Want to use XG's to route between offices that currently have a dedicated Ethernet line but worried about QoS?

AllanD

We currently have three offices, our HQ with a XG310 and two sub offices with a XG125 each.  Each office has its own internet and we are using Cisco 1921 routers with a private ethernet line (50 Mbps) between them.  The layout looks something like this:

 

 

The Cisco routers, while they have served us well, are End of Life and the replacements are stupidly expensive for what we want to do.  The private Ethernet is currently 50 Mbps but we are looking to boost that to 100 Mbps soon.  Phone system traffic (VoIP) and video conferencing go over these lines and one of the things the Ciscos are good at is QoS.  We have never had a QoS issue between offices for phones or video even when the line is fully saturated.

I'm fairly confident I can dedicate two ports on the XG310 and one port on each branch office to route over the private line and eliminate the Cisco boxes.  But I am worried about QoS issues.  Are there settings for this or how would I go about configuring this?  Also would I call these interfaces "LAN" ports and just give them routable addresses between the buildings (192.168.255.1 and .2 for one pair, 254.1 and 2 for the other?) or do I make a fake "zone" for them?  Does it matter?

    Hi,

    QOS on the XG only works on the incoming.

    You would not normally use routing, but firewall rules because they give you greater control.

    I would suggest that you use the LAN zone for the new interfaces.

    So are you saying there is no way to apply QoS to a route between the devices and therefor you need a firewall rule so you can use Traffic Shaping?

     

    Would the source and destination both be LAN and the networks be defined between the two for the firewall rule to work?

     

    Seems clunky if that's the case but again I don't want to shell out $6k on replacement routers if the XG can do what I want.

    Hi Allan,

    I have been exploring my XG and as far as I can see you cannot apply QOS to routes. I appear to be wrong in my statement about QOS and outgoing looking at the traffic shipping policy tab. The re have been posts in the past where questions about QOS on outgoing have been raised. 

    The source and destination would be LAN zone, but your networks would be the defined in each rule. I prefer a rule for each site because debugging is easier, but you can have one rule for both sites outgoing from the HO and another rule incoming from each remote site on the HO XG. You apply your QOS settings in the firewall rules, there are 3 types of QOS you can configure if you so desire.

    Do the users at each branch office require access to the other branch office? If so you will need firewall rules for that as well.

    Yes, each office needs the other offices.  And actually the other offices are already defined in each XG.

     

    I might give it a trail run some weekend and see how things go.
