IPv4-based ACL Creation

Cisco 350, 350X and 550X Series Managed Switches, Firmware Release 2.4, ver 0.4 401

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.

• Source MAC Address—Select Any if all source address are acceptable or User defined

to enter a source address or range of source addresses.

• Source MAC Address Value—Enter the MAC address to which the source MAC

address is to be matched and its mask (if relevant).

• Source MAC Wildcard Mask—Enter the mask to define a range of MAC addresses.

• VLAN ID—Enter the VLAN ID section of the VLAN tag to match.

• 802.1p—Select Include to use 802.1p.

• 802.1p Value—Enter the 802.1p value to be added to the VPT tag.

• 802.1p Mask—Enter the wildcard mask to be applied to the VPT tag.

• Ethertype—Enter the frame Ethertype to be matched.

STEP 5 Click Apply. The MAC-based ACE is saved to the Running Configuration file.

IPv4-based ACL Creation

IPv4-based ACLs are used to check IPv4 packets, while other types of frames, such as ARPs,

are not checked.

The following fields can be matched:

• IP protocol (by name for well-known protocols, or directly by value)

• Source/destination ports for TCP/UDP traffic

• Flag values for TCP frames

• ICMP and IGMP type and code

• Source/destination IP addresses (including wildcards)

• DSCP/IP-precedence value

NOTE ACLs are also used as the building elements of flow definitions for per-flow QoS handling.
