[. . . ] 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. 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), and fin (finish). src port mask - Specify a TCP port mask for the source port in hex form (hex 0x0-0xffff), 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 0x0-0xffff). dest port mask - Specify a TCP port mask for the destination port in hex form (hex 0x0-0xffff). protocol id - user value: Enter a value defining the protocol id in the packet header you wish to mask. Specify up to 5, Layer 4 port masks for the destination port in hex form (hex 0x0-0xffffffff). Dscp Protocol Port The user may set the Access Profile Table on a per-port basis by entering an entry in this field. Entering all will denote all ports on the Switch. The page shown below is the Packet Content Mask configuration window. 94 DES-3550 Layer 2 Fast Ethernet Switch User's Guide Figure 6- 43. Access Profile Configuration window (Packet Content Mask) This screen will aid the user in configuring the Switch to mask packet headers beginning with the offset value specified. The following fields are used to configure the Packet Content Masks: Parameter Profile ID(1-255) Description Type in a unique identifier number for this profile set. 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.
