What are interface throttles?
What are interface throttles?
Generically speaking, a throttle occurs when the interface is not able to process any more packets due to buffer or processor overload.
What is throttles in Cisco router?
If the input queue is constantly overloaded, the Cisco IOS Software throttles the interface. This prevents the input queue from accepting any new packets for a short period of time, allowing the router to empty the input queue.
What is reliability in Cisco?
Reliability is calculated like this: reliability = number of packets / number of total frames. The value of 255 is the highest value meaning that the interface is very reliable at the moment. The calculation above is done every 5 minutes.
How do you check interface utilization on a Cisco switch?
Use the show interface port-utilization command to view a real-time rate display for all ports on the switch.
What is runts in Cisco interface?
Runt packets are packets that are less than the minimum packet size (64 bytes for Ethernet). They often occur due to collisions on the line. On switches the cause is usually a mis-matched duplex problem (full on one end and half on the other) caused by bad autodetection of a device.
What is Cisco watchdog?
Cisco processors have timers that guard against certain types of system hangs. The watchdog timer basically controls the time of each process. If the timer is not reset, a trap occurs.
What causes input errors on an interface?
Input error: Includes runts, giants, no buffer, CRC, frame, overrun, and ignored counts. Other input-related errors can also cause the input errors count to be increased, and some datagrams may have more than one error; therefore, this sum may not balance with the sum of enumerated input error counts.
What is interface utilization?
Last Updated May 18, 2021. The Interface Utilization view lists the interfaces throughout the enterprise that are the most heavily used. The view is a table summary of the interfaces whose utilization exceeds the user-configured thresholds. This view is located on the Enterprise Overview page.
How do I monitor traffic on a Cisco router interface?
How to: Monitoring traffic with Cisco port monitoring.
- Step 1: Connect to your switch (telnet, ssh, whatever method you want)
- Step 2: Enter enable mode.
- Step 3: Enter the configuration terminal.
- Step 4: Enter your interface’s configuration.
- Step 5: Configure which ports to monitor.
- Step 6: Save your configuration.
What causes Cisco runts?
Runts are Ethernet packets that are less than 64 bytes and may be caused by excessive collisions.
What causes runt?
There are a number of possible causes of runts, none which should occur on a normal, healthy network! The most likely causes are excessive collisions, which may distort Ethernet frames, causing only the first half of a frame to be seen before it is cut off by a collision.
