一、註意點一
Z9000和4810類似,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將40G接口分割成4x10G接口
命令:Stack-unit 0 port X portmode quad 【x表示哪個接口】
(一)Qsfp是40g口,sfp+就是10g,sfp就是千兆也就是1g口。
(二)接口分割後需要重啟才會生效,需要恢復40G接口直接刪掉這條命令重啟即可
三、VLT(類似於cisco的vss)
(一)做VLT的前提條件
1、所有單元都需要相同的FTOS 版本
2、Z9000最低OS版本為:8.3.10.2 (RTS release)
(二)VLT隻支持交換機使用RSTP
(三)參數功能(某些可自動協商):
(四)指peer互聯channel,協商VLT
(conf-vlt-domain)#peer-link port-channel <LAG-ID> |
(五)提供備份鏈路,做健康檢查
(conf-vlt-domain)#back-up destination <ip-address> |
vlt配置實例
兩臺Z9000構成一個VLT域,Forty 0/120做為VLT備份鏈路,Forty 0/124綁成channel互指VLT Peer-Link形成VLTi關系。
Z9K-A: vlt domain 1 peer-link port-channel 128 back-up destination 192.168.39.252 primary-priority 1 unit-id 0 system-mac-address 00:11:22:33:44:55 interface fortyGigE 0/124 description To VLT peer - VLTi noip address port-channel-protocol LACP port-channel 128 mode active no shutdown interface fortyGigE 0/120 description To VLT peer - backup link ipaddress 192.168.39.251/24 no shutdown interface Port-channel 128 description VLT noip address no shutdown interface Vlan 1 untagged Port-channel 128 no shutdown |
Z9K-B: vlt domain 1 peer-link port-channel 128 back-up destination 192.168.39.251 primary-priority 8192 unit-id 1 system-mac-address 00:11:22:33:44:55 interface fortyGigE 0/124 description To VLT peer - VLTi noip address port-channel-protocol LACP port-channel 128 mode active no shutdown interface fortyGigE 0/120 description To VLT peer - backup link ipaddress 192.168.39.252/24 no shutdown interface Port-channel 128 description VLT noip address no shutdown interface Vlan 1 untagged Port-channel 128 no shutdown |
檢查vlt和排錯
檢查VLT參數和Peer, Link狀態
跨交換機鏈路捆綁命令
interface port-channel <id-number> vlt-peer-lag port-channel <id-number> |
實例:
4個10G口綁成一個channel(每臺兩個口)
Z9K-A:
interfacePort-channel 1 no ip address switchport channel-member TenGigabitEthernet 0/0-1 vlt-peer-lagport-channel 1 no shutdown Z9K-B: interfacePort-channel 1 no ip address switchport channel-member TenGigabitEthernet 0/0-1 vlt-peer-lagport-channel 1 no shutdown |
