fc port setting

I need to find out my fiber channel port speed setting is 1Gbps, 2Gbps or autonegotiate.

I do the fcmsutil /dev/td0 command.

It show me the speed of the port 2Gbps. Can I say the speed is fixed to 2Gbps not auto-negotiate.

FC device file: /dev/td0

Vendor ID is = 0x00103c
Device ID is = 0x001029
XL2 Chip Revision No is = 2.3
PCI Sub-system Vendor ID is = 0x00103c
PCI Sub-system ID is = 0x00128c
Topology = PTTOPT_FABRIC
Link Speed = 2Gb
Local N_Port_id is = 0x020100
N_Port Node World Wide Name = 0x50060b0000243bd5
N_Port Port World Wide Name = 0x50060b0000243bd4
Driver state = ONLINE
Hardware Path is = 1/0/2/0/0
Number of Assisted IOs = 974219

Hi

You:Can I say the speed is fixed to 2Gbps not auto-negotiate.

Me: Yes

It is downwardly compatible and should run on a n older 1 GB/s. It should run at 2 Gb/s on a 4 GB/s san
