Hiya doin' folks,
I'm currently having some trouble with EPC running on IOS XE WS-C3650-48PD 16.6.5.
I can configure it just fine and the output of "show monitor capture mycap" and / or "show monitor capture mycap parameter" lokks good, just as it should be, but....
the buffer is empty. There are no packets captured in the buffer. I can export the file to flash or ftp server and open it in wireshark but it's empty. The "show monitor capture mycap" also show 0 packets captured.
Here's what I do:
Switch# monitor capture mycap interface GigabitEthernet1/0/3 both
Switch# monitor capture mycap match ipv4 any any
Switch# monitor capture mycap buffer circular size 30
Switch# monitor capture mycap start
Switch# monitor capture mycap stop
Switch# show monitor capture mycap brief
Switch# show monitor capture mycap dump
I did the same procedure on an IPBASE switch and it work, besides that I didn't store it in buffer but directly had it copied into flash. Of course, the EPC only supports buffer option with possibility to export it.
Anyone? I'd be really thankful.
Solved! Go to Solution.

Thank you for your reply. I'm aware of the document, but the issue is that the buffer is empty. So I'm unable to check traffic directly on the switch.
But the export command is there, in order to export buffer content into pcap file and it works as well:
monitor capture TESTPCAP export ftp://myserver
Nevertheless,
I'm unable to populate buffer with traffic, so I'm unsure why isn't there any traffic coming into buffer?

Thank you Mark for your swift replies.
Than I'll just leave it as it is, as I already invested too much time in troubleshooting.
Will try on the next reelases again when we update the switches.
Gonna mark your answer as solution in case anyone else has troubles strugling with this one.
Cheers

Hi Zoran
Were you able to resolve embedded capture issue on devices running 16.6.5?
I have noticed that capture buffers is always empty on each of tested numerous switches running 16.6.5. However, capture is working properly other switches running 16.3.7 or 16.9.4.
I don't share Mark's view on the license level impact. I believe, Lanbase level seems to be fine for embedded capture.
Best regards

Hi Modestas,
sorry for the late reply. No, I wasn't able to solve this so I just let it as it is. no packet capture on devices running lan base.
Cheers
