This tab lets you view and configure the rate limit mappings for a rate limit port group. Rate limit mappings map a logical rate limit index used by classes of service to an actual physical rate limit you have created in Policy Manager.
Each port group has its own set of index mappings. Policy Manager automatically assigns these index numbers when you configure a class of services's rate limits and transmit queue shapers.
The rate limit mappings tab allows you to do two things:
- Map the index to a different rate for different port groups (edge ports versus inter-switch links). See Creating Class of Service Port Groups
- Map the index to a different rate limit for each port type (8-rate limit, 32-rate limit, 64-rate limit, and 100-rate limit) in a port group. See Advanced Rate Limiting by Port Type.
To access this tab, select a rate limit port group in the left-panel of the Class of Service Configuration window (available from the Policy Manager Edit menu). Then, select the "Show all CoS Components in Tree (Advanced Mode)" option from the Domain Managed CoS Components menu to display the CoS tree in the left panel. Select a rate limit port group in the tree and then select the CoS - Rate Limit Mappings tab in the right panel.

- IRL/ORL Index
- The logical inbound rate limit (IRL) or outbound rate limit (ORL) index number. This index number is specified in a class of service and dictates the rate limiting behavior for incoming packets. For each rate limit port group, use this tab to map the index number to an actual rate limit.
- IRL/ORL Port Type(s)
- The type of ports included in the port group. Port type is based on the number of rate limits the ports support (for example, 8-rate limit ports and 32-rate limit ports).
- Add/Edit Button
- Opens the Add/Edit CoS to Rate Limit Mappings window where you can add or edit rate limit mappings for the rate limit port group
