Chapter 2 Monitoring the System

Monitoring with Cisco IOS Software

With in-band monitoring, network management data is sent over the same paths as user traffic. This means that any problems on the network will be more difficult to solve because collecting troubleshooting data will take longer. Using management tools is beneficial even when the internetwork is congested, failing, or under a security attack.

With out-of-band monitoring, network management data travels on different paths than user data. NMSs and agents are linked by circuits that are separate from the internetwork. The circuits can use dial-up, ISDN, or other technologies. The separate circuits can be used all the time or they can be used as backup only when the primary internetwork path is broken.

Using show Commands

You can use IOS show commands to perform a variety of tasks:

Monitor behavior during installation

Monitor normal network operation

Isolate problem interfaces, nodes, media, or applications

Determine when a network is congested

Determine the status of servers, clients, or other neighbors

Common show Commands

Commands that you are likely to use include the following:

show interfaces displays statistics for network interfaces. (For example, show interfaces serial and show interfaces ethernet.)

show buffers displays statistics for the buffer pools on the target device.

show memory shows statistics about the device’s memory.

show processes displays information about the active processes on the device.

show stacks displays information about the stack utilization of processes and interrupt routines, as well as the reason for the last system reboot.

show version displays the configuration of the system hardware, the software version, the names and sources of configuration files, and the boot images.
