routing between vlans -- slow speed on an APU4



  • Greetings,
    I recently got my hands on a vmware esxi server, and on that server, there are a variety of vlans.

    I configures my APU for a trunk port, and connected a cable directly to the VMWare server.

    The APU is a router on a stick, and routing between vlans works fine, but ...

    I used rsync between two vlans and was surprised to see a 1.2M throughput. I have Cisco gigabit switches, and the server is a monster. There are no traffic policies being used. The port is connected at 1gbit full duplex

    re1.1601: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
    options=80003<RXCSUM,TXCSUM,LINKSTATE>
    ether 0e:0e:be:3e:ae:ee
    inet6 fe80::2ee:beee:feee:abee%re1.1601 prefixlen 64 scopeid 0x8
    inet 172.16.1.254 netmask 0xffffff00 broadcast 172.16.1.255
    nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
    media: Ethernet autoselect (1000baseT <full-duplex,master>)
    status: active
    vlan: 1601 vlanpcp: 0 parent interface: re1
    groups: vlan

    Any thoughts or is this expected speed?

    Thanks

    M

    Whether that's 1.2Mbps or 1.2MBps both are incredibly slow. It would seem there is something basic at fault there.
    The re NIC in the your output implies you have a 4GB APU1 rather than the new APU4 board, correct?

    You should disable all hardware off loading features in System > Advanced > Networking.

    It may be necessary to disable for hardware VLAN tagging though I'm not aware of any specific issue there.

    Check Status > Interfaces for errors.

    Check the connected switch for logged errors if it logs that.

  • Just have some curious questions.

    • Just for clarity, by APU4, do you mean a Netgate APU4?
    • What model switches are you using?
    • Why did you trunk your ESXi box directly to your firewall instead of to the switch?

    Wow -- that did it! Move the needle to a stunning 581mbits a second.

    Huge thanks -- awesome!!!

    What specific thing corrected it for reference?

  • Even though it's "working", you should still re-visit your design. I wouldn't plug your server directly into your firewall.
