ACL Tab - MAC Based ACL

24-Port 10/100/1000 Gigabit Switch with Webview and PoE

Dest. IP Address.

Matches the destination port IP address to which packets are addressed to the ACE.

Wildcard Mask.

Defines the destination IP address wildcard mask.

Match DSCP.

Matches the packet DSCP value to the ACE. Either the DSCP value or the IP Precedence value is

used to match packets to ACLs. The possible field range is 0-63.

Match IP Precedence.

Matches the packet IP Precedence value to the ACE. Either the DSCP value or the IP

Precedence value is used to match packets to ACLs. The possible field range is 0-7.

The

Add to List

button adds the configured IP Based ACLs to the IP Based ACL Table at the bottom of the screen.

ACL Tab - MAC Based ACL

The MAC Based ACL screen allows a MAC based ACL to be defined. ACEs can be added only if the ACL is not
bound to an interface.

Target

. Select the New ACL Name radio button and enter an ACL name in the text field provided (with up to 16

characters). Or to add rules to an existing ACL select the ACL Name radio button and select an ACL from the
dropdown menu.

ACL Name.

Displays the user-defined MAC based ACLs.

New ACL Name.

Specifies a new user-defined MAC based ACL name, the name cannot include spaces.

Action.

Indicates the ACL forwarding action. Possible field values are:

•

Permit.

Forwards packets which meet the ACL criteria.

•

Deny.

Drops packets which meet the ACL criteria.

•

Shutdown.

Drops packet that meet the ACL criteria, and disables the port to which the packet was

addressed.

Source MAC Address.

Matches the source MAC address to which packets are addressed to the ACE.

Wildcard Mask.

Defines the source IP address wildcard mask. Wildcard masks specify which bits are used and

which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of
0.0.0.0 indicates that all the bits are important. For example, if the source IP address 149.36.184.198 and the
wildcard mask is 255.36.184.00, the first eight bits of the IP address are ignored, while the last eight bits are
used.
