LAN | DHCP Pools

These settings are mergeable. However, the following actions require a merge with service disruption.

• Changing the Start Address, Subnet Mask or Default Router value for an existing DHCP Pool of addresses.

• Decreasing Pool Size for an existing DHCP Pool of addresses.

• Deleting an existing DHCP Pool of addresses.

When these actions are performed, the DHCP (Server or Dial In) is re-initialized which triggers a reboot of the Avaya DHCP Clients (H.323 and SIP) to force those clients to renew their IP address leases and apply the new settings. For the remaining Avaya and non-Avaya DHCP clients, you must manually reboot the devices to force an IP Addresses lease renewal. Otherwise, the devices continue to use their existing IP addresses until the IP addresses lease expires. IP address lease time out is set to three days.
