Customizing Wireshark
163
Called SSNs An range of integers representing the ssns for which this association is valid.
User protocol The protocol that is carried over this association
10.15. SMI (MIB and PIB) Modules
If your copy of Wireshark supports libSMI, you can specify a list of MIB and PIB modules here. The
COPS and SNMP dissectors can use them to resolve OIDs.
Module name The name of the module, e.g. IF-MIB.
10.16. SMI (MIB and PIB) Paths
If your copy of Wireshark supports libSMI, you can specify one or more paths to MIB and PIB modules
here.
Directory name A module directory, e.g. /usr/local/snmp/mibs. Wireshark automatically
uses the standard SMI path for your system, so you usually don't have to add
anything here.
10.17. SNMP Enterprise Specific Trap Types
Wireshark uses this table to map specific-trap values to user defined descriptions in a Trap PDU. The
description is shown in the packet details specific-trap element.
This table is handled by an Section 10.7, “User Table” with the following fields.
Enterprise OID The object identifier representing the object generating the trap.
Trap Id An Integer representing the specific-trap code.
Description The description to show in the packet details.
10.18. SNMP users Table
Wireshark uses this table to verify authentication and to decrypt encrypted SNMPv3 packets.
This table is handled by an Section 10.7, “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'.
Privacy protocol Which encryption algorithm to use (either "DES" or "AES").
