usrVHASecurTimeDrift
Module: USR-VHA-MIB
OID (symbolic): USR-VHA-MIB::usrVHASecurTimeDrift
OID (numeric): 1.3.6.1.4.1.429.4.84.5.1.1.5
Node type: OBJECT-TYPE
Type: Integer32
Access: read-write
Description: The value represents how close the timestamp, contained in the Identification information element of the Registration Request or the Registration Acknowledge message, should be to the PDSN's time of day clock. This time tolerance is used in conjunction with timestamp replay protection against replay attacks.
What is usrVHASecurTimeDrift?
It sets how closely (0-255, likely seconds) the timestamp in a Registration Request or Acknowledge message must match the PDSN's own time-of-day clock, used for replay-attack protection. An admin would widen this tolerance somewhat if the PCF and PDSN clocks aren't perfectly synchronized, at the cost of a slightly weaker replay defense.
