Description
To deploy a management network for the purpose of controlling, monitoring, and restricting management traffic, a separate management subnet must be implemented. Define a large enough address block that will enable the management network to scale in proportion to the managed network.
ℹ️ Check
Review the network topology diagram to determine if a management network has been implemented. Validate the IP address space documented for this network by verifying the IP addresses referenced for management access (SSH, NTP, AAA, SNMP manager, Syslog server, etc.) to the managed network elements.
If a management network has not been implemented, this is a finding.
✔️ Fix
Define a large enough address block that will enable the management network to scale in proportion to the managed network.
