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 appl y an IGMP type value
Select TCP to use the TCP port number contained in an incom ing packet as the forwardi ng
criterion. Selecting TCP requires that you specify a source por t mask and/or a destination
port mask. The user may also identify which flag bits to f ilter. Flag bits are parts of a p acket
that determine what to do with the packet. The user may filter packets by filtering certain f lag
bits within the packets, by checking the boxes corresponding to the flag bits of the TCP f ield.
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
0x0-0xffff), 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 pack et as the f orwarding
criterion. Selecting UDP requires that you specify a source port mask and/or a destin ation
port mask.
src port mask – Specify a TCP port mask for the source port in hex form (hex
0x0-0xffff) to be filtered.
dst port mask − Specify a TCP port mask for the destination port in hex form (hex
0x0-0xffff) to be filtered.
Protocol_id <0x0-0xff> – Enter a value defining the protocol ID in the packet header to
mask.
user_define_mask <hex 0x0-0xffffffff> – Enter a value defining the mask options behind
the IP header.
