The RUCKUS ICX router must implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions.

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.

Verify the router is configured to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. If the router is not configured to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions, this is a finding.

Configure the router to implement physically or logically separate subnetworks to isolate organization-defined critical system components and functions. Configure VLANs separate organization-defined traffic: device# configure terminal device(config)# vlan 235 name mgmt-vlan device(config-vlan-235)# tag ethernet 1/x/x device(config-vlan-235)# interface ve 235 device(config-vif-235)# ip addr x.x.x.x/x device(config-vif-235)# vlan 200 name ops-vlan device(config-vlan-200)# tag ethernet 1/x/x device(config-vlan-200)# interface ve 200 device(config-vif-200)# ip addr x.x.x.x/x device(config-vif-200)# vlan 210 name user-vlan device(config-vlan-210)# tag ethernet 1/x/x device(config-vlan-210)# interface ve 210 device(config-vif-210)# ip addr x.x.x.x/x device(config-vif-210)#end device# write memory
