I'm working on a client's H3C S5820X-28S switch. I'm thoroughly unfamiliar with H3C (which, as I understand, is just an pre-buyout HP switch) having only touched Cisco and some Juniper switches.

Anywho, I have a 10Gig port That appears to be configured, but refuses to turn on for some reason. It's in a remote datacenter and I have eyes on the switch that say that we have it patched properly, but not getting link. I've managed to pull up its current config and this is what it's set to:

 [conf]display interface Ten-GigabitEthernet1/0/14
 Ten-GigabitEthernet1/0/14 current state: DOWN
 IP Packet Frame Type: PKTFMT_ETHNT_2, Hardware Address: 3822-d6e5-3763
 Description: Ten-GigabitEthernet1/0/14 Interface
 Loopback is not set
 Media type is stack wire,Port hardware type is STACK_SFP_PLUS
 10Gbps-speed mode, full-duplex mode
 Link speed type is force link, link duplex type is force link
 Flow-control is not enabled
 The Maximum Frame Length is 10000
 Broadcast MAX-ratio: 100%
 Unicast MAX-ratio: 100%
 Multicast MAX-ratio: 100%
 Allow jumbo frame to pass
 PVID: 101
 Link delay is 0(sec)
 Port link-type: access
 Tagged   VLAN ID : none
 Untagged VLAN ID : 101
 Port priority: 0

         0 lost carrier, - no carrier

I've manually enabled/disabled the port with shutdown/undo shutdown but still cannot get it working. Is there something that I may have missed in the config?

Media type is stack wire,Port hardware type is STACK_SFP_PLUS

You haven't said what's being connected to the port, or if there are any syslog errors (presumably of an "unsupported" SFP) Run "display transceiver interface" to see what it thinks about the module(s). Your output shows a direct-attach cable is plugged in.

  • [conf-Ten-GigabitEthernet1/0/14]display transceiver interface Ten-GigabitEthernet1/0/14 transceiver information: Transceiver Type : STACK_SFP_PLUS Connector Type : COPPER Wavelength(nm) : N/A Transfer Distance(m) : 3(TP) Digital Diagnostic Monitoring : NO Vendor Name : H3C Ugh... can't get the formatting right. Anyways, this is the output. – misterjones Dec 11 '14 at 4:03
  • Found a syslog entry as well OPTMOD Warning MODULE_IN Ten-GigabitEthernet1/0/14: The transceiver is STACK_SFP_PLUS. – misterjones Dec 11 '14 at 4:14

I realize this is an old post, but the issue turned out to be a bad tranceiver. Ordered a new one and everything was up and running just fine.
