Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
Usually, switch power on or port UP (relieving) time, its port enters study (1earning) state.Port under learning state can learning MAC address, but does not E-Packet.After certain hour length (as 30 seconds), port moves to forwarding (forward) state by learning state, and the port under forwarding state can E-Packet.
In the embodiment of the present invention, the MAC address learning process of above-mentioned switch is improved, that is, when the MAC Address having two or more port to learn is identical, these study are arrived the port trunking of identical MAC Address together, forms aggregation group.
Concrete, as shown in Figure 3, when switch power on or port UP time (step 301), corresponding port enters learning state and carries out MAC address learning (if switch powers on, other port realizing message repeating for interconnection network equipment then except stack port enters learning state, if port UP, this port enters learning state, sees step 302); Whether the two or more ports judging to be in learning state acquire same MAC Address (step 303), if, then switch configuration aggregation group, and these study are added this aggregation group (step 304) to the port of same MAC Address as member port, after this, after setting is long-time, the migration of this aggregation port is forwarding state; Otherwise carry out MAC address learning in a conventional manner, after setting is long-time, the port migration being in learning state is forwarding state.Fig. 4 shows the schematic diagram after port trunking, and wherein, because port P11 with P12 of switch is connected with the different port of EC respectively, therefore study is to the MAC Address of this EC, and then port P11 and P12 condenses together.
In above-mentioned flow process, preferably, switch is configurable parameter from entering learning state to the time span that migration is forwarding state.(as less in network size or network performance better, then configurable shorter time span, as being less than or equal to 30 seconds can to configure suitable time span according to the network environment such as network size, network performance; Otherwise, network size is comparatively large or network performance is poor, then configurable longer time span, as being greater than 30 seconds), thus can ensure that switch ports themselves can learn the MAC Address of other equipment in this period on the one hand, this time span can be shortened again as far as possible, enter forwarding state as early as possible to process message to make switch ports themselves.
When through after a while, after the port of learning state moves to forwarding state, as shown in Figure 5, when there being message to arrive certain member port of aggregation group (step 501), switch checks whether the source MAC of this message learnt at other port (other port herein does not comprise the member port of this aggregation group), that is, whether the source MAC of this message is present in (step 502) in the mac address table of other port; If other port had learnt this MAC Address, then show that this aggregation group member port is not the port that starts connecting this MAC Address equipment (namely MAC Address is the equipment of the source MAC of this message), now, the aggregation group member port receiving this message abandons this message received, and do not learn the source MAC of this message on that port, in order to avoid flow is caused to spread unchecked the problems (step 503) such as obstructed with follow-up forwarding; If other port did not learn this MAC Address, then show that this port is the port that starts connecting this MAC Address equipment, now, the port receiving this message conveniently flow process forwards this message, namely, mac address table according to this port configures matches port, and forwards this message (step 504) by the outbound port matched.
Below in conjunction with the group-network construction shown in Fig. 2 and concrete scene, the implementation procedure of the embodiment of the present invention is described in detail.
After broadcasting packet enters switch from port P10, port P10 learns the MAC Address of this broadcasting packet, switch forwards to all of the port, naturally also forwards from aggregation port (member port of this aggregation port comprises P11 and P12), supposes to go out from P11 port repeat.EC receives this broadcasting packet from P1 port, because the exchange chip of EC does not support polymerization property, so EC is also to its all port repeat, sends comprising from port P2.Now, exchange opportunity receives from the another one member port P12 aggregation port the broadcasting packet just forwarded, but other ports (i.e. P10) study of the source MAC of this broadcasting packet in mac address table has in a switch been arrived, so port P12 abandons this message, thus no longer broadcast this message.
By describing above and can finding out, in the embodiment of the present invention, because two network interfaces of EC are on same exchange chip, therefore there is identical MAC Address, when the switch be connected with two network interfaces of this EC powers on, the port of switch enters learning state, is in learning state and will learns identical MAC Address with 2 switch ports themselves that two network interfaces of EC connect respectively, these 2 ports are added aggregation group by such switch, form aggregation port.When there being message to enter aggregation port (or certain member port of aggregation port) of switch, by judging whether the source MAC of this message learnt at other port of this switch, thus can judge whether this inbound port is the port that starts connecting this MAC Address equipment, if this inbound port is not the port that starts connecting this MAC Address equipment, then abandon this message, in order to avoid cause flow to spread unchecked, if this inbound port is the port that starts connecting this MAC Address equipment, then conveniently flow process forwards this message, to ensure that business is normally carried out.
