Entering static routes

Note: When entered in the Ethernet TAP probe, static routes are not updated automatically. You must update these routes if changes in network topology affect the static routes.

Before entering static routes, make a map of all gateway paths between the Ethernet TAP probe, as starting point, and each workstation that must have access to it.

To enter static route or default gateway

At the core> prompt, use the netparam command to enter the first host/gateway pair:
```
netparam add_route host_ip gateway_ip hop_#
```
Wait for the core> prompt between each netparam entry.

Note: host_ip can identify an individual host or a network serving multiple hosts. The gateway_ip is the first gateway the Ethernet TAP probe crosses when communicating with the destination host. The hop_# is the decimal number of gateways between the Ethernet TAP probe and the destination host. For more information on the netparam command, see Ethernet TAP probe setup utility commands topic.
Add routes until all destination hosts or networks are defined.

When the core> prompt returns, reset the Ethernet TAP probe by cycling power, or by entering the reset command.

Static route example

Figure below shows three class "C" networks joined together by a single IP router, making each Ethernet TAP probe accessible from three workstations (elmer, tweety, and brutus).

No static routing information is required to make an Ethernet TAP probe accessible from a workstation local to it on a network. For example, the Ethernet TAP probe goofy on network 198.9.230.0 communicates directly with workstation elmer.

When static routing is used, a routing entry is required on an Ethernet TAP probe for each workstation on a non-local network that accesses it. The Ethernet TAP probe goofy requires two entries, for workstation tweety on network 198.9.231.0 and workstation brutus on network 198.9.232.0.

Each static route entry is made using a netparam command and consists of a network address and a host address. The netparam commands for the static route entries for Ethernet TAP probe goofy are:


   netparam add_route 198.9.231.0 198.9.230.1 1   

   netparam add_route 198.9.232.0 198.9.230.1 1

Figure 1. Three Class C networks connected by a single router

Each of the three Ethernet TAP probe hosts must have a static route entry for each remote workstation that accesses it.
