Configuring the Cisco 2518 SNMP Agent with SPSET

This chapter describes the System Parameter Setup program (SPSET). SPSET resides in the Cisco router/hub firmware, and is used to configure or modify the Cisco router/hub simple network management protocol (SNMP) agent.

Note You do not need to run SPSET to configure the SNMP agent. After you have configured the router card, PCbus ARP automatically assigns the agent's IP address and subnet mask.

Use SPSET to perform the following modifications:

Modify parameters.
Set serial port communication parameters.
Establish SNMP community names.
Set the SNMP managers to receive SNMP trap messages.
Save or delete router/hub management functions in NVRAM.

Running SPSET

Connect a terminal or PC to the Cisco router/hub console port as described in the chapter "Installing the Router/Hub." SPSET is designed to use ANSI screen codes, therefore to see a proper screen display, you should use a PC or VT100 terminal running ANSI emulation.

When the Cisco router/hub is powered on, the SNMP agent is configured to the values stored in SPSET. To run the SPSET program, perform the following steps:

Step 1 If the SNMP agent is running, enter Ctrl-E several times until you see the <<C>> prompt. This will stop the SNMP agent.

Note To restart the SNMP agent, enter AGENT at the <<C>> prompt.

Step 2 Enter SPSET and press Return to display the System Parameters Setup Main Menu. If you want help messages to display at the bottom of the screen, enter SPSET -HELP and press Return.

PCbus ARP

The PCbus ARP automatically assigns IP addressing to the SNMP agent. The three addresses set by ARP are as follows:

PCbus IP address
PCbus net mask
Default gateway IP address

These addresses are determined by the IP address you assign for the router PCbus interface.

Figure 6-1 illustrates a sample IP address assignment for the Cisco 2518. Note that the IP address of the SNMP agent is one greater then the IP address of the PCbus interface, and that it is on its own unique network.

Figure 6-1 Sample IP Addressing for the Cisco 2518

To verify the SNMP agent address assigned by the PCbus ARP process, perform the following steps:

Step 1 Power on the Cisco router/hub to activate the SNMP agent.

Step 2 Press Ctrl-E to escape to the <<C>> prompt.

Step 3 Run SPSET. The agent's SNMP address and subnet mask will display in the LAN PCbus interface field of the IP Setup menu. The router card's IP address is located in the default gateway field.
