1267.0. "Configuration Buffer Problems" by CHEFS::BROWN_D () Tue Feb 04 1997 04:25

    I'm trying to add more routing definitions in a DECbrouter T2A at a 
    customer but when trying to Write Memory get "Configuration Buffer is
    full..." messages.  I assume this means the unit has run out of NVRAM
    space.  Is this true?
    
    Questions:
    - are there any memory uprades possible
    - is the memory partitioned in any way, for example between routing
    protocols, or is it a free for all.  For example if I find any config.
    lines that I think can be deleted will this free space for any other
    sort of config. info.
     
    Model no. is DEWB2-NA, Software version is 10.2.
    
    regards

1267.1Check your Rev and memory allocationFOUNDR::SHEEHANTue Feb 11 1997 15:3748
 Hi Dennis,

 Here's some info from Cisco's WEB Site on the Error
 you're possibly seeing.

Configuration memory full error message appears.

     Adding too many configuration commands will cause
     earlier commands to be lost and 
the following error
     message to appear: 

% Configuration buffer full, can't add command: user command

     This error indicates that the configuration memory limit
     has been reached and earlier
 working commands may be
     lost if you proceed. 

    >Questions:
    >- are there any memory uprades possible

    What Rev. is the DECbrouter? This will be listed on
    the back under the Serial number. If its a Rev B you
    are limited. If its a rev. C you can run 11.1 which
    has a config setting for allocating more memory for
    the processor.
    
    >- is the memory partitioned in any way, for example
    >   between routing protocols, or is it a free for all.

    As far as how much memory is used for storage of the
    configuration commands I don't know with 10.2 but with
    11.1 The default is 25% for packet memory and 75% for
    processor memory. Unfortunately ther is no way of
    modifying this partitioning with 10.2.

    >For example if I find any config. lines that I think can

    > config. info.

    It should! do a show memory and look at the Processor Free
    memory entry. Then remove the config entries wr mem then
    reload. Then do a show mem again and see if you've free'd
    up any processor memory.

     This error indicates that the configuration memory limit

     Do not use the write memory or copy running-config command
     if this error message appears. [CSCdi54713] 

    >Questions:
    >- are there any memory uprades possible

    As far as how much memory is used for storage of the
    configuration commands I don't know. But if you do
    a show config the first line should show you how many
    bytes are being used

    Ex...

    SHOW CONFIG

    Using 1212 out of 32762 bytes
     

    >For example if I find any config. lines that I think can
    >be deleted will this free space for any other sort of
    >config. info.

    It should! You may want to do a COPY RUNNING-CONFIG using
    RCP or TFTP also COPY STARTUP-CONFIG to save your config
    files to a remote location edit the file to remove any commands
    you don't need. Then clear the NVRAM by doing a WRITE ERASE.
    Then perform a COPY RCP STARTUP-CONFIG or CONFIG NET of the file
    you edited to load the edited Config file into NVRAM. If sucessfull
    then A CONFIG MEM or reload will then need to be done to write the
    new config to the running config.

Some helpful info....
