Problem with 9200 and 9500 truking with SFP+ (10G-LR)

chpaul13

Level 1

Hello,

I configured a link trunk between a 9200 and a 9500 with SFP+ (SFP-10GBase-LR)
but it does not work. the 9200 sees the 9500, the 9500 does not see the 9200 (with "show cdp neighbors"). On the 9500, 0 packets input...

When I test with an rj45 port, it works.

With the same 9500 I have no problem with 9200L...

Thanks for your help !

Check ports on 9500 SFP connect with the supported 10G port..

The Cisco Catalyst 9500 Series Switches family consists of fixed core and aggregation layer switches supporting redundant power supplies and modular fans. The Cisco Catalyst 9500 Series offers switch models with downlink ports of the following types:

  • 8 ports of 400G QSFP-DD

  • 16, 28 and 32 ports of 100G QSFP28

  • 12, 24 and 32 ports of 40G QSFP

  • 24 and 48 ports of 25G SFP28

  • 16, 24, 40 and 48 ports of 10G SFP/SFP28

Below is the both switch hardware installation guide..

Hello,

For all, I've already changed all Gbic, fiber, I put the two switch side by side with just a garter between them. I also tested with a DAC cable.

The strangest thing is that on the 9500 there is "0 paquets input"

Post the complete output to the command "sh version" from both switches. 

There is an uptime bug that occurs with the 9500 where it would cause the SFP ports to randomly stop passing traffic.

  1. Are both ends using LR optics?
  2. Are both ends using single mode OS2 patch cables? 
  3. What is the distance between the two optics?

for me the problem doesn't come from there, because I installed the two equipments side by side, I put a direct DAC cable and there is the same problem...

What is the exact model of the DAC cable and where is the DAC head-end installed, on the 9500?
