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.
Solved! Go to Solution.
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).
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.
