Version 3.4

Note

v3.3 and up require Postgres version 13 or greater! (I.e. Ubuntu 20.04 will no longer work.)

Version 3.4 adds support for IPv6, Cisco CBS and MikroTik devices, Arista via eAPI, and can produce a graphic view of all device neighbors.

New Configuration Options

IPv6 related:

# if set to True, IPv6 addresses will be shown with UPPER case letters.
# default is lower case.
IPV6_USE_UPPER = False

# if set to True, the IPv6 Link-Local address of interfaces will be shown (if known)
# note this is link-specific, and not very useful!
IPV6_SHOW_LINKLOCAL = False

Neighbor Graph Options:

# Mermaid graphs of connected devices  (neighbors) can be simple or expanded.
# Simple shows current device interface and connected neigbor.
# Expanded also show the remote neighbor interface, if shown.
# default is simple, ie. False. Set to True for slightly more interesting graph.
MM_GRAPH_EXPANDED = False
