Re: v6.48 [stable] is released!

I noticed that when using a CRS317 as Port Controller and a CRS309 as Port Extender, once the link between the two devices fails the Port Controller completely stops forwarding and is not accessible anymore. It stays in the locked up state until the link to the Port Extender is restored. This behavi...

Re: v7.1beta3 [development] is released!

Re: v7.1beta3 [development] is released!

I'm testing beta3 on my CRS309-1G-8S+, the update went smooth. One thing i instantly noticed is that /export never terminates. Tried to reset to an empty configuration, same thing. When i run /export verbose the last thing that gets displayed is /radius incoming set accept=no port=3799 and then it h...

Re: OVPN Certificate Issue

error=unsupported certificate purpose
this.

the output of `openssl x509 -in C:\\Users\\someone\\OpenVPN\\config\\cert_export_MY-CA.crt -text` would be helpful, to see what attributes are set in the certificate.

Re: CRS3xx L3HW offloading MTU problem

Hi, I re-ran the test and during the test the connection list was empty as expected but throughput was even worse this time, around 2.2Gbit. Then, just to be sure, i net-installed beta2 again to get a completely fresh setup, reapplied the config and wonder why, now i can push up to 9Gbit through the...

Re: CRS3xx L3HW offloading MTU problem

Hi,
for IPv4 this is certainly true. For IPv6 (in the future) at least ICMP6 'packet too big' will be needed. For IPv4 'packet too big' would be nice as well, as the switch chip surely doesn't do packet fragmentation, or does it?

Re: CRS3xx L3HW offloading MTU problem

Hi, @skylark: I've sent in a supout.rif. @raimondsp: Yes, 172.17.30.1 and 192.168.89.1 are the same device. Both interfaces are configured the same in terms of firewall rules, no QoS happens on the device. Another question thats popped up, if L3HW offloading is enabled, the CRS309 does not show up i...

Re: CRS3xx L3HW offloading MTU problem

Yes, I have seen that as well and corrected earlier.
So you are saying nothing is basically wrong with that config? I'll then put the device in an isolated environment, not connected to existing infrastructure and do some more debugging. I'll come back if i figure something out.
Thanks for the help.

Re: CRS3xx L3HW offloading MTU problem

As i said in my first post, on my regular infrastructure I am able to push ~10Gbits with the same Endpoints and an MTU of 1450. It's not like I would try to saturate the Link with 40byte packages.

CRS3xx L3HW offloading MTU problem

I finally found some time to play with the new beta and L3HW offloading in particular. I did configure two networks, one attached to my client and the other pointing into my regular infrastructure, added a route and activated l3hw offloading. a few unexpected reboots later (yes i know, console only ...

Re: dhcpv6-client receive dns name from options

well, that's quite unfortunate. i did try the setup running on ROSv7, but there i'm not able to add any ipipv6 tunnel interface, as it fails for unknown reason in any possible configuration. a bit unstable still. also, i haven't come across that piece of documentation, where are you quoting from? th...

Re: dhcpv6-client receive dns name from options

The manual doesn't say anything about that, exactly my reason to ask here (:
Shouldn't this be a common use case, receiving configuration data via dhcp(v6)?
