dhcpv6 relay access-limit

Function

The dhcpv6 relay access-limit command configures the maximum number of access DHCPv6 clients on a DHCPv6 relay interface.

The undo dhcpv6 relay access-limit command deletes the maximum number of access DHCPv6 clients on a DHCPv6 relay interface.

By default, the maximum number of access DHCPv6 clients is not limited on DHCPv6 relay interfaces. Only the maximum number of DHCPv6 clients on the entire device is limited.

Usage Guidelines

Usage Scenario

To limit the maximum number of access DHCPv6 clients during network planning or service adjustment, run the dhcpv6 relay access-limit command.

The dhcpv6 relay access-limit limit-number command configures the maximum number of access DHCPv6 clients on a DHCPv6 relay interface.

Configuration Impact

This command takes effect for subsequent DHCPv6 clients that go online. The maximum number of online DHCPv6 clients is not limited.

Precautions

If the dhcpv6 relay access-limit command is run with a VLAN range specified, and then the undo dhcpv6 relay access-limit command is run with a smaller VLAN range specified, the first VLAN range is divided into two parts. After the VLAN range specified in the dhcpv6 relay access-limit command is divided into 16 parts, the undo dhcpv6 relay access-limit command can no longer be run.

Example

# Configure GE 0/1/0 to allow a maximum of 100 DHCPv6 clients to go online.
