As to get the VLAN information, the file in Cisco devices Flash : Vlan.dat is fetced, and if PI fails to do so, it gives this error. As it is a file in flash, PI needs to send it over to Server itself using TFTP.
If TFPT is somehow not working between Server and devices, it may throw this error.
Is it happening with all the devices or some perticular platform?
If with all the device, you need to check if there is any Firewall blocking TFTP access to devices.
Also, you can check if TFTP service on CPI is working properly by command ncs status.
If service is affected, try to restart service - service tftp restart Or you can restart the PI Machine itself.
it doesnt happen on all of them, it happens on 108/150 of the devices. the rest of the devices seems to be only layer 3 devices (routers, fw's).
the tftp status seems to be alright:
Pais-CiscoPrime-01/admin# ncs status
Health Monitor Server is running.
Ftp Server is running
Database server is running
Tftp Server is running
Matlab Server is running
NMS Server is running.
Plug and Play Gateway is running.
SAM Daemon is running ...
DA Daemon is running ...
Syslog Daemon is running ...
i cant use the command - service tftp restart, there's no such command.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
