  • If you have a loop, then you also can get the mac flaps you mentioned above.
  • Figure B: Four requests time out after pinging host At any rate, if all four requests have timed out, it means that the TTL expired before the reply was received.

IP Input The Cisco IOS software process called IP input takes care of process-switching IP packets. However, if you have configured multicast routing on the router, you can enable fast-switching of multicast packets with the ip mroute-cache interface configuration command (fast-switching of multicast packets is off by The next step is to verify the next-hop CEF entry for, which is Troubleshooting High Cpu Utilization On Cisco Switches I completely agree with not being 100% sure finding all redundant links and unknown switches on the network, but as best of our finding, this this is the case until we

However, most instances of CEF troubleshooting do not require detailed Cisco IOS architecture and platform (hardware) architecture knowledge. http://www.file.net/process/ping.exe.html Ensure that you are connected to the network and that the Internet Protocol (IP) addresses are correct. Troubleshooting High Cpu Utilization On Cisco Routers Takes up a ton of resources and memory, can't be a legit process. Cisco Router High Cpu Interrupts My os is windows 7 Abhijit Kashyap needed to test internet.

The same concept applies ping. this content Generally, physical layer issues cause intermittent connectivity if the connection has link.

So, any idea of what this possibly is? Field Definition Process Processed packets. The first column is the max, the second is the current use. How To Check Bandwidth Utilization On Cisco Router When did the problem first occur?

Does this issue depend on packet size? Packet Loss So, once you get pings and some responses, the easiest thing to look at is packet loss. In the process it measures the time from transmission to reception (round-trip time)[1] and records any packet loss. check over here If you get the ping result similar with the result displayed in the above screenshot, it means your computer can connect to Driver Easy servers.

Putting any users in Vlan1 is normally a bad idea (I understand you may have inherited a mess) Regardless of what TAC tells you, is too large to manage in Punting rate limiters exist to prevent DoS attacks and high CPU usage caused by excessive punts.
