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?
