With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
nhrpCacheHoldingTimeValid
nhrp Cache Holding Time Valid
True(1) is returned if the value of 'nhrpCacheType' is not 'administrativelyAdded'. Since the value of 'nhrpCacheType' was not configured by a user, the value of 'nhrpCacheHoldingTime' is considered valid. In other words, the value of 'nhrpCacheHoldingTime' represents the Holding Time for the cache Entry. If 'nhrpCacheType has been configured by a user, (i.e. the value of 'nhrpCacheType' is 'administrativelyAdded') then false(2) will be returned. This indicates that the value of 'nhrpCacheHoldingTime' is undefined because this row could possibly be backed up in nonvolatile storage.
