- Select From List—DSCP Assured Forwarding (AS), Class of Service (CS), or
Expedited Forwarding (EF) values.
- 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.
• Destination IPv6 Address—Select this field to require a packet's destination IPv6
address to match the address listed here. Enter an IPv6 address in the appropriate field
to apply this criteria.
