In order to allow those skilled in the art better understand content of the present invention, below in conjunction with accompanying drawing and concrete
Embodiment is further detailed content of the present invention:
Fig. 1 is the basic logic framework of ethernet communication system, as shown, interconnect by the panel switching network between Main subrack switching network veneer and the non-central frame switching network veneer, other veneers in Main subrack switching network veneer and the frame are connected by backboard, between the switching network of non-central frame and the switching network of Main subrack by the interconnection of panel network interface.Non-central switching network veneer links to each other by backboard with other interior veneers of its frame.A port interconnection is also arranged between the CPU of each switching network and the switching network veneer, and Backend Administration Module (Back AdministrationModule is called for short BAM) is connected with BAM by the 0th networking mouth.
What deserves to be explained is that switching network veneer as herein described is the switching control unit (Switch Control Unit is called for short SCU) that has the service management controlled function in the Ethernet.
The BOOTP of each veneer in the system when starting asks to obtain MAC Address and IP address separately.BOOT strapping Protocol (BOOTP) is a kind of agreement based on User Data Protocol (User Data Protocol is called for short UDP)/IP.This agreement allows the main frame dynamic-configuration that is starting and need not user's supervision.The BOOTP agreement has two kinds of messages, is respectively: BOOTP request and BOOTP response.Each territory of BOOTP message is fixed-length field, and two kinds of message formats are identical.
In the BOOTP message definition hardware address (MAC Address) is arranged, get fixed value for high 32 of 48 bit mac addresses of communication equipment, back 16 structure as shown in Table 1:
Table one:
| Frame Frame (5bits) | Groove Slot (5bits) | Active and standby/non-active and standby sign Flag (1bits) | Port numbers Port (5bits) |
By table one as seen, the MAC Address territory is divided into four parts: frame number, groove number, active and standby/non-active and standby sign and port numbers.
For groove number,, therefore can fill in groove number automatically by veneer itself because veneer can read the groove number at place own; For active and standby/non-active and standby sign, same veneer self can clearly know whether adopt active/standby mode according to being provided with, and active and standby/non-active and standby sign is carried out value, such as: if adopt active/standby mode, then flag is got 0, otherwise flag gets 1; For port numbers, same, veneer self can know and obtain therefore can also have veneer self to fill in; For frame number, if under the situation of frame dial-up, can obtain, and if under the situation that does not have the frame dial-up, this part can all extend this as default frame number by the frame dial-up.
Below by being example with the different veneers in the communications network system, the inventive method is specifically described.
Communications network system as shown in Figure 1, at first default all network interface transmissions of message that send by BAM on BAM by being connected with Main subrack SCU, promptly all are by VLAN ID (the Virtual LAN ID of the message of BAM transmission, be called for short VLAN ID) be the VLAN ID of this network interface, in this embodiment, the VLAN ID that establishes this network interface is 1.According to above-mentioned setting, promptly all are sent to Main subrack SCU by the message that BAM sends, and are transmitted or other processing by Main subrack SCU.
For make can by BOOTP can obtaining communication equipment MAC Address, so in the BOOTP message, define the hardware address territory, in the hardware address territory, comprise the frame territory: the first frame territory.
By network architecture shown in Figure 1 as can be known, the startup of each communication equipment must be adopted from top to bottom
Boot sequence promptly at first starts with the direct-connected Main subrack SCU of BAM, restarts and Main subrack SCU
Joining service board and the next stage SCU that is connected with Main subrack SCU, by that analogy.
Embodiment 1:
Present embodiment is to be that example is specifically described the inventive method with the direct-connected Main subrack SCU of BAM in the communications network system, and Fig. 2 is the method flow schematic diagram of present embodiment, and as shown, this method may further comprise the steps:
Step S201: Main subrack SCU starts.
Start Main subrack SCU, only open the 0th networking mouth of panel, it is VLANID=1 that this network interface belongs to default network interface, and on Main subrack SCU, be provided with from the institute that the 0th networking mouth enters and have or not VLAN ID (VLAN TAG, being called for short TAG) message or TAG equal 0 message and add a specific VLANID, to indicate this message from higher level's communication equipment (for Main subrack SCU, this higher level's communication equipment is BAM at this), establishing this specific VLAN ID is 1000.
Step S202: Main subrack SCU sends the BOOTP message to BAM.
