Cisco Router 857 supports switchport command?

[hiro.sama]

Cisco 857 router has 4 ports

and I would like to configure multiple subnets in different interfaces in cisco 857

It seems to be 2 options to achieve this L2 ports to make it work as L3 port below.

If the port can be L2 or L3 then

config t
no switchport
ip addresss

If it is only L2 port then

int vlanZ
ip address ....
int X
switchport access vlan Z

However, in my try, neither "no switchport" nor "switchport access vlan Z" is working.

my show version result iis below. would you please tell me how to configure L2 port into L3 port for my router

Hi,

However, in my try, neither "no switchport" nor "switchport access vlan Z" is working.

AFAIK you can't configure VLANs on a 857 and the switch ports are L2 only.

I can assign ip address to vlan,

int vlanZ
ip address ....
int X

but What i can not do is switchport command to assign this vlan to the port.

Is there anyway to construct different subnetwork in different port with this router?

because it is the whole point why I bought this router.

Hi,

  Please try add another vlan in vlan database.

R857#vlan database

R857(vlan)#vlan 2

  If it's not allowed you to create more than 1 vlan in DB. This router won't support "switchport access vlan". Cisco877 can add more than 1 vlan I used to do it.  I think that "no switchport" command doesn't support on this platform.

HTH,

Toshi

Hi,

  It doesn't support to do what you want. You need cisco 870 series to do so.

  Ref: http://www.cisco.com/en/US/docs/routers/access/800/850/software/configuration/guide/dhcpvlan.html

  However, If you just want to differentiate users and don't care about the broadcast domain and security policy won't be applied on gateway, you can use "secondary ip address" on interface-vlan 1".

HTH,

Toshi

Je vous remercie de votre conseil toshi. je vais essayer ca et je vous dirai le resultat.

850 will support only ONE (1) VLAN.

The 870 (depending on what IOS version your running) will support either TWO (2) or TEN (10) VLANs.
