Using the Monitor Application

Use Monitor to troubleshoot TCP/IP stack problems. Monitor displays the contents of various caches maintained by the Cisco TCP/IP Suite.

This section includes:

See the online help for Monitor for information on printing and saving statistics, and on other things you can do with Monitor.

Starting and Stopping Monitor

To start Monitor, choose it from the Cisco Suite 100 group in the Start menu, or double-click the Monitor icon in the Cisco Suite 100 program group.

To stop Monitor, click the Exit button or choose Exit from the File menu.

Viewing the ARP Cache

The ARP cache contains IP-to-hardware-address mappings for local systems with which your workstation communicates. By viewing the contents of the ARP cache and comparing the information displayed with known IP and hardware address pairs, you can be sure that one system on the network is not using another system's IP address. Checking the ARP cache is useful when your workstation frequently loses connections when communicating with another host on the network.

To view the contents of your workstation's current ARP cache, start Monitor and either click the ARP button on the toolbar or choose the ARP Table option in the Display menu.

The ARP table includes:

To resolve network delivery problems, scan the ARP cache for the hardware address of the host with the delivery problem. If the correct hardware address does not appear in the ARP cache, it is possible that another machine is using the target host's hardware or IP address.

Viewing Buffer Statistics

Buffer statistics indicate the amount of available space for temporary storage of IP data being sent or received. To verify that all requests for memory are being honored, examine your workstation's buffer statistics.

To view buffer statistics, start Monitor and either click the Buffer Statistics button on the toolbar or choose the Buffer Statistics option in the Display menu.

The Buffer Statistics table identifies:

Occasionally, some requests for memory may be denied. This is acceptable behavior. However, if you consistently encounter denied requests for memory, please contact Technical Support.

Viewing Current Connections

The Connection Table lists your workstation's current connections.

To view your workstation's current connections, start Monitor and either click the Connection button on the toolbar or choose the Connection Table option in the Display menu.

The Connection table identifies:

Viewing the Interface Setup

The Interface table displays information about your workstation's interfaces and their configuration.

To view your workstation's current interface configuration, start Monitor and either click the Interface button on the toolbar or choose the Interface Table option in the Display menu.

The Interface table lists:

If desired, you can obtain more information about an entry in the table by double-clicking the entry. The Interface detail window appears.

The Interface detail window displays:

Viewing Protocol Statistics

The Protocol Statistics table presents detailed networking statistics for all current connections.

To view protocol statistics, start Monitor and either click the Protocol Statistics button on the toolbar or choose the Protocol Statistics option in the Display menu.

The Protocol Statistics table lists detailed statistics for all current TCP/IP connections.

Viewing the Routing Table

The Routing table identifies the hosts or networks with which your workstation is communicating and the routes being used.

To view your workstation's current routing table, start Monitor and either click the Routing Table button on the toolbar or choose the Routing Table option in the Display menu.

The Routing table lists:
