Simple Network Management Protocol (SNMP)

XXX - add a brief SNMP description here

History

XXX - add a brief description of SNMP history

Protocol dependencies

  • ["UDP"]: Typically, SNMP uses ["UDP"] as its transport protocol. The well known UDP port for SNMP traffic is 161/162.

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).

Ethereal

The SNMP dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Ethereal features where appropriate, like special statistics of this protocol.

Preference Settings

(XXX add links to preference settings affecting how SNMP is dissected).

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Ethereal can open gzipped files automatically.

Display Filter

A complete list of SNMP display filter fields can be found in the [http://www.ethereal.com/docs/dfref/s/snmp.html display filter reference]

  • Show only the SNMP based traffic:

     snmp 

Capture Filter

You cannot directly filter SNMP protocols while capturing. However, if you know the ["UDP"] ports used (see above), you can filter on that ones.

SGMP (an ancestor of SNMP):

SNMPv1

SNMPv2

SNMPv2 (Community based)

SNMPv3
