Source IP Mask
Source IP Mask - Enter an IP address mask for the source IP address.
Destination IP Mask
Destination IP Mask - Enter an IP address mask for the destination IP
address.
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
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. The user may also identify which
flag bits to deny. 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).
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.

Packet Content Mask
