An example may be to treat a# host that appears in the CDP table differently from one that does not, and# collect a other command outputs in that case## Tested and validated on Nexus 9000 6.1(2)I2(2a)## A best effort was also made to try to run it on other platforms, but was only# tested on Nexus 5000 5.2(1)N1(6)## For Nexus 5000 support, this depends on xmltodict# https://github.com/martinblech/xmltodict/blob/master/xmltodict.py##import reimport pprintimport jsonfrom argparse import ArgumentParser
## This entire block of code is aimed at detecting of we have access to cli and# the clid command. If we do not have them, we attempt to import cli from the# cisco package (which is present on other NXOS platforms). If that fails, we# cannot proceed further. However, if it does succeed, then we need to create# an equivalent of clid(), so we introduce an external dependency on xmltodict# which is used to convert the XML output of the commands into a JSON dict.## Finally, after that we check to see if cli() returns a tuple, if so that means# we are on a 5K or similar, and we need to patch the output to return it as# just the command output, and not the two-tuple
