Dell R740xd servers with OEM Intel X710 adapters were cabled to Cisco switches with SFP-H10GB-CU5M and SFP-H10GB-CU3M DACs. Two cables linked, five did not; the working ones carried a blank or V02 version ID (made 2013), the failing ones V03 (made 2019), all identified as SFP-10GBase-CX1 on the…
A short no-name DAC between a UDM SE and a Minisforum MS-01 had worked for months; a new 30 m Ubiquiti UACC-AOC-SFP10-30M active optical cable was recognised by the UDM SE (vendor, part, serial, temperrature, power visible) but no link came up and the SFP port log showed an SFP EEPROM error; on…
Intel X710/XL710 adapters refuse third-party optics at the firmwre level with the message Rx/Tx is disabled on this device because an unsupported SFP module type was detected, and the i40e driver offers no override. The repository documents a procedure to remove the check: update to a known…
On a Protectli Vault 6 with Intel X710 SFP+ ports (ixl0/ixl1) a 1G EZConn ETB43315-7S34-FR SFP showed no carrier. Logs contained Invalid advertised speed; valid flags are: 0x06, ixl1setlink: Error getting phy capabilities -37, aq error: 8 and Link failed because an unqualified module was detected!…
On a Minisforum MS-01 running Proxmox (i40e, kernel 6.8.12-10-pve) the X710 SFP+ port enp2s0f0np0 recogniesd a Ubiquiti SFP+-to-RJ45 module (ethtool listed 10G Base-SR capability) but the link never came up: Link detected: no, interface DOWN, no dmesg errors, ip link set up made no difference…
Home setup. The fibre handoff from my provider is a 1G BiDi module and I would like it in the firewall itself instead of kepeing a switch in front of the box just to convert media. Protectli Vault 6 running pfSense, X710 ports, ixl driver the provider-supplied 1G BiDi module, an EZConn…
An operator asked how to use non-Intel SFP+ modules for 10G fibrre on Intel adapters under Linux. The replies summarised the practical rules: for 82599/X520 class NICs the ixgbe module parameter allowunsupportedsfp must be set, and on dual-port cards it must be given per port…
The poster planned a server with an Intel X710-DA2 dual-port SFP+ NIC connected to two Ubiquiti EdgeSwitch 48 Lite units, with LACP between the switches. Six 10G SFP+ modules were needed (two for the server side, four for the switches) and the question was which modules would be recognised by both…
The poster's Intel Ethernet Converged Network Adapter X710 would not come up with third-party Fiberxon 10G SFP+ modules: the i40e driver, version 1.2.48, refused to initialise and reported "The driver failed to load because unsupported module type was detected." They asked how to switch on an…
The poster wanted to use a Finisar FCLF8521P2BTL 1000BASE-T copper SFP in an Intel X710-DA2 running NVM 7.1. Intel's X710/XXV710/XL710 Feature Support Matrix (rev. 3.4, Nov 2019, doc 332191-024) lists single-speed SFP 1GBASE-T transceivers with support limited to Finisar FCLF-8521-3, Kinnex A…
