Measures reported by CtxNsIpv6Test

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.

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

The measures made by this test are as follows:

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

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

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

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

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

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

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

 

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

 

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

 

Frag_proc_reassembly Indicates the number of IPv6 fragments processed without reassembly. Number

 

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

 

Err_hdr_pkts 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 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_attacks 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.

Reassemble_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_frag_length_recvd 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.
