## SYNOPSIS

```
 # Let SNMP::Info determine the correct subclass for you.
 my $arista = new SNMP::Info(
                        AutoSpecify => 1,
                        Debug       => 1,
                        # These arguments are passed directly to SNMP::Session
                        DestHost    => 'myswitch',
                        Community   => 'public',
                        Version     => 2
                        )

## DESCRIPTION

Subclass for Arista Networks EOS-based devices

### Inherited Classes

- SNMP::Info::Aggregate

  - SNMP::Info::Layer3

  - SNMP::Info::MAU

  ### Required MIBs

- *ARISTA-PRODUCTS-MIB*

  - Inherited Classes' MIBs

  See "Required MIBs" in SNMP::Info::Layer3 for its own MIB requirements.

  See "Required MIBs" in SNMP::Info::Aggregate for its own MIB requirements.

  See "Required MIBs" in SNMP::Info::MAU for its own MIB requirements.

## GLOBALS

These are methods that return scalar values from SNMP

- $arista-\>**vendor()**

  Returns 'arista'

- $arista-\>**model()**

  Tries to reference `$arista`-\>**id()** to one of the product MIBs listed above

  Removes 'arista' from the name for readability.

- $arista-\>**os()**

  Returns 'EOS'

- $arista-\>**os\_ver()**

  Grabs the os version from `"sysDescr"`

### Global Methods imported from SNMP::Info::Layer3

See documentation in "GLOBALS" in SNMP::Info::Layer3 for details.

### Global Methods imported from SNMP::Info::MAU

See documentation in "GLOBALS" in SNMP::Info::MAU for details.

## TABLE METHODS

These are methods that return tables of information in the form of a reference to a hash.

- $arista-\>**i\_duplex\_admin()**

  Returns info from *MAU-MIB*

- $arista-\>**i\_speed\_admin()**

  Returns info from *MAU-MIB*

- $arista-\>**lldp\_if()**

  Returns the mapping to the SNMP Interface Table.

- "agg\_ports"

  Returns a HASH reference mapping from slave to master port for each member of a port bundle on the device. Keys are ifIndex of the slave ports, Values are ifIndex of the corresponding master ports.

### Table Methods imported from SNMP::Info::Layer3

See documentation in "TABLE METHODS" in SNMP::Info::Layer3 for details.

### Table Methods imported from SNMP::Info::MAU
