portThConfig command procedures 7 • Areas: Receive (Rx) Performance, Transmit (Tx) Performance Rx and Tx Performance areas are used to monitor the bandwidth utilization of the device ports in the fabric. Set the high boundary to 85 percent and the alarms to Above and In-Between conditions. The same levels should be set on both Host and storage device ports. NOTE With the increased use of virtual environments, alerts from device ports are increasing more than ever in the past. This provides a good gauge as to the overall bandwidth requirement changes and utilization and could indicate that additional ISL trunks are required. • Area: Link Reset The goal of the Link Reset area is to avoid excessive link resets which can cause back pressure in the fabric. The Link Reset area is new; therefore, recommended settings are not available. Keep the default settings, monitor the results, and adjust your settings accordingly. • Area: Class 3 (C3) Discards Unlike the other areas, take a conservative approach for the C3 Discards area. Use the default settings and configure the alarms for Above. The goal is to locate issues with the device or its infrastructure, so monitor the data to help isolate issues. Port fencing is one of the recommended solutions for isolating issues. • Area: Trunk Utilization The Trunk Utilization area is new; therefore, recommended settings are not yet available. Use the default settings, monitor the results, and adjust your settings accordingly. • Areas: Primitive Sequence Protocol Error, State Changes These areas are not used for monitoring; therefore, leave the default alarm settings at 0. FOP_Port and FCU_Port subclass default settings Table 18 provides default settings for areas in the FOP_Port and FCU_Port subclasses. Port fencing can only be enabled or disabled for the following areas for the FOP_Port and FCU_Port class: • Link Failure Count • Loss of Synchronization Count • Primitive Sequence Protocol Error • Invalid Transmission Word • Invalid CRC Count • Class 3 Discards Fabric Watch Administrator's Guide 65 53-1002752-01

Areas: Receive (Rx) Performance, Transmit (Tx) Performance
Rx and Tx Performance areas are used to monitor the bandwidth utilization of the device ports
in the fabric. Set the high boundary to 85 percent and the alarms to Above and In-Between
conditions. The same levels should be set on both Host and storage device ports.
NOTE
With the increased use of virtual environments, alerts from device ports are increasing more
than ever in the past. This provides a good gauge as to the overall bandwidth requirement
changes and utilization and could indicate that additional ISL trunks are required.
•
Area: Link Reset
The goal of the Link Reset area is to avoid excessive link resets which can cause back pressure
in the fabric. The Link Reset area is new; therefore, recommended settings are not available.
Keep the default settings, monitor the results, and adjust your settings accordingly.
•
Area: Class 3 (C3) Discards
Unlike the other areas, take a conservative approach for the C3 Discards area. Use the default
settings and configure the alarms for Above. The goal is to locate issues with the device or its
infrastructure, so monitor the data to help isolate issues. Port fencing is one of the
recommended solutions for isolating issues.
•
Area: Trunk Utilization
The Trunk Utilization area is new; therefore, recommended settings are not yet available. Use
the default settings, monitor the results, and adjust your settings accordingly.
•
Areas: Primitive Sequence Protocol Error, State Changes
These areas are not used for monitoring; therefore, leave the default alarm settings at 0.
FOP_Port and FCU_Port subclass default settings
Table 18
provides default settings for areas in the FOP_Port and FCU_Port subclasses.
Port fencing can only be enabled or disabled for the following areas for the FOP_Port and FCU_Port
class:
•
Link Failure Count
•
Loss of Synchronization Count
•
Primitive Sequence Protocol Error
•
Invalid Transmission Word
•
Invalid CRC Count
•
Class 3 Discards
