Hi Dejan,
Please see the Support Compatibility Matrix link below and search "2.3 Network Devices" for a list of officially supported network devices. FYI: This is where we document all officially supported OS information for other devices too.
PAM Support Compatibility Matrix
As a note, we know some network devices are able to use SSH authentication, if the device is not officially listed but does support SSH with unix-like operators it may be possible to get it working through the UNIX (SSH) Connector, but may not be supported officially.
If not supported and doesn't work through SSH then the only thing we can really offer is to use the Generic Target Application type to store passwords, but they would likely not be rotatable or usable with auto-connect.
