NetVanta an Dell R740 10GB port not working

[Anonymous]

hi, guys i have a Dell Server R740 whit two 10GB ports connect to NetVanta 1534P Firmware R11.10.1 the issue is the server linkup on the switch, but i  don't have trafic, if a connect the two 1GB ports on the same server and switch they work fine.

2 things I had trouble when I went to a 10G, 1 improper SFP (Adtran 1638 didn't recognize) 2 I had to hard code SFP 10000 link speed.

in my case I am using coaxial network cables, I am not using fiber optics

Hi,

• I would upgrade to R13.2.3 ( Latest EMR for this switch, for SFP compatability ) and
• The 1534P max speed is 2.5 Gbps on ports 0/27 & 0/28.
  • 2.5Gbps is SFP dependent and is not supported by most 1 Gbps SFP's
• If the server is a VM kind of server these connections can be both connected to a Vswitch.
  • Check your spanning-tree design and that you are not blocking on any ports
  • Some servers will use one and the second connection is a failover
• They also may be trying to do LACP ( what we call Port-Channels).
  • Adtran 1534 Supports static port-channels ( no negotiation )
    • This is not the default on VM or Linux servers
    • This is also not the default on Windows Servers
