GS748T Smart Switch
• Source Prefix/Prefix Length: Specify IPv6 Prefix combined with IPv6 Prefix length of
the network or host from which the packet is being sent. Prefix length can be in the
range (0 to 128).
• Source L4 Port: Specify a packet's source layer 4 port as a match condition for the
selected IPv6 ACL rule. Source port information is optional. Source port information
can be specified in two ways:
• Select keyword “other” from the drop-down menu and specify the number of the
port in the range from 0 to 65535.
• Select one of the keyword from the list: DOMAIN, ECHO, FTP, FTPDATA, HTTP,
SMTP, SNMP, TELNET, TFTP, and WWW. Each of these values translates into its
equivalent port number, which is used as both the start and end of the port range.
• Destination Prefix/Prefix Length: Enter up to 128-bit prefix combined with prefix
length to be compared to a packet's destination IP Address as a match criteria for the
selected IPv6 ACL rule. Prefix length can be in the range (0 to 128).
• Destination L4 Port: Specify a packet's destination layer 4 port as a match condition
for the selected IPv6 ACL rule. Destination port information is optional. Destination
port information can be specified in two ways:
• Select keyword “other” from the drop-down menu and specify the number of the
port in the range from 0 to 65535.
• Select one of the keyword from the list: DOMAIN, ECHO, FTP, FTPDATA, HTTP,
SMTP, SNMP, TELNET, TFTP, and WWW. Each of these values translates into its
equivalent port number, which is used as both the start and end of the port range.
• Flow Label: Flow label is 20-bit number that is unique to an IPv6 packet, used by end
stations to signify quality-of-service handling in routers. Flow label can be specified
within the range (0 to 1048575).
• IPv6 DSCP Service: 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 IPv6 header. This is
an optional configuration. Enter an integer from 0 to 63. The IPv6 DSCP is selected
by possibly selection one of the DSCP keyword from a drop-down menu. If a value is
to be selected by specifying its numeric value, then select the Other option in the
drop-down menu and a text box will appear where the numeric value of the DSCP can
be entered.
3. Click Cancel to cancel the configuration on the screen and reset the data on the screen to
the latest value of the switch.
4. To add the new rule to the ACL, click Apply.
5. To delete a rule from an ACL, select the check box associated with the rule and click Delete.
