I have a HPE FlexFabric 5940 (JH397A 2-slot switch with 2x 48port 10Gb RJ45 + 2 QSFP+) that I need to plug into a Cisco Small Business SG500-52, but it isn't passing packets correctly.

VLAN defininition:

Make sure the PVID on both sides is VID1, and deny VLAN 1 access to the port.

Speed negotiation

Disable auto negotiation, hardcode 1Gb and Full Duplex to both sides.



interface gigabitethernet1/1/49
 no negotiation
 lldp optional-tlv port-desc sys-name sys-desc sys-cap 802.3-mac-phy 802.3-lag 802.3-max-frame-size
 switchport trunk allowed vlan add 197,218-219


interface Ten-GigabitEthernet1/2/23
 port link-mode bridge
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 197 218 to 219
 speed 1000
 duplex full
 undo jumboframe enable


  • The SG500-52 was here when I got here.
  • We've seen autonegotiation fail before, haven't we Cisco?

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
