•
Ethernet Type
. Select an EtherType keyword or enter an EtherType value to add a
match condition based on the EtherType value.
•
Source MAC
. Requires a packet’s source MAC address to match the address
specified here.
•
Source MAC Mask
. Indicates which bits in the source MAC address are significant
and which are ignored. An F indicates that the bit is significant, while a 0 indicates
that the bit is ignored. For example, a MAC mask of FF:FF:FF:FF:FF:FF indicates that
all bits in the source MAC address are used as match criteria.
•
Destination MAC
. Requires a packet’s destination MAC address to match the
address specified here.
•
Destination MAC Mask
. Indicates which bits in the destination MAC address are
significant and which are ignored. An F indicates that the bit is significant, while a 0
indicates that the bit is ignored. For example, a MAC mask of FF:FF:FF:FF:FF:FF
indicates that all bits in the destination MAC address are used as match criteria.
•
Protocol Type
. Select a layer 4 protocol to use for the match criteria in the packet or
select
Other
and enter the value to match in the Protocol field of the IP packet.
•
Source IP Address
. Requires a packet’s source port IP address to match the
address listed here. In the IP Address field, enter a valid source IP address in dotted
decimal format.
•
Source Mask
. Enter a valid subnet mask to determine which bits in the IP address
are significant. Note that this is not a wildcard mask.
•
Source L4 Port
. Requires a packet’s TCP/UDP source port to match the port you
select. Select the desired L4 keyword from the list on which the rule can be based. If
you select Other, the screen refreshes and a Port ID field appears. Enter a
user-defined Port ID by which packets are matched to the rule.
•
Destination IP Address.
Requires a packet’s destination port IP address to match
the address listed here. In the IP Address field, enter a valid destination IP address in
dotted decimal format.
•
Destination Mask
. Enter a valid subnet mask to determine which bits in the IP
address are significant. This is not a wildcard mask.
•
Destination L4 Por

port you select. Select the desired L4 keyword from the list on which the rule can be
based. If you select Other, the screen refreshes and a Port ID field appears. Enter a
user-defined Port ID by which packets are matched to the rule.
•
IP DSCP
. Matches the packet’s DSCP to the class criteria’s when selected. Select the
DSCP type from the menu or enter a DSCP value to match. If you select Other, enter

•
IP Precedence
. Matches the packet’s IP Precedence value to the class criteria’s
when Enter a value in the range of 0–7.
•
IP ToS
. Matches the packet’s Type of Service bits in the IP header to the class
criteria’s when selected and a value is entered. In the ToS Bits field, enter a two-digit
hexadecimal number to match the bits in a packet’s ToS field. In the ToS Mask field,
specify the bit positions that are used for comparison against the IP ToS field in a
packet.
