Thank you so much for your cooperation

Problem of NVRAM Size on Cisco7606-S


Actually you are not seeing a problem at all because the design itself is such by Cisco for some internal reasons.

So you need not be worried about that. If you need to check the actualy size of the NVRAM on the device (both Active & Standby RSP), kindly use the command "show file system". This would give you accurate results.
