请教各位大牛,以下是问题详细描述,
一、在两个交换机上都配置了trunk、位于两个交换机上的两个vlan能够ping通
// 配置trunk
sw1(config)#interface gigabitethernet 0/25
sw1(config-if-gigabitethernet0/25)#switchport mode trunk
sw1(config-if-gigabitethernet0/25)#switchport trunk allowed vlan all
sw1(config-if-gigabitethernet0/25)#switchport trunk pvid vlan 1 //默认vlan
sw1(config-if-gigabitethernet0/25)#exit
sw1(config)#
二、将0/25~0/27配置为链路聚合后,两个交换机上的两个vlan就ping不通了
// 多接口link-aggregation
sw1(config)#link-aggregation 1 mode manual //group ID = 1
sw1(config)#interface gigabitethernet 0/25-0/27
sw1(config-if-range)#link-aggregation 1 manual
sw1(config-if-range)#no shutdown
sw1(config-if-range)#exit
sw1(config)#
三、问题分析:链路聚合是up、没看出有什么问题
