Chapter 8: Configuring IP Interfaces for the SSR

6. Enter the name of the interface in the Interface Name box. Then either select Up to
enable the interface or select Down to disable it.
7. Enter the number of bytes you want to specify for the Maximum Transmission Unit
(MTU).
The MTU is the largest packet size that the SSR can transmit on the network via the
interface. Any messages larger than the MTU are divided into smaller packets before
being sent. You should set the MTU equal to the smallest MTU of all the networks
between the SSR and a message's final destination. Otherwise, transmission speed
slows down because the packets have to be fragmented.
8. Set the output MAC encapsulation you want associated with the interface by selecting
one of the following from the Output MAC Encapsulation drop-down list:
– ethernet_II (the default)
– ethernet_snap
9. Click Next. Then enter the IP address, subnetwork mask, and broadcast address of the
interface in the panel that appears.
You can specify the IP address and subnetwork mask values using the traditional
format (example: 10.1.2.3/255.255.0.0).
Specifying a broadcast address is optional.
