SUMMARY
LLDP Neighbor Descriptions may contain multi-line text. Subsequent lines will not be prepended with Neighbor System-Description : (or any other predictable text) and will produce a State Error.
STEPS TO REPRODUCE
- Execute the
aruba_aoscx_show_lldp_neighbors-info_detail.textfsmtemplate against a device that has a LLDP Neighbor which returns multiple lines for its description.
EXPECTED RESULTS
LLDP Neighbor information is parsed successfully.
ACTUAL RESULTS
Error received:
Parsing failed for 'show lldp neighbor-info detail' command:
