Problem
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.
Configuration
Cisco:
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
HP:
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
Commentary
- The SG500-52 was here when I got here.
- We've seen autonegotiation fail before, haven't we Cisco?
