Key Parameters
◆ Tag – VLAN tag type. (Options: Any, Tag, Untag; Default: Any)
◆ VID – VLAN identifier. (Options: Any, Specific (1-4095), Range;
Default: Any)
◆ PCP – Priority Code Point (User Priority). (Options: a specific value of
0, 1, 2, 3, 4, 5, 6, 7, a range of 0-1, 2-3, 4-5, 6-7, 0-3, 4-7, or Any;
Default: 0)
◆ DEI – Drop Eligible Indicator. (Options: 0, 1 or Any)
◆ SMAC – The OUI field of the source MAC address. Enter the first three
octets (bytes) of the MAC address, or Any.
◆ DMAC Type – The type of destination MAC address. (Options: Any, BC
(Broadcast), MC (Multicast), UC (Unicast)
◆ Frame Type – The supported types are listed below:
■
Any – Allow all types of frames.
■
Ethernet – This option can only be used to filter Ethernet II
formatted packets. (Options: Any, Specific – 600-ffff hex;
Default: ffff)
Note that 800 (IPv4) and 86DD (IPv6) are excluded.
A detailed listing of Ethernet protocol types can be found in RFC
1060. A few of the more common types include 0800 (IP), 0806
(ARP), 8137 (IPX).
■
LLC – Link Logical Control includes the following settings:
■
SSAP Address – Source Service Access Point address.
(Options: Any, Specific (0x00-0xff); Default: 0xff)
■
DSAP Address – Destination Service Access Point address.
(Options: Any, Specific (0x00-0xff); Default: 0xff)
■
Control – Control field may contain command, response, or
sequence information depending on whether the LLC frame type
is Unnumbered, Supervisory, or Information. (Options: Any,
Specific (0x00-0xff); Default: 0xff)
■
SNAP – SubNetwork Access Protocol can be distinguished by an
OUI and a Protocol ID. (Options for PID: Any, Specific (0x00-0xffff);
Default: Any)
If the OUI is hexadecimal 000000, the protocol ID is the Ethernet
type (EtherType) field value for the protocol running on top of SNAP.
If the OUI is that of a particular organization, the protocol ID is a
value assigned by that organization to the protocol running on top
of SNAP.
In other words, if value of the OUI field is 00-00-00, then value of
the PID will be etherType (0x0600-0xffff), and if value of the OUI is
