TABLE 20 Health-check policy statistics

Field Description

Sent The number of health-check packets sent by bound health-check policies.

Received The number of replies received. A received reply results in a true condition.

NOTE: Since the Brocade Virtual ADX retries a health check if a reply is not received, a higher

sent count than receive count does not necessarily indicate a problem.

Invalid Replies The number of replies that were received that had an invalid ID. The Brocade Virtual ADX is

sometimes able to resolve an invalid ID. If the Brocade Virtual ADX cannot resolve the invalid

ID, the device drops the reply and increments the Dropped Replies counter.

Dropped Replies The number of replies that the Brocade Virtual ADX dropped.
