Unterschied zwischen VTP und DTP

[xyCruiseryx 10]

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 ?
