hello togehter,

I have problem to capture data from the built-in ethanalyzer (wireshark) on a USB flash or Bootflash when the capture size reach 10MB. I tested with NX 4.2.4 and 5.0(2a). Is anyone know this issue?

how can I extended the capture size on the flashs?

best regards

Hello togehter,

I find the white-paper document for built-in wireshark on the Nexus 7010 self. the write option is limited to 10 MB.

you can start the analyzer with NX-OS# ethanalyzer local interface inband limit-capture-frame write

It is possible disabled the limitation?

best regards

hello ganesh,

do you know how I can disable the limitation when I use a usb flash, maybe a hidden command?

or plant cisco to extended the file size. In this case I will only sniffer the arp traffic which is running in the control plane policy for a longer time.

best regards
