Figure 7-16 Add Access Rule (IPv6 ACL)
Description
Type in a unique identifier number for this access. This value can be set from 1 to 128.
Auto Assign – Select this check box will instruct the Switch to automatically assign an
Access ID for the rule being created.
Enter the IPv6 class mask value.
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.
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.
Select Mirror to specify that packets that match the access profile are mirrored to a port
defined in the config mirror port command. Port Mirroring must be enabled and a target
port must be set.
Tick the corresponding check 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 to replace the Priority value in the adjacent field.
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. When an ACL
rule is added to change both the priority and DSCP of an IPv6 packet, only one of them
can be modified due to a chip limitation. Currently the priority is changed when both the
priority and DSCP are set to be modified.
