Vlan Tagging at Access Port in Switch

view story
linux-howto

http://serverfault.com – I'm Confused from the fact that Vlan tagging is done at access port and trunk port always gets tagged packets (until its case of native vlan).But I still believe in other fact which says tagging happen only when a frame hit the trunk port which means trunk port gets untagged frame and tagging is not possible at access port. Would like to know where actually this tagging happens ? and also which command we can use to encapsulate 802.1q protocol to access port ? The way we do at trunk port is switchport trunk encapsulation dot1q Is the above command applicable for access mode also? (HowTos)

Stories similar to Vlan Tagging at Access Port in Switch

Good day,

I need to configure two vlan on an AP connected with a Dell PowerConnect 2848.

I have the following scenario:

EX2200 Switch whit

ge-0/0/6 set as an access port on VLAN 80 ge-0/0/0 set as a trunk port connected to a catalyst switch and various vlans allowed to pass includin vlan 80

On the Catalyst Switch.

port #3 set up as a trunk port that receives traffic from the EX switch. port 42 is set up also as a trunk port that connects to a cisco router. Port #46 is where t

When you try to configure trunk port you might see following error An interface whose trunk encapsulation is Auto can not be configured to trunk mode

To fix this you need set encapsulation to 802.1q using the following command conf t int gi4/10 switchport trunk encapsulation dot1q This should fix your issue

In order to migrate to a new rack inside the datacenter I have to replicate the VLAN setup between a Cisco Switch and a Dell PowerConnect Swithch.

On the Dell Switch I have 2 VLANs :

vlan 10 : WAN vlan 20 : MGMT

On the Cisco Switch i have created the same VLANs and set up different port range

vlan10 : Ports 1-12 vlan20 : Ports 13-24

Like this example:

interface gigabitethernet2

I am a bit new to vlan, so forgive me if I ask noob question.

I am trying to setup a vlan on my netgear switch (GS105E). I want to create 2 separated networks and I want both of them have internet access.

My setup is

Modem connect to router WRT54G (with dd-wrt) connect to netgear switch

I have configured port 1 and port 5 as vlan1 and port 2 to port 4 as vlan2.

I have 6 Juniper switches (EX - 2200) connected to each other as shown in the network topology.

I have two PC's that I am using

PC1 - (used for configuring the 6 switches via minicom)

PC2 - to monitor the traffic between the switches via the Ports that are marked with arrows in the diagram.

STEP 1:

I create a new vlan On Switch 3 (SW3) that includes Port 12 and Port 22.

HP 1810-48G Switch (J9660A) 33 weeks 19 hours ago

I am setting up 4 Vlan.Port 1 is my management port and belongs to Vlan 1 Port 2-12 is Vlan 2. Port 13-24 is Vlan 3. Port 25-36 Vlan 4. There is 3 different companies that uses Vlan 2-4 but i want them to share one printer. The printer is connected to port 48.

Will this work or do i need to have to install a router?
