mdf: It seems to take a while (~10-15 seconds) for my ERL to assign a dhcp lease from clients first connecting. Is that normal or have I done something?

 

Nope that isn't normal - but, it is easy to fix:

 

configure
set service dhcp-server shared-network-name LAN authoritative enable
commit
save

Where LAN is your DHCP pool name.

 

 

Ta, that did the trick.

 

I've got two DHCP servers, one main and one for a guest network. Should I run this for both DHCP pool names, or is that stupid (you don't have two "authoritative" sources)?

Amateur hour question here.
I have just done a move from bigpipe to 2Degrees and was wondering about settings changes. I have updated the user and password details on eth0. Is there a simple way to do the addition of vlan10? I’ve considered a reboot and redoing the wizard (as that gives you the VLAN option) but I have also some other setting for a guest network that I prefer not to have to reconfigure. Thanks in advance.

I did the following recently going from spark vdsl to spark fibre:

 

1. Delete the existing pppoe0 interface

 

2. Create vlan 10 using interface eth0

 

3. Create new pppoe interface, id 0, interface eth0.10, entering username/password there

 

4. Go into firewall/nat, firewall policies, and edit wan_in and wan_local interfaces to use pppoe0/in and pppoe0/local respectively (the interface with the public IP assigned to it).

That worked perfectly thank you.

If you setup ddns on the edgerouter do you use eth0 or eth0.10 (for vlan10) for the outbound interface?

The public IP is associated to the pppoe interface, so you'd select pppoe0

It doesn't allow selecting pppoe0 'set service dns dynamic interface ... '

Interesting, it's available in the drop down menu for me. I can't remember as I've got a static IP now so don't use dynamic DNS anymore.

 

 

 

Do you have a pppoe interface?

Yes I do. What I did was select other interface in the GUI and manually entered pppoe0

EdgeMAX EdgeRouter software hotfix version v1.10.2 has been released!
New firmware release 1.10.2 is available here:

 

[Release Notes v1.10.2]

 

Changelog

 

Changes since v1.10.1

 

New features:

 

  • Don't flush flows from offload module - this is experimental and optional feature which blocks offload module from flushing IP flows upon changes in Linux routing table. Once enabled it should increase throughput and reduce CPU load if routing table changes frequently (e.g. when router has Full-BGP peer). It was discussed here

    By default this feature is disabled and offload module works same way as in 1.10.1 firmware.

    Following shell command enables this feature:
    sudo bash -c "echo 1 > /proc/cavium/ipv4/ignore_cache_flush"
    Following shell command disabled this feature:
    sudo bash -c "echo 0 > /proc/cavium/ipv4/ignore_cache_flush"
    Right now this feature should be enabled manually after each reboot. If we will not detect any side effect then in next firmware this feature will be always-on by default.

    Warning - when this feature is enabled and nexthop interface in Linux routing table changes then all existing offloaded IP flows will keep using old nexthop interface up to following 12 seconds (actual flow lifetime value can be change here -> "/proc/cavium/flow_new_lifetime"). In worst case scenario if you have two WAN interfaces and WAN-1 fails then all offloaded flows that were initially forwarded via WAN-1 will not switch to WAN-2 up to following 12 seconds. 

Enhancements and bug fixes:

 

  • LDP - fixed regression in 1.10.0 when LDP configuration failed. Discussed here
  • LoadBalancing - fixed regression in 1.10.1 when LoadBalancing failed to recover if WAN interface lost&restored link in 3 second interval. Discussed here
  • DHCP - fixed bug when DHCP server configration failed to commit with networks other than /8, /16, and /24. Discussed here
  • TrafficControl - fixed regression in 1.10.0 when "command not found" output was printed when running "show traffic-control ..." commands. Discussed here
  • Offloading - fixed bug when flow lifetime was incorrect on all Cavium-based models except ER-Lite/ER-Poe causing packets to unnecessary bypass offloading, decrease throughput and increase CPU load.

Updated software components:

 

  • none

Known issues:

 

  • Bug with corrupted downloads via PPPoE interface is not fixed for ER-8-XG (it is fixed on all other ER models). Workaround - disable PPPoE offloading on ER-8-XG:configure set system offload ipv4 pppoe disable
    set system offload ipv6 pppoe disable commit save

We will publish this 1.10.2 firmware in main EdgeMAX forum, download site and UNMS in one week from now.

