目 录
本文档介绍了ISSU兼容和不兼容升级方式的配置举例。
ISSU(In-Service Software Upgrade,不中断业务升级)是一种可靠性高的升级设备启动软件的方式,可以在升级过程中做到业务不中断或中断时间较短。
进行ISSU升级前,请使用display version comp-matirx file命令查看设备将采用的ISSU升级策略,具体升级方式请见表1-1。
确认ISSU升级方式:
· 对于兼容版本升级,查看显示信息中的“Upgrade Way”字段。
· 对于非兼容版本升级,查看显示信息末尾部分,会显示“Incompatible upgrade”。
字段显示 |
|
兼容升级 |
Upgrade Way字段显示: · Service Upgrade · File Upgrade · ISSU Reboot · Reboot |
不兼容升级 |
Incompatible upgrade |
本文档中的配置均是在实验室环境下进行的配置和验证,配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置,为了保证配置效果,请确认现有配置和以下举例中的配置不冲突。
本文档假设您已了解ISSU特性。
· 请通过Console口对设备实施ISSU升级。如果通过Telnet或SSH登录设备实施ISSU升级,在升级过程中可能会因Telnet或SSH连接中断,导致ISSU升级无法继续。
· 硬件升级或故障期间,请不要进行ISSU升级。否则可能会导致升级失败或者系统异常。
· 请仔细阅读当前的软件版本和待升级软件版本的软件版本说明书,确认前后两个版本是否支持使用ISSU方式进行升级。
· 请通过display device命令了解设备的当前状态。请确保此时所有设备均为正常状态,对于故障设备请先行排除故障后,再进行ISSU升级。
· 请使用dir命令确认主控板/成员设备的存储介质有足够的空间来存放新的软件包/IPE文件。如果空间不足,请删除不需要的文件。
表3-1 ISSU升级和其他特性之间的关系
特性 |
要求 |
GR或NSR |
建议使能OSPF、ISIS、BGP和FSPF等协议的GR或NSR功能,否则ISSU升级期间可能会出现业务中断的现象 |
以太网链路聚合 |
所有动态聚合组的所有成员端口下LACP超时时间为长超时,即这些成员端口下都没有配置lacp period short命令 |
IRF |
· 如果需要对整个IRF进行兼容版本重启升级,请配置IRF桥MAC地址的保留时间为6分钟或永久保留 · 如果需要对整个IRF进行不兼容升级,并且IRF桥MAC地址为将执行issu load设备中的某台设备的MAC地址时,请在执行issu load命令前配置桥IRF桥MAC地址的保留时间为永久保留 · 如果需要对整个IRF进行不兼容升级,请先关闭IRF MAD 检测功能,完成ISSU升级后再重新配置 |
· ISSU升级期间,请确保网络拓扑稳定,禁止手工重启成员设备。
· ISSU升级期间,请确保系统中除了当前执行ISSU升级命令的用户外无其他用户登录。
· ISSU升级期间,请不要执行ISSU之外的配置命令,以免影响配置效果。
· 禁止对启动软件包进行修改、删除以及重命名等操作。
如图4-1所示,IRF由主设备和从设备组成。主设备的成员编号为1,主用主控板所在的槽位号为0,备用主控板所在的槽位号为1;从设备的成员编号为2,主用主控板所在的槽位号为0,备用主控板所在的槽位号为1。将Feature1软件包从R7723版本升级到兼容版本R7724。
图4-1 ISSU兼容升级组网图
本举例是在S7500XG-CMW710-R7724版本上进行配置和验证的。
升级前确保各成员设备的剩余存储空间大于等于新启动软件包大小的2倍。
