- Match to Value—A custom DSCP value, from 0 to 63.
• IP Precedence—Matches packets based on their IP Precedence value. If
selected, enter an IP Precedence value from 0 to 7.
• IP TOS Bits—Specifies a value to use the packet's Type of Service bits in
the IP header as match criteria.
The IP TOS field in a packet is defined as all eight bits of the Service Type
octet in the IP header. The IP TOS Bits value is a two-digit hexadecimal
number from 00 to ff.
The high-order three bits represent the IP precedence value. The high-order
six bits represent the IP Differentiated Services Code Point (DSCP) value.
• IP TOS Mask—Enter an IP TOS Mask value to identify the bit positions in the
IP TOS Bits value that are used for comparison against the IP TOS field in a
packet.
The IP TOS Mask value is a two-digit hexadecimal number from 00 to FF,
representing an inverted (that is, wildcard) mask. The zero-valued bits in the
IP TOS Mask denote the bit positions in the IP TOS Bits value that are used
for comparison against the IP TOS field of a packet. For example, to check
for an IP TOS value having bits 7 and 5 set and bit 1 clear, where bit 7 is most
significant, use an IP TOS Bits value of 0 and an IP TOS Mask of 00.
For IPv6 ACLs, configure these parameters:
• Protocol—Select the Protocol field to use a Layer 3 or Layer 4 protocol
match condition based on the value of the IP Protocol field in IPv4 packets or
the Next Header field in IPv6 packets.
If you select this field, choose the protocol to match by keyword or protocol
ID.
• Source IPv6 Address—Select this field to require a packet's source IPv6
address to match the address listed here. Enter an IPv6 address in the
appropriate field to apply this criteria.
• Source IPv6 Prefix Length—Enter the prefix length of the source IPv6
address.
• Source Port—Select this option to include a source port in the match
condition for the rule. The source port is identified in the datagram header. If
selected, choose the port name or enter the port number.
