Configuring Jumbo Frames

VSX supports Jumbo Frames and lets you configure up to the maximum MTU of the NIC driver.

Jumbo Frames on a Virtual System

Configure a Virtual System to enable Jumbo Frames on these interfaces types:

• Physical interface
• Bond interface
• VLAN interface

When you configure the MTU of a bond interface, the MTU of all the slave interfaces are automatically changed to the new value.

Configuring the MTU on Warp Links

• To change the MTU of Warp Links that connect to a Virtual Switch, configure the Virtual Switch settings.
• You can change the MTU of Warp Links that connect to a Virtual Router in the Virtual System settings.

Configuring the MTU on VLANs

• When you increase the MTU of a VLAN trunk, the value of the VLAN interfaces are not changed.
• The MTU of the VLAN trunk cannot be less than the value of a VLAN interface. If you increase the MTU of a VLAN interface to be larger than the VLAN trunk, the MTU of the VLAN trunk is increased to the new value for the VLAN interface.

To configure Jumbo Frames on a Virtual System:

1. Open SmartConsole.
2. From the Network Objects tree, right-click the Virtual System and select Edit.

   The General Properties window opens.

3. Click Topology.
4. Select the interface and click Edit.

   The Interface Properties window opens.

5. Configure the MTU for the interface.
6. Click OK.

Jumbo Frames on a Virtual Switch

Configure the MTU of a Virtual Switch to enable Jumbo Frames on the Virtual Systems that are connected to the Virtual Switch. When you configure the MTU of the Virtual Switch, all the related Warp Links and interfaces are automatically changed to the new value.

You cannot configure the MTU of a Warp Link from the Virtual System.

To configure Jumbo Frames on a Virtual Switch:

1. Connect with SmartConsole to the Security Management Server or Target Domain Management Server used to manage the Virtual Switch.
2. From the Gateways & Servers view or Object Explorer, double-click the Virtual Switch object.
3. From the left tree, click Topology.
4. In the Interfaces section, select the applicable interface and click Edit.
5. On the General tab, configure the MTU.
6. Click OK.
7. Publish the session.

Jumbo Frames on a Virtual Router

Configure the MTU of a Virtual Router to enable Jumbo Frames on the interfaces. To change the MTU of Warp Links, configure the settings of the Virtual System.

To configure Jumbo Frames on a Virtual Router:

1. Connect with SmartConsole to the Security Management Server or Target Domain Management Server used to manage the Virtual Router.
2. From the Gateways & Servers view or Object Explorer, double-click the Virtual Router object.
3. From the left tree, click Topology.
4. In the Interfaces section, select the applicable interface and click Edit.
5. On the General tab, configure the MTU.
6. Click OK.
7. Publish the session.
8. Install the applicable policy on the Virtual Router object.

Jumbo Frames on a Virtual System in Bridge Mode

Configure the MTU of a Virtual System in Bridge Mode to enable Jumbo Frames on the interfaces.

To configure Jumbo Frames on a Virtual System in Bridge Mode:

1. Connect with SmartConsole to the Security Management Server or Target Domain Management Server used to manage the Virtual System.
2. From the Gateways & Servers view or Object Explorer, double-click the Virtual System object.
3. From the left tree, click Topology.
4. In the Interfaces section, select the applicable interface and click Edit.
5. On the General tab, configure the MTU.
6. Click OK.
7. Publish the session.
8. Install the applicable policy on the Virtual System object.
