How to VLAN using switchports?

Jump to solution

I can't seem to figure out how to set up multiple VLANs on a single switchport, here's the configuration I've come up with:

ip dhcp pool "VLAN1"

  network 192.168.1.0 255.255.255.0

  default-router 192.168.1.1

ip dhcp pool "VLAN2"

  network 192.168.2.0 255.255.255.0

  default-router 192.168.2.1

ip dhcp pool "VLAN3"

  network 192.168.3.0 255.255.255.0

  default-router 192.168.3.1

interface eth 0/1

  ip address dhcp

  no shutdown

interface eth 0/2

  ip address dhcp

  no shutdown

interface switchport 0/1

  no shutdown

  switchport mode trunk

  switchport trunk allowed vlan 1-3

interface vlan 1

  ip address  192.168.1.1  255.255.255.0

  no shutdown

interface vlan 2

  ip address  192.168.2.1  255.255.255.0

  no shutdown

interface vlan 3

  ip address  192.168.3.1  255.255.255.0

  no shutdown

It appears to be working somewhat, I always get the Native VLAN information. I have a Netgear switch with the following setup:

VLAN 1:

Untagged: 1-24

VLAN 2:

Tagged: 1

Untagged: 2-12

VLAN 3:
Tagged: 1

Untagged: 13-24

I'm coming from a Cisco background, which I can do this setup very easily with Cisco equipment, but for whatever reason I'm having difficulties with getting it working properly on the Adtran/Netgear set up.

Thank you for your help!

Hi python09:

Thanks for posting your question in the Support Community!  I think you're very close with this configuration.  I don't see any problem with the 3448 config.  The Netgear switch appears to have VLAN 1 untagged for all 24 ports, but VLANs 2 and 3 are also untagged for their respective ranges.  I recommend using Netgear's "advanced" or 802.1Q configuration options.  If I recall correctly, you need to (a) set the default VLAN membership for each port (VLAN 1 for port 1; VLAN 2 for ports 2-12; VLAN 3 for ports 13-24).  And (b) setup VLAN 1 to be untagged only on the trunk port--port 1--and make it tagged for 2-24.  Leave VLAN 2 untagged for 2-12, and VLAN 3 untagged for 13-24, as you have it listed.

Best,

Chris
