ICX7850-48F 1gb link to ICX7450 SFP shows up/down (TSB 2019-001)
When connecting an ICX7850-48F at 1 GbE speed to an ICX7450 SFP port configured for 1 GbE, the link shows up on the ICX7850-48F but shows down on the ICX7450 switch. This is due to a miss-match of the auto-negotiation port mode for the two switches.
