(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.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.
