Dell Networking OS installs a next hop that is on the directly connected subnet of current IP address on
the interface (for example, if interface TenGigabitEthernet 1/1 is on 172.31.5.0 subnet, Dell
Networking OS installs the static route).
Dell Networking OS 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 te 1/1 has ip
address on subnet 2.2.2.0 and if 172.31.5.43 recursively resolves to 2.2.2.0, Dell Networking OS installs the
static route.
• When the interface goes down, Dell Networking OS withdraws the route.
• When the interface comes up, Dell Networking OS re-installs the route.
• When the recursive resolution is "broken," Dell Networking OS withdraws the route.
• When the recursive resolution is satisfied, Dell Networking OS 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 route static 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

IPv4 Path MTU Discovery Overview

This functionality is supported on the S4820T platform.
The size of the packet that can be sent across each hop in the network path without being fragmented is
called the path maximum transmission unit (PMTU). This value might vary for the same route between
two devices, mainly over a public network, depending on the network load and speed, and it is not a
