The Port Bind Configuration of bind(distributing-mode)

Function

This command is used to bind an IP address to a service port. To specify a permitted IP address for a service port, run this command. After the IP address is successfully bound to a service port, the device allows only upstream packets whose source IP address is the bound IP address to pass.
The undo bind command is used to unbind an IP address from a service port. After the IP address is unbound from the service port, the device does not filter upstream packets by source IP address.

Usage Guidelines

  • After an IP address is bound to a service port, the service forwarding module checks the source IP address of the packet sent from the user. If the source IP address (only the IPv6 prefix is matched for IPv6 packets and IPv6 addresses) of a user-side packet differs from all IP addresses that are bound to the receiving service port, the packet is discarded.
  • The IPv4 address bound to a service port must be a unicast IP address. An IPv4 address can be bound to a network segment with the length ranging from 17 bits to 32 bits or can be bound to an IPv4 address.
  • The IPv6 address bound to a service port must be a unicast IP address. An IPv6 address prefix with the length of 48 bits, 56 bits, 60 bits, or 64 bits, or an IPv6 address can be bound to a port. The IPv6 prefix bound to a port cannot have a length longer than 64 bytes.
  • The number of IP addresses that can be bound to a service port is limited. Each service port can be bound to a maximum of eight IPv4 addresses, four IPv4 address network segments, four IPv6 prefixes, or two IPv6 addresses. IPv4 and IPv6 share the hybrid service ports (resources) that support both IPv4 and IPv6 services. The resources occupied by each IPv6 prefix are twice that of an IPv4 address; the resources occupied by each IPv6 address are four times of that of an IPv4 address; the resources occupied by each IPv4 network segment are the same as that of an IPv4 address. Addresses can be bound only when the corresponding resources are available.
  • To ensure that DAD packets are transparently transmitted, bind a maximum of six static IPv4 addresses to a service port (one dynamic IPv6 address occupies resources of two static IPv4 addresses).
  • If a service port belongs to a bundle, the bound IP address takes effect to the entire bundle. All service ports in a bundle can be bound to a maximum of eight IPv4 addresses, four IPv4 network segments, four IPv6 prefixes, or two IPv6 addresses. For the bundle that contains hybrid service ports, the resources occupied by each IPv6 address are twice that of an IPv4 address. Addresses can be bound only when the corresponding resources are available.
  • Only H805GPBD supports IPv4 network segment binding. When bound to other boards, an IPv4 network segment is bound to the boards as multiple IPv4 addresses.
