Cisco Device Management
IOS, NX-OS, and ASA — managed, backed up, monitored
What it does
AlertMonitor provides full lifecycle management for Cisco infrastructure: IOS switches, NX-OS Nexus fabric, and ASA/Firepower firewalls. Device configurations are backed up daily, VLANs and ACLs are visible from the dashboard, VPN session counts are tracked, and interface stats are monitored continuously. When a config change is detected outside a change window, an alert fires immediately.
Configuration drift is a security event: An unexpected ACL change on a firewall, a new VLAN spanning segments that shouldn't communicate, a VPN configured to allow split tunneling — these are security events that don't generate a Windows log. AlertMonitor catches them at the network layer.
Capabilities
- Daily automated configuration backups for all Cisco IOS, NX-OS, and ASA devices
- Config diff alerting: any change outside approved maintenance windows triggers analyst review
- VLAN inventory and change tracking — new VLANs, trunk changes, access port reassignments
- ACL visibility and change monitoring across all managed firewalls
- VPN session metrics: active tunnels, user counts, failed authentications
- Interface statistics: utilization, errors, flap history per port
- Restore capability: push previous known-good config to device via AlertMonitor console
How it works
AlertMonitor connects to Cisco devices via SSH using read-only monitoring credentials. Configuration collection uses TFTP or SCP for backup depending on device capability. Config diffs are stored with full revision history. Real-time monitoring uses SNMP v3 for metrics collection alongside SSH-based config polling. The platform supports Cisco IOS 15.x+, NX-OS 7.x+, and ASA 9.x+.
