Hi

 

In verification section of Gre Tunneling which is

 

<span class="code-bold">R1#monitor capture GRE match any interface gigabitEthernet1.13 both</span>
<span class="code-bold"><br /></span>
This command doesnt exist, Am I using worng IOS , though its same as recommended for GNS3 7200

R1#monitor capture ?

  • Hi,

    The command you have mentioned is available in IOS XE - CSR1000v environmment. For regular IOS, you could reference the command reference, see below :

    http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/epc/command/monitor_capture_through_show_monitor_capture.html

    or the embedded packet capture configuration guides : 

    http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/epc/configuration/15-mt/epc-15-mt-book/nm-packet-capture.html

     

    Hope it helps.

     

  • Hello Ciprian, 

    Following the EPC configuration guide IOS 15 M&T  I am able to setup a monitor capture and a monitor buffer.  I am not however able to get the same output as Brian does for the example in the workbook. 

    It looks like the packet capture is not able to detect any GRE packets going accross the interfaces.  Here is my configuration and relevant output.   

    Please let me know if you are able to replicate Brian's output on IOS using the method you described above. 

    Thank you. [:)]

    R1#monitor capture buffer GRE 

    R1#monitor capture point ip cef GRE_packets gigabitEthernet0/1.13 both 

    %BUFCAP-6-CREATE: Capture Point GRE_packets created.

    R1#monitor capture point associate GRE_packets GRE 

    R1#monitor capture point start GRE_packets

    %BUFCAP-6-ENABLE: Capture Point GRE_packets enabled.

     

    R1#ping 150.1.3.3 source lo0

    Type escape sequence to abort.
