Cisco 3825 на ней 4 FastEthernet interfaces
Есть линк Ethernet от провайдера.Проблема
Всё прописанно но ничего не видно даже шлюз провайдераВот кусок конфига

Подскажите плз в чём может быть дело?роут дефолтный на прова
ip route 0.0.0.0 0.0.0.0 X.X.X.Z
а VLAN провайдер понимает?

Да, пингуется.Если включаю и выключаю интерфейс появляется вот это:
Apr 25 08:13:25.726: %DTP-5-TRUNKPORTON: Port Fa0/0/3 has become dot1q trunk
Apr 25 08:13:25.946: %SPANTREE-2-RECV_PVID_ERR: Received BPDU with inconsistent peer vlan id 10 on FastEthernet0/0/3 VLAN4.
Apr 25 08:13:25.946: %SPANTREE-2-BLOCK_PVID_LOCAL: Blocking FastEthernet0/0/3 on VLAN4. Inconsistent local vlan.

А что говорит sh vlans ?
Вобще не видит вланов. Только если зайти vlan database и там уже show набрать, тогда показывает:

>Apr 25 08:13:25.946: %SPANTREE-2-BLOCK_PVID_LOCAL: Blocking FastEthernet0/0/3 on VLAN4. Inconsistent local vlan.Попробуй следующее:
no spanning-tree vlan 4,10
На интерфейсе Fasta:
switchport nonegotiate

>На интерфейсе Fasta:

(config)# int fa0/0/3
(config-if)# spanning-tree bpdufilter enable
>IMHO лучше так -
>(config)# int fa0/0/3
>(config-if)# spanning-tree bpdufilter enable
И не забыть switchport mode access
