Parameter xStack DES-3500 Series Layer 2 Stackable Fast Ethernet Managed Switch User Manual Description Profile ID (1-255) Type in a unique identifier number for this profile set. The number is used to set the relative priority for the profile. Priority is set relative to other profiles where the lowest profile ID has the highest priority. If a conflict occurs among configured access rules, the profile ID establishes relative priority of the rules. The value can be set from 1 to 255 however there is a limit to the total number of profiles that can be created. Type Select profile based on Ethernet (MAC Address), IP address or packet content mask. This will change the menu according to the requirements for the type of profile. • Select Ethernet to instruct the Switch to examine the layer 2 part of each packet header. • Select IP to instruct the Switch to examine the IP address in each frame's header. • Select Packet Content Mask to specify a mask to hide the content of the packet header. VLAN 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. Source IP Mask Enter an IP address mask for the source IP address. Destination IP Mask Enter an IP address mask for the destination IP address. DSCP 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. Protocol Selecting this option instructs the Switch to examine the protocol type value in each frame's header. You must then 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. The user may also identify which flag bits to deny. Flag bits are parts of a packet that determine what to do with the packet. The user may deny packets by denying certain flag bits within the packets, by checking the boxes corresponding to the flag bits of the TCP field. The user may choose between urg (urgent), ack (acknowledgement), psh (push), rst (reset), syn (synchronize), fin (finish). • src port mask - Specify a TCP port mask for the source port in hex form (hex 0x00xffff), which you wish to deny. • dest port mask - Specify a TCP port mask for the destination port in hex form (hex 0x0-0xffff) which you wish to deny. 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 TCP port mask for the source port in hex form (hex 0x00xffff). • dest port mask - Specify a TCP port mask for the destination port in hex form (hex 0x0-0xffff). protocol id - Enter a value defining the protocol ID in the packet header to mask. Specify up to 5, Layer 4 port masks for the destination port in hex form (hex 0x0-0xffffffff). The window shown below is the Access Profile Configuration window for Packet Content Mask. 83
