This attribute is used to specify a set of VLAN IDs against which the traffic being classified is compared. Packets that contain a VLAN ID equal to one of the VLAN IDs in this set match this component of an 802 filter. The format of this octet string is a series of two-byte (16 bit) values with each octet tuple identifying a single VLAN ID in the set. Therefore, the length of the octet string value of this object is always either zero or an even number of octets (e.g., 2, 4, 6, 20). As with most sets, ordering within the set (octet string) is unimportant. For example, a set specifying three VLAN IDs (8, 35 and 4012) might be specified as follows: Octets: 1 | 2 | 3 | 4 | 5 | 6 Values: 0x00 | 0x23 | 0x00 | 0x08 | 0x0F | 0xAC VLAN ID: 35 | 8 | 4012 The supported maximum length of this attribute depends on the maximum number of VLANs that may be included in a set for filtering purposes. This length is thus implementation dependent. Note that this attribute and the qos802AceVlanId attribute are mutually exclusive. The value of the qos802AceVlanId component of the augmented filter entry must be set to 'ignore' (i.e., -1) if the length of this set is non-zero. Otherwise entry creation will fail.
