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
256.
Auto Assign – Tick the check box will instruct the Switch to automatically assign an
Access ID for the rule being created.
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.
Tick this check box 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.
Specify that the IP precedence of the outgoing packet is changed with the new value.
If used without an action priority, the packet is sent to the default TC.
Tick the check box and enter the name of the Time Range settings that has been
