Verifying Basic Setup

Note The information herein applies to the Cisco AS5350, Cisco AS5400, and Cisco AS5400HPX universal gateways. Note that the latter requires use of Cisco IOS release 12.2(2)XB or later.

This chapter details the tasks required to verify that your basic system components are functioning normally:

•Analyzing the System Boot Dialog

•Checking the Initial Running Configuration

•Investigating Memory Usage

•Inspecting CPU Utilization

Analyzing the System Boot Dialog

The Cisco AS5350 and Cisco AS5400 have a specific boot sequence. To view the boot sequence through a terminal session, you must have a console connection to the gateway before it powers up.

Note If you observe no messages on the console port, check that the baud rate is configured correctly. The Cisco AS5350 and Cisco AS5400 console port can support a baud rate up to 115200.

The following boot sequence occurs. Step numbers and comments are inserted in the example to describe the boot sequence.

Step 1 In the following segment, the gateway decompresses the system boot image, tests the NVRAM for validity, and decompresses the Cisco IOS image.

Step 3 Because the gateway has never been configured, it cannot find a startup-config file. Therefore, the software asks, "Would you like to enter the initial configuration dialog? [yes/no]"

Enter no. In this example, the Cisco IOS software is configured manually. The automatic setup script is not used. Configuring the Cisco IOS software manually develops your expertise.

Enter yes to terminate autoinstall.

Step 4 This example shows the LAN interfaces and the slots in which port cards are not inserted. The universal-port-card (formerly called NextPort) module firmware version is displayed (version 1.1.6.81). The gateway attempts to switch to a better clock source but does not find a suitable source because the T1s are not yet configured.

The Cisco AS5350 or Cisco AS5400 displays every asynchronous interface it recognizes. Therefore, if your system has a large number of asynchronous interfaces, the running-configuration will be very long. To aggregate the asynchronous interfaces, you must assign them to a Group-Async Interface using the command group-range. See the "Configuring the Asynchronous Group Interface" section.

Group-async interfaces are templates used to control the configuration of multiple asynchronous interfaces on the gateway. Each asynchronous interface corresponds to one of the modem lines and uses the same number as its corresponding line. Configuring the asynchronous interfaces as a group-async saves you time and configuration file size.

Investigating Memory Usage

Use the show memory summary command to:

•Understand how memory is used for different processor and I/O memory processes.

•Identify memory fragmentation and memory leaks.

–Memory leak—Memory that is not released back to the processor. Memory leaks are indicated by steady decreases of free memory. However, the preferred way to track memory leaks is to monitor the FreeMem variable in the OID MIB (object-identifier management information base).

–Memory fragmentation—Indicated by the largest block of memory not being equal to the lowest block. Fragmentation increases as the numbers grow further apart.
Router# show memory summary
                Head    Total(b)     Used(b)     Free(b)   Lowest(b)  Largest(b)
Processor   61952B00   107664640    24210716    83453924    82827184    82866768
      I/O   40000000    67108880    28952352    38156528    38156528    38156412
.
.
.
The sum of the used and free memory equals the total memory. Most of the show memory summary command output has been removed for brevity.

Note Do not enter the show memory summary command with the terminal length 0 command enabled. If you do, many screens of output might interrupt your session.

Note To learn more about management information bases (MIBs), see the online references at
http://www.cisco.com/univercd/cc/td/doc/product/software/.
Select your Cisco IOS release and search under new feature documentation.

Inspecting CPU Utilization

Enter the show process cpu command and then the show process cpu history command to investigate high CPU utilization. High utilization causes network performance problems. For example, knowing when the router is running at over 50% utilization is critical. The router might start dropping packets if an unexpected traffic burst comes through or if Open Shortest Path First (OSPF) is recalculated. Fast switching can also be used to reduce CPU utilization.

The show processes cpu history command displays in ASCII graphical form the total CPU usage on the router over a period of time: one minute, one hour, and 72 hours, displayed in increments of one second, one minute, and one hour, respectively. Maximum usage is measured and recorded every second; average usage is calculated on periods over one second.
