Summary

This document provides information about the Arista - Dynamic Vlan Assignment implementation for VSM.

Status of Driver	APPROVED
Component for Driver	GADGETSERVER
Release (Build) of Component	vsmGadgetserver 5.4.x (2017)
Revision of Implementation	1.0

Name/Type of 3rd Party API	Arista eAPI
Version of 3rd Party API	1.0.0.2
Additional 3rd Party information

Connection

Connection Type	TCP/ IP
Default Port

The stream type must be set to Virtual.

Supported Features

The user can assign a specified switch interface to a specfied vlan via 1:N Matrix.

Supported Commands

Command 1	enable
Command 2	configure
Command 3	show vlan
Command 4	show interfaces description
Command 5	interface
Command 6	switch access vlan

Configuration Details

eApi must be enabled on all controlled switches via Terminal commands:

enable

configure terminal

management api http-commands

[no] shutdown

[no] protocol https [port ]

[no] protocol http [port ]

All contolled switches must be configured with identical Vlan indices. Ethernet interfaces must be configured via:

switchport

switchport mode access

vsmGadgetserver

Since this protocol is using the Virtual Streamtype, the protocol applies a default value (“Settings”) to the Address field to enable the communication.

At the first stage this protocol needs the uri, user name and password for all controlled Arista switches on the network. Please edit the Switches in the following format:

IpAddress:Port;UserName;Password

The protocol needs a valid Vlan index in option Blind to perform a disconnect.

The option System Mapping holds the mapping file of this protocol wich will be used to map the interfaces(targets)/vlans(sources) to the protocol matrix. Each switch supports up to 64 targets per device. Please download, edit and upload the .xml file.

The configured VLans will be automatically added to the mapping file as sources. For the target mapping the user must enter the used interfaces to the corresponding switch regions:

 <indexMappingRegion>
      <name>10.1.234.66:80</name>
      <offset>0</offset>
      <usage>Target</usage>
      <children>
        <indexMapping>
          <identifier>Ethernet3/10</identifier>
          <index>0</index>
        </indexMapping>
        <indexMapping>
          <identifier>Ethernet3/11</identifier>
          <index>1</index>
        </indexMapping>
      </children>
    </indexMappingRegion>

XML

The <offset> tag defines the switch offset on the matrix multiplied by 64. An ethernet interface must be enclosed by the <indexMapping> tags. <identifier> is the inteface name and <index> is the index on the matrix plus the offset calculation.

Known Issues

Since the protocol must open connections to different devices, we currently cannot provide a useful protocol operation state(Valid,Connected,Disconnected). As soon as the first switch is detected as online, the operation state will switch to valid.
