This series includes: STP, RSTP, MSTP, VLAN, LACP, Super VLAN. To study the experimental setup as the main objective;
Link Aggregation Control Protocol-- LACP
utilized in a broadband tense situation, bind two or more ports together as a logical port to enhance the high-bandwidth link speed, redundancy and load balancing.
The protocol has the following characteristic analysis: compatibility, load balancing, redundancy link; aggregation ends respectively Actor and Partner.
LACPDU include: system priority, system MAC, port priority, port number, and operational key; compare this information to select the port can converge, so the two sides can join or leave a port dynamic aggregation agreement.
Aggregation way different: manual, static and dynamic.
An aggregation group port (STP, QoS, VLAN, port attributes, etc.) must be the same.
Key operation when a port aggregation, the system according to the port (speed, duplex, basic configuration, management key) is configured to a configuration combinations.
静态链路汇聚：
interface eth-trunk6
trunkport g0/0/6 to 0/0/7
#接口型号注意
port link-type trunk
port trunk allow-pass vlan 1 12 34
#允许vlan通过
load-balance src-dst-ip
lacp priority 100 (LACP主动链路端)
Display eth-trunk!
Super VLAN 即 VLAN Aggregation
Super VLAN (Configuration Layer Interface ) comprises a plurality of sub VLAN (broadcast domain Layer isolated from each other )
when the user communications within the three sub VLAN, Super VLAN IP address is used as Layer 3 interface gateway address, so that a plurality of a common sub VLAN IP network segment, the same routing interfaces to save IP address resources . Which proxy ARP implements communication between the three-story isolation port.
The switch supports VLAN aggregation , Super VLAN no member ports.
Super VLAN 配置命令总结：
vlan 10
aggregate-vlan
access-vlan 2 to 3
interface Vlanif 10
