# Ethernet Switch with Sensors (SNMP)

## Description

This connector discovers the enclosure and Ethernet ports of a system equipped with an MIB-2 standard SNMP Agent.

This connector supersedes:

[Source](https://github.com/metricshub/community-connectors/tree/main/src/main/connector/hardware/MIB2Switch/MIB2Switch.yaml)

## Target

Typical platforms: **[Arista](platforms/arista.html), [SNMP](platforms/snmp.html)**

Operating system: **Network Device**

## Prerequisites

Leverages: **MIB-2, Entity-Sensor-MIB, SNMP**

Technology and protocols: **SNMP**

## Examples

### CLI

```batch
metricshub HOSTNAME -t network -c +MIB2Switch --snmp v2c --community public
```

### metricshub.yaml

```yaml
resourceGroups:
  <RESOURCE_GROUP>:
    resources:
      <HOSTNAME-ID>:
        attributes:
          host.name: <HOSTNAME> # Change with actual host name
          host.type: network
        connectors: [ +MIB2Switch ] # Optional, to load only this connector
        protocols:
          snmp:
            version: v2c # Read documentation for v1, v2c and v3
            community: public # or probably something more secure
```

## Connector Activation Criteria

The **Ethernet Switch with Sensors (SNMP)** connector will be automatically activated, and its status will be reported as OK if all the below criteria are met:

- An **SNMP Get-Next** on the OID `1.3.6.1.2.1.2.2.1` must return a value in the same subtree
