Packet drops in serial interface

[ajothomas]

Hi All,

We have a Cisco 1760 router .

We are facing sevier packet drops in the serial interface.

When i swap the router with another router link is working working fine.

Troubleshooting steps taken

        1.       Swap the serial cable with another working cable : no change in state

        2.       Reconfigure the encapsulation commands (with PPP and HDLC) : no change in state

         3.       Try with a decreased MTU packet Ping : no change in state

        4.       Decreased the Input queue and increased the output queue size using

                  hold-queue in command : Comparatively the packet drop is reducing but still a 10 percent drop is happening.

Any body please suggest me how to proceed here.

Is it a hardware problem?

Thanks in adavance!

Regards,

Ajo Thomas

Dops are normal when interface is congested. Before messing around, you could have searched forum or the intenret, for the millions of discussions on the subject.
