How do you clear the counter on a Cisco router?

To clear the interface counters, use the clear countersinterface command in EXEC mode mode.

1. clear counters interface [{all | type interface-path-id}] Syntax Description.
2. Specifies interfaces. interface.
3. (Optional) Clears counters on all interfaces. all.

What is interface output discards?

“output discard” is a packet that passed through the fabrinc interface, but was dropped because the host-interface (HIF) buffers are full.

How do I clear unknown protocol drops?

If the receiving end gets the CDP packet and has “no cdp enable” in the interface configuration – those announcements count as “unknown protocol drops”. The solution is to make the CDP settings, enabled or disabled, consistent on every device in the interface’s scope.

How do I increase the number of input queue drops?

The system counts input queue drops if the number of packet buffers allocated to the interface is exhausted or reaches its maximum threshold. You can increase the maximum queue value with the hold-queue command for each interface (the queue length value can be between 0 and 4096. The default value is 75).

How to fix output drops on interface?

Output drops are generally caused by congested interfaces and best possible option to address this situation is to look into increasing the speed of that link. Other factors may also be responsible for causing output drops on interfaces. Some of common causes of output drops on interface are enlisted below –. Bad cable.

Why is my input queue drop counter not working?

If input drops are still present, it implies that there is simply too much traffic. Consider a hardware upgrade, or try to decrease the traffic load. These are the conditions for input queue drop counter.

What is the difference between output drop and output queue drop?

Output queue drops occur only if the interface is already congested at interrupt level, so that packets cannot be pulled out of the output queue before the queue becomes full. Therefore, output drops at processing level (output queue drops) and output drops at interrupt level always occur together,…
