S5700 eth-trunk Port aggregation and trunk removal

eth-trunk Port aggregation for S5700

Link aggregation and port aggregation are port aggregations, and the stack of switches is not related to stacking and port aggregation.

Port Aggregation Concepts: (includes two layer port aggregation and three layer port aggregation)

1. Port aggregation IEEE standards are a link that aggregates up to 16 links into a single logical path. Only 8 of them can be used,

The remaining 8 articles are used as backups.

2. Do the aggregation of port configuration, physical media properties (duplex mode, interface bandwidth, etc.) must be the same

3. Port aggregation can increase bandwidth, but is not a physical improvement, but is based on increased load balancing

4. Port aggregation port can only be 2 times the number of links to do the aggregation, that is, only 2, 4, 6, 8 links do aggregation,

Cannot be an odd link to do aggregation

Eth-trunk Simple Port aggregation: (Local load Balancing)

SW1:

[Sw1]interface eth-trunk 1 #建立汇聚端口1

[Sw1-eth-trunk1]port link-type Access #更改端口为访问端口, if the following are two switches, you need to change to port Link-type trunk mode.

[Sw1-eth-trunk1]mode manual Load-balance #添加手动本地负载模式

[Sw1-eth-trunk1]quit

If the Gigabitethernet 0/0/1 interface is disconnected under the condition of the capture packet verification, it will automatically switch to the Gigabitethernet 0/0/2 port for communication.

the correct way to remove the trunk from the port:

(Because the port is in Vlan1 by default, if all is removed, the port has no default vlan1 configuration and needs to be added back in order to continue the next removal.) )

These three computers are used for testing, in fact, directly in exchange for Ping can also be tested, purely personal habits.

The detection can be ping-pass, and the clutch can be automatically switched.

Note: When configuring Eth-trunk locally, the Eth-trunk configuration is also performed on the peer, and routing can be used to achieve interoperability between different network segments.
