Cisco 2611 Led Activity anormaly blinking on DDR request

[admin_2]

Hello,

I have a cisco 2611 router and I want to connect this router with another 2611 router.

To perform this, i using isdn line configuring with dialer(DDR connection).

The problem is that the activity's led start to blink anormaly (very fast) when a packet is send to the BRI interface (Request for isdn connection).However when I show the processes, the router seem run correctly.

The only procedure that i have find to reselve this is to reload the router.

I realized that when the router have already receive a call from the calling router, the activiti's led run normaly.

Thank you for your help

This can be because of a bug CSCdm68129 which is there in 12.0 version IOS of 2600 and this is fixed in 12.1(3.1).

This can be even if you don't have any traffic , more information you can search in the bug tool kit.
