思科模拟器 交换机链路聚合(二层、三层)

端口聚合工作原理 将连接多个物理链路的端口捆绑在一起形成一个逻辑端口,这个逻辑端口成为聚合端口(AP)。聚合端口AP的功能遵循IEEE802.3ad标准,目标是扩展链路带宽,提高链路可靠性。 端口聚合条件: 一般交换机最多支持8个物理端口组成一个聚合端口,同时要满足以下条件: 1、物理端口速度相同; 2、物理端口介质相同; 3、物理端口层次一致; 4、AP成员端口必须属于同一个VLAN。

端口聚合又称链路捆绑,分为二层端口聚合和三层端口聚合。二层端口聚合针对二层交换机,交换机接口只能是二层性质的,接口链路类型可以设置为trunk和access,形成的链路不带IP地址功能。三层聚合端口也称为路由聚合端口,针对三层交换机,形成的链路带IP地址功能,则不能设置链路类型为trunk和access。原文链接:https://blog.csdn.net/STARDEIT/article/details/119833428

二层聚合端口配置 配置二层聚合端口的过程: 1、创建聚合端口 2、将端口绑定到聚合端口 3、设置聚合端口类型

下面是以思科模拟器为例做二层聚合端口操作步骤: 1、创建聚合组进入聚合接口模式(全局模式) Switch(config)#interface port-channel 1 2、将端口绑定到聚合端口(接口模式) Switch(config)#int range f0/1-3 Switch(config-if-range)#channel-group 1 mode on channel-group指定当前端口要加入到的聚合组(聚合端口ID) 3、聚合接口下端口配置(聚合接口模式) Switch(config)#int port-channel 1 Switch(config-if)#switchport mode trunk

三层聚合端口配置 配置三层聚合端口的过程: 1、创建聚合端口,并将类型设置为三层端口(路由端口),并为其配置IP地址。 2、将需要加入的物理端口类型设置为三层端口。 3、将需要加入的物理端口加入到聚合端口。 4、如有不同网段的信息通信,需要开启路由,并做路由配置。

下面是以思科模拟器为例做二层聚合端口操作步骤: 1、创建聚合组进入聚合接口模式(全局模式) Switch(config)#interface port-channel 1 2、将端口绑定到聚合端口(接口模式) Switch(config)#int range f0/1-3 Switch(config-if-range)#channel-group 1 mode on channel-group指定当前端口要加入到的聚合组(聚合端口ID) 3、聚合接口下端口配置(聚合接口模式) Switch(config)#int port-channel 1 Switch(config-if)#switchport mode trunk 4、全局模式下开启路由功能 Switch(config)#ip routing Switch(config)#ip route 192.168.1.0 255.255.255.0 192.168.12.1
