7840 Bandwidth Configuration

  • 1.  7840 Bandwidth Configuration

    Posted 04-14-2016 07:30 PM

    Is there anyone that can provide insight into the configuration of the tunnel/circuit on a 7840?

     

    I have 2 units deployed on a private 10G wavelength circuit.

     

    The units are up and running, with 1 / 2G (min / max) bandwidth configured. When I attempt to increase the min / max the tunnel shutsdown and the curciut wont ever leave 'In Prog' as its state.

     

    Any help appreciated.

    Hi agehring,

     

    you question is not clear in details, can you please post he config ?

     

    FYI, if i remember correct, a tunnel with more at 1Gbs is supported only in a Multi-Gigabit Circuit, additional a 10Gig License must be present.

    I have two 7840s, that are connected and running a current tunnel, e.g.;

      RTT (min/avg/max)    : 1 / 24 / 24 ms

     

    They are connected to 10G interfaces on my network switches and show running at 10G, e.g.;

     

         ge2           id    10G     Online      FCIP

     

    I have the WAN Rate Upgrade 1 license, installed 

     

    admin> licenseshow

    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:

        Advanced Extension license

    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:

        Extended Fabric license

        Trunking license

        Fabric Vision license

    XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:

        WAN Rate Upgrade 1 license

     

    when I attempt to increase the min/max bandwidht beyond the current 1000000 / 2000000 kbps, the tunnel drops, and the circuit goes into 'In Prog" status.

     

    I'm trying to get the min / max to 5000000 / 9500000 kbps

    How many Tunnel have you configured ?

     

    from Relase Notes:

     

    > WAN license provide for a troughput up to 5 Gbps

    > The total bandwidth aggregated for all tunnels should not exceed the limits established by the licenses.

    > WAN license provide for a troughput up to 5 Gbps

    > The total bandwidth aggregated for all tunnels should not exceed the limits established by the licenses.

     

    As noted, the WAN Rate Upgrade 1 license is installed:

     

    WAN Rate Upgrade 1

    Increases bandwidth available to all extension tunnels configured on the switch from 5 Gbps for the base hardware to 10 Gbps.

     

    I'll also note that a change to the current bandwidth, meaning above the current setting of 2G (max), fails - so even a change to 5G doesn't work.

     

    Only the one tunnel/circuit

    I think - but I'm not sure - the restrictions Note refer both WAN 1 and 2 License.

    but when you say, you only this one tunnel/circuit configured, you should have enough throughput so any License problem can be excluded.

     

    have you review FOS Release Notes if any such impact is caused due a Defective ?

    Running 7.4.1b.

     

    There was nothing in the release notes that appeared relevant to my environment...

     

    I would hope that there isn't a 'defect' that a swich designed to transfer FC traffic @ 40G, can't be configured to operate above 2G.

    Is anyone familiar with what the difference is between:

     

    portcfgge --set -wan

     

    portcfgge --set -lan

     

    ???

    gehring,

     

    just to understand, is this a FCIP Circuit ?

     

    I found a note, but is not specified if this restriction is only on 7800 or 7840

     

    >A single FCIP circuit cannot exceed 1 Gbps capacity

     

    if this is applicable to 7840, that would answer the question.

    Yes, this is a FCIP circuit.

     

    >A single FCIP circuit cannot exceed 1 Gbps capacity

     

    Considering that it's currently running a 2G, I'm guessing this doesn't apply to the 7840...

    have you tried anothe min / max commit rate ?

     

    instead

     

    >5000000 / 9500000 kbps

     

    try with

     

    min 4000000 / max 9000000

     

    keep in mind, both side must  have the same value, additional i would first stop the circuit before re-configure and then bring up

    I've tried with multiple combination varing from 1G - 10G, where the min was 4x, 2x or 1x of the max.

     

    The fastes combination I can get operational is 1/2. 2/2 fails, for instance

    If the tunnel/circuits fails there should be an event message outlining the issue why it dropped the link. If there are inconsistencies between the two end-points from a configuration perspective a circuit will not come up.

    Posted 04-20-2016 08:01 AM

    Perhaps I'm looking in the wrong place for the event message. Where would you look for it?

     

    A new note, as part of the troubleshooting:

     

    Setting the min/max to 2G/3G leaves the tunnel/circuit "up", but it fails to pass any traffic...

    I assume you have warranty and/or maintenance on these boxes. I would open a ticket with your vendor and capture a supportsave from both of them to have it looked at. There are a few areas where this can go wrong. It's simply too hard to speculate on this.

    Try running the wantool and test the circuit.
