USRobotics NETServer/16 Switch User Manual


 
LAN-to-LAN Routing 6-23
Protocol
Select the protocol to be used for the connection (PPP or SLIP).
Use the following command:
set user <user name> protocol <
ppp
|
slip
>
IPX LAN-to-LAN routing requires the PPP protocol. If you have
assigned an IPX Network Number, the NETServer will set this
to PPP automatically.
Netmask
Use the following command to tell the NETServer the remote
network’s IP subnet mask:
set user <user name> netmask <netmask>
MTU
The Maximum Transmission Unit specifies the size of the largest
packet that may be received from the remote location. IPX
connections will discard larger packets. IP connections will
fragment larger packets. Normally, this should be set to the
largest value possible. However, an IP connection using multi-
line load balancing may benefit from a smaller MTU (see Step 3
of Location setup, earlier in this chapter).
Valid PPP MTUs range from 100 to 1500 (default is 1500). Note
that PPP allows remote systems to negotiate a smaller MTU if
needed. Valid SLIP MTUs range from 100 to 1006 (default is
1006).
set user <user name> mtu <value>
IPX LAN-to-LAN routing requires an MTU of 1500 If you have
assigned an IPX Network Number, the NETServer will set this
to 1500 automatically.
