Known Affected Releases
Symptom: When a Customer wants to configure more than 3k of data using the command "menu main prompt", the following error appears: "Maximum Banner size 3000 bytes reached. Banner message is truncated" If less than 3K & more than 2K of string length is configured with "menu main prompt" at the moment of saving the configuration to NVRAM, the following errors appears: % String too long to write to nvram (2932):Compressed configuration from 6104 bytes to 3386 bytes That message is being printed from the parser and is due to the menu being sent as 1 long continuous line (2932 bytes). The parser has a explicit check to make sure the line is not greater than MAX_NV_LINE which is set to 2048. So anything over 2048 will have this problem. There seems to be a disconnect with what the menu is defining as the max size (3k) and what the parser will allow (2k). The menu likely shouldn't be sending it as 1 complete line. Conditions: Every time the user wants to save more than 2K of output using the command "menu main prompt"
