一、注意点一
Z9000和4810类似,都需要在做任何操作前敲上reload-type normal-reload,防止操作不生效。
二、Z9000将40G接口分割成4x10G接口
命令:Stack-unit 0 port X portmode quad 【x表示哪个接口】
(一)Qsfp是40g口,sfp+就是10g,sfp就是千兆也就是1g口。
(二)接口分割后需要重启才会生效,需要恢复40G接口直接删掉这条命令重启即可
三、VLT(类似于cisco的vss)
(一)做VLT的前提条件
1、所有单元都需要相同的FTOS 版本
2、Z9000最低OS版本为:8.3.10.2 (RTS release)
(二)VLT只支持交换机使用RSTP
(三)参数功能(某些可自动协商):
(四)指peer互联channel,协商VLT
(conf-vlt-domain)#peer-link port-channel
(五)提供备份链路,做健康检查
(conf-vlt-domain)#back-up destination
vlt配置实例
两台Z9000构成一个VLT域,Forty 0/120做为VLT备份链路,Forty 0/124绑成channel互指VLT Peer-Link形成VLTi关系。
Z9K-A:
vlt domain 1
peer-link port-channel 128
back-up destination 192.168.39.252
primary-priority 1

检查vlt和排错
检查VLT参数和Peer, Link状态
跨交换机链路捆绑命令
interface port-channel
vlt-peer-lag port-channel
实例:
4个10G口绑成一个channel(每台两个口)

no ip address

vlt-peer-lagport-channel 1
no shutdown
Z9K-B:
