Cabletron Systems CSX1000 manual IP Filters, IP Routing Over a WAN Unnumbered Interface Connection

USER’S GUIDE

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.

IP ROUTING OVER A WAN UNNUMBERED INTERFACE CONNECTION

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.

IP FILTERS

Problem:

IP Filters are not correctly discarding packets.

Action:

Check to see if the filters are properly configured:

1.From Manage Mode, issue the ipfilt command. Check the configured packet types, as well as the configured filters:
