### Description

```asn1
ptopoConfigMaxHoldTime OBJECT-TYPE
SYNTAX Integer32 (1..2147483647)
UNITS "seconds"
MAX-ACCESS read-write
STATUS current
DESCRIPTION
"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."
DEFVAL {300}
