what is a good value for the log buffer? C850 series

Hi all!

I recently upgraded my C857 memory from 64Mb to 128Mb.
(The 850 series have a memory slot, where you can place in a PC133
DIMM - just make sure it is a low profile dimm)

I was inspired by this article: (I used a low profile dimm -- no need
te cut the metal frame) At your own risk!
http://www.instructables.com/id/Adding-Off-The-Shelf-Memory-to-a-Cisco-871/

I have a picture of the inside if someone is interested.

It now boots up with:

"System Bootstrap, Version 12.3(8r)YI4, RELEASE SOFTWARE
Technical Support: http://www.cisco.com/techsupport
Copyright (c) 2006 by cisco Systems, Inc.

C850 series (Board ID: 2-149) platform with 131072 Kbytes of main
memory"




No, to actually do something usefull with the extra ram
I want to increase the log buffer a bit.
How much should I set it with 128Mb ram?
I've set it to 20k for now

My device is als configered as DNS forwarder (to my ISP's upstream DNS
servers)
Can I set the DNS cache time out a bit higher?

20K for logging buffer should suffice

Thanks!

you have around 74 Megs of free memory

 

But you probably don't want to dedicate 74MB to the log buffer.

On our fairly busy 6500s we have the log buffer up at 128KB, which is
sometimes useful but can also be a pain to scroll through to the end.

Hi there!

Thanks for the tip.
Seems a good amound to me.
The log fills up with 7-12K/day
so 128K wil give me a +- week or more

More then enough
Thx!

You can also set up a syslog server to retain all loggin info for a
long period of time.

I like the logging buffer so that I can quickly find recent messages
