Virtualization driving me crazy.
3750 switch connects to Blade-switch_1 and Blade-switch_2
Spanning-tree mode is configured as rapid-pvst on 3750 switch, do I need to configure rapid-pvst on both blade-switches or keep the default pvst config.
3750 is running VTP domain HQ and transparent mode
Both Blade_switches are running VTP domain CLI and transparent mode
To configure Etherchannel between 3750 and blade-switch_1 do I need to have all devices in same vtp domain
Yes sam, and also remove port-security aging time, i suppose it is a command from an old config.
That command will be used in this cases:
I have understand, i suggest the things i write before, and even if not necessary because you only have one "core" configure the rpvst on the blade if possible. If in future you will have possibility to add another core in case of faillure the different time of convergence between two protocol can create a temporary loop. Why you use a bpduguard on trunk? you will receive bpdu on that interface and the link will flap. Portfast trunk is not necessary with rpvst. Keep attention on 3020 with channel group on it's reccomended to use active or passive.
