not allow the administrators to assign

the remaining IP addresses to another

branch, although a lower value is

configured for the client count.

router for the Distributed, L2 DHCP

dhcp-relay

Enables the W-IAPs to intercept the

broadcast packets and relay DHCP

requests directly to corporate network.

The DHCP relay is enabled for the

centralized DHCP scopes to reduce

network traffic caused by the

broadcasting of DHCP requests to the

corporate network. With a centralized

DHCP scope, the clients in the branch

are in the same subnet as clients in the

corporate network. Normally the DHCP

request goes through the VPN tunnel

and is broadcast into the corporate

network. This feature allows it to

succeed without requiring to broadcast

and thus reduces the network traffic.

— —

dhcp-server <dhcp_

server>

Defines the IP address of the corporate

DHCP server for DHCP request relay.

— —

disable-split-

tunnel

Disables split tunnel functionality for

Centralized L2 subnets.

Split tunneling allows a VPN user to

access a public network and a local

LAN or WAN network at the same time

through the same physical network

connection.

When split-tunnel is disabled, all the

traffic including the corporate and

Internet traffic is tunneled irrespective of

the routing profile specifications. If the

GRE tunnel is down and when the

corporate network is not reachable, the

client traffic is dropped.
