Cisco 2500 Upgrade to 16 MB

Post by Lowel » Wed, 05 Nov 2003 07:48:49



I just purchased some 16 MB simms for my Cisco 2501's and all looks pretty
good except one registers with 16348 of mem and the other only 14345 or
something to that effect.  So one sees the full 16 MB upgrade but the other
only 14 Mb.  Any suggestions?  Is this something I should worry about?  Only
for home use, study.

25xx routers reserve a portion of memory for I/O buffers and report the
two memory allocations separately as 16348/2084 or 14345/2039. In the
former case, you have an older 2501 with an additional 2MB of RAM on the
mainboard (when the 25xx first came out, 2M of RAM was more than
sufficient to support the IOS!).

As part of your home study, learn to search CCO and find a full
explanation of all the entries in a "show version."

Good luck and have fun!
