Trunk and Access Ports - Whats the Difference? 

for real, i had problems understanding trunks ,now im good

Dude needs to come back!

I used the Windows Terminal, you should be able to search for it in the Windows store.

@@lezunetworking thanks :)

If you were only to do that in this instance spanning tree would block the port as inconsistent. If you were to, however, set the native vlan on the trunk port to match the access port it would technically work as the voice vlan = tagged and the access vlan = untagged so the switch would know what belongs to each vlan.

@@lezunetworking good call, both would try to be designated forwarding...turn off STP? Lol

In this scenario, they were static ip addresses. In the case of a router doing DHCP, whatever access port the router is connected to, the VLAN configured to that port will come into play. The router will give out ip addresses to the machines connected to the other ports that are also configured to the same VLAN as the Router's port.

I would imagine that most switches that support VLANs would support VLAN tagging in some way. If you want a cheap switch to play around with, look into used Cisco equipment such as a 3750 switch.

@@lezunetworking thank you so much!!

Previously, Cisco utilized both ISL and dot1q as means to tag frames across a trunk. ISL (Inter-Switch Link) is a Cisco proprietary protocol that is no longer used but was the default on older switches. Dot1q is what other vendors use and is a preferred method to encapsulate a trunk, we just need to specify it on some older models of Cisco switches.

As long as you turn on "ip routing" and the SVI or interface VLANs are on the same switch you will be able to ping between VLANs (if from PC it must have correct default gateway set). If the SVIs were on different switches you would need to set up static or dynamic routing to ping between the VLANs.

As long as you turn on "ip routing", given the switch is layer 3 capable, and SVI or interface VLANs are on the same switch you will be able to ping between VLANs (if from PC it must have correct default gateway set). If the SVIs were on different switches you would need to set up static or dynamic routing to ping between the VLANs.
