Automated Configuration Backup of Cisco Devices

So we all know backups of servers are pretty important, but what about the network fabric everything runs on? For most readers of this blog we’ve moved away from ‘dumb’ switches that you can connect to the LAN with no concerns about the underlying setup toward more intelligent switches that now perform port security, VLAN isolation … Continue reading Automated Configuration Backup of Cisco Devices

While this can be quite useful, it can also be quite restrictive - what … Continue reading Dynamic VLAN Assignment (Cisco and NPS)

The situation they had was that Cisco switches, routers and firewalls would use RADIUS to authenticate VTY sessions but over time the configurations … Continue reading Automate Your job – Synchronise NPS Servers and Push Config Changes to Multiple Devices
