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
Use this command to modify the system settings on a switch.
Specify to enable or disable the HW batch move for MAC by group for VLAN network 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,
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,
Note: This feature is available on all platforms except AS7816-64X (F9664-C) and Z9264 platforms.
