Switch MDS 9250i to WS-C3850-48T

Hi People, 

 

I'm new here!

 

I have a litte problem regarding the bandwitdh of 2 switches. It's between a switch MDS 9250i and a Switch Backbone IOS-XE ROMMON. Thery are linked with a 10Gbps fiber. The problem is that they never pass from 1Gbps. 

 


interface TenGigabitEthernet2/1/3
description XXXXXXXXX
switchport access vlan 522
switchport mode access
end

 

interface IPStorage1/2
ip address 172.16.36.161 255.255.255.224
no shutdown

 

My colleagues and I have verified all the both configs and the negotations of the ports and they are properly well.

No QoS, policies or other networks devices are between them. But they stop always at 1Gbps it seems like a threshold.

 

Cold you give me some help? I'm not finding what can be causing this.

 

Many thabks in advance!

Hi again, 

 

After revising all the configs we aren't able to find what's causing this. If anyone have any idea it would be much appreciated.

 

Best regards,

Roger

After some tests, the problem seems to persist. There's no way to increase the speed more than 1Gbps between these two switchs. 

 

If anybody has some ideas. 

 

Many thanks in advance
