1 简介

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命令查看升级待升级启动软件包时需要使用的升级方式，使用该命令后，会在Upgrade Way中显示升级方式，具体升级方式请见表1。

表1 升级方式和显示参数对应表

2 配置前提

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。

3 使用限制

1. ISSU升级对硬件的要求

· 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。

2. ISSU升级需要满足的条件

· 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。

· 请通过display mdc命令查看MDC的状态，确保所有MDC的状态均为active才可以进行ISSU升级，否则可能导致该设备升级异常。

· 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。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。

3. ISSU升级和其他特性之间的限制关系

表2 ISSU升级和其他特性之间的关系

特性	要求
GR或NSR	建议使能LDP、RSVP、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
BFD	建议去使能LDP、RSVP、OSPF、ISIS、RIP、BGP、VRRP、NQA等协议的BFD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	· 通过link-delay命令将以太网接口物理连接状态抑制时间设置为0秒，即不抑制，当接口状态发生改变时立即上报CPU · 请使能聚合流量重定向功能，确保聚合链路上的流量不中断 · 请配置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

4. ISSU升级期间的操作限制

· ISSU升级期间，请确保网络拓扑稳定，禁止手工重启单板和插拔单板。

· 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。

4 兼容升级典型配置举例

4.1.1 组网需求

如图1所示，IRF由两台成员设备组成，现要求使用ISSU方式进行成员设备的升级，将设备启动软件包由R7150版本升级到7585P05版本。
