Application of Rules or Policies

When the software makes the final determination of which default or user-configured role applies to the identity, the policies and rules configured for that role are applied to the port to which the identity connected. This feature supports up to eight policies and dynamic ACL (Access Control List) rules per role (eight total).

When a dynamic ACL or policy is added to a role, it is immediately installed for all identities mapped to that role. Effective configuration of the dynamic ACLs and policies will ensure that intruders are avoided at the port of entry on the edge switch, thereby reducing noise in the network.

Note

The identity management feature supports wide key ACLs, which allow you to create many more match conditions for each ACL. For more information, see Wide Key ACLs.

The dynamic rules or policies that are installed for an identity, as determined by its role, are customized for that identity by inserting the MAC or IP address of the identity as the source address in the ACL rules. In ExtremeXOS release 12.5, identity manager inserted the IP address of the identity in all the ACL rules to be installed for that identity. Beginning with release 12.6, identity manager can insert either the MAC address or the IP address of the identity in all the ACL rules to be installed for that identity. By default, the MAC address of the identity is used to install the ACLs. Every network entity has a MAC address, but not all network devices have an IP address, so we recommend that you use the default configuration to install ACLs for network entities based on the source MAC address.
