DELL 9.8(0.0) User Manual

• Host mode — When a policy with device role as host is applied on an interface, all the RA packets are 

dropped without validation. You can also configure the host mode policy with VLAN option to drop 

the RA packets on that specific VLAN and port.

• Router mode — When a policy with device role as router is applied on an interface, all the RA packets 

are validated based on the configuration information in the policy. Similarly, you can also apply this 

mode over any specific VLAN and the validation is performed only for that particular VLAN RA packets.
