So we're finally replacing an old Cisco 2801 router with a fancy new ISR 4431. However we've been caught out, the old 2801 had access vlans assigned to physical interfaces and it seems this is a no-no on a 4431.
Is our only solution to put in a switch module?
Below is what we used to have.
interface FastEthernet0/3/0
description FW
switchport access vlan 202
duplex full
speed 100
!
interface FastEthernet0/3/1
description FW
switchport access vlan 202
duplex full
speed 100
!
interface Vlan202
ip address 192.168.0.5 255.255.255.0
