(Optional) Configuring PPP User Access Limitations

(Optional) Configuring PPP User Access Limitations

To prevent unauthorized users from initiating a brute force attack to crack the password of an authorized user or the number of access users, configure the maximum number of users allowed to go online through a board or MAC address.

Context

On live networks, unauthorized users may use a brute force attack to crack the password of an authorized user or the number of access users. To prevent this problem, configure the maximum number of users allowed to go online through a board.

Multiple users may use the same MAC address for network access. To allow PPPoE users to use the same MAC address to go online through the same device, configure the maximum number of users allowed to go online through a MAC address.

When PPPoE users are online, a downstream device failure will cause the NE40E to receive a large number of NCP negotiation requests from some users, resulting in high CPU usage. Therefore, the number of NCP negotiation times must be limited.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run pppoe-server slot-number max-sessions session-number

    The maximum number of users allowed to go online through a board is configured.

  3. Run pppoe-server max-sessions remote-mac session-number

    The maximum number of users allowed to go online through a MAC address is configured.

  4. Run pppoe-server negotiation times limit

    The number of NCP negotiation times is limited.

  5. Run commit

    The configuration is committed.
