I have recently purchased an ISDN 8 port BRI card for a cisco 4000 router. This is for some of the labs I am doing. When i install the card the router appears to run out of I/O memory: Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 7F82DC 8420644 1552360 6868284 6701224 6845196 I/O 6000000 1048576 1048540 36 36 36 Without the card it looks like this: Processor 7F82DC 8420644 893604 7527040 7525024 7523020 I/O 6000000 1048576 613604 434972 434972 434972 More information: IOS (tm) 4000 Software (C4000-J-M), Version 11.2(14), RELEASE SOFTWARE (fc1) cisco 4000 (68030) processor (revision 0xA0) with 16384K/1024K bytes of memory.
