Policy monitor overview 36

Some devices can function as both initiator and target. If the application finds this type of device as one of the active zone members, this device port is treated as both initiator and target:

-Target (storage port) — The application counts the number of initiator ports zoned to this storage port.

-Initiator — The application counts this device as an initiator port for other storage ports in the same zone.

Rule Violation Fix — If the policy monitor report shows a violation, the Administrator must make sure the initiator port limit is under the recommended number.

•Check zones that do not contain any online member — This fabric policy monitor enables you to identify zones in which all zone members are offline.

NOTE

The application does not count end devices which are missing from the fabric and D,PI zone members (online or offline) as online zone members. The application only counts zones with online WWN members as online zone members.

Rule Violation Fix — If the policy monitor report shows a violation, you can use the Zoning dialog box (Configure > Zoning > Fabric) to bring the devices back online (refer to “Zoning” on page 637).

For example, if you use the policy monitor to determine when all WWN members in a zone are offline, you can fix the violation through the Zoning dialog box by locating the target fabric and bringing the devices back online.

•Check that all profiles are the same on each RBridge in an Ethernet fabric — This fabric policy monitor enables you to determine if all RBridge profiles in a Ethernet fabric are the same. The first check is to determine if the name matches. If the name matches, policy monitor checks the other profile content (such as VLAN, QoS, and Security), and then the MAC associations.

A port profile is a collection of network policies supported by the switch. By configuring port profiles on the VDX switch, the virtual machine (VM) that is configured on the virtual network interface card (vNIC) can migrate to any other port on that switch, but still retain the same network policies.

Use this check during VM migration to make sure that the migrated VM behaves the same way on the next host.

Rule Violation Fix — If the policy monitor report shows a violation, compare the port profiles (refer to “Comparing port profiles” on page 437) to find the mismatches and then fix the discrepancies.

Switch and router policy monitors

Switch and router policy monitors enable you to set the following policy monitors on switches and routers.
