2.13 Network Issues
When is it necessary to add a TCP/IP route?
By default, StorEdge creates a route for each connected subnet. StorEdge also allows
for the configuration of a default gateway. The local routes are used to send packets
to the attached subnets, and packets to all other IP addresses are sent via the default
gateway. This configuration works for the vast majority of networks.
A manually configured TCP/IP route is required when packets for a particular
network or host must travel through a particular network or gateway. This is usually
necessary only in cases where there are complex (multiple subnet), disjoint (not
connected to one another) networks attached to more than one interface on the
StorEdge. A manual route can also be used for performance, where it is known that
a particular network connection, other than the default gateway, is a faster route to a
particular network location. An example of this is when mirroring is used, and a
private connection is desired to a mirror system on another subnet.
How do I manually add a TCP/IP route?
1. To access this functionality, access the StorEdge via Telnet.
2. Press enter at the [menu] prompt and enter the administrator password.
3. Select option A, “Host name and Network”.
4. Select option 2, “Manage Routes”.
5. Select option 1, “Add route”
6. Select option 1, “Edit”
7. Select either Host, Network, Host Gateway or Network Gateway.
A host route defines a route to a particular host; likewise a network route defines a
route to a network. The gateway designation specifies that this route defines an
external router or gateway that should already be reachable via other defined or
default routes. When the Host or Network route is used without the gateway
designation, any gateway argument will be ignored, and a local NIC will be used as
the gateway for this route.

routes. The
