Figure 7-21 Add Access Rule (Packet Content ACL)
The fields that can be configured are described below:
Parameter
Description
Access ID (1-256)
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.
Action
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 the 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.
Priority (0-7)
Tick the corresponding check box if you want 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. When an
ACL rule is added to change both the priority and DSCP of an IPv4 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.
