1.
Verify that the routing entry for the destination network exists by entering the following
console command:
console command:
iproute <ip-address>
2.
If the command returns “
No route is available for <ip-address>,
“the routing
entry does not exist. To correct, add the static routing entry using the
iproute add

Mode command.
3.
Check that the CyberSWITCH and the specified Host both have the same Subnet mask and Sub
network number for that ip-address using the
network number for that ip-address using the
ipnetif
Manage Mode command. Correct the
Host configuration, or the system configuration (using the
iproute change

command) as required.
4.
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
so that the ARP entry is updated. Use the
ip arp
command to look at the ARP cache entries.
(This command is described in the
chapter.) If the ARP cache entry for the
Host does not exist, verify that the Host is operational and that the CyberSWITCH and the Host
are both physically connected to the same LAN segment.
are both physically connected to the same LAN segment.
5.
If the ARP cache entry exists for the Host, check that the IP Host has the same encapsulation
type as the CyberSWITCH. The CyberSWITCH can receive and recognize either Ethernet or
SNAP type encapsulations. Correct the IP Host or CyberSWITCH configuration (using
CFGEDIT) for encapsulation type.

6.
Try to ping the Host from another device on the LAN. If this is also unsuccessful, this may
indicate a problem with the Host.
