11.18. SNMP users Table

Wireshark uses this table to verify authentication and to decrypt encrypted SNMPv3 packets.

This table is handled by an Section 11.7, “User Table” with the following fields.

Engine ID
If given this entry will be used only for packets whose engine id is this. This field takes an hexadecimal string in the form 0102030405.
Username
This is the userName. When a single user has more than one password for different SNMP-engines the first entry to match both is taken, if you need a catch all engine-id (empty) that entry should be the last one.
Authentication model
Which auth model to use (either “MD5” or “SHA1”).
Password
The authentication password. Use \xDD for unprintable characters. An hexadecimal password must be entered as a sequence of \xDD characters. For example the hex password 010203040506 must be entered as \x01\x02\x03\x04\x05\x06. The \ character must be treated as an unprintable character, i.e. it must be entered as \x5C or \x5c.
Privacy protocol
Which encryption algorithm to use (either “DES” or “AES”).
Privacy password
The privacy password. Use \xDD for unprintable characters. An hexadecimal password must be entered as a sequence of \xDD characters. For example the hex password 010203040506 must be entered as \x01\x02\x03\x04\x05\x06. The \ character must be treated as an unprintable character, i.e. it must be entered as \x5C or \x5c.
