Problems with etherswitch HWIC on 1841

I have a Cisco 1841 router with an ADSL card (WIC-1ADSL-DG) and I recently added an etherswitch card (HWIC-4ESW). The problem that I'm having is that any device connected to the etherswitch card can't see my network. I want to find a way to connect the etherswitch card to my router's network without setting up a truncking port and then connecting a crossover cable from the etherswitch card to the second built-in ethernet interface on the router.


Re: Problems with etherswitch HWIC on 1841

u should creat a vlan and vlan interface for ur etherswitch

as follow

vlan database

vlan 10 name data_vlan

then make and SVI interface

interface vlan 10

ip address

no shut

this should be ur internal network


interface range FastEthernet0/1-16

switchport mode access

switchport access vlan 10

no shut

spanning-tree portfast

Ethernet switch module can function as a Layer 2 switch connected to a Layer 3 router

then should work

and the following link will guid you in more details

good luck

please if helpful Rate

Re: Problems with etherswitch HWIC on 1841

It dosn't seem to be working. For one thing, when I assign my vlan an ip address that's in the same range as my router, I get the error: " overlaps with FastEthernet0/0" If I assign vlan 1 an ip address in a different range, any computer attached to it can't go out to the internet because the default gateway is on a different network.

Re: Problems with etherswitch HWIC on 1841

when u assign vlan 1 ip address for example

interface vlan 1

ip address

no shut

ur users must be on the subnet

and thier default gateway must be vlan 1

which is

i mean the users connected to the etherswitch and are on vlan one

good luck
