The system installs a next hop that is on the directly connected subnet of current IP address on the 
interface (for example, if interface gig 0/0 is on 172.31.5.0 subnet, the system installs the static 
route).
The system also installs a next hop that is not on the directly connected subnet but which recursively 
resolves to a next hop on the interface's configured subnet. For example, if gig 0/0 has ip address on 
subnet 2.2.2.0 and if 172.31.5.43 recursively resolves to 2.2.2.0, the system installs the static route.
• When the interface goes down, the system withdraws the route.
• When the interface comes up, the system re-installs the route.
• When the recursive resolution is “broken,” the system withdraws the route.
• When the recursive resolution is satisfied, the system re-installs the route.
Configure Static Routes for the Management Interface
When an IP address that a protocol uses and a static management route exists for the same prefix, the 
protocol route takes precedence over the static management route.
To configure a static route for the management port, use the following command.
• Assign a static route to point to the management interface or forwarding router.
CONFIGURATION mode
management route ip-address mask {forwarding-router-address | 
ManagementEthernet slot/port}
Example of the show ip management-route Command
To view the configured static routes for the management port, use the show ip management-route 
command in EXEC privilege mode.
Dell#show ip management-route

Enabling Directed Broadcast
By default, the system drops directed broadcast packets destined for an interface. This default setting 
provides some protection against denial of service (DoS) attacks.
To enable the switch to receive directed broadcasts, use the following command.
• Enable directed broadcast.
INTERFACE mode
ip directed-broadcast
