How to see WAN interface speed

[Pedro_Espindola]

Hello everyone,

I am unable to see the speed of WAN interface in 1400 appliances. I tried this:

# clish -c 'show interface WAN'
Failed to find the requested interface

# ethtool WAN
Settings for WAN:
No data available

# cat /sys/class/net/WAN/speed
cat: read error: Invalid argument

SNMP using IF-MIB::ifspeed, returns 0.

All these commands work for DMZ, which is also set for internet.

How can I check the WAN interface speed?

Hi Pedro, 

if you run "show route" , you will see you exact interfaces as directly connected. There is written as WAN interface

But in the output of "show interfaces" command you will see you custom named interfaces. you can check ip addresses to specify which one is wan interface. Route table will show the original name. You can check also internet-connection interfaces name.

Hello Huseyin,

Thank you for your answer.

I tried that, but link-speed shows as empty:

# clish -c 'show interface SITELBRA' | grep -i speed
link-speed:

Then I tried:

# clish -c 'show internet-connections' | grep -i speed
port-speed: 115200
dmz-link-speed: 10/half
wan-link-speed: 10/half
link-speed: 10/half
port-speed: 115200
dmz-link-speed: 10/half
wan-link-speed: 10/half
link-speed: 10/half

But:

# ethtool DMZ | grep -i speed
Speed: 100Mb/s

# cat /sys/class/net/DMZ/speed
100

So why do I see dmz-link-speed: 10/half and Speed: 100Mb/s? 

I am sure it isn't negociated at 10Mbps because of high throughput in the DMZ interface. 100Mbps must be correct.

I am having issues with speed in the WAN interface, but if the "dmz-link-speed: 10/half" information is incorrect, how can I trust that the "wan-link-speed: 10/half" information is correct?

PS: I don't have access to the ISP router, so I can't check speed in it, but the model supports 1Gbps.

Thanks Dameon! That seems to be correct for 1470 and 1490.

For 1430 and 1450, "ethtool WAN" will work.
