Hi all, i have a 2821 router ios version 12.4(5b) with a nm-esw-16 card. Whenever I install a second card (HWIC-D-9ESW), I cannot communicate with device pluged in the nm-esw-16 card.
Any idea ?
Multiple Ethernet Switch HWICs or network modules installed in a host router will not act independently of each other. They must be stacked, as they will not work at all otherwise.
