Nexus 9348 ports speed capability

Hello,

I found documentation discrepancy about the ports speed capability of the Nexus 9348GC-FXP.

The datasheet from Cisco is : https://www.cisco.com/c/en/us/products/collateral/switches/nexus-9000-series-switches/datasheet-c78-742284.html

 

This datasheet mentions about the ports configuration:

 

1) "4 x 10/25-Gbpp SFP28 ports"  (see table 2 of the doc) 

2) "The 4 ports of SFP28 can be configured as 1/10/25-Gbps"  (see figure 3 of the doc)

 

Both statements above are contradictory. So do these 4 ports support 1-Gbps or not?

 

I tried to connect a 1-Gbps SFP (which is correctly detected) but the link doesn't come up, despite being serviceable (I have tested on another non-Nexus switch).

Worth mentioning that a "show interface" on the switch gives this output: "Hardware: 1000/10000/25000 Ethernet".

 

Thanks a lot in advance.

Spoke with one of the PMs and they noted that the 4p SFP28 can support 1/10/25G.

The datasheet will be updated to reflect that consistently.

Personally I do not believe this support 1GB

 

9348GC-FXP. - 4 x 10/25-Gbps SFP28 port  - as I remember it was not worked for me when i was installed for one of my customers some time back, even though it was detected.  If I recall I have to use 10GB  for uplink to a parent switch.

 

(not sure if the things were changed here).

I agree with Balaji.

The 9348GC-FXP specific model does not seem to support 1Gb on those ports.

Good to know "1/10/25G" has support - is this tested ?

Thanks a lot for your answers.
Yes I have just tested and I confirm that I was able to make these ports come up at 1-Gbps with 1000BASE-SX transceivers. 

Good to know that the documentation will be updated accordingly.

 

Thanks!
