xStack® DGS-3400 Series Layer 2 Gigabit Ethernet Managed Switch 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 a source port mask and/or a destination port mask is to be specified. 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. 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 filter. • dst port mask - Specify a TCP port mask for the destination port in hex form (hex 0x0-0xffff) which you wish to filter. 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). • dst port mask - Specify a UDP 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 the protocol ID mask in hex form (hex 0x0-0xff). Click Apply to set this entry in the Switch's memory.
