Title: OVER-DISK LACP LINK AGGREGATION METHOD AND DEVICE FOR PON ACCESS SYSTEM
Abstract:
Disclosed in the present invention are an over-disk LACP link aggregation method and device for a PON access system, relating to the field of link aggregation. The steps of said method are: a main control disk creating a link aggregation group, and adding the link aggregation group to a designated VLAN; the main control disk controlling aggregation group member ports on all line cards to interact LACP messages with a peer device; the main control disk determining all ports which have completed LACP message negotiation to be normal ports, and forming aggregation group table entries according to the port numbers of all the normal ports, the main control disk and all the line cards saving the aggregation group table entries; and when the operating states of the ports on the line cards change, the main control disk updating the aggregation group table entries according to port change information. In cases where the centralized architecture of the PON access system is not changed, the present invention can extend the uplink disk function of an Ethernet-type single disk, and increase the uplink link bandwidth, and thus significantly improve the reliability of the link.
