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 congured 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 satised, the system re-installs the route.
Congure Static Routes for the Management
Interface
When an IP address that a protocol uses and a static management route exists for the same prex, the protocol route takes precedence
over the static management route.
To congure 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 congured 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
To view the conguration, use the show config command in INTERFACE mode.
