AT8901/2/3 Quality of Service (QoS) Commands

Page 4 - 25 AT8901/2/3 CLI Reference Manual

4.7.3 {deny | permit}

This command creates a new rule for the current MAC access list. Each rule is

appended to the list of configured rules for the list.

NOTE: The 'no' form of this command is not supported, since the rules within

a MAC ACL cannot be deleted individually. Rather, the entire MAC

ACL must be deleted and re-specified.

NOTE: An implicit 'deny all' MAC rule always terminates the access list.

NOTE: For BCM5630x and BCM5650x based systems, assign-queue, redi-

rect, and mirror attributes are configurable for a deny rule, but they

have no operational effect.

A rule may either deny or permit traffic according to the specified classification fields.

At a minimum, the source and destination MAC value must be specified, each of which

may be substituted using the keyword any to indicate a match on any value in that

field. The remaining command parameters are all optional, but the most frequently

used parameters appear in the same relative order as shown in the command format.

The Ethertype may be specified as either a keyword or a four-digit hexadecimal value

from 0x0600-0xFFFF. The currently supported

<ethertypekey> values are: appletalk,

arp, ibmsna, ipv4, ipv6, ipx, mplsmcast, mplsucast, netbios, novell, pppoe, rarp. Each

of these translates into its equivalent Ethertype value(s).

The vlan and cos parameters refer to the VLAN identifier and 802.1p user priority

fields, respectively, of the VLAN tag. For packets containing a double VLAN tag, this

is the first (or outer) tag.

The assign-queue parameter allows specification of a particular hardware queue for

handling traffic that matches this rule. The allowed <queue-id> value is 0-(n-1), where

n is the number of user configurable queues available for the hardware platform. The

assign-queue parameter is valid only for a permit rule.
