• For static routes: refer to Configuring IP Network System Static Routes in the Configuring IP
Network Information chapter.
• For downloading configuration files: refer to Downloading Configuration Updates in the
Exporting Configuration Files chapter.
2. Check that the system and the specified Host both have the same Subnet mask and Sub
network number for that IP address using SFVRA-CFG. Correct the Host configuration, or the
system configuration as required. To do this:
a. If it is not already running, start up SFVRA-CFG.
b. From the toolbar, select Functions then click on IP Network, then on Subnets, or click
on the toolbar.
c. Double click on the particular subnet that applies to the system.
d. Check the subnet's mask and network number. Compare the values to the host's
configuration.
If you change the system's mask and/or subnetwork number instead of the host's, you will
need to configure a new subnet, and associate the system with the new subnet. This is
because you cannot change these values for the subnet once it has been configured. Refer
to the SFVRA-CFG documentation if you need to do this.
For more detailed instructions, refer to the following sections in the SFVRA Configuration
Manager User's Guide:
• For static routes: refer to Configuring IP Network Subnet Information in the Configuring IP
Network Information chapter.
• For downloading updated configuration files: refer to Downloading Configuration Updates in
the Exporting Configuration Files chapter.
3. Verify that the ARP entry for the specified IP address exists. As required, ping from the IP Host
so that the ARP entry is updated. Use the ip arp console command to look at the ARP cache
entries. If the ARP cache entry for the Host does not exist, verify that the Host is operational
and that the SmartSwitch Remote Access Module and the Host are both physically connected
to the same LAN segment.
4. If the ARP cache entry exists for the Host, check that the IP Host has the same encapsulation
type as the SmartSwitch Remote Access Module. The system can receive and recognize either
Ethernet or SNAP type encapsulations. Correct the IP Host or system configuration (through
SFVRA-CFG) for encapsulation type. To do this for SmartSwitch Remote Access Module:
a. If it is not already running, start up SFVRA-CFG.
b. From the toolbar, select Functions then click on IP Network, then on Subnets, or click
on the toolbar.
c. Double click on the particular subnet that applies to the system.
