Host Did Not Respond Message

If the endstation or router displays this message, do the following:

Make sure that the endstation configuration includes a default gateway

definition or listens to a routing protocol.

Verify the network addresses of the source and destination devices.

If the node that did not respond is on a remote segment, verify that each

router is correctly resolving the ARP address of the next device in the

path.

If the node that did not respond is on the local segment, use the MIB

object wfIpInterfaceEntry to verify the address configuration and

interface ICMP counters.

Endstation Can Ping Devices on the Same Segment, but Cannot Ping

the Router

If the endstation can ping other devices on the same segment, but cannot ping the

local interface of the router, do the following:

Compare the endstation’s interface number, network number, and subnet

mask to those of the router’s interface. The network and subnet numbers

must be the same, except that the endstation’s subnet mask does not have

to include as many octets as the router’s subnet mask (Figure 6-1)
