Frame Type: The supported Frame 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 RFC1060. 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 where decimal numbers between 0 and 255. When the mask is
converted to a 32-bit binary string and read from left to right, all bits
following the first zero must also be zero.
IP Fragment – Indicates whether or not fragmented packets are accepted.
(Options: Any, Yes, No; Default: Any)DatagrAPS may be fragmented to
ensure they can pass through a network device which uses a maximum
transfer unit smaller than the original packet's size.
