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 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
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 packet as the forwarding
criterion. Selecting UDP requires that you specify a source port mask and/or a destination
port mask.
src p ort m ask −
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..
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.
