fmc-perl

Perl Module for interacting with the Cisco Firepower Management Center API.

Features

  • Connect to a Cisco FMC and obtain an authentication access token. Token gets explicitly revoked once connection is no longer needed (e.g. script terminates).
  • Get a Network Group, either by group name or group UUID and return group name, group UUID and it's associated values.
  • Update a Network Group's values and optionally merge new values with existing values instead of overwriting existing values.

Missing Features

  • Currently only supports Network Groups.
  • Does not yet support deploying changes to devices.

To Do

  • Comments/documentation.
  • Improved error handling (use croak?).
  • Better error checking.
  • Add missing features.
  • Broader testing (only tested against Cisco FMC v6.2.3.3).

Example

Included is an example that uses the FMC Perl module. It connects to the FMC and gets a Network Group called TestGroup. This returns all the current values of TestGroup. The script then resolves an FQDN using two different DNS servers and then updates, by merging the new and existing values, the TestGroup Network Group.

Here's what this looks like with the verbose option enabled:

Revoking access to the FMC at FMC.pm line 29.

In the real world this could be useful to keep Network Groups that represent FQDNs up to date, since Cisco FTD currently lacks FQDN support.

You can’t perform that action at this time.
