Adding 2.5Gbps Ports to XG-7100-1U

Mael

I finally received the PCIe adaptor and was able to install the XIAOLO 2.5 I225V 2.5G card into the XG-7100 and move the WAN interface over to it. Everything is working great. The router sees the card and so far the connection has been solid. This upgrade, along with a new Netgear CM2050V modem with a 2.5Gb interface, has increased my download speeds from 940Mbps to 1414Mbps.

Thank You @stephenw10 for all your help!

The only odd thing I've noticed is the traffic graphs for the WAN interface no longer show up and this is what I see in the interfaces widget (I've cropped out my IP addresses.)

Here's what I see under Interfaces --> Status

And finally here's what I see from the command line (again removing my IP info)

ifconfig -vvm
igc0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

                media 10baseT/UTP

Any ideas how I can fix this, or is this just something I'll have to live with?

That is almost certainly because your WAN interface was previously using the switch port Eth1 and it's still referencing that. Interfaces using the switch ports use the switch port status since the internal ports are always up.
The easiest way to correct that is to edit the config and remove the line.
Your WAN interface config will look something like:

		<wan>
			<enable></enable>
			<if>igc0</if>
			<mtu></mtu>
			<ipaddr>dhcp</ipaddr>
			<ipaddrv6>dhcp6</ipaddrv6>
			<subnet></subnet>
			<gateway></gateway>
			<blockpriv></blockpriv>
			<blockbogons></blockbogons>
			<dhcphostname></dhcphostname>
			<media></media>
			<mediaopt></mediaopt>
			<dhcp6-duid></dhcp6-duid>
			<dhcp6-ia-pd-len>0</dhcp6-ia-pd-len>
			<switchif>switch0.port1</switchif>
		</wan>

Just remove the line: <switchif>switch0.port1</switchif> and reboot.

Or backup the config, remove the line and restore it without that.

@stephenw10 - Stupid question. What file should I edit? I tried poking around in /etc and didn't find it.

stephenw10

The main config file: /conf/config.xml

Exporting - editing and re-importing is generally safer though.

@stephenw10 - Thanks again. Editing the config fixed the problem.

Mael

@stephenw10 - Well one more problem seems to have cropped up. My OpenVPN is no longer connecting since I moved the WAN interface. I don't see any obvious error messages in the OpenVPN log. Any ideas?

stephenw10

Not really. Changing the WAN interface should make no difference. Is that the server end?

Mael

@stephenw10 - I was able to fix the problem by re-exporting my client certificate and loading it back into the OpenVPN client. Very weird.

@stephenw10 Sorry for quickening this necro-thread, but I wanted to share my success with some 10GBaseT SFP+ transceivers and my 7100, just in case someone else stumbled onto this thread looking for clues.

stephenw10

I assume they only work at 10G and 1G though? Or even only at 10G? I would not expect that to link at 2.5G.

Brad303

@stephenw10 Yes, of course you're right. I was thinking my Calix ONT was the GP110X with only 2.5GBaseT, but it's the GP1101X w/10GbE.
