Figure 6 - 18. Add Access Rule window for IPv6
To set the Access Rule for IPv6, adjust the following parameters and click Apply.
Parameter Description
Access ID (1-200)
Type in a unique identifier number for this access. This value can be set from 1 to 200.
Auto Assign – Ticking this check box will instruct the Switch to automatically assign an Access ID
for the rule being created.
Action
Select Permit to specify that the packets that match the access rule are forwarded by the Switch,
according to any additional rule added (see below).
Select Deny to specify that packets that match the access rule are not forwarded by the Switch
and will be filtered.
Select Mirror to specify that packets that match the access rule are mirrored to a port defined in
the config mirror port command. Port Mirroring must be enabled and a target port must be set.
Priority (0-7)
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.
Replace Priority
Tick this check box to replace the Priority value in the adjacent field.
Replace DSCP (0-
63)
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.
Note: 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.
Class
Use this option to specify the IPv6 class mask.
