RFC2863 Interface MIB (64 bit counters support)
The support for the following entries was added in the interface table: 
ifHCInOctets, ifHCInUcastPkts, ifHCOutOctets and ifHCOutUcastPkts. These 
counters already existed and were extended from Counter32 to Counter64. 
VPN Router MIB
This MIB contains VPN Router proprietary MIB data. For instance the ping MIB 
is contained in this file. The ping MIB, through an SNMP GET REQUEST, 
causes the VPN Router to ping another device and get statistics based on the 
results of the ping. For instance sending a PDU specifying 
pingAverageTime.192.32.250.248.4.4076 sends four pings, of 4076 bytes, to 
address 192.32.250.248. (It actually sends five pings. One ping is sent by itself so 
that if the device being pinged is the other end of a Branch Office tunnel, it 
ensures that the tunnel is brought up before trying to send pings through the 
tunnel. This ping is not counted in the statistics.) The object returns the values of:
-2 Invalid parameter(indices).
-1 No reply.
0 Less than 16ms average time.
>0 The average time.
The objects and their parameters(indices) are:
pingAverageTime - returns the average ping time for the set of 
specified pings.
pingPercentLoss - returns the percentage of loss.
The first index is the IP address to ping. The second index is the number of pings, 
if this is not specified or is an invalid value it defaults to 3. The third index is the 
size of the ping request. If it is not specified or is an invalid value then it defaults 
to 1024.
VPN Router MIB provides trap acknowledgement.
