The management port lets you access the web console of a Smart Access Gateway (SAG) device from a local client. Use the SAG console to update the management port IP address, subnet mask, and gateway for an SAG-1000 device.
Prerequisites
Before you begin, ensure that you have:
An SAG-1000 device (other models are not supported)
Access to the Smart Access Gateway console
Port constraints
Port 2 is the default management port. It is reserved exclusively for web console access, cannot be modified, and cannot forward data traffic.
The default CIDR block is 192.168.0.0/24 and the default IP address is 192.168.0.1.
To connect a local client to the management port using a network cable, assign the client an IP address within the 192.168.0.0/24 range. For setup instructions, see Web configurations for an SAG-1000 device.
Update the management port settings
Log on to the Smart Access Gateway console.
Open the Device Management tab using either of these methods:
Click the ID of the target SAG instance. On the instance details page, click the Device Management tab.
Find the target SAG instance and choose
> Device Management in the Actions column.
On the Device Management tab, click Manage Management Ports.
In the Management Port Information section, click the Edit icon.
In the Manage Management Ports dialog, configure the following parameters.
Parameter Description Management Port IP IP address of the management port. MASK Subnet mask of the management port IP address. Gateway IP address of the gateway. Required only if you need to access the web console across CIDR blocks. 
Click OK.
