Click Apply to implement changes made.
Click Create to view the new CPU Access Profile List entry in the CPU Access Profile List window shown below. To
add another Access Profile click Add CPU ACL Profile. To delete a profile click the corresponding Delete button, to
view the specific configurations for an entry click the Show Details button. To add a rule to the CPU Access Profile
entry, click the Add/View Rules button.
Description
Enter an integer used to identify the access profile that will be configured with this
command.
Selecting this option instructs the Switch to examine the VLAN part of each packet header
and use this as the, or part of the criterion for forwarding.
Selecting this option instructs the Switch to examine the DiffServ Code part of each packet
header and use this as the, or part of the criterion for forwarding.
Tick either Source IP Mask and enter the IPv4 source address mask or Destination IP Mask
and enter the IPV4 destination address mask.
Tick ICMP to specify that the Switch will examine the Internet Control Message Protocol
(ICMP) field within each packet.
Tick ICMP Type to specify that the access profile will apply to this ICMP type value.
Tick ICMP Code to specify that the access profile will apply to this ICMP code value.
Tick IGMP to instruct the Switch to examine the Internet Group Management Protocol
(IGMP) field in each frame's header.
Tick IGMP Type to further specify that the access profile will apply an IGMP type
value.
Tick TCP to use the TCP port number contained in an incoming packet as the forwarding
criterion. Ticking TCP requires specifying a source port mask and/or a destination port
mask. The user may also identify which flag bits to filter. Flag bits are parts of a packet that
determine what to do with the packet. The user may filter packets by filtering certain flag bits
within the packets, by checking the boxes corresponding to the flag bits of the TCP field. T
Source Port Mask (0-FFFF) − Tick and specify a TCP port mask for the source port

to filter, in hex form (hex 0x0-0xffff).
Destination Port Mask (0-FFFF) − Tick and specify a TCP port mask for the

destination port to filter, in hex form (hex 0x0-0xffff).

TCP Flag Bits – Tick URG (urgent), ACK (acknowledgement), PSH (push), RST
(reset), SYN (synchronize), FIN (finish), or Check All to filter certain flag bits within
the packets.
Tick UDP to use the UDP port number contained in an incoming packet as the forwarding
criterion. Ticking UDP requires specifying a source port mask and/or a destination port
mask.
Source Port Mask − Tick and specify a TCP port mask for the source port to filter, in

hex form (hex 0x0-0xffff).
Destination Port Mask − Tick and specify a TCP port mask for the destination port to

filter, in hex form (hex 0x0-0xffff).
Tick Protocol ID Mask and enter a value defining the protocol ID in the packet header to
mask.
Protocol ID Mask (0-FF) − Tick and enter a value defining the mask options behind the
IP header.
User Define (0-FFFFFFFF) − Tick and enter a user-defined value.
