Trunk between Dell OS10 and Cisco
Hello together
I'm trying to make a trunk between a Dell and Cisco switch. Unfortunately it does not work...
Does anybody see the error?
=========================
CISCO
=========================
interface Gigabitethernet 2/0/28
description “Interconnect"
switchport trunk encapsulation dot1q
switchport trunk native vlan 2
switchport trunk allowed vlan 2-300
switchport mode trunk
=========================
DELL
=========================
interface ethernet 1/1/34
description “Interconnect"
switchport mode trunk
switchport access vlan 2
switchport trunk allowed vlan 10-300
speed 1000
flowcontrol receive off
spanning-tree disable
I need to adjust the dell configuration so its fits the cisco configuration.
Thanks for your help.
Best Regards

Hello Ainder,
please post the output of "show interface" for each port and specify the switch models and media used for the connection.
Switchport configuration looks ok but I guess the link does not come up.

The Switch Model is S5232F-ON
The port comes up. When run show interface I can see that the interface is UP and set to 1000M.
But I think this is the problem, it is a 100G switch. Port 1/1/34 is a 10G port with SFP+. I use a tranceiver for 1 GB. Maybe this is not supported.
But strangely enough the port is UP and is blinking orange.
PS: The "show interface" output is maybe not usable yet, since the transceiver is not connected. I can you test during a maintenance window.

1G transceivers are supported in the SFP+ ports of the S5232F as well as in the QSFP28 slots via QSA28.
If the link/protocol comes up there is no compatibility issue.
I notice the Dell switch has output counters incremented but nothing on the input side.
This might indicate the port is in STP blocking state on the Cisco side.
