Description
This article describes various commands to check NIC and interface drops.
Scope
FortiGate.
Solution
The following commands are to check the Network interface statistics and counters of received/transmitted packets and drops.
diagnose netlink interface list name <interface name>
Sample output:
diag netlink interface list name wan1
if=wan1 family=00 type=1 index=4 mtu=1500 link=0 master=0
ref=329 state=off start fw_flags=10000000 flags=up broadcast run allmulti multicast
Qdisc=mq hw_addr=90:6c:ac:5b:bf:b9 broadcast_addr=ff:ff:ff:ff:ff:ff
outbandwidth=92000(kbps)
:::Below output of priority only show when traffic shaping applied and bandwidth values specified.
priority=0 allocated-bandwidth=8(kbps) total_bytes=225378K drop_bytes=0
priority=1 allocated-bandwidth=0(kbps) total_bytes=2320057K drop_bytes=5278K
priority=2 allocated-bandwidth=0(kbps) total_bytes=0 drop_bytes=0
priority=3 allocated-bandwidth=379(kbps) total_bytes=826200K drop_bytes=29K
priority=4 allocated-bandwidth=91611(kbps) total_bytes=0 drop_bytes=0
stat: rxp=8542076 txp=7928261 rxb=5853285911 txb=3381014267 rxe=0 txe=0 rxd=0 txd=0 mc=0 collision=0
re: rxl=0 rxo=0 rxc=0 rxf=0 rxfi=0 rxm=0
te: txa=0 txc=0 txfi=0 txh=0 txw=0
misc rxc=0 txc=0
More details regarding the counters:
rxp = received packets
txp = transmitted packets
rxb = received bytes
txb = transmitted bytes
rxe = received errors
txe = transmitted errors
rxd and txd counters indicates the number of packets dropped on the interface
mc = multicast
collision indicate if there are collisions on the interface
re = received errors
te = transmitted errors
Other commands: config global:
diag hardware deviceinfo nic wan1

Or:
get hardware nic wan2
fnsysctl ifconfig <interface name> (internal command)
Repeat commands to check for increases in drops/collisions.
Alternatively, clear the counters through the following command and verify counters again.
diagnose netlink interface clear <interface name>
diag netlink interface clear wan1
Note:
Versions 5.0 up to 6.4 are out of engineering support. So these commands might be different on higher versions. Consider upgrading the firmware level on the device to a supported version (7.0 up to 7.6). Check here the firmware path and compatibility depending on the hardware:
