Folks,
Here is my scenario. Seems trivial but can't get it to work.
SW1-------SW4-------SW2
SW1 : VTP domain = cisco, Mode = server
SW2 : VTP domain = cisco, Mode = client
SW4 : VTP domain = iewb, Mode = server
The 802.1q trunk links are established b/n the 3 switches and vlan 1 is
native on them.
Changes to vlan in SW1 are NOT propogated to SW2. What could be the problem
?
*SW1:*
interface GigabitEthernet1/0/20
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
*SW4:*
interface GigabitEthernet1/0/14
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
!
interface GigabitEthernet1/0/16
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
*SW2:*
interface GigabitEthernet1/0/19
switchport trunk encapsulation dot1q
switchport mode trunk
switchport nonegotiate
Rack1SW1# sh int trunk
Port Mode Encapsulation Status Native vlan
Gi1/0/20 on 802.1q trunking 1
Rack1SW4# show int trunk
Port Mode Encapsulation Status Native vlan
Gi1/0/14 on 802.1q trunking 1
Gi1/0/16 on 802.1q trunking 1
Rack1SW2# sh int trunk
Port Mode Encapsulation Status Native vlan
Gi1/0/19 on 802.1q trunking 1
