These two switches are replacing two older Procurve swithces. These two are located in separate cabinets and trunked together. The procurves with a single trunk, but my plan was to use two of the 4 10Gbit ports on the SuperMicro as trunk ports between the switches.<br /><br />What would be simplest "up and running with NO VLANs (or "default") active at the moment and an active trunk between sw01[swp49,swp50] and sw02[swp51,swp52] ? All interfaces should connect to all other switch ports.. (this is a "I got to get this thing up and running now, and add extra features later" plead :) )<br /><br />Thanks in advance!<br /><br />Thor question 2 2 1 comment http://m.getsatisfaction.com/topics/7541609 7541609 dhcp fixed address based on chassis serial number 2017-06-21T19:33:42Z 2017-06-21T13:06:48Z cumulusJunkie http://m.getsatisfaction.com/people/9153382 https://www.gravatar.com/avatar/a0bc86e86995c2923d9f570dda1a8296?d=identicon&s=55&r=PG yemi_salau dhcp fixed address based on chassis serial number<br /><br />We know we can reserve fixed address in&nbsp;isc-dhcp-server based on device mac.<br />IETF shows serial number could be supplied as part of dhcp-client-identifier options in the DHCPREQ.<br />Did cumulus implement this with serial number?<br />The goal is, trying to assign hostname to device based on serial number, using DHCP.<br />If this is not possible, then has anyone done similar thing using ZTP with CUMULUS-SERIAL option within the HTTP-REQ headers?

&nbsp;I have been evaluating a number of SD-WAN vendors and most of their demos trail off with connecting their product to "some switch" via dot1q sub-interfaces. &nbsp;There is value in being able to connect a switching product to an SD-WAN appliance and be able to benefit from ZTP, automation &amp; orchestration, and PoE. &nbsp;The smallest hardware switch that fits this bill is the&nbsp;AS4610-54P, but even then it is still a bit too much for most branch offices. &nbsp;A more modestly sized appliance at 8 to 24 1 Gbps interfaces that supports PoE on most to all interfaces would be ideal. &nbsp;I could also see a "trimmed" down version of the Cumulus NOS since not at all features that are required for data center operations are needed at the branch... but could be if campus fabrics are considered. idea 3 3 1 comment http://m.getsatisfaction.com/topics/7363739 7363739 Ansible not able to overwrite the file 2017-06-10T01:32:26Z 2016-11-24T10:26:35Z machiasiaweb http://m.getsatisfaction.com/people/8646794 https://www.gravatar.com/avatar/51df74a2557ebb6b4a64ccd9185e885b?d=identicon&s=55&r=PG machiasiaweb_machi_ma Hello,<br /><br />I following the KB<br /><a href="https://support.cumulusnetworks.com/hc/en-us/articles/205014637-Ansible-Simple-Playbook-Example-with-a-Quagga-Template" rel="nofollow" target="_blank" title="Link https//supportcumulusnetworkscom/hc/en-us/articles/205014637-Ansible-Simple-Playbook-Example-with-a-Quagga-Template">https://support.cumulusnetworks.com/hc/en-us/articles/205014637-Ansible-Simple-Playbook-Example-with...</a><br /><br />to which overwrite quagga config.&nbsp; It got an error <br /><br /># ansible-playbook simple_updatequagga.yml -v<br />Using /root/cumulus_ansible/playbook/ansible.cfg as config file<br /><br />------------------------<br />PLAY [cumulus_vx] **************************************************************<br /><br />TASK [setup] *******************************************************************<br />ok: [cumuslusvx2]<br />ok: [cumuslusvx1]<br /><br />TASK [write the quagga config file] ********************************************<br />fatal: [cumuslusvx2]: FAILED! =&gt; {"changed": true, "failed": true, "msg": "Destination /etc/quagga not writable"}<br />fatal: [cumuslusvx1]: FAILED! =&gt; {"changed": true, "failed": true, "msg": "Destination /etc/quagga not writable"}<br />&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; to retry, use: --limit @/root/cumulus_ansible/playbook/simple_updatequagga.retry<br /><br />PLAY RECAP *********************************************************************<br />cumuslusvx1&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; : ok=1&nbsp;&nbsp;&nbsp; changed=0&nbsp;&nbsp;&nbsp; unreachable=0&nbsp;&nbsp;&nbsp; failed=1<br />cumuslusvx2&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; : ok=1&nbsp;&nbsp;&nbsp; changed=0&nbsp;&nbsp;&nbsp; unreachable=0&nbsp;&nbsp;&nbsp; failed=1<br />----------------------------------<br /><br />I found the file owner and group is quagga.&nbsp; However, even I tried to add parameters to specify owner, group and mode but still fail<br /><br />====<br />template: src=/root/cumulus_ansible/playbook/quagga.j2 dest=/etc/quagga/Quagga.conf owner=quagga group=quagga mode=0644<br />====<br /><br />Does it have any places caused it got fail?<br /><br />Thanks! question 11 3 1 comment http://m.getsatisfaction.com/topics/7521404 7521404 iptables connection tracking for the control plane?
