Transceiver reseller from Surabaya. Mostly ISP backbone.
The poster had third-party SFP+ optics for both the on-board Intel X553 ports of a Netgate XG-7100 and an add-in X520-DA2 and had found that hw.ixgbe.unsupportedsfp=1 in /boot/loader.conf enables them. Questions: does it apply to both on-board and PCIe Intel ports, what is the difference between…
The poster operated old HP/H3C A5800 switches (JC100A, JC103A) with many SFP modules of mixed coding. Modules with H3C in A0h bytes 60h-62h worked but logged This is not a supported transceiver for this platform, and DDM plus serial/date information were unavailable. Copying the full data from a…
The poster tried to link an HPE FlexFabric 5900AF and a Dell S5212F-ON at 10 Gbps with DAC cables that had been custom-made with an HPE-coded end and a Dell-coded end. Both ports were forced to 10G full duplex, but no link came up. On the HPE side the interface reported Media type is stack wire…
The poster spent two days trying to bring up a single-mode fiber link between an older Arista switch and a Cisco Catalyst 3650 (IOS-XE 3.7.5) with Cisco GLC-LH-SMD (SFP-LH-SMD) optics; the path runs through five patch cords in the same building and had been tested by the cabling contractor. At…
The poster, a new owner of a Cisco Nexus 93180YC-EX running NX-OS 7.0(3)I4(7), cannot bring up any 25G link. ipolex SFP28 DAC cables are recognized ('type is SFP-H25GB-CU1M', 'name is OEM', 'part number is SFP-H25G-CU1M', 'nominal bitrate is 25500 MBit/sec', 'DOM is not supported') but the port…
The poster has a stack of two Cisco Catalyst 3850-48T switches, each fitted with a 2x1G/2x10G fiber uplink network module. Two 10G fiber links already run in slots 2/1/3 and 2/1/4. When a single-mode 1G SFP is inserted into 1G slot 2/1/1, the switch reports the module as unsupported and places the…
