思科WS-C6509-E核心交换机冗余引擎切换测试
V1.0
2010-12-10
1．首先查看引擎冗余状态：
WS-C6509-E_TJCore# wr
Building configuration...
1w0d: %PFINIT-SP-5-CONFIG_SYNC: Sync'ing the startup configuration to the standby Router. [OK]
WS-C6509-E_TJCore#show red
WS-C6509-E_TJCore#show redundancy
Redundant System Information :
------------------------------
Available system uptime = 1 week, 13 hours, 44 minutes
Switchovers system experienced = 0
Standby failures = 0
Last switchover reason = none
Hardware Mode = Duplex
Configured Redundancy Mode = sso
Operating Redundancy Mode = sso
Maintenance Mode = Disabled
Communications = Up
Current Processor Information :
-------------------------------
Active Location = slot 5
Current Software state = ACTIVE
Uptime in current state = 1 week, 13 hours, 43 minutes
Image Version = Cisco Internetwork Operating System Software
IOS (tm) s72033_rp Software (s72033_rp-IPSERVICES_WAN-M), Version 12.2(18)SXF3, RELEASE SOFTWARE (fc1)

Peer Processor Information :
----------------------------
Standby Location = slot 6
Current Software state = STANDBY HOT

通过查看可以得知引擎冗余采用的为SSO状态化切换模式，且Slot5为SUP1，Slot6为SUP2。
SUP1引擎模式为Active（活动状态），SUP2为Hot Standby模式。
在连接核心的一台PC上进行测试前的ping测试运行，具体操作机效果如下截图：
2．通过强制性切换，使SUP1引擎down掉。
使用redundancy force-switchover命令将SUP1 Down掉
WS-C6509-E_TJCore#redundancy force-switchover ?
WS-C6509-E_TJCore#redundancy force-switchover
This will reload the active unit and force switchover to standby[confirm]
Preparing for switchover..
1w0d: %SYS-SP-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.
1w0d: %OIR-SP-6-CONSOLE: Changing console ownership to switch processor
SUP1引擎将设备运行主动权交给SUP2，在测试前进行的ping测试截图如下：
SUP1引擎切换后从down状态转化到Hot Standby模式的过程如下：
1w0d: %SYS-SP-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.
1w0d: %SYS-SP-3-LOGGER_FLUSHED: System was paused for 00:00:00 to ensure console debugging output.
1w0d: %SYS-SP-3-LOGGER_FLUSHING: System pausing to ensure console debugging output.
