Parameter Description
IP Address Range IP addresses at the start and end of the branch switch’s address range, in dotted-
decimal format and the netmask per branch. The WebUI converts the netmask per
branch to hosts count.
Example: If the netmask per branch is /27, WebUI calculates the hosts count as 32.
Similarly, if netmask per branch is /24, the WebUI calculates the hosts count as 256.
Lease Lease time for addresses in the DHCP pool. If unconfigured, the default value is 12
hours.
Option Use this field assign the client to a VLAN based upon the DHCP signature ID.
Next-Hop Device lists
If the switch uses policy-based routing to forward packets to a next hop device, a next-hop list ensures that if
the primary next-hop device becomes unreachable, the packets matching the policy can still reach their
destination. For more information on nexthop devices, see Routing Configuration on page 242.
To define a next-hop list:
1. Navigate to Configuration>Branch>Smart Config>Routing and select the PBR sub-tab.
2. Click the Add button below the Nexthop Configuration table to open a pop-up window that allows you
to configure the following next-hop settings:
Parameter Description
Nexthop-list name Name for the new nexthop list.
Nexthop IP / DHCP IP address of the nexthop device or the VLAN ID of the VLAN used by the nexthop
device. If the VLAN gets an IP address using DHCP, and the default gateway is
determined by the VLAN interface, the gateway IP is used as the nexthop IP address.
When you click Add to define a NextHop IP or DHCP value, a pop-up list appears and
field requires you to select either the IPor DHCP option.
n IP: In the Nexthop Value and Priority fields, enter the IP address and priority of
the nexthop device
n DHCP: In the Nexthop Value and Priority fields select the VLAN and priority of
the nexthop device.
Preemptive-Failover If preemptive failover is disabled and the highest-priority device on the nexthop list
is disabled, the new primary nexthop device remains the primary even when the ori-
ginal device comes back online.

PBR Rules
A policy-based routing (PBR) rule is an ACL that can forward traffic as normal, or route traffic over a VPNtunnel
specified by an IPsec map, routed to a nexthop router on a nexthop list, or redirected over an L3 GRE tunnel or
tunnel group.
