Juniper ACX2000 Configuration Guide

NOTE: The maximum number of DHCP (and DHCPv6) local server clients
or DHCP (and DHCPv6) relay clients can also be specified by Juniper Networks
VSA 26-143 during client login. The VSA-specified value always takes
precedence if the interface-client-limit statement specifies a different number.
If the VSA-specified value differs with each client login, DHCP uses the largest
limit set by the VSA until there are no clients on the interface.
To configure the maximum number of DHCP clients allowed per interface:
1. Specify that you want to configure override options.
•
For DHCP local server:
[edit system services dhcp-local-server]
user@host# edit overrides
•
For DHCPv6 local server:
[edit system services dhcp-local-server dhcpv6]
user@host# edit overrides
•
For DHCP relay agent:
[edit forwarding-options dhcp-relay]
user@host# edit overrides
•
For DHCPv6 relay agent:
[edit forwarding-options dhcp-relay dhcpv6]
user@host# edit overrides
2. Configure the maximum number of clients allowed per interface. (DHCP local server,
DHCPv6 local server, DHCP relay agent and DHCPv6 relay agent all support the
interface-client-limit statement.)
[edit system services dhcp-local-server overrides]
user@host# set interface-client-limit number
NOTE: For DHCP local server and DHCP relay agent, you can use either the
interface-client-limit statement or the client-discover-match incoming-interface
statement to set a limit of one client per interface. The interface-client-limit
statement with a value of 1 retains the existing client and rejects any new
client connections. The client-discover-match incoming-interface statement
deletes the existing client and allows a new client to connect.
