I am trying to create an HSRP channel between a Cisco Catalyst 2970G and a Cisco Catalyst 3850. The port (Gi0/10) on the 2970G is shown as suspended (LEDs are amber). The port (Te1/0/14) on the 3850 is shown as not connected (though the LEDs are green).

For both the 3850 and the 2970G, I have included the output of sh vtp status, the port configuration, and the output of the interface status (sh int te1/0/14). On the 2970G, I have also included the output of sh log that reflect a VTP domain mismatch.

From the output of sh vtp status, I see that there are different VTP versions between the switches. I also see that from the output of the log, the 3850 does not have LACP enabled.

Any assistance is greatly appreciated.
