• Protocol ID —Instead of selecting the name, enter the protocol ID.
• Source IP Address—Select Any if all source address are acceptable or User
Defined to enter a source address or range of source addresses.
• Source IP Address Value—Enter the IP address to which the source MAC address
is to be matched and its mask (if relevant).
• Source IP Wildcard Mask—Enter the mask to define a range of IP addresses.
Setting a bit as 1 indicates don't care and 0 indicates to mask that value.
Note—Given a mask of 0000 0000 0000 0000 0000 0000 1111 1111 (which
means that you match on the bits where there is 0 and don't match on the bits
where there are 1's). You need to translate the 1's to a decimal integer and you
write 0 for each four zeros. In this example since 1111 1111 = 255, the mask
would be written: as 0.0.0.255.
Destination IP Address—Select Any if all destination address are acceptable or
•
User Defined to enter a destination address or range of destination addresses.
Destination IP Address Value—Enter the IP address to which the destination IP
•
address is to be matched.
Destination IP Wildcard Mask—Enter the mask to define a range of IP addresses.
•
• Source Port—Select one of the following:
o Any—Match to all source ports.
o Single Port—Enter a single TCP/UDP source port to which packets are
matched. This field is active only if 800/6-TCP or 800/17-UDP is selected
in the Select from List drop-down menu.
Destination Port—Select one of the available values that are the same as the
•
Source Port field described above.
Note—You must specify the IP protocol for the ACE before you can enter the
source and/or destination port.
Type of Service—The service type of the IP packet.
•
o Any—Any service type
o DSCP to Match—Differentiated Serves Code Point (DSCP) to match
o IP Precedence to match—IP precedence is a model of TOS (type of service)
that the network uses to help provide the appropriate QoS commitments.
This model uses the 3 most significant bits of the service type byte in the
IP header, as described in RFC 791 and RFC 1349.
5. Click Apply. The IPv4-Based ACE is saved to the Running Configuration file.
