ns simpleacl6¶
The following operations can be performed on "ns simpleacl6":
add | clear | flush | rm | show | stat
add ns simpleacl6¶
Adds a simple ACL6 rule to the NetScaler appliance. Simple ACL6 rules filter IPv6 packets on the basis of their source IP addresses and, optionally, the destination port and/or protocol. Any packet with the characteristics specified in the simple ACL6 rule is dropped.
Synopsys¶
add ns simpleacl6 <aclname> [-td <positive_integer>] <aclaction> -srcIPv6 <ipv6_addr|null> [-destPort <port> -protocol ( TCP | UDP )] [-TTL <positive_integer>]
Arguments¶
aclname
Name for the simple ACL6 rule. Must begin with an ASCII alphabetic or underscore (_) character, and must contain only ASCII alphanumeric, underscore, hash (#), period (.), space, colon (:), at (@), equals (=), and hyphen (-) characters. Cannot be changed after the simple ACL6 rule is created.
td
Integer value that uniquely identifies the traffic domain in which you want to configure the entity. If you do not specify an ID, the entity becomes part of the default traffic domain, which has an ID of 0.
Minimum value: 0
Maximum value: 4094
aclaction
Drop incoming IPv6 packets that match the simple ACL6 rule.
Possible values: DENY
srcIPv6
IP address to match against the source IP address of an incoming IPv6 packet.
destPort
Port number to match against the destination port number of an incoming IPv6 packet.
Omitting the port number creates an all-ports simple ACL6 rule, which matches any port. In that case, you cannot create another simple ACL6 rule specifying a specific port and the same source IPv6 address.
protocol
Protocol to match against the protocol of an incoming IPv6 packet. You must set this parameter if you set the Destination Port parameter.
Possible values: TCP, UDP
TTL
Number of seconds, in multiples of four, after which the simple ACL6 rule expires. If you do not want the simple ACL6 rule to expire, do not specify a TTL value.
Minimum value: 4
Maximum value: 2147483647
Example¶
add simpleacl6 rule1 DENY -srcIP6 fe80::2c0:95ff:fec5:d9b8 -destPort 80 -protocol TCPadd simpleacl rule2 DENY -srcIP6 3ffe:100:100::1 -TTL 600
clear ns simpleacl6¶
Removes all simple ACL6 rules from the NetScaler appliance.
Synopsys¶
clear ns simpleacl6
Example¶
clear ns simpleacl6
flush ns simpleacl6¶
Terminates all established IPv6 connections that match any of the newly configured simple ACL6 rules.Note: If you plan to create more than one simple ACL6 rule and flush existing connections that match any of them, you can minimize the affect on performance by first creating all of the simple ACL6 rules and then running flush only once.
Synopsys¶
flush ns simpleacl6 -estSessions
Arguments¶
estSessions
rm ns simpleacl6¶
Removes a simple ACL6 rule from the NetScaler appliance.
Synopsys¶
rm ns simpleacl6 <aclname> ...
Arguments¶
aclname
Name of the simple ACL6 rule that you want to remove.
Example¶
rm ns simpleacl6 rule1
Related Commands¶
show ns simpleacl6¶
Displays settings of all the simple ACL6 rules or of the specified simple ACL6 rule. To display settings of all the simple ACL6 rules, run the command without any parameters. To display settings of a particular simple ACL6 rule, specify the name of the simple ACL6 rule.
Synopsys¶
show ns simpleacl6 [<aclname>]
Arguments¶
aclname
Name of the simple ACL6 rule whose settings you want the NetScaler appliance to display.
Outputs¶
aclaction
Action associated with the SACL6 rule.
td
Integer value that uniquely identifies the traffic domain in which you want to configure the entity. If you do not specify an ID, the entity becomes part of the default traffic domain, which has an ID of 0.
srcIPv6
Source IP6 address.
stateflag
SACL6 state flag.
destPort
Destination Port.
protocol
Protocol associated with the ACL rule.
TTL
Time to expire this ACL rule(in seconds).
hits
Number of hits for this SACL6 rule.
time
Time when this acl is added.
devno
count
Example¶
show simpleacl6 rule1 Name: rule1 Action: DENY Hits: 5 srcIP6 = 3ffe:100:100::1 Protocol = TCP DestPort = 110 TTL: 200(seconds)
stat ns simpleacl6¶
Displays statistics related to the simple ACL6 rules.
Synopsys¶
stat ns simpleacl6 [-detail] [-fullValues] [-ntimes <positive_integer>] [-logFile <input_filename>] [-clearstats ( basic | full )]
Arguments¶
detail
Specifies detailed output (including more statistics). The output can be quite voluminous. Without this argument, the output will show only a summary.
fullValues
Specifies that numbers and strings should be displayed in their full form. Without this option, long strings are shortened and large numbers are abbreviated
ntimes
The number of times, in intervals of seven seconds, the statistics should be displayed.
Default value: 1
Minimum value: 0
logFile
The name of the log file to be used as input.
clearstats
Clear the statsistics / counters
Possible values: basic, full
Outputs¶
SimpleACL6 hits (SACL6Hits)
Packets matching a SimpleACL6.
SimpleACL6 misses (SACL6Miss)
Packets not matching any SimpleACL6.
SimpleACLs6 count (SACL6sCount)
Number of SimpleACL6s configured.
Allow SimpleACL6 hits (SACL6Allow)
Total packets that matched a SimpleACL6 with action ALLOW and got consumed by NetScaler.
Bridge SimpleACL6 hits (SACL6Bdg)
Total packets that matched a SimpleACL6 with action BRIDGE and got bridged by NetScaler.
Deny SimpleACL6 hits (SACL6Deny)
Packets dropped because they match SimpleACL6 with processing mode set to DENY.
Example¶
stat simpleacl6
