Hi all;
Can anyone please tell me whether they know if the Cisco 850's support configuring different LAN IP subnets, per FastEthernet switch port? I worked with a Cisco 837 which couldn't (although enabling the DMZ functionality did give extra segment).
PS. If it can't, how about the Cisco 870's?-
Thank you

Hi Michael,
Here is a link to the config guide for 850/870 routers.
http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/dhcpvlan.html
Basically, what you need to do is to
1. create the vlan database
router1(config)#vlan database
2. create layer 2 vlans
router1(config)#vlan 2 name network_mgmt
router1(config)#vlan 3 name data
router1(config)#vlan 4 name voice
3. Assign L2 vlans to a port on the switch.
router1(config)#
int Fast2
switchport access vlan 2
int Fast3
switchport access vlan 3
int Fast4
switchport access vlan 4
4. create layer 3 vlan interfaces for routing.
int vlan 2
ip address 192.168.2.254 255.255.255.0
no shut
int vlan 3
ip address 192.168.3.254 255.255.255.0
no shut
int vlan 4
ip address 192.168.4.254 255.255.255.0
no shut
Hope this helps :)

Your reply helps absolutely, thank you very much!
I take it from the FAQ
http://www.cisco.com/en/US/prod/collateral/routers/ps380/ps6200/prod_qas0900aecd8028a982.html
that since the 805 Series can handle only 1 VLAN; one'd need need a Cisco 870 Series (with the plus feature) set to implement VLANS above.
Thank you for time! :)
Very appreciated.
