I was transferring a port channel from a 3750 to a 3850 stack. When I check the log on the 3850, I have those errors:
%FED_PM_ERRMSG-3-HW_ERROR: MEMBER: 3 fed: Port Manager error -port mode dtp: hardware update failed.
Everything is working ok but I just want to make sure I didn't miss something.
description Etherchannel connection
switchport trunk native vlan 99
switchport trunk allowed vlan 10,97,210,802,988,989
switchport mode trunk
spanning-tree portfast trunk
Maybe it's when I patched them? Like when I patched the first port the stack detected 3 other members were not patch yet??
