Unterschied zwischen VTP und DTP

[xyCruiseryx]

Moin ich brauche mal eine kurze Definitionshilfe vom Begriff: VTP und DTP

VTP: Vlan trunking protokoll: Mitteilen der Vlan Informationen (vom Server) an alle Clients


DTP: Dynamic trunking protokoll: Austomatisches Aushandeln von "MLTs oder Etherchannels auf jedem Port. Default ist DTP eingeschaltet.

Status: on, desirable, auto

Ist das so IO ????

kann mir einer den Unterschied zwischen den 3 Staus optionen erklären. ich hab noch nie was mit dem DTP zutun gehabt.

Hola,

das sollte helfen:

Trunking Mode Characteristics

COS = on
IOS = mode trunk

Trunking is on for these links. They will also send DTP signals
that attempt to initiate a trunk with the other side. This will
form a trunk with other ports in the states on, auto, or
desirable that are running DTP. A port that is in on
mode always tags frames sent out the port.
---------------------------------------------------------------------------------------

COS = desirable
IOS = mode dynamic desirable

These links would like to become trunk links and will send
DTP signals that attempt to initiate a trunk. They will only
become trunk links if the other side responds to the DTP
signal. This will form a trunk with other ports in the states on,
auto, or desirable that are running DTP. This is the default
mode for the 6000 running Supervisor IOS.
--------------------------------------------------------------------------------------

COS = auto
IOS = mode dynamic auto

These links will only become trunk links if they receive a DTP
signal from a link that is already trunking or desires to trunk.
This will only form a trunk with other ports in the states on or
desirable. This is the default mode for COS switches.

----------------------------------------------------------------------------------------

COS = off
IOS = no switchport mode trunk

This option sets trunking and DTP capabilities off. This is the
recommended setting for any access port because it will
prevent any dynamic establishments of trunk links.
-----------------------------------------------------------------------------------------

If you want to enable trunking and not send any DTP signaling, use the option
nonegotiate for switches that support that function. If you want to disable trunking
completely, use the off option for a COS switch or the no switchport mode trunk
command on an IOS switch.

Besten Dank dafür ab welcher IOS Version wird die Funktion unterstützt ? Welche Geräte können das heute schon ?
