Advanced Configuration

Source Port  Defines the TCP/UDP source port to which the ACE is matched. This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0–65,535.

Destination Port  Defines the TCP/UDP destination port. This field is active only if 800/6-TCP or 800/17-UDP are selected in the Select from List drop-down menu. The possible field range is 0–65,535.

Source IP Address  Matches the source port IP 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.

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 > 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.

ACL > Mac Based ACL

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.

Delete ACL  Deletes the selected ACL.

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.

Dest. MAC Address  Matches the destination MAC address to which packets are addressed to the ACE.

•• Wildcard Mask  Defines the destination IP address wildcard mask.

VLAN ID  Matches the packet’s VLAN ID to the ACE. The possible field values are 2–4094.
