Description
Technical field
The present invention relates to the field LACP, it is specifically related to a kind of realize LACP in the distributed apparatus for not supporting NSR
The method and system of NSR.
Background technique
LACP (Link Aggregation Control Protocol, link aggregation based on IEEE802.3ad standard
Control protocol) it is a kind of agreement for realizing link dynamic convergence.LACP agreement passes through LACPDU (Link Aggregation
Control Protocol Data Unit, link aggregate control protocol data cell) and opposite end interactive information.
The use occasion of LACP agreement:
It (1), can be by logical aggregate spread bandwidth to N times of former link in the case where bandwidth is more nervous.
(2) in the case where needing to carry out dynamic backup to link, it can be polymerize by configuration link and realize same polymerization
Dynamic backup each other between each member port of group.
The port for starting LACP can be there are two types of operating mode: Passive and Active.
Passive: Passive Mode, the mode lower port will not active transmission Link Aggregation Control Protocol Data Unit, receiving opposite end send
LACP message after, the port enter agreement calculate state.
Active: aggressive mode, the mode lower port actively can send Link Aggregation Control Protocol Data Unit to opposite end, carry out LACP agreement
It calculates.
After the LACP agreement for enabling certain port, which will notice the System Priority of oneself by transmission LACPDU to opposite end
Grade, system MAC Address, port priority, port numbers and Operational Key (key value).After opposite end receives these information, by these
The port that information can be converged compared with the information that other ports are saved with selection, so that both sides can be added or move back to port
Some dynamic convergence group is reached an agreement out.
Operational Key is in trunking, and LACP agreement is according to configuration (i.e. rate, duplex, basic configuration, the pipe of port
Manage Key) generate a configuration combine.
After enabling LACP agreement, management Key defaults to zero for dynamic convergence port.Static state convergence port is enabling LACP
Afterwards, the management Key of port is identical as convergence group ID.
For dynamic convergence group, centainly there is identical Operational Key with group membership, and by hand and in static convergence group,
Port Operational Key having the same in Active.
Trunking is that multiple trunkings are formed to a convergence group together, to realize in/out load in convergence group
In sharing in each member port, while also providing higher connection reliability.
NSR (Non-Stop Routing, routing free of discontinuities) be in the equipment for having main control board and slave control board,
A kind of reliability engineering of neighborhood is not influenced when main control board breaks down, by agreement back mechanism, realizes master
It is not interrupted for control plane (routing) and Forwarding plane (business) when switching.Realize that the cost of NSR function is very high, NSR is to whole
A equipment it is more demanding, general distributed apparatus does not support NSR function, in the distributed apparatus for not supporting NSR function,
LACP can not generally also support the NSR function of LACP.
Summary of the invention
The purpose of the invention is to overcome the shortcomings of above-mentioned background technique, provide a kind of in the distribution for not supporting NSR
