Default
ip-range <start_IP>
<end_IP>
Defines a range of IP addresses to use in
the distributed, L2 and distributed, L3 DHCP
scopes. You can configure a range of DHCP
IP addresses used in the branches and the
number of client addresses allowed per
branch. You can also specify the IP ad-
dresses that must be excluded from those
assigned to clients, so that they are as-
signed statically. You can configure up to
four different ranges of IP addresses
• For
Distributed, L2
mode, ensure that all
IP ranges are in the same subnet as the
default router. On specifying the IP ad-
dress ranges, a subnet validation is per-
formed to ensure that the specified
ranges of IP address are in the same
subnet as the default router and subnet
mask. The configured IP range is divided
into blocks based on the configured
client count.
• For

mode, you can con-
figure any discontiguou s IP ranges. The
configured IP range is divided into
multiple IP subnets that are sufficient to
accommodat e the configured client
count.
