SNMP Configuration and Troubleshooting

VEGA act as SNMP Agent as it collects the management information database from the device locally and makes it available to the SNMP manager, when it is queried for. It stores and retrieves management information as defined in the MIB. 
Also signals an event to the manager in form of traps when required.

Configuration

SNMP configuration VEGA can easily be achieved from VEGA GUI.

All SNMP relates configuration is present within VEGA GUI > Expert Config > Logging > SNMP as shown below:

Open

SNMP configuration on VEGA can mainly be divided in to three different parts:

1. General SNMP Configuration

2. SNMP Manager Configuration

3. SNMP Communities Configuration

General SNMP Configuration

As the name suggest there are the general SNMP configuration that is must to be configured in order to use SNMP.

There are mainly four General SNMP Configuration:

1. LAN Profile
   LAN Profile as present within SNMP configuration section is configured in order to tell vega which lan profile need to be used in order to establish connection between VEGA (SNMP Agent) and SNMP Manager

2. Password
   This mainly configures the device password i.e. required for authentication in case of SNMPv3

3. Contact
   This mainly configures the location of the device i.e. VEGA.

4. Location
   This mainly configures the location of the device i.e. VEGA

General SNMP Configuration is shown as given below:

VEGA GUI > Expert Config > Logging > SNMP > SNMP Configuration

SNMP Managers Configuration

As the name suggest this configuration is mainly with respect to SNMP Manager that needs to be configured for VEGA

There are mainly four SNMP Manager Configuration:

1. IP
   This mainly configures the ip of the SNMP Manager. It is configured to restrict SNMP services only to this IP address.

2. Subnet
   This mainly configures the mask to identify significant part of manager’s IP address to check.

3. Community
   This mainly configures the community name that is used by SNMPv3/SNMPv2c/SNMPv1.

4. Support snmpV3
   This mainly enable/disable support for SNMPv3 on VEGA.

SNMP Managers Configuration is shown as given below:

VEGA GUI > Expert Config > Logging > SNMP > SNMP Managers

SNMP Communities Configuration

As the name suggest this mainly configures the communities as used by different SNMP version i.e. SNMPv1/SNMPv2c/SNMPv3.

SNMPv1 and SNMPv2 use communities to establish trust between managers and agents. Most agents support three community names, one each for read-only, read-write and trap. 

These three community strings control different types of activities.

1. The read-only community applies to get requests.

2. The read-write community string applies to set requests.

3. The trap community string applies to receipt of traps. 

SNMPv3 also uses community strings, but allows for secure authentication and communication between SNMP manager and agent

There are mainly four SNMP Communities Configuration:

1. Name
   This mainly configures the community name that is used by SNMP Manager

2. Get
   This mainly configured the get command/read permission for that community i.e. if this configuration is set then SNMP Manager using its respective community is allowed to get response for SNMP Get/read command.

3. Set
   This mainly configured the set command/write permission for that community i.e. if this configuration is set then SNMP Manager using its respective community is allowed to get response for SNMP Set/write command.

4. Traps
   This mainly configured the traps/indication permission for that community i.e. if this configuration is set then SNMP Agent i.e. VEGA is allowed to send traps/indication to its respective SNMP manager.

SNMP Communities Configuration is shown as given below:
