I have a new SRW208G switch and what I want to do seems very simple but so far I am unable to figure out how to do it.
- DSL Router connected to g1.
- I want ports e1 through e7 to be "normal" LAN, i.e. devices connected to these ports can all connect to each other and to g1.
- I want port e8 to be able to communicate ONLY with the DSL router on g1.
It seems that PVE should be the simplest way to set this up but so far everything I've tried results in no communication on e8.
Can someone please provide detailed steps for this seemingly simple configuration? I would like to avoid tagging if possible.

Basically, you need to create VLAN on the switch. If I'm not mistaken, the
default VLAN on the router is VLAN 1 (also known as Native VLAN). If you
connect a certain router to the switch, all traffic will pass-through because
all ports are part of the native VLAN. From your given scenario, you
wantedport e8 to communicate only to your DSL router. It is possible to
accomplish if you will create another VLAN on the switch.I think port 1 is
the default management port of the switch.
1.If you would like to use port e8 to communicate to the DSL router, then
it should be part of the native VLAN or VLAN 1. If your router is just a
typical router and not a multi-layer router then it will communicate only to
the native VLAN. So, if port#1 is a management port, then you may
include this to VLAN 1. Make sure g1 is part of the Native VLAN also.
2. The rest of the ports will be on VLAN 2. Once VLAN is created, members
of VLAN1 will no longer communicate to the members of the VLAN 2 or the
other way around. Only computers connected to the VLAN1 are capable to
connect to the Internet.
3. If in case you'd like to share your Internet connection to all VLANs
created on the switch, you should have used a multi-layer router (this
router is capable for inter-VLAN - high-end type of router).

As suggested by gv, I re-posted my question at https://www.myciscocommunity.com/community/smallbi
With help there, I was able to solve my problem.

dfever, I was able to accomplish my requirement without the need for a level 3 router using the private vlan edge feature of the SRW208G.
Thanks to you both for your suggestions.
