wfIpBase.wfIpBaseZeroSubnetEnable.0 = 2

wfIpBase.wfIpBaseEstimatedNetworks.0 = 0

wfIpBase.wfIpBaseHosts.0 = 81

wfIpBase.wfIpBaseEstimatedHosts.0 = 0

wfIpBase.wfIpBaseDefaultOverSubnetEnable.0 = 2

wfIpBase.wfIpBaseMaxPolicyRules.0 = 32

3. Check the values of the following statistics twice in the

wfIpInterfaceEntry object. Compare them to determine whether IP is

currently receiving and transmitting packets, and generating errors:

• The reception and transmission statistics

If the reception or transmission statistics do not change, do the following:

— Check the reception and transmission statistics of the other protocols

associated with the same connector and the same slot.

— Try disabling and enabling IP, and watch the log messages to

determine why the connection will not come up.

• The error statistics

4. Make sure that the next hop and network you are trying to reach are in

the routing table entries.

5. Verify the conﬁguration parameters.

6. Use Packet Capture and a network analyzer to check the segments

involved in the problem.

Refer to one of the following sections if it pertains to your problem:

•“Troubleshooting Telnet, FTP, and TFTP”

•“Ping Does Not

Work”

•“T

roubleshooting Routing Information Protocol (RIP)”

•“T

roubleshooting Open Shortest Path First (OSPF)”

Caution: Do not do this if it could be disruptive to the network.
