xStack DGS-3400 Series Fast Ethernet Switch
To set the Access Rule for the Packet Content Mask, adjust the following parameters and click Apply.
Parameter Description
Profile ID
This is the identifier number for this profile set.
Mode
Select Permit to specify that the packets that match the access profile are
forwarded by the Switch, according to any additional rule added (see below).
Select Deny to specify that packets that match the access profile are not forwarded
by the Switch and will be filtered.
Access ID
Type in a unique identifier number for this access rule. This value can be set from 1
- 128.
Type
Selected profile based on Ethernet (MAC Address), IP address or IPv6 address
Ethernet instructs the Switch to examine the layer 2 part of each packet header.
IP instructs the Switch to examine the IP address in each frame's header.
IPv6 instructs the Switch to examine the IPv6 address in each frame's header.
Priority
This parameter is specified to re-write the 802.1p default priority previously set in
the Switch, which is used to determine the CoS queue to which packets are
forwarded to. Once this field is specified, packets accepted by the Switch that
match this priority are forwarded to the CoS queue specified previously by the user.
Replace priority with − Click the corresponding box to re-write the 802.1p default
priority of a packet to the value entered in the Priority field, which meets the criteria
specified previously in this command, before forwarding it on to the specified CoS
queue. Otherwise, a packet will have its incoming 802.1p user priority re-written to
its original value before being forwarded by the Switch.
For more information on priority queues, CoS queues and mapping for 802.1p, see
the QoS section of this manual.
Class
Entering a value between 0 and 255 will instruct the Switch to examine the class
field of the IPv6 header. This class field is a part of the packet header that is similar
to the Type of Service (ToS) or Precedence bits field of IPv4.
Flowlabel
Configuring this field, in hex form, will instruct the Switch to examine the flow label
field of the IPv6 header. This flow label field is used by a source to label sequences
of packets such as non-default quality of service or real time service packets.
Source IPv6 Address
The user may specify an IP address mask for the source IPv6 address by entering
the IP address mask, in hex form.
Destination IPv6 Address
The user may specify an IP address mask for the destination IPv6 address by and
entering the IP address mask, in hex form.
Port
The Access Rule may be configured on a per-port basis by entering the port
number of the switch.
Rx rate
A limit may be set on the incoming rate for the access rule.