I have the 3 ERLite and I bought today the ER4.

Does the downloaded configuration of the lite in the 4?

I have many forwards ports configured and would not like to put back it.

Best regards.

EdgeMAX EdgeRouter software hotfix version v1.10.3 has been released!

 

 

Note: The ER-X/ER-X-SFP/EP-R6 has more limited storage, and in some cases, an upgrade may fail due to not enough space. If this happens, remove the old backup image first (using "delete system image" command, see here for more details) before doing an upgrade.

 

More details can be found in the release notes below. Please give it a try if you are interested in the new features/changes to help us test them so that we can get the release out sooner! Thanks very much!

 

[Release Notes v1.10.3]

 

Changelog

 

Changes since v1.10.2

 

New features:

 

  • none

Enhancements and bug fixes:

 

  • Offloading - Add CLI commands to disable flow-table flushing in offloading engine when routing table changes: set system offload ipv4 disable-flow-flushing-upon-fib-changes set system offload ipv6 disable-flow-flushing-upon-fib-changes
    Discussed here

    Prior to 1.10.3 firmware offloading flow table was always flushed when route was added/deleted from linux routing table. Flow flushing ensured that offloading engine got routing updates instantly but it wasted a lot of CPU time and decreased performance if routing table was constantly updated for (instance in Full BGP, big OSPF or flapping PPPoE interface scenarios)

    In 1.10.3 firmware by default disable-flow-flushing-upon-fib-changes is not set which means that flow table in offloading engine is always flushed upon routing table changes same way as it used to be in previous firmware.
     
    If you have Full-BGP table or large OSPF network they you are advised to set disable-flow-flushing-upon-fib-changes this will ensure less CPU-load and more bandwidth.
     
    Important note for multi-WAN environments - if nexthop interface of default-gateway changes and disable-flow-flushing-upon-fib-changes is set then it will take up to flow-lifetime seconds before all existing offloaded flows switch to new nexthop interface (up to 12 seconds by default).
     
  • Offloading - Add CLI command to modify flow-lifetime in offloading engine (expressed in seconds): 
    set system offload flow-lifetime 24Prior to 1.10.3 firmware flow-lifetime parameter was hardcoded and was not synchronized between different ER platforms: 12 seconds on ER-Lite/ER-Poe, 6 seconds on ER/ER-pro/ER-4/ER-6 and 3 seconds on ER-Infinity. 
     
    In 1.10.3 firmware default value of flow-lifetime is set to 12 seconds for all ER platforms and now it can be modified. By modifying flow-lifetime parameter you control how much traffic skips from offloading engine into linux network stack which is needed for conntrack and getting routing table updates from linux.

    If you increase flow-lifetime then:
     a) Offloaded IP flows will expire less frequently and less packets will be forwarded to linux
     b) CPU load will decrease and total bandwidth will increase
     c) if disable-flow-flushing-upon-fib-changes parameter is set then it will take more time for offloading engine to detect changes in routing table 
     
    If you decrease flow-lifetime then:
     a) Offloaded IP flows will expire more frequently and more packets will be forwarded to linux
     b) CPU load will increase and total bandwidth will decrease
     c) if disable-flow-flushing-upon-fib-changes parameter is set then it will take less time for offloading engine to detect changes in routing table 
     
  • Offloading - add CLI command to show flows in offloading engine:show ubnt offload flows
  • Offloading - add CLI command to show offloading engine statistics:show ubnt offload statistics

Updated software components:

 

  • none

Known issues:

 

  • Bug with corrupted downloads via PPPoE interface is not fixed for ER-8-XG (it is fixed on all other ER models). Workaround - disable PPPoE offloading on ER-8-XG:configure set system offload ipv4 pppoe disable
    set system offload ipv6 pppoe disable commit save

     

    We will publish this 1.10.3 firmware in main EdgeMAX forum, download site and UNMS on Monday May 7th 2018

I'm pretty sure this is a Bad Sign:



No internet this morning, no lights except the flickering console light and an ominous noise. Teh interwebz suggested a possibly faulty power supply, but the light on that seems solid.

Any thoughts on whether this is terminal or can be remedied?

I think ERLite 3 uses a standard DC12V 1A power input.  Do you have any other D12V 1A / 1A+ power supplies from other routers, external hard drives etc that you can try with the ERL3 and see how it goes?
