Hardware acceleration get and diagnose commands

This section describes some get and diagnose commands you can use to display useful information about the NP6 processors sessions processed by NP6 processors.

get hardware npu np6

You can use the get hardware npu np6 command to display information about the NP6 processors in your FortiGate and the sessions they are processing. This command contains a subset of the options available from the diagnose npu np6 command. The command syntax is:

get hardware npu np6 {dce <np6-id> | ipsec-stats | port-list | session-stats <np6-id> | sse-stats <np6-id> | synproxy-stats}

 

<np6-id> identifies the NP6 processor. 0 is np6_0, 1 is np6_1 and so on.

dce show NP6 non-zero sub-engine drop counters for the selected NP6.

ipsec-stats show overall NP6 IPsec offloading statistics.

port-list show the mapping between the FortiGate's physical ports and its NP6 processors.

session-stats show NP6 session offloading statistics counters for the selected NP6.

sse-stats show hardware session statistics counters.

synproxy-stats show overall NP6 synproxy statistics for TCP connections identified as being syn proxy DoS attacks.

diagnose npu np6

The diagnose npu np6 command displays extensive information about NP6 processors and the sessions that they are processing. Some of the information displayed can be useful for understanding the NP6 configuration, seeing how sessions are being processed and diagnosing problems. Some of the commands may only be useful for Fortinet software developers. The command syntax is:

diagnose npu np6 {options}

The following options are available:

fastpath {disable | enable} <np6-od> enable or disable fastpath processing for a selected NP6.

dce shows NP6 non-zero sub-engine drop counters for the selected NP6.

dce-all show all subengine drop counters.

anomaly-drop show non-zero L3/L4 anomaly check drop counters.

anomaly-drop-all show all L3/L4 anomaly check drop counters.

hrx-drop show non-zero host interface drop counters.

hrx-drop-all show all host interface drop counters.

session-stats show session offloading statistics counters.

session-stats-clear clear sesssion offloading statistics counters.

sse-stats show hardware session statistics counters.

sse-stats-clear show hardware session statistics counters.

pdq show packet buffer queue counters.

xgmac-stats show XGMAC MIBs counters.

xgmac-stats-clear clear XGMAC MIBS counters.

port-list show port list.

ipsec-stats show IPsec offloading statistics.

ipsec-stats-clear clear IPsec offloading statistics.

eeprom-read read NP6 EEPROM.

npu-feature show NPU feature and status.

register show NP6 registers.

fortilink configure fortilink.

synproxy-stats show synproxy statistics.

Using diagnose npu np6 npu-feature to verify enabled NP6 features

You can use the diagnose npu np6 npu-feature command to see what NP6 features are enabled and which are not. The following command output shows the normal default NP6 configuration for most FortiGates. In this output all features are enabled except low latency features and GRE offloading. Low latency is only available on the FortiGate-3700D and DX models and GRE offloading will become available in a future FortiOS release. The following output is from a FortiGate-1500D

If you use the following command to disable fastpath for np_0:

config system np6

edit np6_0

set fastpath disable

end

The npu-feature command output show this configuration change:

Using the diagnose sys session/session6 list command

The diagnose sys session list and diagnose sys session6 list commands list all of the current IPv4 or IPv6 sessions being processed by the FortiGate. For each session the command output includes an npu info line that displays NPx offloading information for the session. If a session is not offloaded the command output includes a no_ofld_reason line that indicates why the session was not offloaded.

Displaying NP6 offloading information for a session

The npu info line of the diagnose sys session list command includes information about the offloaded session that indicates the type of processor and whether its IPsec or regular traffic:

  • offload=1/1 for NP1(FA1) sessions.
  • offload=2/2 for NP1(FA2) sessions.
  • offload=3/3 for NP2 sessions.
  • offload=4/4 for NP4 sessions.
  • offload=5/5 for XLR sessions.
  • offload=6/6 for Nplite/NP4lite sessions.
  • offload=7/7 for XLP sessions.
  • offload=8/8 for NP6 sessions.
  • flag 0x81 means regular traffic.
  • flag 0x82 means IPsec traffic.

Example offloaded IPv4 NP6 session

The following session output by the diagnose sys session list command shows an offloaded session. The information in the npu info line shows this is a regular session (flag=0x81/0x81) that is offloaded by an NP6 processor (offload=8/8).

diagnose npu np6 session-stats <np6-id> (number of NP6 IPv4 and IPv6 sessions)

You can use the diagnose npu np6 portlist command to list the NP6-ids and the interfaces that each NP6 is connected to. The <np6-id> of np6_0 is 0, the <np6-id> of np6_1 is 1 and so on. The diagnose npu np6 session-stats <np6-id> command output incudes the following headings:

  • ins44 installed IPv4 sessions
  • ins46 installed NAT46 sessions
  • del4 deleted IPv4 and NAT46 sessions
  • ins64 installed NAT64 sessions
  • ins66 installed IPv6 sessions
  • del6 deleted IPv6 and NAT64 sessions
  • e is the error counter for each session type

diagnose sys mcast-session/session6 list (IPv4 and IPv6 multicast sessions)

This command lists all IPv4 or IPv6 multicast sessions. If a multicast session can be offloaded, the output includes the offloadable tag. If the multicast path can be offloaded one of the paths in the command output is tagged as offloaded.

The only way to determine the number of offloaded multicast sessions is to use the diagnose sys mcast-session/session6 list command and count the number of sessions with the offload tag.

diagnose npu np6 sse-stats <np6-id> (number of NP6 sessions and dropped sessions)

This command displays the total number of inserted, deleted and purged sessions processed by a selected NP6 processor. The number of dropped sessions of each type cam be determined by subtracting the number of successfull sessions from the total number of sessions. For example, the total number of dropped insert sessions is insert-total - insert-success.
