1 簡介

本文檔介紹了ISSU兼容和不兼容升級方式的配置舉例。

ISSU（In-Service Software Upgrade，不中斷業務升級）是一種可靠性高的升級設備啟動軟件的方式，可以在升級過程中做到業務不中斷或中斷時間較短。

進行ISSU升級前，請使用display version comp-matirx命令查看升級待升級啟動軟件包時需要使用的升級方式，使用該命令後，會在Upgrade Way中顯示升級方式，具體升級方式請見表1。

表1 升級方式和顯示參數對應表

升級方式	Upgrade Way字段顯示參數
兼容升級	· Service Upgrade · File Upgrade · Reboot
不兼容升級	Incompatible upgrade

2 配置前提

本文檔中的配置均是在實驗室環境下進行的配置和驗證，配置前設備的所有參數均采用出廠時的缺省配置。如果您已經對設備進行了配置，為了保證配置效果，請確認現有配置和以下舉例中的配置不衝突。

本文檔假設您已了解ISSU特性。

3 使用限製

1. ISSU升級對硬件的要求

· 請通過Console口對設備實施ISSU升級。如果通過Telnet或SSH登錄設備實施ISSU升級，在升級過程中可能會因Telnet或SSH連接中斷，導致ISSU升級無法繼續。

· 硬件升級或故障期間，請不要進行ISSU升級。否則可能會導致升級失敗或者係統異常。

2. ISSU升級需要滿足的條件

· 請仔細閱讀當前的軟件版本和待升級軟件版本的軟件版本說明書，確認前後兩個版本是否支持使用ISSU方式進行升級。

· 請通過display device命令了解設備的當前狀態。請確保此時所有設備均為正常狀態，對於故障設備請先行排除故障後，再進行ISSU升級。

· 請通過display mdc命令查看MDC的狀態，確保所有MDC的狀態均為active才可以進行ISSU升級，否則可能導致該設備升級異常。

· 升級前確保各成員設備的剩餘存儲空間大於等於新啟動軟件包大小的2倍。請使用dir命令確認主控板/成員設備的存儲介質有足夠的空間來存放新的軟件包/IPE文件。如果空間不足，請刪除不需要的文件。

3. ISSU升級和其他特性之間的限製關係

表2 ISSU升級和其他特性之間的關係

特性	要求
GR或NSR	建議使能LDP、RSVP、OSPF、ISIS、BGP和FSPF等協議的GR或NSR功能，否則ISSU升級期間可能會出現業務中斷的現象
BFD	建議去使能LDP、RSVP、OSPF、ISIS、RIP、BGP、VRRP、NQA等協議的BFD功能，否則ISSU升級期間可能會出現業務中斷的現象
以太網鏈路聚合	所有動態聚合組的所有成員端口下LACP超時時間為長超時，即這些成員端口下都沒有配置lacp period short命令
IRF	· 通過link-delay命令將以太網接口物理連接狀態抑製時間設置為0秒，即不抑製，當接口狀態發生改變時立即上報CPU · 請使能聚合流量重定向功能，確保聚合鏈路上的流量不中斷 · 請配置IRF橋MAC地址的保留時間為永久保留 · 如果需要對整個IRF進行不兼容升級，請先關閉IRF MAD 檢測功能，完成ISSU升級後再重新配置

4. ISSU升級期間的操作限製

· ISSU升級期間，請確保網絡拓撲穩定，禁止手工重啟單板和插拔單板。

· ISSU升級期間，請確保係統中除了當前執行ISSU升級命令的用戶外無其他用戶登錄。

· ISSU升級期間，請不要執行ISSU之外的配置命令，以免影響配置效果。

· 禁止對啟動軟件包進行修改、刪除以及重命名等操作。

4.1.1 組網需求

如圖1所示，IRF由兩台成員設備組成，現要求使用ISSU方式進行成員設備的升級，將設備啟動軟件包由R7150版本升級到7585P05版本。
