2801 with a 9 port Ethernet HWIC

have a 2801 with a 9 port Ethernet HWIC and a 4 port Ethernet HWIC. If you plug a machine into the switch modules, the machine will not pick up a dhcp address. If you put a static address on the machine, you can not ping the default gateway. You can ping another machine that is plugged into either the 9 port or 4 port modules. If you plug a cable into fa0/0 and the other end into the switch module, it still does not work. It is like the switch modules want to stay in their own little world.

any one any ideas how i manage to get devices plugged into the module switch ports to see the outside past the module

cheers for any info

hi

Can you give some lead on how the configuration is done ? have you configured any SVI and have ip assigned to that interface ?if thats the case have you made all these ports as a member of that vlan ?

if possible do post your configs here with both your public ips and passwords masked ..

As this is a switching module you must also configure the vlan database, either through the (deprecated "vlan dat" command or via the IOS config)

Your switched vlan ports might be down otherwise.

The problem may also lie in the switchport mode trunk command that you have put on all ports. With the latest software you should configure the ports in access mode with an additional switchport voice vlan command.

The netto result of that is that it works as desired. I have not found any docs on the deeper issues behind this (may be something with autonegotiation) but in practice, it worked with me.

Leo

Hello,

multiple Ethernet Switch HWICs installed in a host router will not act independently of each other. You need to configure stacking for both modules, as they will not work at all otherwise.

Stacking is the connection of two switch modules resident in the same chassis so that they behave as a single switch. When a chassis is populated with two switch modules, the user must configure both of them to operate in stacked mode. This is done by selecting one port from each switch module and configuring it to be a stacking partner. The user must then connect with a cable the stacking partners from each switch module to physically stack the switch modules. Any one port in a switch module can be designated as the stacking partner for that switch module.

Beginning in privileged EXEC mode, follow these steps to configure a pair of ports on two different switch modules as stacking partners.

COMMAND SUMMARY STEPS

1. interface fastethernet interface-id

2. no shutdown

3. switchport stacking-partner interface FastEthernet partner-interface-id

4. exit

5. interface fastethernet partner-interface-id

6. no shutdown

7. end

Regards,

Nethelper
