The -p option in the ping command allows users to specify a The Cisco IOS software allows the subsystem components to define whether support for event tracing is enabled or disabled by default. When the server's packets that it tries to send at a higher rate start dropping, it will notice that TCP acknowledgements for some segments don't arrive. Ping output can help you evaluate path-to-host reliability, delays over the path, and whether the host can be reached This is the type of output you will see with random packet loss.

Must use same-VRF IP address or full interface name without spaces This chapter contains the following sections: ping ssh telnet traceroute ping Use the ping EXEC mode command to send ICMP echo request packets to another node on the network. The traffic flows from the client to the web server will enter (ingress) the router via gi0/1 interface and exit (egress) the router via gi0/2 interface. A "show interface XX" command will show you the MTU/size for egress and ingress packets on an interface. 5. 168. F.
