On a certain day, due to the maintenance needs, the representative office engineer carries out the hot patch loading of NGSDH equipment, the NGSDH host version of the existing network is V1R8C02SPC200, according to the version policy,it is necessary to load R8C02SPH203 (hot patch), the equipment involved includes: OSN7500/3500/1500. the existing network network management version includes: U2000V100R002C01SPC503 and T2000V200R007C03SPC007, T2000V200R008C00SPC001.
Problems exist:
After the OSN7500 device is upgraded through (package loading method), the network management query result shows normal except that after the other network elements are upgraded (board level loading method) OSN1500 and OSN3500 can not query the information related to the hot patch version SPH203 on the network management, and the query display shows only SPC200.
Warning Message Processing2、Multiple versions of the network management have the problem, and the OSN7500 device package loading method is displayed normally on the network management, which can rule out the network management problem;
3、After the final analysis confirms that this problem is a problem with the network management display:
The network management to view the patch version of the command issued by the network management : : : patchpkg-get-pkginfo:all patchpkg-get-pkginfo:all This command is only suitable for the hot patch package loading method, and it does not support checking the hot patches loaded at the board level.
The main control boards of different hardware versions of NGSDH equipment support different hot patch loading methods. NG-SDH products initially only support board-level hot patch function, V100R008 starts to support both board-level hot patch and patch package function (different main control types support different hot patch upgrade methods), and only patch package function is supported in V100R009 and later versions.
Therefore, the network elements (OSN1500 and OSN3500) upgraded by the board-level loading method on the site cannot query the software version patch version on the network management. Use the single-board patch query command to check the hot patch loading situation of the equipment: patch-get-statemsg:BID (master slot) to verify that the hot patch loading on the site is normal.
Avoidance measures:
1. Use the DC tool to correctly display the patch information that has been loaded on the device in the network element software management-patch software loading interface. (The DC tool integrated with the network management also supports this).
2. Use the single-board patch query command to view the hot patch loading status of the device: patch-get-statemsg:BID (master slot) to verify the patch loading status on site.
3, the use of inspection tools can be the whole network equipment for hot patch loading inspection, inspection tools have a separate inspection of this feature entry.
Root Cause2、Network management defects
3、Network management and equipment with the problem