Main subrack SCU sends no TAG or TAG to BAM in the mode of broadcasting and equals 0 BOOTP and ask, and the first frame territory in the BOOTP message is extended this as default value, and this default value can be preset, and in this embodiment, getting this default value is 0 for convenience of explanation.
According to the setting among the step S201, owing to only open the 0th networking mouth, so this BOOTP message is sent to direct with it joining BAM behind the 0th networking mouth.
Step S203:BAM receives the BOOTP message, and fills in frame number and IP address in the BOOTP message.
After BAM receives this BOOTP message from the 0th networking mouth, provide the BOOTP response, extend this as the IP address of this BOOTP configuration in the IP address field in the BOOTP message of response.And the value according to the first frame territory in the hardware address territory in the BOOTP message is a default value, know that this message is directly from Main subrack SCU, provide its BOOTP response, and, according to the MAC Address configuration that is provided with in the BAM, the actual frames of this Main subrack SCU correspondence number is inserted in the first frame territory in the BOOTP response, replaced former frame number.
Step S204:BAM returns the BOOTP message to Main subrack SCU.
BAM is sent to Main subrack SCU with this BOOTP response, the VLAN ID=1 of this BOOTP response in the mode of broadcasting.
Step S205: Main subrack SCU receives the BOOTP message, and obtains MAC Address and IP address according to the BOOTP message.
Main subrack SCU receives this BOOTP response from the 0th networking mouth, because this message during through the 0th networking mouth, is added VLAN ID=1000, so Main subrack SCU receives this BOOTP message, and transfers to CPU and handle.
Main subrack SCU resolves this BOOTP message, the frame in the first frame territory in the message number is filled up in the frame number of the MAC Address on this equipment, add the port numbers that directly can read at this communication equipment end, groove number and active and standby/non-active and standby sign value, so far this communication equipment is finished the MAC Address configuration of this equipment.
Simultaneously, this communication equipment responds according to BOOTP, gets access to IP address and other corresponding BOOTP information.
Step S206: carry out follow-up software loading and startup.
Main subrack SCU carries out follow-up software loading and startup, after software loading and startup are finished, all distributes a VLAN ID who is used to replace the VLAN ID of non-TAG bag or TAG=0 bag for the port of the panel of Main subrack SCU.For example: for example port set 0～5 is respectively 1000～1005, and these ports are supported vlans=1 simultaneously; The all of the port branch of backboard is used in the VLAN ID of the VLAN ID that replaces non-TAG bag or TAG=0 bag, for example can be taken as 970～997, simultaneously all backboard ports supported vlans=1 all; The cpu port of SCU is then supported all these VLAN ID (1,970～997,1000～1005), i.e. the CPU of Main subrack SCU reception and processing VLAN ID are 1,970 to 997 and 1000 to 1005 bag.
So far, Main subrack SCU gets access to MAC Address, IP address and other BOOTP information, communication device initiated finishing by the BOOTP message automatically by the BAM configuration.
But,, can continue to carry out following steps in order to make Main subrack SCU have the function of proxy configurations MAC Address.
Step S207:BAM issues the frame allocation list to Main subrack SCU.
BAM issues the frame allocation list by ground 0 networking mouth to Main subrack SCU, and in the frame allocation list, the VLAN ID that makes this communication equipment port is number corresponding one by one with each frame respectively.
Step S208: Main subrack SCU obtains the frame allocation list.
In the present embodiment, be primarily aimed at the mode of non-employing hardware dial-up, the situation that disposes MAC Address by network automatically is illustrated, in order to make the inventive method be equally applicable to the mode that the hardware dial-up writes.Can also in the BOOTP message, increase another frame territory: the second frame territory, be used to fill in the frame number of user's dial-up input, promptly in step S201, in this dial-up frame territory, fill in frame that Main subrack SCU reads number, if Main subrack SCU can not read frame number, promptly do not adopt user's dial-up writing mode, then each bit in this second frame territory is filled out one writing entirely; When Main subrack SCU receives the BOOTP message that BAM returns, can compare the value in the first frame territory and the second frame territory, judge whether the MAC Address of user's dial-up is the same with the MAC Address of distributing automatically.When circuit trouble shoot or other equipment fault eliminating, be convenient to get rid of because the fault that the hardware dial-up is dialed the wrong number and caused.
