9. If the matching field has this capability, enter the mask value. To select a single
value, set of the mask bit values to all ones.
10. Optionally, configure more matching rules for the current filter by repeating steps
3, 4, 5, 6, 7, 8 and 9 as many times as necessary.
6.2.1. MAC Selection
MAC frames are envelopes in which the Ethernet frames are sent and received. MAC
frame format is currently specified by the standard IEEE 802.3. This format is shared
by all existing Ethernet interfaces thus making Ethernet the most scalable transmission
technology currently available.
xGenius provides frame selection based on the MAC address source and destination
and Ethertype value. It is possible to configure a matching mask for all three fields to
select a value set rather than a single value.
Table 6.1: MAC Selection
Field Description
Source MAC address
match
Enables selection by source MAC address in the current fil-
ter. The value configured here is used to determine which
frames are allowed to pass through the filter and which ones
are blocked. The available configuration values for this field
are:
• Ignore: The source MAC address is ignored and not taken
into account for the purpose of the filter. No frame is
selected by the filter when Ignore has been configured.
• Equal to: All frames matching a user configurable pattern
are allowed to pass through the filter. The matching pattern
is configured with the help of the Source MAC address and
Source MAC address mask fields.
Source MAC address This is a 48-bit MAC address in the standard hexadecimal-
digit format XX:XX:XX:XX:XX:XX. Source addresses match-
ing some or all bits of the address configured here will be
allowed to pass through the filter. Bits used for matching
frames to this filter are configured in the Source MAC
address mask.
Source MAC address
mask
This is the mask for the source MAC address filter selection
rule. Before comparing the Source MAC address field with
the frame addresses, bit wise AND operations are carried out
between the value configured here and the Source MAC
address field so that only the values surviving the AND are
taken into account for matching the filter.
