Configuring an Extended IP ACL
Command Attributes
•
Action
– An ACL can contain any combination of permit or deny rules.
•
Source/Destination Address Type
– Specifies the source or destination IP
address. Use “Any” to include all possible addresses, “Host” to specify a specific
host address in the Address field, or “IP” to specify a range of addresses with the
Address and SubMask fields. (Options: Any, Host, IP; Default: Any)
•
Source/Destination IP Address
– Source or destination IP address.
•
Source/Destination Subnet Mask
– Subnet mask for source or destination
address.
•
Service Type
– Packet priority settings based on the following criteria:
-
Precedence
– IP precedence level. (Range: 0-7)
-
TOS
– Type of Service level. (Range: 0-15)
-
DSCP
– DSCP priority level. (Range: 0-63)
•
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)
•
Source/Destination Port
– Source/destination port number for the specified
protocol type. (Range: 0-65535)
•
Source/Destination Port Bitmask
– 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
