Router1 is sending packets to Router4, but is not getting any answer from Router4. this contact form

We are sending our packets, but we are not receiving anything. It is effectively a bound on the number of routers an IP packet may pass through before being discarded. If the local computer's TCP/IP configuration is correct, you can still receive this message from your gateway.

Ping Messages Explained

A better way to test router performance is with traffic going through the router: The traffic is then fast-switched, and is handled by the router with the highest priority. Is there a rule for how to handle creative use of spells? How to Fix ICMP Error Code 31 Some times you may receive hardware error messages on your command prompt instead of normal ICMP error codes. This would indicate that your gateway does not have information in the routing table to successful route the packet to the destination host.

interface Serial1 ip address ! ! One way is to use access lists to narrow down the specific traffic that you want to monitor. You can refer to this IANA link for more information regarding types and codes for ICMP.

Ping Error Message General Failure

Here, the 0000.0000.0000 means that Router4 is looking for the MAC address of the destination navigate here Refer to Cisco Technical Tips Conventions for information on conventions used in this document. Ping Messages Explained Syntax C++ Copy typedef struct icmp_echo_reply32 { IPAddr                         Address; ULONG                          Status; ULONG                          RoundTripTime; USHORT                         DataSize; USHORT                         Reserved; VOID * POINTER_32              Data; struct ip_option_information32  Options; } ICMP_ECHO_REPLY32, *PICMP_ECHO_REPLY32; Members Address Type: IPAddr Ping Return Codes Windows TTL Expired in Transit The TTL value determines the maximum amount of time an IP packet may live in the network without reaching its destination.

Some packets are always processed, but with the appropriate configuration and in stable networks, the rate of processed packets must never congest the input queue. http://exactcomputerrepair.com/ping-error/ping-errors.html The ping is successful only if: the echo request gets to the destination, and the destination is able to get an echo reply back to the source within a predetermined time See Configuring Address Resolution Methods for a detailed explanation. We recommend that you carefully read the Use the Debug Command section before you issue debug commands. Ping Failure Reasons

Router1(config)#ip route Serial0 We now have: Router1#debug ip packet detail IP packet debugging is on (detailed) Router1#ping Type escape sequence to abort. Success rate is 100 percent (5/5), round-trip min/avg/max = 4/4/4 ms From the above, we see that the problem lies between Router2 and Router3. Basically, ARP is a protocol used to map the Layer 2 address (MAC address) to a Layer 3 address (IP address). navigate here However, the packet including IP and ICMP headers must be less than the maximum transmission unit of the network or risk being fragmented.

Success rate is 0 percent (0/5) This time, the source address is, and it is not working! Ttl In Ping Success rate is 100 percent (5/5), round-trip min/avg/max = 32/32/36 ms There is almost no difference. How does a 40 Gbit/s Ethernet interface process packets in silicon?

ICMP_ECHO_REPLY32 structure The ICMP_ECHO_REPLY32 structure describes the data returned in response to an IPv4 echo request on a 64-bit platform. Otherwise it exits with code 0. IP_DEST_NET_UNREACHABLE 11002 The destination network was unreachable. http://exactcomputerrepair.com/ping-error/ping-error-65.html Let us add a static route to Router4: Router4(config)#ip route Serial0 Now it works perfectly, and both sides can access each other: Router1#ping Type escape sequence to abort.

So not really useful for testing if a host is alive and IMO a bug. IP_HW_ERROR 11008 A hardware error occurred.

To fix this issue, we simply have to add a route to in Router2.

Success rate is 100 percent (5/5), round-trip min/avg/max = 36/36/37 ms Router4#undebug all All possible debugging has been turned off Router4#show log Syslog logging: enabled (0 messages dropped, 0 flushes, 0 You can change this default using an extended ping: Router1#ping Protocol [ip]: Target IP address: Repeat count [5]: Datagram size [100]: Timeout in seconds [2]: 30 Extended commands [n]: Sweep IP_NO_RESOURCES 11006 Insufficient IP resources were available. To test this out, try this snippet #!/bin/bash light_red='\e[1;91m%s\e[0m\n' light_green='\e[1;92m%s\e[0m\n' ping -c 4 -q google.comz if [ "$?" -eq 0 ]; then printf "$light_green" "[ CONNECTION AVAILABLE ]" else printf "$light_red"

Though the interface is up and you may not ping the device due to high input queue drops. End with CNTL/Z. For example type ping to see if the host with the IP address is reachable.
