Enter a packet's destination layer 4 port match condition for the selected extended
IP ACL rule. This field identifies the first port of the port range and has a value from
0 to 65535. The value of the start port must be less than or equal to the end port.
The start port, end port, and all ports in between will be part of the contiguous
source port range. This is an optional configuration.
Enter a packet's destination layer 4 port match condition for the selected extended
IP ACL rule. This field identifies the last port of the port range and has a value from
0 to 65535. The value of the end port must be greater than or equal to the start
port. The start port, end port, and all ports in between will be part of the contiguous
source port range. This is an optional configuration.
Click the drop-down menu to select a Service Type match condition for the
extended IP ACL rule from the pull-down menu. The possible values are IP DSCP,
IP precedence, and IP TOS, which are alternative ways of specifying a match crite-
rion for the same Service Type field in the IP header, however each uses a different
user notation. After a selection is made the appropriate value can be specified.
IP DSCP Configuration

Specify the IP DiffServ Code Point (DSCP) field. The DSCP is defined as the
high- order six bits of the Service Type octet in the IP header. This is an
optional configuration. Enter an integer from 0 to 63. The IP DSCP is selected
by possibly selection one of the DSCP keyword from a drop-down box. If a
value is to be selected by specifying its numeric value, then select the 'Other'
option in the drop-down box and a text box will appear where the numeric value
of the DSCP can be entered.
IP Precedence Configuration

The IP Precedence field in a packet is defined as the high- order three bits of
the Service Type octet in the IP header. This is an optional configuration. Enter
an integer from 0 to 7.
IP TOS Configuration

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 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 compari-
son 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 a0 and a TOS Mask of 00. This is an optional configuration.
Click Configure to setup the corresponding match criteria for the selected rule.
Click Delete to remove the currently selected Rule from the selected ACL. These
changes will not be retained across a power cycle unless a save configuration is
performed.
Click Submit to update the switch with the values on the screen. If you want the
switch to retain the new values across a power cycle you must perform a save.
This button is shown when you are configuring individual match conditions.
Click Cancel to discard the changes made on the page.
