Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Introduction

This document describes the steps on Object Identifiers (OIDs) within the Secure Web Appliance (SWA).

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

  • SWA Administration
  • A fundamental understanding of networking principles
  • Fundamentals of Simple Network Management Protocol (SNMP)

Cisco recommends that you have:

  • A Physical or Virtual SWA Installed
  • Administrative Access to the SWA Command-Line Interface (CLI)

Components Used

This document is not restricted to specific software and hardware versions.

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Problem

For network administrators and IT professionals working with Cisco Secure Web Appliance (SWA) and Security Management Appliance (SMA), the snmpwalk command is a crucial tool. This command assists in retrieving OID values, which are necessary for effective monitoring and management.

While snmpwalk is readily available on macOS, additional setup is required on Windows and Linux systems, which can be a barrier for some users.

To overcome this challenge, Cisco Engineers tested snmpwalk commands in lab environments and have provided the outputs for reference. This resource is intended to support users who face setup restrictions by offering these reference outputs, aiding in the management of their SWA and SMA environments.

OIDs play a vital role in network management, allowing for the identification and interaction with various network elements. By leveraging snmpwalk, users can efficiently obtain and interpret values associated with important OIDs, enhancing the monitoring and management of SWA and SMA systems. This guide explains how to use snmpwalk to access key OID values, which in turn boost your network management capabilities.

Solution

You can find a sequence of OID names, snmpwalk command syntax, and sample outputs.

View OIDs

Cisco does not provide an OID list for content security appliances. You can convert the MIB file to view OID using a third-party MIB Browser Application such as Paessler MIB Imported. You can download a third-party application from Paessler


These are the steps to view OIDs:

1. Download the MIB browser software.
2. Import the MIB file into your application (the latest MIB files can be download from Cisco Secure Web Appliance Product Page).

Download MIB FilesImage: Download MIB Files

3. Import The MIB File to your application.

Note: You must download and import the SMI MIB and the Web MIB.


4. You can view all OIDs defined in the MIB files.

Note: Be aware that certain OIDs, such as those related to the Fan Table and Power Supply do not return outputs in a virtual environment when the hardware component is absent. This is because these hardware components are not present in virtual appliances.
