Hi, group,
I don't understand the function of the following configuration.
netbios access-list bytes engineering permit 20 AA**04
interface token 1
ipx netbios output-access-filter bytes engineering
When I look up the Command Reference, I found 20 is 'offset' and 'AA**04' is
'byte-pattern'.
offset means Decimal number that indicates the number of bytes into the packet
at which the byte comparison should begin. An offset of 0 indicates the beginni
ng of the NetBIOS packet header, which is at the end of the IPX header.
byte-pattern means Hexadecimal pattern that represents the byte pattern to matc
h. It can be up to 16 bytes (32 digits) long and must be an even number of digi
ts. The argument byte-pattern can include the double asterisk (**) wildcard cha
racter to match any digits for that byte.
Could anyone explain the 'offset' and 'byte-pattern' in a clearly understandabl
e way?
