Device Connection Control policies 7 Deleting a DCC policy 1. Connect to the switch and log in using an account with admin permissions, or an account with OM permissions for the Security RBAC class of commands. 2. Enter the secPolicyDelete command. Example of deleting stale DCC policies switch:admin> secpolicydelete ALL_STALE_DCC_POLICY About to clear all STALE DCC policies ARE YOU SURE (yes, y, no, n): [no] y DCC policy behavior with Fabric-Assigned PWWNs A DCC policy check is always performed for the physical port WWN of a device when the HBA has established that the device is attempting a normal FLOGI and has both a fabric-assigned port WWN (FA-PWWN) and a physical port WWN. DCC policies created with FA-PWWNs will result in the disabling of FA-PWWN assigned ports on subsequent FLOGI. It is therefore recommended to create policies with the physical PWWN DCC policies created with the lock down feature result in DCC policies with FA-PWWNs. It is therefore recommended to avoid using the lock down feature in fabrics that are using FA-PWWNs. A DCC policy created with a device WWN for a specific port allows the device to log in only on the same port. The same device will not be allowed to log in on a different port. For devices that log in across an AG, the policy should be created with all the NPIV ports, so even if failover occurs the device will be allowed to log in on a different NPIV port. Table 33 lists the behavior of the DCC policy with FA-PWWNs in the fabric when the DCC policy is created using lockdown support.

Traffic will not be disrupted. Ports will be disabled for security violation.2 Ports will come up without security issues. Ports will come up without any security issues. 1. Indicates a security concern, because devices that are logged in with FA-PWWNs will not be disabled after activation of DCC policies that are created with FA-PWWNs. This is done to avoid disturbing any existing management. 2. Any disruption in the port will disable the port for a security violation. As the traffic is already disrupted for this port, you must enforce the DCC policy for a physical device WWN; otherwise, the device will not be allowed to login again.
