FIOS ONT Ethernet ----> 3750 Switch 5 interfaces on VLAN2 two of the 5 interfaces tagged to handle VLAN1 and 2 traffic ----> 1921 router WAN interface connected to one of the VLAN2 3750 interfaces, the two tagged interfaces go to two Mac Minis that handle low volume email. The minis have one ethernet interface with WAN traffic on VLAN2, LAN traffic on VLAN1
I would like to move the VLAN2 interfaces from the 3750 Switch to the 1921 Router to have this configuration:
FIOS ONT Ethernet ----> 1921 G0/0 Interface WAN with EHWIC-4G interfaces
Four fixed IP addresses, contiguous addresses but not a subnet, are provided by FIOS and used for:
WAN router traffic on the 1921 port G0/0
WAN email traffic and local LAN traffic for the 2 Mac Minis each with one ethernet interface on the 1921 port g0/0/2 and G0/0/3. These are low volume email servers and they do not route.
Is there a way to configure the 1921 router so that the G0/0 and the EHWIC-4G interfaces G0/0/0 - G0/0/3 work as a switch for the WAN FIOS fixed IP addresses and interfaces G0/0/2 and G0/0/3 are 802.1q tagged and handle traffic for VLAN1 (the LAN) and VLAN2 (the WAN)? G0/0/0 and G0/0/1 would be VLAN2 traffic only. G0/0/2 and G0/0/3 would be tagged for VLAN1 and VLAN2 traffic
On a CISCO 3750 I can configure a group of interfaces to do what I want using these IOS statements:
Well in this case i believe you will be able to configure the EHWIC with same commands as your switch for required roles, however i really doubt that if the onboard port i.e. G0/0 can be configured as layer 2 switchport.
But i still recommend to check if it can be done so use the IOS help (?) at the interafce configuration mode of G0/0 and look for switchport command as it will configure the port as layer 2.
If available you are good to go by configuring the link as access for vlan 2 else you may have to install another EHWIC or need to use a layer 3 link on your router.
Thank you for trying to help me. I've read the links you provided and many more before posting my question. The EHWIC configuration guide is nice, but doesn't address the configuration that I am trying to implement. Table 6 of the EHWIC specification link clearly states that the 1921 router only supports 1 4-port EHWIC. I'm not looking for help in reading CISCO and related web pages.
What I'm hoping to find is somenone that has actually configured a 1921 to pass dot1q traffic on the ehwic ports to both the lan and wan on a 1921 router. If that person exists, then I hope they can share their portion of their config file that shows what to enter to get it to work.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
