Rate Limiting
Like an access list, a rate limit includes a list of values to compare with the incoming packets and an
action to take for packets that match. Additionally, a rate limit specifies an action to take when
matching packets arrive at a rate above the limit you set. When you create a rate limit, you must specify
a value for each of the fields that make up the access mask used by the list. Unlike an access list, a rate
limit can only be applied to a single port. Each port has its own rate limit defined separately.
Each entry that makes up a rate limit contains a unique name and specifies a previously created access
mask. As Figure 78 shows, the next section allows you configure an access list, a rate limit, or both. Use
the pull-down menus to select the type of listing option, a mask, and the ports. Press the Submit
button, when your configuration is complete.
Figure 78: Access List Configuration (2 of 2)
As shown in Figure 79, the final section of this window allows you to create, modify, or delete an access
list. You can also create, modify or reset a rate limit. See the previous section for definitions of these
fields.
