SUMMARY

If there is no Type value the script aborts.

STEPS TO REPRODUCE

Use ssh_con.send_command('show interface status', use_textfsm=True) with a Cisco N2K-C2248TP-E-1GE connected.

EXPECTED RESULTS

That an empty string is returned for interfaces without type.

ACTUAL RESULTS

The scripts aborts.

textfsm.parser.TextFSMError: State Error raised. Rule Line: 14. Input Line: Eth105/1/1    --           notconnec 201       full    1000

This fixes it if you want to set Et105/1/1 as having a type of "".

Thoughts?
