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. 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.
Select this option to instruct the Switch to replace the DSCP value (in a packet that meets the
selected criteria) with the value entered in the adjacent field.
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.
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.
The user may specify an IP address mask for the source IPv6 address by entering the IP
address mask, in hex form.
The user may specify an IP address mask for the destination IPv6 address by and entering the
IP address mask, in hex form.
The Access Rule may be configured on a per-port basis by entering the port number of the line
card in the chassis into this field. The port list is specified by listing the lowest line card number
and the beginning port number on that line card, separated by a colon. Then the highest line
card 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 line card number 1, port 3. 2:4 specifies line card number 2, port 4. 1:3 - 2:4
specifies all of the ports between line card 1, port 3 and switch 2, port 4 − in numerical order.
Entering all will denote all ports on the Switch.
