If you do not receive this response, check the state of CNS and TCP/IP on the MCP. If
TCPIP reports that it is currently “Networking,” query the TCPIP IDENTITY of the MCP
using the following command:
NW TCPIP IDENTITY
The first identity in the response should be similar to:
IPADDRESS 192.168.16.5 / 255.255.255.252
NP-DEVICE 210, LINEID 0,
PHYSICAL ADDRESS HEX 08000B002100
AUTOCONFIGURATION FALSE,
DUPLICATEADDRESSDETECTIONTRANSMITS 0,
VISIBLE - ,
If the IP address is different but the NP-DEVICE and LINEID match, then there might be a
mismatch in the IP address of the MCP Environment and the EVLAN adapter definition in
the I/O engine. Refer to Table 3–4 for comparison with default IP address and Line ID
values.
If the Physical Address is all zeroes (000000000000), the TCPIP connection is closed.
Determine the reason that the TCP/IP connection is closed using the NW CONN
command on the Connection Group and the Component Connection associated with the
appropriate NP based upon Table 3-3.
If the IP address is correct and the Physical Address is correct, check the configuration of
the EVLAN adapter in the I/O engine. Issue the command IPCONFIG −ALL from the same
command prompt you used to enter the PING command. You should see an adapter in the
resulting list that appears similar to the following:
Ethernet adapter Local Area Connection 29:
Connection-specific DNS Suffix . :
Description . . . . . . . . . . . : Unisys Network Services EVLAN Adapter
Physical Address. . . . . . . . . : 08-00-0B-06-22-59
DHCP Enabled. . . . . . . . . . . : No
Autoconfiguration Enabled . . . . : Yes
IPv4 Address. . . . . . . . . . . : 192.168.16.6(Preferred)
Subnet Mask . . . . . . . . . . . : 255.255.255.252
Default Gateway . . . . . . . . . :
NetBIOS over Tcpip. . . . . . . . : Enabled
The IP address should be the IOE address for the EVLAN adapter from Table 3-3, or an
alternate value assigned by the client within the same subnet as the MCP IP address for
that line. If it is not, re-configure the IP Address of the EVLAN using the MCP Console
System Editor.
If the addresses are correct but the PING command still does not work, contact your
Unisys representative for further assistance.
