Hello, I'm having issues with loops on Cisco Nexus 3524-X connected with Ubiquiti Devices and Meraki Devices. The topology is somewhat complex, so I will try to be as thorough as possible. Have two Cisco Nexus 3524-X stacked ( vPc ). One Port channel ( Ports 31 on both Nexus switches ) , trunked connected to Ubiquiti Core switch. Single Port 29 connection from Nexus-1 to Ubiquiti Firewall ( trunk allowed vlan 9 ) for the uplink of Ubiquiti public network ) Port Channel 33 is the uplink to Cisco Meraki ( access on vlan 1 ) . Port channel 34 is the connection to Meraki LAN network ( trunk allowed vlans 2-1600 ) Port Channels 2-5 are trunked to a Proxmox Server Cluster. Port Ethernet 1/45 is the link to our ISP. The problem is when connecting to the Ubiquiti network, a loop happens and it brings all network down ( Ubuquiti + Meraki + Cluster ). I'm trying to understand where is the loop(s) happening and how to solve them. Any help would be highly appreciated. I am attaching configuration of the two Nexus switches plus the logs I've gathered from the loops.

Hello, @balaji.bandi Unfortunately, the command service unsupported-transceiver does not exist. I've read in some forums that t he command "service unsupported-transceiver" is no longer available. I guess I'll have to buy another sfp cable then... Any recommendations on what cable will absolutely and definitely work? Best Regards, Panagiotis Botos

Hello, I have removed the previous cable connections and made new ones using only sfp cable. So I have connected Nexus-1 (port 10) -> Catalyst-1 ( SFP Port - 25 ) . Still no link light. On the Nexus-1 switch I do not see something wrong in the logs: #show logging 2019 Mar 13 13:46:57 Nexus-1 %ETHPORT-5-IF_HARDWARE: Interface Ethernet1/10, hardware type changed to No-Transceiver 2019 Mar 13 13:46:57 Nexus-1 %ETHPORT-5-IF_DOWN_NONE: Interface Ethernet1/10 is down (Transceiver Absent) 2019 Mar 13 13:52:30 Nexus-1 %ETHPORT-5-IF_HARDWARE: Interface Ethernet1/10, hardware type changed to Transceiver-Present #show interface tranceiver detail : Ethernet1/10 transceiver is present type is SFP-H10GB-CU3M name is CISCO-TYCO part number is 1-2053783-2 revision is R serial number is TED1725B5RZ nominal bitrate is 10300 MBit/sec Link length supported for copper is 3 m cisco id is 3 cisco extended id number is 4 On the Catalyst switch though I see some error: It seems that for some reason the Catalyst does not like the cable ? Please help me resolve this issue. Best Regards, Panagiotis Botos

So, I tried using an sfp to ethernet converter and connected port 10 on catalyst ( ethernet port ) , to port 10 on Nexus (sfp port with the module installed). This is the output I get: Eth1/10 -- sfpInvali 1 full 10G 1000base-T Nexus-1# show interface ethernet 1/10 transceiver details Ethernet1/10 transceiver is present type is 1000base-T name is FiberStore part number is SFP-GB-GE-T revision is B serial number is G1804168621 nominal bitrate is 1300 MBit/sec Link length supported for copper is 100 m cisco id is 3 cisco extended id number is 4 DOM is not supported Nexus-1 %ETHPORT-5-IF_HARDWARE: Interface Ethernet1/10, hardware type changed to Transceiver-Present Nexus-1 %ETHPORT-5-IF_DOWN_NONE: Interface Ethernet1/10 is down (None) No configuration has been done on port 10 whatsoever (only the no shut command).

Hello, I am trying to connect our Cisco Catalyst 2960L-24TS-LL with our Cisco Nexus 3524-X. Tried connecting the SFP of Catalyst to one SFP of Cisco Nexus but the connection will not work. After checking the logs, I can see in the Catalyst that the SFP module is not compatible, although it is a Cisco one and bought it according to compatibility matrix. Can anyone please suggest me, how to connect these devices? Thanks in advance.
