hardware address

[Nuno Castro]

Hello all;

I have an Access Point enginius 2610, connected directly to cisco 877 router Port F2. Seems that the router isn't recognizing the mac of the Access Point, and is always putting the port in down state.

Access point:

IP: 10.0.0.2 Mac:0002.6f57.8e14

Here is some commands:

sh arp

 - Besides 'term mon' could you also have a look at the complete logs of the router as in

# show  loggging

The original post had this line

FastEthernet2              unassigned      YES unset  down                down

If FastEth2 is down then that explains why the router is not recognizing the mac of the access point.

The more recent post has this line

FastEthernet2              unassigned      YES unset  up                    up

If FastEth2 is now up then perhaps the router now recognizes the connection of the access point? Other than show arp how are you checking for the connection of the access point?

Would you post the configuration of interface FastEth2?

Helo;

Thanks a lot Richard. I have solved the problem, adding

 duplex full
 speed 10

In port configuration.

Thank you for posting back to the forum to let us know that you solved the problem by changing port parameters for speed and duplex. I am glad that you were able to get the problem worked out.
