The IP TOS field in a packet is defined as all eight bits of the Service Type
octet in the IP header. The 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
TOS Bits value that are used for comparison against the IP TOS field in a
packet.
The 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
TOS Mask denote the bit positions in the 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 a TOS Bits value of 0 and a TOS Mask of 00. This is an
optional configuration.
For IPv6 ACLs, configure these parameters:
• Protocol—Select the Protocol field to use an L3 or L4 protocol match
condition based on the value of the IP Protocol field in IPv4 packets or the
Next Header field of IPv6 packets.
If you select the 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 you select this checkbox, 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.
• Destination IPv6 Prefix Length—Enter the prefix length of the destination
IPv6 address.
