We purchased some HWIC-4ESW modules for our 2811. I installed two on the Cisco 2811 router.
On the router I configure interface VLAN 1 with IP-address I used on laptop like default gateway.
From my laptop I can ping gateway only if I connected to first HWIC (in HWIC0 slot). If I uninstall first HWIC and connect my laptop to second HWIC (in HWIC1 slot) I can ping gateway again. So only one HWIC-module can work at once.
What I do incorrect? Can this modules work together?
In this coniguration guide it states that You have to configure "stacking-partner" to get the crossover cable to work.
