column
SNMPv2-SMICounter64
In one IPv6 hop by hop option extension header, it carries a variable
number options. User can screen any one or several options.
When the hop by hop option screen is enabled, the device screens all
IPv6 packets with specific option type.
The attribute counts the number of block IPv6 option type packets.
