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 IGMP to instruct the Switch to examine the Internet Group Management Protocol
(IGMP) field in each frame's header.
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 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).
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.
protocol id - Enter a value defining the protocol ID in the packet header to mask. Specify
the protocol ID mask in hex form (hex 0x0-0xffffffff).
