Section 8 - Conguring Client Quality of Service (QoS)
Field Description
IP Precedence Select this option and enter a value to use the packet’s IP Precedence value in the IP
header as match criteria. You can select only one service type (DSCP, IP Precedence or
TOS bits) to use for match criteria.
The IP Precedence range is 0 – 7.
IP TOS Bits Select this option and enter a value to use the packet’s Type of Service bits in the IP header
as match criteria. You can select only one service type (DSCP, IP Precedence or TOS bits)
to use for match criteria.
The IP TOS eld in a packet is dened 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 eld in a packet.
The TOS Mask value is a two-digit hexadecimal number from 00 to ff, representing an
inverted (i.e. 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 eld 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 signicant, use a TOS Bits value of a0 and a TOS Mask of 00. This is an optional
conguration.
IPv6 ACL
Protocol Select the Protocol eld to use an L3 or L4 protocol match condition based on the value of
the IP Protocol eld in IPv4 packets or the Next Header eld of IPv6 packets.
Once you select the eld, choose the protocol to match by keyword or enter a protocol ID.
Select From List
Select one of the following protocols from the list:
•) IP
•) ICMP
•) IPv6
•) ICMPv6
•) IGMP
•) TCP
•) UDP
Match to Value
To match a protocol that is not listed by name, enter the protocol ID.
The protocol ID is a standard value assigned by the IANA. The range is a number from
0–255.
Source IPv6
Address
Select this eld to require a packet’s source IPv6 address to match the address listed here.
Enter an IPv6 address in the appropriate eld to apply this criteria.
Source IPv6 Prex
Length
Enter the prex length of the source IPv6 address.
