HWIC-4ESW card in 1841 router

[sqambera]

Hi,

Can anyone please help me to know what we can do with HWIC-4ESW card in 1841 router? I am asking this because neither a vlan interface can be created on 1841 nor a port of said card can be converted to routing port. So how will 1841 will do routing between anything connected on HWIC-4ESW port and any other port of router? Thanks.

Hi,

You can certaily create vlan interfaces for it and have the inter-vlan routing done through the router.

n order to assign the IP address to the HWIC-4ESW, please select the interface vlan 1, in

this interface you can assign the wanted IP. After type the no shut command for this

interface, the 4 ports take the IP address to proceed with the VLAN configuration.

router(config)#int vlan 1

router(config-if)#ip address #.#.#.# #.#.#.#

router(config-if)#no shut

If you want to route in the 4 ports, you need to create 4 vlan id's and assign every vlan

to the interface.

You can check this in the next example :

Router# vlan database

Router(vlan)# vlan 2

Router(vlan)# vlan 3

Router(vlan)# exit

Router# conf t

Router(config)# interface Fe0/2

Router(config-if)# switchport mode access

Router(config-if)# switchport access VLAN 2

Router(config-if)# exit

Router(config)# interface Fe0/3

Router(config-if)# switchport mode access

Router(config-if)# switchport access VLAN 3

Router(config-if)# exit

Router(config)# interface VLAN 2

Router(config-if)# ip address

Router(config-if)# no shut

Router(config-if)# exit

Router(config)# interface VLAN 3

Router(config-if)# ip address

Router(config-if)# no shut

Router(config-if)# exit

I am attaching some more info for this module:

Hi,

Thanks for replying. I am testing a 1841 router for the configurating example you posted. Still I haven't inserted HWIC-4ESW card in it. I can create vlans in vlan-database but after exiting from the vlan-database when I try to go to int vlan like:

(Config)#int vlan2

it does not allow me to go to interface. Is it because first I have to insert HWIC-4ESW card in router or any other reason? Thanks again.

Put HWIC there and then test this feature. It will only work with HWIC.
