ROAS and Switch Ports

James Saunders

Hi All,

Very quick question, if I am using a router on a stick setup but on the same router I have switch ports via a HWIC card installed, is it possible to make devices I plug in to them ports land in the same network as traffic coming in my sub-interfaces.

 

interface GigabitEthernet0/0
  no ip address
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 duplex full
 speed 1000
 no mop enabled
!
interface GigabitEthernet0/0.10
 encapsulation dot1Q 10
 ip address 192.168.1.1 255.255.255.192
 ip access-group IN_OUT_VLAN10 in
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly in
!
interface GigabitEthernet0/0.20
 encapsulation dot1Q 20
 ip address 192.168.1.65 255.255.255.192
 ip access-group IN_OUT_VLAN20 in
 ip access-group OUTSIDE_VLAN20 out
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly in
 arp authorized
 arp timeout 3720

Then on the switch ports I was hoping it would be as simple as

interface FastEthernet0/1/0
 description UPS Failover Link
 switchport access vlan 10
 no ip address

I did try turning it in to a trunk port and putting encapsulation dot1Q 10 and then setup a vlan on the UPS but that did not work. I also added access VLANS on the router to no avail. Anyone know if this is even possible? I haven't found any supporting evidence so far.

 

Thanks very much.

Hi,

What type of router are you using?  Can you provide the part number or describe the type of HWIC card you are using?

 

Hi Reza,

 

I am using a 1921 with adv-ipservices and the WIC card is a  HWIC-4ESW (4 port switch card).

 

Thank you.
