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
other than 00-00-00, then valid value of the PID will be any value
from 0x0000 to 0xffff.
IPv4 – IPv4 frame type includes the following settings:
■
Protocol – IP protocol number. (Options: Any, UDP, TCP, or
■
Other (0-255))
Source IP – Source IP address. (Options: Any, Specific)
■
To configure a specific source IP address, enter both the address
and mask format. The address and mask must be in the format
x.y.z.w where x, y, z, and w are decimal numbers between 0
