- Sub-optimal performance detected - network capacity might be significantly impacted
- The total capacity measured in the network path is in a range that historically has been proven to be sub-optimal. Typically, minor configuration changes can greatly improve performance.
- If the total capacity is deemed to be acceptable, no action is required. If the total capacity is below expectations, and one or more diagnostic messages has been generated, take the recommended course of action for each message. Start with the diagnostic message with the highest certainty value. Additional information and suggested courses of action for different capacity measurements can be found in the table below.
- Total capacity is the highest transmission rate that you can achieve between sender and receiver when no other traffic is on the line; you can read more about it here. In this particular case, the total capacity measurement corresponds to a value that historically has been proven to be sub-optimal. The table below describes the typical causes of sub-optimal performance for a given range of total capacity.
Possible secondary messages
* ‘May be due to use of half-duplex or mixture of half- and full-duplex modes’
* ‘May be due to sub-standard or misconfigured NIC or driver’
* ‘May be due to limiting in the mid-path or a slow-path response at target host’
* ‘May be due to a slow-path response at target host’
* ‘May be due to improper QoS (802.1p QoS) configuration resulting in VLAN tagging mismatch’
