I have a very basic question. Unfortunately, I cannot figure it out… How do I know on which port a given MAC address is connected? We have a server connected to one of our switches via SFP and I’d like to know on which port. We are currently running Cumulus Linux 3.7.15. 1 post - 1 participant Read full topic ..read more

Hello guy, recently i was try upgrade the switch from 4.4.4 to 5.5.5 but some commands i can’t apply it when i use a nvue commands. I can apply below commands to my switch which running 4.4.4 net add vxlan vxlan3101-3107,3111-3114 mtu 9050 net add vxlan vxlan3101-3107,3111-3114 stp bpduguard net add vxlan vxlan3101-3107,3111-3114 stp portbpdufilter i try apply below commands it got error message. nv set interface vxlan48 bridge domain br_default stp bpdu-guard on nv set interface vxlan48 bridge domain br_default stp bpdu-filter on Config invalid at interface.br_default: {‘x-cue-marker’: ‘def ..read more

Hello Nvidia Cumulus experts, Has anyone encountered the below issue. I have only one br_default bridge. Config invalid at interface.swp21s1.bridge.domain: Only one bridge can be configured Here are the interfaces: interface swp21s0 link-speed 25000 interface swp21s1 link-speed 25000 interface swp21s2 link-speed 25000 interface swp21s3 link-speed 25000 Thanks in advance! 1 post - 1 participant Read full topic ..read more

Hi community, I am desperately looking for a sample config of a Cumulus Switch for using Azure HCI. especially how to use qos features and priority flow control. Is anyone here who already did this on cumulus OS. As switch I am using a SN2100. I am struggling covering this requirements: Cluster traffic class This traffic class ensures that there’s enough bandwidth reserved for cluster heartbeats: Required: Yes PFC-enabled: No Recommended traffic priority: Priority 7 Recommended bandwidth reservation: 10 GbE or lower RDMA networks = 2 percent 25 GbE or higher RDMA networks = 1 percent RDMA traf ..read more

Hi all, It seems that it is not possible to configure it as transparent clock, it is not clear to me whether multiple PTP domains can be configured. Does anyone have any experience with this? regards, Dan 2 posts - 2 participants Read full topic ..read more

Hi As far as I know, the ISC DHCP relay is end of life, but still part of Cumulus. I was wondering, which DHCP relay will Cumulus be using in the future? And is there one which supports RFC RFC5107? 2 posts - 2 participants Read full topic ..read more

Hi experts, I have a question regarding Cumulus Linux bridge VLAN configuration. If this is my configuration related to VLANs: admin@SW-MLNX-01:mgmt:~$ nv config show -o commands nv set bridge domain br_default vlan 99 nv set bridge domain br_default vlan 129 nv set bridge domain br_default vlan 130 nv set bridge domain br_default vlan 131 nv set bridge domain br_default vlan 132 nv set bridge domain br_default vlan 133 nv set bridge domain br_default vlan 134 nv set bridge domain br_default vlan 135 nv set bridge domain br_default vlan 136 nv set interface bond1 bond member swp1 nv set interf ..read more

Hi It seems that adding /32 routes in Cumulus / switchd causes routing to happen in software. We can add a /24 route, everything is fast and seems to be in hardware. Then we test with a /32 route to the same IP and things slow down to 4Mbps. Where can I read about when /32 routes trigger software routing? I believe the 4Mbps we are seeing is related to L3 COPP limits. Testing with SN2010, Cumulus 5.3. 8 posts - 3 participants Read full topic ..read more

Hi community, In Onyx, when I configure LACP, I have to set it to on, active or passive mode: interface ethernet x/x mlag-channel-group y mode [active, passive, on] While in Cumulus Linux, when you configure LACP, you cannot configure this setting. The documentation only says: "Cumulus Linux supports IEEE 802.3ad link aggregation mode (802.3ad) and balance-xor mode. The default mode is 802.3ad." Any idea?

@epulvino this might be a better question for you but we do quite a bit with IS-IS on Extreme. With FRR supporting the basic RFC we’re looking at a few ways we want to test but ultimately implement it on Cumulus vs VXLANs over EVPN. Are snippets the best options since NVUE doesn’t support it yet? Is there a safer way to configure FRR for these non NVUE configs? Lastly, does Cumulus/NVIDIA have future NVUE plans for configuring OpenFabric (fabricd) in FRR? 2 posts - 2 participants Read full topic ..read more
