Port-level Rate Limiting Service Configuration
31.5 PORT-LEVEL RATE LIMITING
Note Port-level rate limiting is not yet supported by Service.
Use a port-level rate limiting policy if incoming or outgoing traffic on a particular port needs to be rate limited. Unlike
other types of rate limiting policies, do not specify an ACL when defining this type of policy. Port-level rate limiting
policies do not need to be applied to an interface and they take effect when they are created.
To configure port-level rate limiting policies for input ports, enable the aggregate rate limiting mode on the line card
Do not enable the aggregate rate limiting mode to configure a policy to rate limit outgoing traffic. Configure port-level
rate limiting policies on output ports in either the per-flow or aggregate rate limiting modes.
Note For output port policies, the only action to specify if traffic exceeds the specified
rate is to drop packets.
When using output port-level policies, all types of outgoing traffic will be rate limited, including control traffic. To
prevent the rate limiting of control traffic, use the rate-limit port-level slot ignore-control-priority
command.
31.6 SERVICE CONFIGURATION EXAMPLES
31.6.1 Applying a Service to Multiple Servers
The configuration example in Figure31 -2 shows how easily a network can be configured for aggregate rate limiting
using a service aggregate1. S1 through S4 can be rate limited using one service applied to QAInterface1.
