basic vlan question

[ducvu2005]

got a question for the experts: I have a router which is directly connecting to a switchport (3524s), need to config this port belonged to Vlan 100 and untagged. How do I config switchport "untagged" ? thanks for all help.

Hi,

Just do the following

conf t

int fa 0/x --> where x is the port number

switchport mode access

switchport access vlan 100

This will make you port as untagged and an access port for vlan 100.

Please revert if you have any other requirement.

Dear Amit,

Thanks for quick reply so if I wanted to tag the port what should I do then ? just explore a bit more.

Hi Ducvu,

Bydefault 3500XL switches does not tagg vlans till the time you specifically configure as a trunk port. Even if you configure trunk ports you can use native keyword for vlan for which you want to send untagged traffic.

Also bydefault the ports are accses ports and falls to vlan 1 if you just change the port to acess vlan 100 it will start sending vlan 100 traffic and obviously untagged.

dear Ankur,

In this case do I have to config anything on the router side in order to accomplish the requirements : belong to vlan 100 and untagged ? also the only way to tag traffics is to config trunk port ? thanks for help.
