I have a server that shared the ethernet port for the NIC and the IPMI. I want to associate a vlan (10) to IPMI and use the native vlan 1 for the NIC. I use a 2960G switch, the ports are configured in mode trunk and nonegotiate.
The IPMI configured in the vlan 10 not respond (arp, ping). Moreover, if I replace the cisco switch with a non manageable switch everything works OK. What is wrong in this trunking configuration?
Regards,
Liana

Hi
You haven't defined the encapsulation on interface GigabitEthernet0/10 , unless the switch automatically is set to a trunking encapsulation e.g dot1q.

Hi Dan,
In 2960 series only dot1q is supported so the "switchport trunk encapsulation dot1q" command is not supported.

Why is the switchport configured as a Trunk instead of a switchport access vlan 10?

I want to use the native vlan 1 for the ethernet interface of the server (the IPMI and NIC are connected on the same switch port). Moreover, the IPMI is already configured in vlan 10.
