0000 0111 .... OK that is 8 bits, which is equal to 1 Byte. 1 Byte is expressed as 2 hex characters. So take the first 4 bits (0000), convert it to hex and you get 0x0. Now, take 0111 and convert it to hex and you get 0x7. Now combine them, 0x07.
Regarding IP Precedence, it only uses the 3 most significant bits..... so 0000 0111 is still only IP Precedence = 0

Hmm, wouldn't 0x07 be precedences 0, 1 and 2? Actually I have reviewed my calculation and the answer i'm getting now is 0xE.

Hi,
I am not sure where you are getting 0x6F from 0000 0111. That would be 0x07

Subject: Access-list rate-limit mask
Hi guys
I want to create an access-list with only one line that matches IP
Precedence 3 and 6. I know my option is limited to using the ACL rate-limit
mask with a HEX value.
3 = 0000 0011
6 = 0000 0110
Is the answer to this
= 0000 0111 = 6F ?
access-list rate-limit 9 mask 6F
Your assistance will be appreciated.
