(IP)
The
DS2000-TS
has an embedded IP router function used for connecting the
DS2000-TS
Supervisor
application to an IP network for remote operator access and for remote access to SNMP traps and operating
software downloads. The routing function may also be used by the other devices connected to the
DS2000-
TS
for routing traffic beyond their specific bridged group. The IP routing function is useful for networking
of telemetry, Telnet and other moderate bit rate applications to/from connected devices. In particular, the
routing function may be useful for allowing a single system operator to have Telnet supervisory access to a
number of remote devices which otherwise are segregated into different groups with no facility for cross-
group communications.
One key decision in configuring
DS2000-TS
IP routing is to set the scope of access to the routing function.
By default, all Ethernet ports are in one group, share the assigned system IP address and have access to the
routing function for routing outside their bridged network. Individual ports may be disabled from the IP
routing function by using the
Ethernet Switch Port Configuration
screen described Appendix A, “Port
Functions”. Routing may be further restricted using the
IP Filter
features described in “IP Filters” on page
B-7. When Port-based groups are used and you want these specific groups to participate in IP routing, IP
addresses must be assigned separately for each group, as described below. There are no default IP addresses
for groups and ports assigned to groups will not be able to route (except to the
DS2000-TS
Supervisor) until
a group IP address is assigned.
A second key decision is to define the routing protocol. By default, routed ports are defined to use RIP as
their routing protocol. The other option is Static Routing. (OSPF is not available on the
DS2000-TS
.) Each
of these requires filling in additional configuration screens.
In addition to basic IP routing, the
DS2000-TS
also supports BootP Helper and DHCP Server functions to
assist devices that are attached to the
DS2000-TS
in obtaining IP addresses and other parameters required
for the operation. BootP and DHCP functions are configured in the
DS2000-TS
as part of this IP Router
section.
IP router configuration is accessed selecting from the
Main
menu by
<2> Network
and then
<1> Router
.
shows the various router setup and status commands.
The IP addresses and routing protocols are assigned via the
<1> IP Port Configuration
submenu. The
<3>
IP Static Routes
submenu is required only when Static routing is used.
<7> DHCP
submenus are also
needed only if the respective helper/server tools are to be used. The defaults are that these services are not
enabled.
NOTE
: Although
<6> OSPF Configuration
and
<9> VRRP
appear on the Router Setup menu, they are not
available options in this version of the software.
