Hello,
I have two CSS610-8G-S2+ which I want to connect via SFP+ Fiber link.
My Router is connected to Switch1 via Trunk on port 7. This is working fine, I can get IPs from DHCP from several VLANs on Switch1.
If I try the same on Switch2, I do not get DHCP-IPs, if I use the SFP+ Ports, if I use an 1G Ethernet-Port it's also working.
I have the following VLAN-Konfiguration on both switches:
* VLAN-Modes:
* VLAN-Ports:
The SFP+ Ports are Up and the Switch says that they are running with 10G.
Here the SPF-Infos:
This is my Port Isolation Configuraiton:
And there are no ACLs.
At the Stats I see traffic over the SFP+ Link:
And I have NO errors on all ports.
Finally here the system Infos
Has someone an idea, what could be the reason, why the trunk is not working via SFP+, only via Ethernet Cable?
Thanks for your help
Tom
