7. QoS Access Lists (ACL)

As of software release 5.0, the ERS 55xx can be configured using access lists (ACL). You can choose to
use policies and/or ACLs to configure the ERS 5500 switch. Up to a maximum of 15 precedence levels
are supported using policies whereas ACL‟s allows up to a maximum of 8 precedence levels.
Please be aware of the following when using ACLs:
By default, ACLs are always terminated by an implicit action of "drop all non-matching traffic". The
default action of "drop all non-matching traffic" cannot be changed.
ACL precedence is always in the order the ACLs are ent ered
ACLs are applied at a port level
Up to 8 precedence levels are supported, however, you can use A CL blocks if you have similar
filter rules - please see classifier block explanation in section 3. 2
When an A CL is assigned to a port, the ACL is assigned the highest precedence value available
on the port. Each additional A CL that is added is then assigned decreasing precedence levels.
Any policies (QoS or non-QoS) already associated with a port dictate the starting and subsequent
precedence values for the ACL(s).
You cannot assign traffic meters
IP and L2 ACLs cannot be combined. If you wish to combine L2 and L3, policies must be used
ACLs cannot be modified; you must first remove the ACL-assign configuration at a port level, then
delete the ACL or ACLs you wish to modify and reconfigure the ACL or A CLs.
ACLs can be enabled or disabled. However, you cannot update or change the associated
precedence values when the ACL is disabled.
You can only configure ACLs using CLI or http (QoS Wizard). Although JDM will display the ACL
configuration, you cannot use JDM to either configure or delet e ACL‟s.
