SD-WAN related diagnose commands

This topic lists the SD-WAN related diagnose commands and related output.

To check SD-WAN health-check status:

FGT # diagnose sys sdwan health-check
Health Check(server):
Seq(1 R150): state(alive), packet-loss(0.000%) latency(0.110), jitter(0.024) sla_map=0x0
Seq(2 R160): state(alive), packet-loss(0.000%) latency(0.068), jitter(0.009) sla_map=0x0

FGT # diagnose sys sdwan health-check
Health Check(ping):
Seq(1 R150): state(alive), packet-loss(0.000%) latency(0.100), jitter(0.017) sla_map=0x0
Seq(2 R160): state(dead), packet-loss(100.000%) sla_map=0x0

FGT # diagnose sys sdwan health-check google
Health Check(google):
Seq(1 R150): state(alive), packet-loss(0.000%) latency(0.081), jitter(0.019) sla_map=0x0
Seq(2 R160): state(alive), packet-loss(0.000%) latency(0.060), jitter(0.004) sla_map=0x0

To check SD-WAN member status:

• When SD-WAN load-balance mode is source-ip-based/source-dest-ip-based.

  FGT # diagnose sys sdwan member
  Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 0
  Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 0
  

• When SD-WAN load-balance mode is weight-based.

  FGT # diagnose sys sdwan member
  Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 33
    Session count: 15
  Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 66
    Session count: 1
  

• When SD-WAN load-balance mode is measured-volume-based.
  • Both members are under volume and still have room:

    FGT # diagnose sys sdwan member
    Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 33
      Config volume ratio: 33, last reading: 218067B, volume room 33MB
    Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 66
      Config volume ratio: 66, last reading: 202317B, volume room 66MB
    

  • Some members are overloaded and some still have room:

    FGT # diagnose sys sdwan member
    Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 0
      Config volume ratio: 33, last reading: 1287767633B, overload volume 517MB
    Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 63
      Config volume ratio: 66, last reading: 1686997898B, volume room 63MB
    

• When SD-WAN load balance mode is usage-based/spillover.
  • When no spillover occurs:

    FGT # diagnose sys sdwan member
    Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 255
      Egress-spillover-threshold: 400kbit/s, ingress-spillover-threshold: 300kbit/s
      Egress-overbps=0, ingress-overbps=0
    Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 254
      Egress-spillover-threshold: 0kbit/s, ingress-spillover-threshold: 0kbit/s
      Egress-overbps=0, ingress-overbps=0
    

  • When member has reached limit and spillover occurs:

    FGT # diagnose sys sdwan member
    Member(1): interface: R150, gateway: 10.100.1.1 2000:10:100:1::1, priority: 0 1024, weight: 255
      Egress-spillover-threshold: 400kbit/s, ingress-spillover-threshold: 300kbit/s
      Egress-overbps=1, ingress-overbps=0
    Member(2): interface: R160, gateway: 10.100.1.5 2000:10:100:1::5, priority: 0 1024, weight: 254
      Egress-spillover-threshold: 0kbit/s, ingress-spillover-threshold: 0kbit/s
      Egress-overbps=0, ingress-overbps=0
    

  • You can also use the diagnose netlink dstmac list command to check if you are over the limit.

    FGT # diagnose netlink dstmac list R150
    dev=R150 mac=00:00:00:00:00:00 vwl rx_tcp_mss=0 tx_tcp_mss=0 egress_overspill_threshold=50000 egress_bytes=100982 egress_over_bps=1 ingress_overspill_threshold=37500 ingress_bytes=40 ingress_over_bps=0 sampler_rate=0 vwl_zone_id=1 intf_qua=0

To check the dynamic tunnel status:

# diagnose sys link-monitor interface <name> <name>_0

For example:

# diagnose sys link-monitor interface vd2-2
Interface(vd2-2): state(up, since Tue Jun 15 12:31:28 2021), bandwidth(up:1299bps, down:0bps), session count(IPv4:2, IPv6:0), tx(2409919 bytes), rx(5292290 bytes), latency(0.03), jitter(0.00), packet-loss(0.00).

# diagnose sys link-monitor interface vd2-2 vd2-2_0
Interface(vd2-2_0): state(up, since Tue Jun 15 15:21:52 2021), bandwidth(up:640bps, down:0bps), session count(IPv4:0, IPv6:0), tx(102242 bytes), rx(16388 bytes), latency(0.03), jitter(0.00), packet-loss(0.00).
