Creating an access profile is divided into two basic parts. The first is to specify which part or parts of a frame the switch
will examine, such as the MAC source address or the IP destination address. The second part is entering the criteria the
switch will use to determine what to do with the frame. The entire process is described below in two parts.
Figure 6- 58.
Access Profile Mask Setting window
To create an Access Profile Mask:
To add an entry to the
Access Profile Mask Setting
window, click the
New
button. This will open an
Access Profile Mask
Setting – Add
window, as shown below. There are three
Access Profile Mask Setting – Add
windows; one for Ethernet
(or MAC address-based) profile configuration, one for IP address-based profile configuration and one for the Packet
Content Mask. You can switch among the three windows by using the Access Profile drop-down menu.
Use the
Access Profile Mask Setting – Add
windows to create access profiles and specify what criteria are used to
examine frames. Once a profile has been created, you can set up the rule applied to the profile as described later in this
section.

The following parameters can be set, for the Ethernet type:
Parameter
Description
Profile ID
Type in a unique identifier number for this profile set. This value can be set from
1
to
8
.
Auto Assign
Checking this box instructs the Switch to automatically assign a Profile ID.
Access Profile
Select profile based on Ethernet (MAC Address), IP address or packet content mask.
This will change the window according to the requirements for the type of profile.
Ethernet
instructs the Switch to examine the layer 2 part of each packet header.
Select
IP
to instruct the Switch to examine the IP address in each frame's header.
Select
Packet Content Mask
to specify a mask to hide the content of the packet
header.
VLAN
Selecting this option instructs the Switch to examine the VLAN identifier of each
packet header and use this as the full or partial criterion for forwarding.
Source MAC
Source MAC Mask - Enter a MAC address mask for the source MAC address.
Destination MAC
Destination MAC Mask - Enter a MAC address mask for the destination MAC
address.
802.1p
Selecting this option instructs the Switch to examine the 802.1p priority value of each
packet header and use this as the, or part of the criterion for forwarding.
Ethernet Type
Selecting this option instructs the Switch to examine the Ethernet type value in each
frame's header.
Port
The user may set the
Access Profile Mask Setting
window
on a per-port basis by
entering a port number in this field. The port list is specified by listing the beginning
port number on that switch and the highest port number of the range. The beginning
and end of the port list range are separated by a dash. For example, 3-8 specifies all
of the ports between port 3 and port 8
−
in numerical order. Entering
all
will denote all
ports on the Switch.

Figure 6- 60.
Access Profile Mask Setting – Add (IP) window
The following parameters can be set, for IP:
Parameter
Description
Profile ID
Type in a unique identifier number for this profile set. This value can be set from
1
to
8
.
Auto Assign
Checking this box instructs the Switch to automatically assign a Profile ID.
Type
Select profile based on Ethernet (MAC Address), IP address or packet content mask.
This will change the window according to the requirements for the type of profile.
IP
instructs the Switch to examine the IP address in each frame's header.
Select
Ethernet
to instruct the Switch to examine the layer 2 part of each packet
header.
Select
Packet Content Mask
to specify a mask to hide the content of the packet
header.
VLAN
Selecting this option instructs the Switch to examine the VLAN part of each packet
header and use this as the, or part of the criterion for forwarding.

Source IP Mask
Enter an IP address mask for the source IP address.
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 filter by
checking the flag bit box. 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 among urg (urgent), ack (acknowledgement), psh (push), rst (reset),
syn (synchronize), and fin (finish).
Source Port Mask 0x - Specify a TCP port mask for the source port in hex form
(hex 0x0-0xffff), which you wish to filter.
Destination Port Mask 0x - 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.
Source Port Mask 0x - Specify a TCP port mask for the source port in hex form
(hex 0x0-0xffff).
Destination Port Mask 0x - Specify a TCP port mask for the destination port in hex
form (hex 0x0-0xffff).
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).
Port
The user may set the
Access Profile Mask Setting
window
on a per-port basis by
entering a port number in this field. The port list is specified by listing the beginning
port number on that switch and the highest port number of the range. The beginning
and end of the port list range are separated by a dash. For example, 3-8 specifies all
of the ports between port 3 and port 8
−
in numerical order. Entering
all
will denote all
ports on the Switch.

Access Profile Mask Setting – Add (Package Content Mask) window
This window will aid the user in configuring the Switch to mask packet headers beginning with the offset value specified.
The following fields are used to configure the Packet Content Mask:
Parameter
Description
Profile ID (1-8)
Type in a unique identifier number for this profile set. This value can be set from 1 - 8.
Auto Assign
Checking this box instructs the Switch to automatically assign a Profile ID.
Type
Select profile based on Ethernet (MAC Address), IP address or packet content mask.
This will change the menu according to the requirements for the type of profile.
Packet Content Mask
specifies a mask to hide the content of the packet header.
