SNMP

Note: The SLC supports both MIB-II (as defined by RFC 1213) and a private enterprise MIB. The SLC product CD includes the MIB definition files for the private enterprise MIB. The private enterprise MIB provides read-only access to all statistics and configurable items provided by the SLC. It provides read-write access to a select set of functions for controlling the SLC and device ports. See the MIB definition file for details.

  1. Enter the following:

Enable Agent

Enables or disables Simple Network Management Protocol (SNMP) agent, which allows read-only access to the system. Disabled by default.

Enable Traps

Traps are notifications of certain critical events. Disabled by default. This feature is applicable when SNMP is enabled. Examples of traps that the SLC sends include:

  • Ethernet Port Link Up

  •  Ethernet Port Link Down

  • Authentication Failure

  • SLC Booted

  • SLC Shutdown

  • Device Port Logging

  • Power Supply Status

  • Sysadmin user password changed

The SLC sends the traps to the host identified in the NMS field.

NMS

When SNMP is enabled, an NMS (Network Management System) acts as a central server, requesting and receiving SNMP-type information from any computer using SNMP. The NMS can request information from the SLC and receive traps from the SLC. Enter the IP address of the NMS server. Required if you selected Enable Traps.

Communities

Read-Only

A string that acts like a password for an SNMP manager to access the read-only data the SLC SNMP agent provides. The default is public.

Read-Write

A string that acts like a password for an SNMP manager to access the read-only data the SLC SNMP agent provides and to modify data where permitted. The default is private.

Trap

The trap used for outgoing generic and enterprise traps. Traps sent with the Event trigger mechanism still use the trap community specified with the Event action. The default is public.

 

Location

Physical location of the SLC (optional). Useful for managing the SLC using SNMP. Up to 20 characters.

Contact

Description of the person responsible for maintaining the SLC, for example, a name (optional). Up to 20 characters.

Alarm Delay

Number of seconds delay between outgoing SNMP traps.

Version 3

Security

Levels of security available with SNMP v. 3.

No Auth/No: No authentication or encryption.

Auth/No Encrypt: Authentication but no encryption. (default)

Auth/Encrypt: Authentication and encryption.

Auth with

SHA: Secure Hash Algorithm

Encrypt with

Encryption standard to use:

DES: Data Encryption Standard (default)

AES: Advanced Encryption Standard
