General Management Considerations

General Management Considerations

The following are general NAC Controller management configuration considerations:

The Layer 3 NAC Controller is positioned inbetween two routers on the network. Only one VLAN/subnet spans between these routers as shown in Figure 6‐2. For Layer 3 NAC Controller configuration, all data traffic (non‐management traffic) traversing the NAC Controller between the upstream router and the downstream router must be untagged. The reason for this is that the NAC Controller does not preserve VLAN tagging for data traffic traversing the appliance, regardless of whether in‐band or out‐of‐band management is configured. The upstream and downstream routers must be configured with routed interfaces for this VLAN/subnet as shown below with IP addresses 20.20.20.2/24 and 20 20 20.1/24.

Figure 6-2 Layer 3 NAC Controller Positioning

When using In‐Band management:

Two IP addresses are assigned to the NAC Controller when configured for in‐band management; a management IP address for the NAC Controller Engine and a management IP address for the NAC Controller PEP.

The NAC Controller Engine IP address and NAC Controller PEP IP addresses, masks, and gateway must be part of the same subnet that spans the upstream and downstream routers.

No management VLAN ID is required. All management traffic sourced from the NAC Controller Engine and NAC Controller PEP egresses the upstream and downstream ports of the NAC Controller untagged onto the VLAN that spans the two routers, show as shown below.

A remediation web server IP address is not required. The remediation web server is run off of the management IP address of the NAC Controller Engine.

All directly connected management and router IP addresses on this subnet must be specified during the setup process in order to establish IP connectivity into the topology.

See Figure 6‐5 on page 6‐5 for a diagram on layer 3 In‐Band management. See Figure 6‐3 on page 6‐4 for a diagram on layer 2 In‐Band management.

When using Out‐Of‐Band management:

Three IP addresses are assigned to the Layer 3 NAC Controller when configured for out‐of‐band management; a management IP address and remediation IP address for the NAC Controller Engine and a management IP address for the NAC Controller PEP.
