USER’S GUIDE
396 CyberSWITCH
3. Verify that the remote bridge device is initiating a call to the CyberSWITCH. Since the
CyberSWITCH LAN interface has an IP address assigned with a different network number
than the one for the remote IP Host, the remote IP Host may need a proper route entry for the
local network where the CyberSWITCH is located. Make corrections to the remote IP Host
configuration.
Problem:
The remote IP Host connected to a WAN RLAN interface on the CyberSWITCH does not receive a
ping response from the local IP Host.
Action:
1.
Verify that the remote IP Host can access the LAN interface of the CyberSWITCH. If it accesses
the LAN interface, then continue with the next step.
If the remote Host is unable to access the LAN interface, refer to the preceding problem and
action.
2. Verify that the local IP Host has the route entry for the remote network with the CyberSWITCH
as the next hop. If it does, refer to
Verify IP Routing Over a LAN Connection in the System
Verification chapter.
If the local IP Host does not have the proper route entry, make corrections to the local IP Host
configuration.

Problem:
The remote router connected to a WAN UnNumbered interface on the CyberSWITCH does not
receive a ping response from the CyberSWITCH LAN interface.
Action:
1.
Have the remote router ping itself using its LAN IP address.
2. Have the CyberSWITCH ping itself using its LAN IP address.
3. Have the router ping the CyberSWITCH. If the ping is unsuccessful:
•
and no call is up, check the static route on the router
• and a call is up, check the static route on the CyberSWITCH.
