FastEthernet0/1 - FastEthernet0/24 работают как порты коммутатора. На эти порты IP можно назначить только через vlan
GigabitEthernet0/1 - GigabitEthernet0/2 работают как порты коммутатора. На эти порты IP можно назначить только через vlan

2. По DHCP чистая конфигурация, в отличие от 831, не захотела получать IP-адрес.

3. Последовательность команд после erase startup-config и reload:

#enable
#conf t

no service pad

#end
#write

#conf t
#vtp mode server
#vtp domain vtp_domain_name_here

#exit
