Frame Monitor

NOTE

Only available for Fabric OS products.

NOTE

Frame Monitoring is supported in Professional Plus and Enterprise Editions only. It is not supported in the Professional Edition.

Frame monitors count the number of frames transmitted through a port that match specific values in the first 64 bytes of the frame. Since the entire Fibre Channel frame header and many upper protocol (for example, SCSI) headers fall within the first 64 bytes of a frame, frame monitors can detect different types of traffic transmitted through a port. Each frame monitor keeps a timestamp of its last refresh. It also keeps a generation count, which is incremented each time the monitor is cleared.

Frame monitors generate alerts whenever the frame count for a certain frame type crosses the threshold configured for that frame type. You can configure high thresholds for every frame type, specify actions to be taken when the threshold is exceeded, and configure how often the data are sampled.

Virtual Fabrics considerations: You can assign frame monitors to ports in a logical switch. If a port is moved from one logical switch to another, however, all monitors that were assigned to the port are cleared in the new logical switch.

Trunking considerations: For trunked ports, the frame monitor is configured on the trunk master.
