TCPCON

Purpose

Use at the server console to

• Monitor activity in the TCP/IP network segments of your internetwork
• View configuration and statistics information about the following TCP/IP protocols: IP, ICMP, UDP, TCP, OSPF, and EGP
• View IP routes known to a TCP/IP node
• View network interfaces supported by a TCP/IP node
• Access the trap log maintained by SNMPLOG (local systems only)
• Use Simple Network Management Protocol (SNMP) over TCP/IP or IPX^TM to access TCP/IP information in any remote protocol stack supporting the TCP/IP Management Information Base (MIB)

Syntax

[LOAD] TCPCON

Using TCPCON

• By default, TCPCON monitors and gathers information from the local NetWare^® TCP/IP node.

  You can, however, access another TCP/IP node on your internetwork if you know the symbolic hostname or host IP address of that node.

• When you load TCPCON, the TCPCON main screen appears:
  

• The top of the main screen displays a summary of statistics for the selected host, as follows:

  Field	Explanation
  Host	Symbolic host name or IP address of the selected TCP/IP host (or server name if accessing a remote node using IPXTM) being queried. This is the host specified in SNMP Access Configuration in the Available Options menu.
  Uptime	Amount of time that has elapsed since the selected host was last initialized.
  System	Brief description of the selected host.
  IP Received	Number of IP datagrams received from all interfaces, including those received in error.
  IP Sent	Number of datagrams sent to IP for transmission. This number does not include datagrams forwarded by this host.
  IP Forwarded	Number of IP packets forwarded from one node to another. This field displays the value Disabled if this host is not configured to be an IP router.
  TCP Received	Number of TCP segments received, including those received in error.
  TCP Sent	Number of TCP segments sent, excluding those containing retransmitted data.
  TCP Connections	Number of currently established TCP connections.

• The Available Options menu on the main screen allows access to additional features of TCPCON, as follows:

  Option	Use to
  SNMP Access Configuration	View and modify TCPCON options.
  Protocol Information	View protocol information for the selected host.
  IP Routing Table	View IP routers known to the selected host.
  Statistics	View TCP/IP statistics.
  Interfaces	View the network interfaces supported by the selected host.
  Display Local Traps	View the local SNMP trap log maintained by SNMPLOG.NLM.
