pushed out to each branch switch when it comes up on the network. If a branch switch is removed from the
master, the IP addresses allocated to that branch switch can be reused and reassigned to a new branch switch.
A master switch must have a separate VLAN pool defined for each VLAN used by its branch switch. A VLAN pool
allocates a static, continuous block of multiple IP addresses to each branch switch. The branch switch acts as a
DNS proxy server and dynamically assign IP addresses from its allocated pool to each AP or client on the VLAN.
The tunnel pool on a branch switch defines a range of IP addresses that the branch switch uses to create a GRE
tunnel within the IPsec tunnel back to the master switch. Unlike VLAN pools, which allocates multiple addresses
to each branch switch VLAN, the tunnel DHCP pool assigns a single tunnel IP address to each branch switch.
Static vs Dynamic IPManagement
If you choose the dynamic IP management option, you must define one or more IP address pools with a range
of sharable addresses. The master switch then divides each IP address pool into unique subnets that can
support the required number of clients per branch, and assigns one of these subnet to each branch switch.
If a branch deployment has existing IP addressing that needs to be preserved (for example, the printers at a
branch office have static IP addresses), then the branch config group should use static IP addressing. When
you create a branch config group that uses static IP addressing, you must export the AOS-W static IP
addressing template from the master switch, define the IP settings for the devices that need a static IP address
within that template, then import the template file back into a branch config group.
Starting from AOS-W 6.5, the ZTP feature is enhanced to support 16 VLANs per branch switch as against just
four in the earlier versions of AOS-W. Except this VLAN enhancement, all the other configurations for the ZTP
feature remain the same as in previous AOS-W versions.
The Bulk Edit template (in Excel sheet) on the branch switch allows you to specify the static IP assignment for
individual branch switch devices. The static IP configuration is maintained in this Bulk Edit CSV file, with each
line in the file representing the settings for a specific branch switch device. To support this enhancement, the
Bulk Edit Excel sheet (.CSV format) is now expanded to allow for addition of up to 16 VLANs for each branch
switch.
The DHCP pools for the VLANs will have settings for the following parameters: pool name, domain name,
domain name server, VLAN ID, IP address, mask, and the IP address exclude list.
To create a new branch config group:
1. Navigate to Configuration > Branch > Smart Config and select the Management tab.
2. Click the New button under the branch config group list. You are prompted to enter a name for the new
branch config group profile.
3. Click OK.
4. Next, click the Model drop-down list and select the model type of your branch switches. Each profile can
support a single switchmodel .
5. Click the IP Address Management drop-down list and select the Static or Dynamic option.
6. If you select Dynamic, each branch office switch will get an IP address using DHCP.
7. If you select Static, the WebUI gives you the option to select export and download the static IP address
template export-RemoteNode.csv, or select import and upload a completed static IP address .csv file.
8. Click Apply to save your settings.
The export-RemoteNode.csv template defines the following settings for each branch switch in the branch
config group. Complete the template by adding information for up to 16 IP address pools for each branch
switch.
