Hello Experts, 

I converted the vcp ports to network ports of EX-4100. When I connect the interface ge-0/1/3 of EX4100  to a Juniper switch, the interface is up and I can ping the remote Juniper switch. However, when I connect the port ge-0/1/3 of EX-4100 to Cisco ASR, the interface ge-0/1/3 shows up but the interface of Cisco ASR shows down. The Cisco ASR interface is set to full-duplex and auto-nego. I see the interface of ge-0/1/3 doesn't have the duplex settings and I don't see the option to set the duplex on ge-0/1/3. Can you tell me how to set the duplex on ge-0/1/3 of ex-4100? I appreciate your help.

You generally need to turn off auto-neg and set both speed and duplex manually when these missed negotiations occur.  I think these are the three commands you'll use.

Hi,

On the ex4100 the command to set the duplex on an interface is:  set interfaces ge-0/0/9 link-mode full-duplex

Hope this helps

Hi Marcel, 

Thank you for your response. I am using EX4100-F-12T model.  I do see the option for link-mode on the copper ports but not on the fiber uplink ports. I converted the vcp ports to the network ports. I found this KB below.  When I try to set to no-auto-nego, I get the error.

I got it working. I had to set the speed first and commit, then disable the auto-nego using gigether-options and then commit again.

Thank you,

Hi,

On the ex4100 the command to set the duplex on an interface is:  set interfaces ge-0/0/9 link-mode full-duplex

set interfaces ge-0/0/9 link-mode ?
Possible completions:
  full-duplex          Full-duplex operation
  half-duplex          Half-duplex operation

Hope this helps 

Marcel

Hi Steve, 

Thank you for your response. I don't see the option for link-mode to set the full-duplex.

Thank you,

You generally need to turn off auto-neg and set both speed and duplex manually when these missed negotiations occur.  I think these are the three commands you'll use.

set interfaces ge-0/1/3 gigether-options no-auto-negotiation

Hello Experts, 

I converted the vcp ports to network ports of EX-4100. When I connect the interface ge-0/1/3 of EX4100  to a Juniper switch, the interface is up and I can ping the remote Juniper switch. However, when I connect the port ge-0/1/3 of EX-4100 to Cisco ASR, the interface ge-0/1/3 shows up but the interface of Cisco ASR shows down. The Cisco ASR interface is set to full-duplex and auto-nego. I see the interface of ge-0/1/3 doesn't have the duplex settings and I don't see the option to set the duplex on ge-0/1/3. Can you tell me how to set the duplex on ge-0/1/3 of ex-4100? I appreciate your help.
