    The Sites page appears.

  2. Click the name of the site for which you want to add the LAN segment.

    The Site-Name page appears.

  3. Click the add icon (+) on the LAN tab.

    The Add LAN Segment page appears.

  4. Complete the configuration settings according to the guidelines provided in Table 1.Note

    You are returned to the Site-Name page, where the LAN segment that you added is displayed.

Table 1: Add LAN Segment Settings

Field

Description

Name

Enter a unique string of alphanumeric characters. No spaces are allowed and the maximum length is 15 characters.

Type

Select the type of LAN segment:

  • Directly Connected—Indicates that the LAN segment is directly connected to the site. This is the default.

  • Dynamic Routed—Indicates that the LAN segment is not directly connected to the site and is reachable by using a dynamic route. If you select this option, you must specify the dynamic routing information.

    Note: You can configure dynamically routed LAN segments only for gateway sites.

Ports

Select one or more port numbers from the list depending on the connection plan that you previously specified.

VLAN ID

Enter the VLAN ID for the LAN segment.

Range: 1 through 4094.

IP Address Prefix

Enter the IP address prefix for the LAN segment; for example, 192.0.2.8/24.

Department

Select a department to which the LAN segment is to be assigned. You group LAN segments as departments for ease of management and for applying policies at the department-level. For LAN segments that are dynamically routed, you can assign only a data center department.

Alternatively, click Create Department to create a new department and assign the LAN segment to it. See Adding a Department.

DHCP

For directly connected LAN segments, click the toggle button to enable DHCP. DHCP is disabled by default.

You enable DHCP if you want to assign IP addresses by using a DHCP sever. You disable DHCP if you want to assign a static IP address to the LAN segment.

Note: If you enable DHCP, fields related to DHCP-related parameters appear and must be configured.

[DHCP-Related Fields]

IP Address Prefix

(for DHCP)

Enter the IP prefix of the DHCP IP address pool. For example: 192.0.2.10/24.

Address Range Low

Enter the starting IP address in the range of IP addresses that can be allocated by the DHCP server to the LAN segment.

Address Range High

Enter the ending IP address in the range of IP addresses that can be allocated by the DHCP server to the LAN segment.

Maximum Lease Time

Specify the maximum duration (in seconds) for which a client can request for and hold a lease on the DHCP server.

Range: 0 through 4,294,967,295 seconds.

Name Server

Specify one or more IPv4 addresses of the DNS server. To enter more than one DNS server address, type address, press Enter, and then type the next address, and so on. DNS servers are used to resolve hostnames into IP addresses.

Protocol

For dynamically routed LAN segments, select the routing protocol (BGP or OSPF) to be used by the data center department to learn routes from the data center.

BGP Configuration

 

Authentication

Select the BGP route authentication method to be used:

  • None—Indicates that no authentication should be used. This is the default.

  • Use MD5—Indicates that MD5 is to be used for authentication. If you choose this option, you must specify an authentication key.

Peer IP Address

Enter the IP address of the BGP neighbor.

Peer AS Number

Enter the autonomous system (AS) number BGP neighbor.

Auth Key

If you specified that MD5 should be used for authentication, specify an MD5 authentication key (password), which is used to verify the authenticity of BGP packets.

OSPF Configuration

 

OSPF Area ID

Specify the OSPF area identifier to be used for the dynamic route.

Authentication

Select the OSPF route authentication method to be used:

  • Password—Indicates that password-based authentication should be used. If you choose this option, you must specify the password. (This is the default).

  • Use MD5—Indicates that MD5 is to be used for authentication. If you choose this option, you must specify an authentication key.

  • None—Indicates that no authentication should be used.

Password

Enter the password to be used to verify the authenticity of OSPF packets.

MD5 Auth Key ID

If you specified that MD5 should be used for authentication, enter the OSPF MD5 authentication key ID.

Range: 1 through 255.

Auth Key

If you specified that MD5 should be used for authentication, enter an MD5 authentication key, which is used to verify the authenticity of OSPF packets.
