Sure, IOS is IOS is IOS, the same techniques apply. -rw-r--r-- 1 root code 132978980 Jul 29 08:34 c7600s72033-advipservicesk9-mz.122-33.SRD2a.bin -rw-r--r-- 1 root code 65403172 Jul 29 08:38 c7600s72033-advipservicesk9-mz.122-33.SRD2a-lan.bin The later image has had all the SIP/SPA and FlexWan type images removed, LAN cards only. You can reduce your boot time on the 6500/7600 platform by about 90-100 secs (depending on file size) if you can strip out the unnecessary images and make it fit onto the old 64MB linear bootflash rather than the modern ATA flash. The linear flash reads at 2MB/s while the ATA flash only reads at 1MB/s, so you reduce the "read the image into memory" time from 132 secs to 32 secs in the example above. This has been discussed on this list many times, search the archives. :) -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
