| Description |
| Separating critical system components and functions from other noncritical system components and functions through separate subnetworks may be necessary to reduce susceptibility to a catastrophic or debilitating breach or compromise that results in system failure. For example, physically separating the command and control function from the in-flight entertainment function through separate subnetworks in a commercial aircraft provides an increased level of assurance in the trustworthiness of critical system functions.

| Configure the layer 2 switch to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. 1. Add appropriate VLAN by name. device# configure terminal Router(config)#vlan 5 Name Organization_A Router(config)#vlan 10 Name Organization_B Router(config)#vlan 10 Name IP_Phone 2. Add untagged Ports for the specific ports to the VLANs as needed. Router(config-vlan-5)#untag ethernet 1/1/2 3. Add tagged ports. Router(config-vlan-5)#tag ethernet 1/1/4 4. Save the configuration. Router(config-vlan-5)#write memory |
