How do you get round this when trying to specify devices for dhcp based on MAC address
mac access-list extended RUCKUS
deny F0B0.5200.0000 0000.00FF.FFFF any
deny E010.7F00.0000 0000.00FF.FFFF any
deny D468.4D00.0000 0000.00FF.FFFF ...
I found that the only way is like this boot system
bootflash:asr1001-universalk9.03.07.01.S.152-4.S1.bin
i.e leave out the flash as if you check the image in use with the word flash used it will still be on an older image.
