Configuring Hardware Batch Move in Layer 2 Table 

Note: This feature is useful in deployments with scaled-up regular VLANs, where the configuration has a lot of VLANs or MACs on a given vLAG.  This feature is disabled by default on Netvsior ONE.

The Netvsior ONE version 6.0.1 release provides support for hardware batch move mechanism to accelerate the MAC programming in Layer 2 table in a switch. 

You can enable the hardware batch move feature by using the batch-move-mac-hw-group-for-vlan-only  option in the  system-settings-modify command.   If enabled, this feature uses an internal switch specific construct called  portgroups to identify and move the MACs between  a vLAG and Cluster communication ports when the vLAG comes up or goes down in a VLAN network.

Caution: You must enable this feature only for scaled-up VLAN or MAC environments.

When disabled (this feature is disabled by default), the MAC move mechanism uses the conventional software batch move process, which has an acceptable level of traffic loss during the MAC move process in a VLAN or VLAN-VXLAN network. The software batch move feature supports hybrid  mechanism (that is, software batch move in VLAN network, VXLAN network, and VLAN-VXLAN network)  that can accelerate the MAC programming in Layer 2 table of an underlying switch.

To elaborate, when the hardware  batch move feature is enabled or disabled:

• For VLAN only networks - uses the Hardware batch move feature if enabled. 
• For regular VXLAN only configurations - uses the Software batch feature.
• For a combination of regular VLAN and VXLAN- VLAN network -  uses hybrid method. That is, regular VLAN network uses  hardware batch move  if the feature is enabled. The VXLAN-VLAN network uses software batch move.
• When the hardware batch move feature is disabled, both regular VLAN  and VXLAN-VLAN network uses the software batch move as the default option.

To configure the hardware batch move, use the system-settings-modify command with the batch-move-mac-hw-group-for-vlan-only  command option.

Note: When you enable the feature ,  you must reboot the switch for the changes to take effect.

To enable the hardware batch move feature:

CLI (network-admin@switch1) > system-settings-modify  batch-move-mac-hw-group-for-vlan-only|no-batch-move-mac-hw-group-for-vlan-only 

To verify if the hardware batch move is enabled or not on a switch, use the command:

CLI (network-admin@switch1) > system-settings-show

An example to enable the hardware batch move feature and view the details is provided below:

CLI (network-admin@switch1*) > system-settings-show format batch-move-mac-hw-group-for-vlan-only,

batch-move-mac-hw-group-for-vlan-only: off

CLI (network-admin@switch1*) > system-settings-modify batch-move-mac-hw-group-for-vlan-only

Modified settings require a REBOOT to take effect.

CLI (network-admin@cham-colo-1*) > switch-reboot

CLI (network-admin@cham-colo-1*) > system-settings-show format batch-move-mac-hw-group-for-vlan-only,

batch-move-mac-hw-group-for-vlan-only: on

Note: This feature is available on all platforms except AS7816-64X (F9664-C) and Z9264 platforms.
