes 

independent of PBR, such as queue assignment, as shown below:

ip access-list example-1

permit ip 1.1.1.1 0.0.0.255 any assign-queue 2 

permit every

exit

Actions specified in the “set” clauses of a route-map utilize the hardware 

entries of the corresponding ACL. This sharing does not consume additional 

hardware resources, as DNOS supports multiple actions in an ACL rule. 

However, if conflicting actions are specified, an error is thrown.

Policy Based Routing does not affect locally generated packets, i.e. packets 

generated by protocols running on the switch.

Once a route-map has been applied to an interface (e.g., using the ip policy 

route-map command), changes to the ACL or route-map do not take effect 

on the interface until one of the following activities is completed: 

• The route-map is removed from the interface and reapplied.
• The router is reloaded.

See "Policy Based Routing Examples" on page 640.
