IPv6 Test

A Citrix ADC appliance supports both server-side and client-side IPv6 and can therefore function as an IPv6 node. It can accept connections from IPv6 nodes (both hosts and routers) and from IPv4 nodes, and can perform Protocol Translation (RFC 2765) before sending traffic to the services.

This test monitors the IP (Internet Protocol) v6 traffic on the NetScaler appliance, measures the current IPv6 load on the NetScaler device, and promptly captures IP-related anomalies.

Target of the test : A Citrix ADC VPX/MPX

Agent deploying the test : A remote agent

Outputs of the test : One set of results for the Citrix ADC VPX/MPX appliance being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which the test is being configured.

NetScaler Username, NetScaler Password, and Confirm Password

To monitor a NetScaler device, the eG agent should be configured with the credentials of a user with read-only privileges to the target NetScaler device. Specify the credentials of such a user in the NetScaler Username and NetScaler Password text boxes. Then, confirm the password by retyping it in the Confirm Password text box.

SSL

The eG agent collects performance metrics by invoking NITRO (NetScaler Interface Through Restful interfaces and Objects) APIs on the target NetScaler device. Typically, the NITRO APIs can be invoked through the HTTP or the HTTPS mode. By default, the eG agent invokes the NITRO APIs using the HTTPS mode. This is why, the SSL flag is set to Yes by default. If the target NetScaler device is not SSL-enabled, then the NITRO APIs can be accessed through the HTTP mode only. In this case, set the SSL flag to No.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Data received

Indicates the IPv6 data received during the last measurement period.

MB

These measures are good indicators of the current IPv6 workload on the appliance.

 

 

 

Data transmitted

Indicates the IPv6 data transmitted during the last measurement period.

MB

Packets received

Indicates the number of IPv6 packets received during the last measurement period.

Number

Packets transmitted

Indicates the number IPv6 packets transmitted during the last measurement period.

Number

Total routed packets

Indicates the number of IPv6 routed packets received during the last measurement period.

Number

 

Total routed mbits

Indicates the number of IPv6 routed packets received during the last measurement period.

Number

 

Fragments received

Indicates the number IPv6 fragment packets received during the last measurement period.

Number

 

TCP fragments reassembled

Indicates the number of TCP fragments processed after reassembly during the last measurement period.

Number

 

UDP fragments reassembled

Indicates the number of Indicates the number of TCP fragments processed after reassembly during the last measurement period.

Number

 

Fragments processed reassembly

Indicates the number of IPv6 fragments processed without reassembly.

Number

 

Fragments forwarded to the client or server

Indicates the number of IPv6 fragments forwarded to the client or server without reassembly during the last measurement period.

Number

 

Error header packets

Indicates the number of packets received during the last measurement period that contain an error in one or more components of the IPv6 header.

Number

Ideally, the value of this measure should be 0.

Unsupported header packets

Indicates the number of packets received during the last measurement period that contain an unsupported next header.

Number

The supported next headers are TCP, ICMP, UDP, OSPF, and FRAGMENT. Any next header outside of this list therefore is unsupported.

Ideally, the value of this measure should be 0.

Land attack packets

Indicates the number of land-attack packets received during the last measurement period.

Number

Land-attack packets are those where both the source and destination addresses are the same. If not dropped, these packets can lock up the appliance.

Reassembled data too big

Indicates the number of the packets received during the last measurement period for which the reassembled data exceeds the Ethernet packet data length of 1500 bytes.

Number

Ideally, the value of this measure should be 0.

Zero fragment length received

Indicates the number of packets received during the last measurement period with a fragment length of 0 bytes.

Number

Ideally, the value of this measure should be 0.
