A ping request entry.

A management station wishing to create an entry should first generate a pseudo-random serial number to be used as the index to this sparse table. It must also create in the same PDU the associated instance of the address object. It should also modify in the same PDU the default values for the other configuration objects if the defaults are not appropriate.

Once the sequence completes, the management station should retrieve the values of the status objects of interest, and should then delete the entry. In order to prevent old entries from clogging the table, entries will be aged out, but an entry will never be deleted within 5 minutes of completing.
