Hi guys,
Need some advice.
One of the interfaces on my border routers is consistently getting
AMDP2_FE-3-UNDERFLO messages during its peak usage (9am-5pm) hours. The
interface FastEthernet2/0 is seeing approx 40Mbps out and 15 Mbps in.
The explaination for this error on Cisco website is:
------------
Explanation While transmitting a frame, the controller chip's local
buffer received insufficient data because data could not be transferred
to the chip fast enough to keep pace with its output rate. Normally,
such a problem is temporary, depending on transient peak loads within
the system.
Recommended Action The system should recover. No action is required.
------------
I need some convincing of that. Of late, i've received a few reports of
packet loss to my network of late, and am not sure if this transmit
error has anything to do with it. Any help is much appreciated! FYI, the
router in question is a Cisco 7206VXR. The interface is 100Mbps capable.
