Static Route

52.1 Static Routing Overview

This chapter shows you how to configure static routes.
The Switch uses IP for communication with management computers, for example using HTTP, Telnet, SSH,
or SNMP. Use IP static routes to have the Switch respond to remote management stations that are not
reachable through the default gateway. The Switch can also use static routes to send data to a server
or device that is not reachable through the default gateway, for example when sending SNMP traps or
using ping to test IP connectivity.
The Switch usually uses the default gateway to route outbound traffic from computers on the LAN to the
Internet. To have the Switch send data to devices not reachable through the default gateway, use
static routes.
For example, the next figure shows a computer (A) connected to the Switch. The Switch routes most
traffic from A to the Internet through the Switch's default gateway (R1). You create one static route to
connect to services offered by your ISP behind router R2. You create another static route to
communicate with a separate network behind a router R3 connected to the Switch.
Figure 218 Example of Static Routing Topology
N1
This figure shows a Telnet session coming in from network N1. The Switch sends reply traffic to default
gateway R1 which routes it back to the manager's computer. The Switch needs a static route to tell it to
use router R2 to send traffic to an SNMP trap server on network N2.
