Fiber Transceivers and 802.1q
By default, do multimode fiber transceivers pass tagged packets (802.1q)?
I see some transceivers listed as 802.1q transparent, and others as stating not at all.
I have run into Pheonix Contact transceivers, where dependent on the serial number, either could or could not pass 80.21q traffic.
I need to upgrade some Allied Telesyn transceivers because they are finicky about speed and duplex, and refuse to work with Cisco Catalyst trunk and access ports. I finally got them working with an gigabit HP ProCurve (but only on one node, where the other node needed to explicitly be a 10/100 switch so as to set the auto-negotiation to 100).
I will be upgrading to a gigabit transceiver, but need to be sure it supports 802.1q; I'm looking at http://www.startech.com/item-specs/ET91000SC-Gigabit-1000Mbps-RJ45-to-Multimode-SC-Fiber-Media-Converter.aspx right now.
If anyone has recommendations, I need the transceiver to be gigabit and utilize sc connectors for multimode fiber.
