2901 doesn't recognize the Ethernet cards!

Hello,

i have a 2901 router (IOS version 15.3)  and after i plugged the Ethernet module into one of its EHWIC i found that the router doesn't detect it and the other router detected it and no traffice is passed through it. does any one know why that happened. BTW this Router should support 2 4-port Cisco Gigabit Ethernet EHWICs.

thank you!

Post the entire bootup process.

Hi Leo,

please find the boot process output that pasted below.

BTW when i connect two hosts on the same HWIC they reach each other but the problem is when i connect them on different HWIC cards.  thanks

Hi everyone,

i got the solution for this problem. and discovered that:

Only 2 HWIC or EtherSwitch network modules can be used in this platform and to let them communicate with eachother we have to stack them physically by an ethernet cable to use one port on each card as a trunk. and also we have to issue the command switchport stacking-partner on these trunk port to let the two HWIC cards have L2 connectivity.

please rate if you find it helpful. thanks!
