Managing Network Bandwidth from the Console Operating

System

/proc/vmware/filters/status

This file contains network filtering status information, including a list of all available

filter classes and, for each virtual machine with attached filters, its list of attached filter

instances. Read the file with cat to see a quick report on network filtering status.

/proc/vmware/filters/xmitpush

Command file used to add a new transmit filter instance to a virtual machine. Writing

<id> <class> [<args>] to this file attaches a new instance of filter <class>

instantiated with <args> to the virtual machine identified by <id>.

/proc/vmware/filters/xmitpop

Command file used to detach a transmit filter from a virtual machine. Writing <id> to

this file detaches the last filter attached to the virtual machine identified by <id>.

/proc/vmware/filters/xmit

This directory contains a file for each active filter instance. Each file named

<class.n> corresponds to the <n>th instance of filter class <class>.

Reading from a file reports status information for the filter instance in a class-defined

format. Writing to a file issues a command to the filter instance using a class-defined

syntax.

Note: The current release allows only a single network packet filter to be attached to

each virtual machine. Receive filters are not implemented in this release.

Traffic Shaping with nfshaper

You can manage network bandwidth allocation on a server from the VMware

Management Interface or from the console operating system’s command line.

Using a Web browser, you may change settings from the Resource Editor page of the

management interface. Be sure the virtual machine you want to change is powered

on. Then, on the server’s Overview page, click Manage Resources. The Resource

Monitor page appears. Click Edit Resources under the name of the virtual machine for

which you want to change settings. Enter the desired settings, then click Save

Changes.

You must log in as root in order to change resource management settings using

either the management interface or the command line.

The shaper implements a two-bucket composite traffic shaping algorithm. A first

token bucket controls sustained average bandwidth and burstiness. A second token
