ptopoConfigMaxHoldTime 1.3.6.1.2.1.79.1.3.2

This object specifies the desired time interval for which an agent will maintain dynamic ptopoConnEntries. After the specified number of seconds since the last time an entry was verified, in the absence of new verification (e.g., receipt of a topology protocol message), the agent shall remove the entry. Note that entries may not always be removed immediately, but may possibly be removed at periodic garbage collection intervals. This object only affects dynamic ptopoConnEntries, i.e. for which ptopoConnIsStatic equals 'false(2)'. Static entries are not aged out. Note that dynamic ptopoConnEntries may also be removed by the agent due to the expired timeliness of learned topology information (e.g., timeliness interval for a remote port expires). The actual age-out interval for a given entry is defined by the following formula: age-out-time = min(ptopoConfigMaxHoldTime, <entry-specific hold-time>) where <entry-specific hold-time> is determined by the discovery algorithm, and may be different for each entry.
