On X460G2 model (with EXOS 184.108.40.206 or EXOS 220.127.116.11) we noticed a misunderstood behaviour with "intel" comptuers connected on Etremexe ports configured in auto-sense mode with speed and duplex settings ( instead off "auto on" only).
For instance, if on Extreme side we configure the port 3 like :" configure ports 3 auto on speed 1000 duplex full on"
And we configure a computer with its network interface configured in auto-sense mode.
After, we are waiting 1 minute and then we connect the computer on port 3 ; we noticed that port 3 stay in "ready state" on Extreme side and port remains down on computer side. (no connectivity)
If we desactivate and activate the network interface on the computer (while it remains connected to the swith) the port comes up in 1Gbps Full duplex .
To sum up ; what are the use cases of " configure auto on speed 1000 duplex Full" port configuration?
And what kind of behaviour is expected?
(it' doesn't seems to advertise the speed to improve the negotiation)
There is no problem with the "auto on" mode, or auto off with speed and duplex whan we want to hard set the network configuration.
configure port NUMBER auto on speed 1000 duplex fullcommand restricts the advertised link modes to a speed of 1Gbps and full duplex operation.
auto on", all supported link modes are advertised, as shown in the output of
Link partner advertised link modes: 10baseT/Half 10baseT/Full
auto on speed 1000 duplex full" this is reduced to just one link mode:
Link partner advertised link modes: 1000baseT/Full
auto on, but to no link with
auto on speed 1000 duplex full, something is not OK.
show port configurationyou can see the result of successful auto-negotiation on the EXOS switch. Did you verify that the result with just
auto onis full duplex?
auto on speed 1000 duplex full) have been reproduced with laptops using Intel I219 network cards (On W10 OS) , with sub-interfaces with vlan tagging.
auto on speed 1000 duplex fullwas used to be sure to negotiate 1Gbps speed....
