Protocol
Port
To establish the rule for a previously created Access Profile:
In the Configuration folder, click the Access Profile Table link opening the Access Profile Table. Under the
heading Access Rule, clicking Modify, will open the following window.
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 cod 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), 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 − Specify a Layer 4 port mask for the destination port in hex
form (hex 0x0-0xffffffff).
The user may set the Access Profile Table on a per-port basis by
entering an entry in this field. The user may select all, denoting all ports
within the switch stack, or enter a port or ports. The port list is specified by
listing the lowest switch number and the beginning port number on that
switch, separated by a colon. Then the highest switch number, and the
highest port number of the range (also separated by a colon) are specified.
The beginning and end of the port list range are separated by a dash. For
example, 1:3 specifies switch number 1, port 3. 2:4 specifies switch
number 2, port 4. 1:3-2:4 specifies all of the ports between switch 1, port 3
and switch 2, port 4 − in numerical order.
