Hi all, I have a customer that is trying to connect some ESX hosts at 10g to a recently commissioned EX4500 VC.
Their ESX hosts are IBM servers, and they were supplied with the following DAC cables: Cable: IBM Twin-ax Active Cable 5M, PN: 45W3039 Cable labelled as: Brocade 10G Active 5M FCoE, 58-1000023-01 The (two-member) EX4500 VC is running JUNOS 12.1R1 (mostly due to this release being the first to officially support "active" DAC cables). The EX4500 detects the interface when plugged into an SFP+ slot but the line speed/link-up speed is 1g (ge-*), not 10g (xe-*). Note there are no uplink modules installed; we're going directly into the built-in ports. Other info: ESX Version: ESX 4.1.0 Build 582267 Adapter Model: IBM 42C1801 ESX networking driver: qlgc-qlge-1.0.0.45-100.27-offline_bundle-418618 Has anyone experienced this before? JTAC didn't provide much insight, other than to try a Juniper branded cable (e.g. EX-SFP-10GE-DAC-5m or EX-SFP-10GE-ACT-5M). So, that's our next step. Any other tips? cheers, Dale _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
