Друзья, помогите советом!С одной стороны - 2821 + 3560 (intervlan routing).
C другой - 2960.
Вопрос:
Откуда, мягко говоря, мP-4-NATIVE_VLAN_MISMATCH: Native VLAN mismatch discovered on FastEthernet0/23 (6), with CS2960-CITS FastEthernet0/9 (1) ?
Доп. инфо:
1) На 3560 все порты, кроме линка к 2821, в режиме access.
2) На 2960 все порты в режиме access и в VLAN 1
2) show int fa0/23 switchport (с 3560):
Name: Fa0/23
Switchport: Enabled
Administrative Mode: dynamic auto
Operational Mode: static access
Administrative Trunking Encapsulation: negotiate
Operational Trunking Encapsulation: native
Negotiation of Trunking: On
Access Mode VLAN: 6 (VLAN0006)
Trunking Native Mode VLAN: 1 (default)
...
3) show int fa0/9 switchport (с 2960):
Name: Fa0/9
Switchport: Enabled
Administrative Mode: static access
Operational Mode: static access
Administrative Trunking Encapsulation: dot1q
Operational Trunking Encapsulation: native
Negotiation of Trunking: Off
Access Mode VLAN: 1 (default)
Trunking Native Mode VLAN: 1 (default)
4) show cdp neighbors detail (с 2960):

Таким образом, вопрос немного трансформируется: почему show int .. switchport показывает native vlan 1 (с обеих сторон), а CDP уверяет, что на 3560 native vlan 6?
И вообще, у меня с двух сторон access mode, почему его волнует native vlan?
Спасибо заранее!
