Impact

If DHCPv4 and PPPoEv4 users with the same MAC address go online from a remote address pool at the same time, the DHCP server may incorrectly distribute response packets to users, causing user login failures.

Deploy a local address pool and a remote address pool or two local address pools for DHCP and PPPoE users with the same MAC address.

If a PPPoEv4 user requests to go online when a DHCPv4 user is waiting for a response from the DHCPv4 server, the server may send the response for the DHCPv4 user to the PPPoEv4 user. As a result, both users fail to go online.

If a DHCPv4 user requests to go online when a PPPoEv4 user is waiting for a response from the DHCPv4 server, the server may send the response for the PPPoEv4 user to the DHCPv4 user. As a result, both users fail to go online.

If the first user has successfully gone online and the remote server can distinguish between the DHCPv4 user and the PPPoE user during address allocation, the second user can go online successfully.

In an upgrade scenario where RUI inter-chassis borrowing is configured, the device with a RUI-slave address pool deployed runs a new version, whereas the device with a local address pool deployed runs an old version. When a PPPoEv4 user requests to go online or renew the lease from the device with a RUI-slave address pool deployed, the device fails to identify the user for whom the NAK message is intended. If the NAK message indicates that there is no available address in the local address pool, a failure in identifying the receiver of the NAK message will reduce the login success rate.

If a DHCPv4 or PPPoEV4 user with the same MAC address as the preceding PPPoEv4 user requests to go online or renew the lease from a remote address pool, the two types of users may fail to go online or renew the lease.
