I have set up a local SPAN but only see packets going in one direction, so I have been researching to find out how to do a bi-directional SPAN. I have tried the step shown at 1:55 but when I enter any of the IP addresses I see in my capture into either of the Source or Destination Target windows and hit Search It says "No items have been found". This makes no sense.
HI Sonu, we try to capture packet as you demo but APIC reply with "Inband Mgmt must be configured on the relevant leave and the APIC"
Could you suggest what is the prerequisite we have to do?
Hi Max, sorry for late reply. I did not get any notification. Yes inband configuration is must for capturing packets on APIC
I need to know how to capture packets both entering and leaving a Leaf port and send them to either a Leaf or Spine port that I would have an analyzer connected to. So far I have been unable to find this. Any assistance would be appreciated.
Hi Ronald, thanks for reaching out with your questions. We'd love to help, please take a look at our troubleshooting guide for more information here: cs.co/6059KXZAW. Thank you!
Actually its not bit clear about the Source IP Prefix (172.x.x.x) used in the SPAN window. Is it a random subnet which can be used ?
same issue
@@ccieliu Yes, it can be a random subnet
Yes, it can be a random subnet. This subnet is used to identify the leaf where packet is found. if the last octet of this subnet in the PCAP file is 101, it means packet was found of Leaf101.
@@sonukwl does it mean vtep IP of leaf ?
@@pendseshreyas no, it's the node ID of the leaf
