xStack® DGS-3200 Series Layer 2 Gigabit Ethernet Managed Switch The following parameters can be set for the IPv4 ACL type: Parameter Description Select Profile ID Use the drop-down menu to select a unique identifier number for this profile set. This value can be set from 1 to 200. Select ACL Type 802.1Q VLAN IPv4 DSCP IPv4 Source IP Mask IPv4 Destination IP Mask Protocol Select profile based on Ethernet (MAC Address), IPv4 address, IPv6 address, or packet content. This will change the window according to the requirements for the type of profile. Select Ethernet ACL to instruct the Switch to examine the layer 2 part of each packet header. Select IPv4 ACL to instruct the Switch to examine the IPv4 address in each frame's header. Select IPv6 ACL to instruct the Switch to examine the IPv6 address in each frame's header. Select Packet Content to instruct the Switch to examine the packet content in each frame's header. Selecting this option instructs the Switch to examine the 802.1Q VLAN identifier of each packet header and use this as the full or partial 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. Enter an IP address mask for the source IP address. Enter an IP address mask for the destination IP address. Selecting this option instructs the Switch to examine the protocol type value in each frame's header. Then the user must specify what protocol(s) to include according to the following guidelines: Select ICMP to instruct the Switch to examine the Internet Control Message Protocol (ICMP) field in each frame's header.  Select Type to further specify that the access profile will apply an ICMP type value, or specify Code to further specify that the access profile will apply an ICMP code value. Select IGMP to instruct the Switch to examine the Internet Group Management Protocol (IGMP) field in each frame's header.  Select Type to further specify that the access profile will apply an IGMP type value. Select TCP to use the TCP port number contained in an incoming packet as the forwarding criterion. Selecting TCP requires that you specify a source port mask and/or a destination port mask.  src port mask - Specify a TCP port mask for the source port in hex form (hex 0x00xffff), which you wish to match.  dst port mask - Specify a TCP port mask for the destination port in hex form (hex 0x0-0xffff) which you wish to match.  flag bit - The user may also identify which flag bits to match. 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. The user may choose among the urg (urgent), ack (acknowledgement), psh (push), rst (reset), syn (synchronize), and fin (finish) options.  Select UDP to use the UDP port number contained in an incoming packet as the forwarding criterion. Selecting UDP requires that you specify a source port mask and/or a destination port mask.  src port mask - Specify a UDP port mask for the source port in hex form (hex 0x00xffff). 185
