[c-nsp] NVRAM Size Limitations - Field Experiences?

[Mark Tinka]

Hello all.

We are slightly over 50% utilization on one of our router's NVRAM 
space (128KB on an NPE-300). 

We like to be pre-emptive way beforehand just so we don't shoot 
ourselves in the foot when crunch-time comes. So we are wondering 
whether to consider the 'service compress-config' feature to keep 
this router's running configuration manageable, or to upgrade to 
the NPE-G1 that has a lot more NVRAM (512KB, but certainly a 
"flimsy" reason to upgrade as the current NPE still has miles to 
go, CPU-wise).

www.cisco.com is unclear on NVRAM field upgrades (probably 
unlikely), but is clear on some caveats with compressing the 
configuration such as Boot ROMs that don't support the feature and 
truncation of running configurations.

This is a very busy edge router whose running configuration is only 
growing. What are others' experiences out in the field?

Mark.
