Then the answer is no. You can not have two VLAN's on one port.

Hello ammadeyy2020,

Yes multiple VLANS can run on one port - if that port is "Untagged" basically you configure it as a trunk post (A trunk can carry any VLAN tagged traffic), once a port is "tagged" to one vlan it only caries traffic for that VLAN


It is possible in Procurve switches (the ones I work with). it is called tagged VLANs. Try to look in that direction for your switch. Sorry for not being able to help you further

On the 3548 side, designate the port connected to the router as a trunk port.

On the 1701 side, you'll also create a trunk.

You can use ISL or 802.1q as your trunking protocol. I'm using ISL in the example below.

int f0/1
 switchport trunk encapsulation isl
 switchport mode trunk
int f0.1
 encapsulation isl 1
 ip address
int f0.2
 encapsulation isl 2
 ip address
int f0
 no shut
