S6800+堆叠升级

你可以看下以下案例是否符合你的需求：建议申请变更时间

•  交换机IRF场景下业务中断时间最短的升级方法(假定tftp服务器地址为10.0.0.1)。

•  1、备份当前配置，并根据实际情况查看设备运行信息

                  <H3C>save backup.cfg

                  <H3C>dir

<H3C>tftp 10.0.0.1 put backup.cfg

<H3C>dis version

<H3C>dis interface brief

<H3C>dis ip routing-table

<H3C>dis link-aggregation verbose

<H3C>dis irf

<H3C>dis mad verbose

•  2、查看各主控板flash空间是否充足：

<H3C>dir

<H3C>dir chassis1#slot2#flash:/

<H3C>dir chassis2#slot1#flash:/

<H3C>dir chassis2#slot2#flash:/

•  3、上传并指定下次启动版本

<H3C>tftp 10.0.0.1 get S10500-CMW710-R7524P01.ipe

<H3C>dir

<H3C>boot-loader file flash:/S10500-CMW710-R7524P01.ipe all main

<H3C>dis boot-loader(确保各主控下次启动文件指定成功再向下进行)

•  4、关闭MAD检测（以BFD MAD为例）

[H3C]int Vlan-interface 4094

[H3C-Vlan-interface4094]dis this

[H3C-Vlan-interface4094]undo mad bfd enable

[H3C-Vlan-interface4094]dis this

•  5、关闭主框业务口并保存配置

[H3C]int range name yw1 interface Ten-GigabitEthernet 1/0/0/1 to Ten-GigabitEthernet 1/0/0/48 Ten-GigabitEthernet 1/9/0/1 to Ten-GigabitEthernet 1/9/0/48

[H3C-if-range-yw1]shutdown

[H3C-if-range-yw1]save

•  6、重启主框，并在主框启动完成之前拔掉堆叠线

<H3C>reboot chassis 1

•  7、关闭备框业务口，再打开主框业务口（先shutdown 备框接口，再undo shutdown主框接口，间隔越短，业务中断时间越短，建议提前写好脚本）

备框：

[H3C]int range name yw2 interface Ten-GigabitEthernet 2/0/0/1 to Ten-GigabitEthernet 2/0/0/48 Ten-GigabitEthernet 2/9/0/1 to Ten-GigabitEthernet 2/9/0/48

[H3C-if-range-yw2]shutdown

主框：

[H3C]int range name yw1

[H3C-if-range-yw1]undo shutdown

•  8、确认主框业务正常运行后，重启备框，在备框重启完成之前插上堆叠线(重启备框的时候不要选择保存配置)

< H3C >reboot chassis 2

•  9、确认业务是否正常，同时查看并对比升级前记录的设备运行信息

<H3C>dis version

<H3C>dis interface brief

<H3C>dis ip routing-table

<H3C>dis link-aggregation verbose

<H3C>dis irf

•  10、恢复MAD检测（以BFD MAD为例）

[H3C]int Vlan-interface 4094

[H3C-Vlan-interface4094]dis th

[H3C-Vlan-interface4094]mad bfd enable

[H3C-Vlan-interface4094]mad ip address 21.96.254.1 255.255.255.252 member 1

[H3C-Vlan-interface4094]mad ip address 21.96.254.2 255.255.255.252 member 2

[H3C-Vlan-interface4094]dis th

[H3C-Vlan-interface4094]save

<H3C>dis mad verbose
