In VSM, add network element successfully. Choose “network element” and right click “NE explorer”, service tree> port management> port information, click “query”, but failed and alarmed “fail to obtain parameter of telnet/ssh”.
Chose “synchronize network element data”, finished synchronization and queried again, can see the parameter of interface.
1. Checked the device-side setting of telnet/ssh.
2. When device has configured telnet/ssh, checked the configuration of telnet/ssh in VSM.
3. When two-side parameters of telnet/shh is same, if VSM still cannot query the interface information, the reason may be that network element data isn’t synchronized.
After adding network element in VSM, configure the two-side parameter of telnet/ssh correctly, and synchronize to VSM server.
