UC520 VLAN on WAN Port

[ReidJones]

I have a UC520 which I'm trying to configure.  We are switching to a new ISP who requires that the WAN (FE 0/0) port be tagged with VLAN 35 and then the PPPOE dialer (Dialer2) connected to VLAN35.  How should I go about setting this up.

Thanks!

Hi,

Try the following

interface FastEthernet0/0
 no ip address
 duplex auto
 speed auto
!
interface FastEthernet0/0.35
 encapsulation dot1Q 35
 pppoe enable
 pppoe-client dial-pool-number 1
!
interface Dialer2
 ip address negotiated
 encapsulation ppp
 dialer pool 1
 ppp chap hostname <username>
 ppp chap password 0 <password>
 !
 ip route 0.0.0.0 0.0.0.0 dialer2

Thanks for the help.  That should have done the trick but I'm now left with a new problem.

We have our fiber line coming in from the ISP, it goes to a TP-Link MC220L fiber converter, then over a CAT6 cable to our UC520.  As it turns out, the MC220L only works with GigE, which the UC520 doesn't support.  I do have a SG300 switch, however I'm not sure if its possible to somehow run the MC220L --> SG300 --> UC520.  Any thoughts?

Hi,

In theory this should work although it’s not something that I have implemented before.

As the PPP messages are carried over Ethernet, all you need to ensure is that the UC520 and ISP connection are able to communicate at L2. It shouldn’t matter if you have media convertors or other switches in the path.

Please test and let me know how you get on
