Error when polling device

[cohearne77]

Hi, hoping someone can help with the following issue:
Error when polling device --*** 'vlanshowplist-ifidx'

trying to poll an nxos device using driver nxos_ssh and importer looks ok on debug logging into the device , it runs a set of commands but fails while executing 'vlanshowplist-ifidx'

I am something of a novice with devnet and have sorted out a few other issues but I am completely stuck with this one.

Thanks
