Verify that the hardware address (MAC address) for the IP Host in the CyberSWITCH’s ARP
cache is correct. If it is not correct, verify the configuration in the IP Host.

Problem:
The remote IP Host connected to a WAN RLAN interface on the CyberSWITCH does not receive a
ping response from the WAN RLAN interface.
Action:
1.
Verify that the WAN connection is up. Use the
mc
command to check for the connection. If the
connection is up, then continue with the next step.
2.
If the connection is not up, refer to
.

Follow the steps described in the section

Problem:
The system does not display the correct message after the ping command. Instead, the system
displays the following message:
No response from <ip-address>
Action:
1.
Verify that the routing entry for the destination network exists by entering the following
administrative console command:
iproute <ip-address>
If the command returns
“
No route is available for <ip-address>
“, the routing entry
does not exist. To correct, add the routing entry using the
iproute add Manage Mode
command.
2.
Check that the system and the specified Host both have the same Subnet mask and Sub
network number for that IP address using the
ipnetif
command (Manage Mode). Correct the
Host configuration, or the system configuration (using the
iproute change
Manage Mode
command) as required.
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 CyberSWITCH 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 CyberSWITCH. The system can receive and recognize either Ethernet or SNAP type
