Question about EX90 PC port speed/duplex

[Nick Halbert-Lillyman]

Does anybody know if the EX90's PC port speed/duplex settings follow the settings for the primary port, or does it always stay at Auto?

Is there a way to manually set it?

As we utilise fibre in many locations, hard setting speed and duplex settings is unfortunately a neccesity in many cases.

The EX90 acts as a switch, so the two ports operate separately.  I cannot see a way via the interface to set the PC port settings and it stays as auto.  This port can negotiate a different speed than then LAN/primary port.

As long as the LAN/primary port has the right speed and duplex setting to connect to your network, the connection to the PC shouldn't be a problem.

Thanks Wayne.

Unfortunately, it's still a problem... we are running a fleet of thin clients over fibre SFP > media converter.  The thin client speed/duplex settings are assigned according to which subnet they sit in.  As 95% of our fleet plugs straight into the media converter, they are hard set to 100Mbps/full duplex.  Essentially this means that we need to set up a different subnet and VLAN, with different speed/duplex settings, for thin clients that sit behind an EX90.

It seems a bit silly that you could set speed/duplex on one port and not the other, especilly when the device is made by a networking company

You can probably change the setting on the NIC via a root login with the ethtool command, but not sure how you'd get that to stay there as a persistent setting (and it's not likely to be a "Supported" fix). 

Perhaps the best path for you would be to log the ability to enable this functionality as a Feature Request with your Cisco Account Manager and hope that R&D include it in a future firmware release.
