High Availability

Configuring the ADX in symmetric mode

In the symmetric mode, both the ADX devices handle SLB traffic, and both the devices are active

for the same VIP. This mode is supported only on chassis systems.

NOTE

Symmetric active-active mode is supported in both switch code and router code.

Configuring symmetric mode on the device involves the following configurations:

• Setting up a symmetric port

• Setting up a VIP group

Setting up a symmetric port

You can specify a synchronization link (port and VLAN ID) for symmetric SLB to automatically detect

the synchronization link failure and revert to the dynamic detection of the communication links.

To configure the symmetric active-active mode on a device, perform the following steps within the

Configure tab:

1. Click System on the menu bar.

2. From the sidebar, select High Availability, and then select Symmetric.

The Symmetric page is displayed, as shown in Figure 10.
