Extended ping With Cisco


This post just reminder for me, the technical part of extended ping for Cisco device

reference from cisco official web http://www.cisco.com/c/en/us/support/docs/ip/routing-information-protocol-rip/13730-ext-ping-trace.html

I only take the technical parts for my own purpose :)

FieldDescription
Protocol [ip]:Prompts for a supported protocol. Enter appletalk, clns, ip, novell, apollo, vines, decnet, or xns. The default is ip.
Target IP address:Prompts for the IP address or host name of the destination node you plan to ping. If you have specified a supported protocol other than IP, enter an appropriate address for that protocol here. The default is none.
Repeat count [5]:Number of ping packets that are sent to the destination address. The default is 5.
Datagram size [100]:Size of the ping packet (in bytes). Default: 100 bytes.
Timeout in seconds [2]:Timeout interval. Default: 2 (seconds). The ping is declared successful only if the ECHO REPLY packet is received before this time interval.
Extended commands [n]:Specifies whether or not a series of additional commands appears. The default is no.
Source address or interface:The interface or IP address of the router to use as a source address for the probes. The router normally picks the IP address of the outbound interface to use. The interface can also be mentioned, but with the correct syntax as shown here:
Source address or interface: ethernet 0 
Note: This is a partial output of the extended pingcommand. The interface cannot be written as e0.
Type of service [0]:Specifies the Type of Service (ToS). The requested ToS is placed in each probe, but there is no guarantee that all routers process the ToS. It is the Internet service's quality selection. The default is 0.
Set DF bit in IP header? [no]:Specifies whether or not the Don't Fragment (DF) bit is to be set on the ping packet. If yes is specified, the Don't Fragment option does not allow this packet to be fragmented when it has to go through a segment with a smaller maximum transmission unit (MTU), and you will receive an error message from the device that wanted to fragment the packet. This is useful for determining the smallest MTU in the path to a destination. The default is no.
Validate reply data? [no]:Specifies whether or not to validate the reply data. The default is no.
Data pattern [0xABCD]Specifies the data pattern. Different data patterns are used to troubleshoot framing errors and clocking problems on serial lines. The default is [0xABCD].
Loose, Strict, Record, Timestamp, Verbose[none]:IP header options. This prompt offers more than one option to be selected. They are:
  • Verbose is automatically selected along with any other option.
  • Record is a very useful option because it displays the address(es) of the hops (up to nine) the packet goes through.
  • Loose allows you to influence the path by specifying the address(es) of the hop(s) you want the packet to go through.
  • Strict is used to specify the hop(s) that you want the packet to go through, but no other hop(s) are allowed to be visited.
  • Timestamp is used to measure roundtrip time to particular hosts.
The difference between using the Record option of this command and using the traceroute command is that, theRecord option of this command not only informs you of the hops that the echo request (ping) went through to get to the destination, but it also informs you of the hops it visited on the return path. With the traceroute command, you do not get information about the path that the echo reply takes. The traceroute command issues prompts for the required fields. Note that the traceroute command places the requested options in each probe. However, there is no guarantee that all routers (or end nodes) process the options. The default is none.
Sweep range of sizes [n]:Allows you to vary the sizes of the echo packets that are sent. This is used to determine the minimum sizes of the MTUs configured on the nodes along the path to the destination address. Performance problems caused by packet fragmentation is thus reduced. The default is no.
!!!!!Each exclaimation point (!) denotes receipt of a reply. A period (.) denotes that the network server timed out while waiting for a reply. Refer to ping characters for a description of the remaining characters.
Success rate is 100 percentPercentage of packets successfully echoed back to the router. Anything less than 80 percent is usually considered problematic.
round-trip min/avg/max = 1/2/4 msRound-trip travel time intervals for the protocol echo packets, including minimum/average/maximum (in milliseconds).
