Limiting Traffic Rate

324 Enterasys Xpedition User Reference Manual

To enable aggregate rate limiting mode on the XP, enter the following command in

Configure mode:

To change the rate limiting mode on the XP back to per-flow mode, negate the above

command.

Per-Flow Rate Limiting

Use a per-flow rate limiting policy if an individual traffic flow needs to be limited to a

particular rate. A single per-flow rate limiting policy can have multiple ACLs to define

different traffic profiles and traffic rate limitations. When there are multiple traffic

profiles, a sequence number is used to identify the order in which the profiles are applied.

Note: Per-flow rate limiting is enabled on the XP by default. If you enable aggregate rate

limiting on the XP, you cannot configure per-flow rate limiting policies.

To define a per-flow rate limit policy and apply the policy to an interface, enter the

following commands in Configure mode:

Note: You cannot use non-IP ACLs for per-flow rate limit policies.

Port Rate Limiting

Use a port rate limiting policy if incoming or outgoing traffic on a particular port needs to

be rate limited. Unlike other types of rate limiting policies, you do not specify an ACL

when defining this type of policy. Port rate limiting policies do not need to be applied to

an interface and take effect when they are created.

To configure port rate limiting policies for input ports, you must first enable aggregate

rate limiting mode on the XP (see Rate Limiting Modes on page 323). You do not need to

enable aggregate rate limiting mode to configure a policy to limit outgoing traffic on a port.

You can configure port-level rate limiting policies on output ports in either per-flow or

aggregate rate limiting mode.
