Folks, I know that this forum is maybe not the best place to ask about this, but I would be very pleased if you could help me, please...

I'm analyzing the configuration of an old L2 managed switch that holds the VLAN setup of an enterprise network. And this is not exactly my area of expertise..

Anyway... I have to setup another managed switch to replace this old one...

The "new" one is a Dlink Giga Express DGS 1224T and the old one is a Planet WGSW 2402..

As I have to replace the old switch, I'm trying to get all it's configuration to the other switch... My doubt is that there is a tagged/untagged configuration at all ports on the old switch.. And I find no similar configuration on the ports at the new switch... Do anyone knows what mean tagged or untagged, and why there is a switch who has this option and another that doesn't have?

To help, I took some screenshots of the "old" switch where the tagged/untagged option appears... (we use two VLANs)..

Thanx pretty much dudes... Any from you help is welcome!

Not really that sure what question you're asking, but it looks like port 1 is an uplink with both those vlans tagged on the single connection. So either you need a new L2 switch with vlan tagging support (802.1q) or replace that single port with two uplinked connections without tagging.

thanx for the answer Chris... but why the new switch doesn't have this "tagged/untagged" option? I think both supports 802.1q... do you know?

Different manufacturers refer to standardizd functionality using different terminology, just to make life easy for us networking types!

Nortel used to call a port tagged or untagged, where cisco says a port is a trunk or an access port. Other manufacturers say "Uplink port" and "member port" They mean the same thing. If you are sending frames onto a port complete with an 802.1q header tag then the port is "tagged" or a "trunk". The device at the other end needs to be able to understand these tags to be able to sort frames into their respective VLANs. Servers and routers can be configured to understand VLAN tags, but more normally they are used to interconnect separate VLANs over common fibres between switches i.e. a trunk

So you need to work out what the terminology is that your manufacturer uses to refer to 802.1q trunking or tagging and enable it on both devices.

hi gustavo,

from the picture you've provided us - yes its a managed switch - and of course as an open standard vlan is in 802.1q encapsulation.
being untagged means the port belong to the default vlan1,
and the tagged could belong to any specific vlan - like vlan83/internet nova & vlan70/corp of yours.

not neccesarily its an uplink/trunking or access.

so if you want to move its config - just create those vlan70 & vlan83 on your new switch (dlink) so its really depends on your new switch capability (whether its a manageable one and could carry specific vlan tagging & vlan ID).

HTH.
