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 how to add Converged Access (5760/3850/3650) to Prime Infrastructure with Simple Network Management Protocol (SNMP) v2 and v3.

Prerequisites

Requirements

Cisco recommends that you have knowledge of these topics:

  • Converged Access (5760/3850/3650) Cisco IOS® Version 3.3.x and later or Denali 16.x
  • Prime Infrastructure Version 2.0 or later

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, make sure that you understand the potential impact of any command.

Verify

Use this section to confirm that your configuration works properly.

The Cisco CLI Analyzer (registered customers only) supports certain show commands. Use the Cisco CLI Analyzer in order to view an analysis of show command output.

SNMP v2 Configuration on a Switch (Cisco IOS-XE)

Enter this command:

5760-79b#show snmp community

Community name: V2Community
Community Index: V2Community
Community SecurityName: V2Community
storage-type: nonvolatile        active

SNMP v3 Configuration on a Switch (Cisco IOS-XE)

Enter these commands:

5760-79b#show snmp user

User name: V3User
Engine ID: 80000009030068BC0C5A8F80
storage-type: nonvolatile        active
Authentication Protocol: SHA
Privacy Protocol: AES128
Group-name: V3Group

5760-79b#show snmp group
groupname: V3Group                          security model:v3 auth
contextname: <no context specified>         storage-type: nonvolatile
readview : V3Read                           writeview: V3Write                 
notifyview: <no notifyview specified>
row status: active

Note: The CLI is preferred over the GUI for SNMP v3 configuration on Converged Access for some known issues that are addressed in Cisco bug ID CSCuo52406.

Troubleshoot

This section provides information you can use to troubleshoot your configuration.

From Converged Access

The show logging command shows active packets sent to the Prime Infrastructure IP address from the WLC.

Enter these commands:

From Prime Infrastructure

SNMPWALK between devices.

Enter these commands:

PrimeInfrastructurejoker/admin# shell
Enter shell access password :
Starting bash shell ...

ade # snmpwalk -v2c -c v2community 10.201.234.36 sysUpTime
DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (238833753) 27 days, 15:25:37.53

v2community = snmp community

10.201.234.36 = WLC IP

This is the result if reachablity is there:


DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: xx.xxx
