Hi
I have a 750G ,I want make a trunk port in interface Ethernet 1 and make 2 access port in interface Ethernet 2 and 3 each one must be in separate vlan
The Ethernet port 1 is connect to a cisco trunk port,I want put the Ethernet 2 vlan 2 and
Ethernet 3 in vlan 3

any idea is there for this
regards

The 750G is a router, not a switch, so it is fundamentally ill-suited for this.

That said, you would create the two VLAN interfaces tied to ether1 and bridge one VLAN interface to ether2 and the other to ether3. If the router is to act as a layer 3 hop for either VLAN the IP address would go on the bridge interface.

Really it would be better to use a switch for this.

Tanks Dude
It's worked

I've never used the 750G, does it have support for the switch chip?

It does. It might be possible to use it for this purpose, but I don't know how.
