How to query the version of the DC when the NMS server can only be logged in to through telnet?
Run the following commands after logging in to the server through telnet:
$ cd /opt/n2000/server/conf/about
$ cat dcver.cfg
ComponentName_zh =Data Centre
ComponentName_C = Data Center
ComponentVersion_zh = CMFV200R003B01D051SP01
ComponentVersion_C = CMFV200R003B01D051SP01
ComponentDesc_zh = Data Centre
ComponentDesc_C = Data Center
In this way, you can query the version of the DC.
If the DC has been patched, the version can be confirmed by querying the dcver_patch.cfg file.
