Description
This command configures matching packets with a specific IP option or a range of IP options in the
IP header as an IP filter match criterion.
The option-type octet contains 3 fields:
• 1 bit copied flag (copy options in all fragments)
• 2 bits option class,
• 5 bits option number.
The
no
form of the command removes the match criterion.
Default
No IP option match criterion
Parameters
ip-option-value —
Enter the 8 bit option-type as a decimal integer. The mask is applied as an AND to
the option byte, the result is compared with the option-value.
The decimal value entered for the match should be a combined value of the eight bit option type
field and not just the option number. Thus to match on IP packets that contain the Router Alert
option (option number =20), enter the option type of 148 (10010100).
