Access Control Lists
3-75
•
Protocol
– Specifies the protocol type to match as TCP, UDP or Others, where
others indicates a specific protocol number (0-255). (Options: TCP, UDP, Others;
Default: TCP)
•
Src/Dst Port
– Source/destination port number for the specified protocol type.
(Range: 0-65535)
•
Src/Dst Bit Mask
– Decimal number representing the port bits to match. (Range:
0-65535)
•
Control Code
– Decimal number (representing a bit string) that specifies flag bits
in byte 14 of the TCP header. (Range: 0-63)
•
Control Code Bit Mask
– Decimal number representing the code bits to match.
The control bitmask is a decimal number (for an equivalent binary bit mask) that is
applied to the control code. Enter a decimal number, where the equivalent binary bit
“1” means to match a bit and “0” means to ignore a bit.
The following bits may be specified:
• 1 (fin) – Finish
• 2 (syn) – Synchronize
• 4 (rst) – Reset
• 8 (psh) – Push
• 16 (ack) – Acknowledgement
• 32 (urg) – Urgent pointer
For example, use the code value and mask below to catch packets with the following
flags set:
• SYN flag valid, use control-code 2, control bitmask 2
• Both SYN and ACK valid, use control-code 18, control bitmask 18
• SYN valid and ACK invalid, use control-code 2, control bitmask 18
