Troubleshooting Routers

7-8

If the ping attempts fail, but the number of transmitted requests increments,

the workstation has a path to the requested address, but failed to receive a

response. Do the following:

a. Verify that the router interface has a path to the PC.

b. Verify that the segment on which the workstation is located does not

contain duplicate IP addresses.

c. Issue the Technician Interface get wfIpInterfaceEntry.45.* to display

the number of ICMP echo requests the interface received for that IP

address.

3. After the workstation can ping the local router interface and receive a

response, ping another interface on the router to determine whether the

end node knows how to get off the local network. If this test fails, check

the routing table on the UNIX workstation.

Target Does Not Respond (or Similar Message)

The destination node of the ping request failed to respond. To determine whether

the pinged node is in the local ARP cache, issue the

arp -a command. Most UNIX

workstations display the current ARP cache in response to this command.

If the MAC address of the station pinged unsuccessfully is in the ARP cache,

check the pinged interface’s wfIpInterfaceEntry statistics.

If the MAC address is not in the ARP cache, do the following:

1. Enter the following command to check the workstation’s interface

deﬁnition:

ifconﬁg -a

The workstation displays all of the assigned IP addresses and subnet masks.

2. From other nodes on the segment, ping the router’s interface.

3. From other nodes on the segment, ping the workstation from which you

are trying to establish a Site Manager connection.
