所以我只是在两个Cisco Catalyst交换机之间build立一个LACP。
片段的configuration如下:
[3550交换机 – 端口22和23连接到2950和24是路由器]
interface Port-channel1 switchport access vlan 50 switchport trunk encapsulation dot1q switchport mode trunk ! interface FastEthernet0/22 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode passive spanning-tree portfast ! interface FastEthernet0/23 switchport trunk encapsulation dot1q switchport mode trunk channel-group 1 mode passive spanning-tree portfast ! interface FastEthernet0/24 switchport access vlan 50 switchport trunk encapsulation dot1q switchport mode trunk switchport voice vlan 10 spanning-tree portfast ! interface GigabitEthernet0/1 switchport mode dynamic desirable ! interface GigabitEthernet0/2 switchport mode dynamic desirable ! interface Vlan1 no ip address ! interface Vlan50 ip address 10.10.10.12 255.255.255.0 ! ip default-gateway 10.10.10.5
[2950交换机 – 端口23和24连接到3550]
interface Port-channel1 switchport access vlan 50 switchport mode trunk flowcontrol send off ! interface FastEthernet0/23 switchport access vlan 50 switchport mode trunk channel-group 1 mode active spanning-tree portfast ! interface FastEthernet0/24 switchport mode trunk channel-group 1 mode active spanning-tree portfast ! interface Vlan1 no ip address no ip route-cache shutdown ! interface Vlan50 ip address 10.10.10.6 255.255.255.0 no ip route-cache ! ip default-gateway 10.10.10.5
现在我做了一些基本的“show inter trunk”和“show cdp neighbor”等来validation。 但是有没有更好的方法来确保这两个链路是聚合的,并增加了两个交换机之间的带宽? 我不知道这个“stream量控制”会不会打扰一下呢?
谢谢。
