(Optional) Configuring an IP Address Pool for a Sub-VLAN

(Optional) Configuring an IP Address Pool for a Sub-VLAN

Specifying an IP address range for users in a sub-VLAN filters out unauthorized users of which IP addresses are beyond the range.

Context

Specifying an IP address range for users in a sub-VLAN filters out unauthorized users of which IP addresses are beyond the range.

After configuring an IP address pool for a sub-VLAN, note the following points:
  • Only packets with IP addresses in the IP address pool are processed in the sub-VLAN. The packets include ARP Request packets, ARP Reply packets, and ARP proxy packets. Packets with IP addresses beyond the IP address pool are discarded.
    NOTE:
    If the sub-VLAN and DHCP address pools are used together, ensure that the range of the sub-VLAN address pool covers the range of the DHCP address pool. Or, do not use the sub-VLAN and DHCP address pools together.
  • Only entries mapping IP addresses in the IP address pool are learned in the sub-VLAN.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The view of a created sub-VLAN is displayed.

  3. Run ip pool start-address [ to end-address ]

    An IP address pool is configured for the sub-VLAN.

  4. Run commit

    The configuration is committed.
