VM Policy Bandwidth Control

Note – VM policy bandwidth control is supported only when the switch is operating with the Default deployment profile (see “Deployment Profiles” on page 147). If using the Routing profile, VM policy bandwidth control commands will not be available.

In a virtualized environment where VEs can migrate between hypervisors and thus move among different ports on the switch, traffic bandwidth policies must be attached to VEs, rather than to a specific switch port.

VM Policy Bandwidth Control allows the administrator to specify the amount of data the switch will permit to flow from a particular VE, without defining a complicated matrix of ACLs or VMAPs for all port combinations where a VE may appear.

VM Policy Bandwidth Control Commands

VM Policy Bandwidth Control can be configured using the following configuration commands:

RS G8124(config)# virt vmpolicy vmbwidth <VM MAC><index><UUID>

<IPv4 address><name> ?

(Set the VM to switch rate)

txrate

<committed rate> <burst> [<ACL number>]

bwctrl

 

(Enable bandwidth control)

Bandwidth allocation can be defined for transmit (TX) traffic only. Because bandwidth allocation is specified from the perspective of the VE, the switch command for TX Rate Control (txrate) sets the data rate to be sent from the VM to the switch.

The committed rate is specified in multiples of 64 kbps, from 64 to 10,000,000. The maximum burst rate is specified as 32, 64, 128, 256, 1024, 2048, or 4096 kb. If both the committed rate and burst are set to 0, bandwidth control will be disabled.

When txrate is specified, the switch automatically selects an available ACL for internal use with bandwidth control. Optionally, if automatic ACL selection is not desired, a specific ACL may be selected. If there are no unassigned ACLs available, txrate cannot be configured.
