I have a Cisco ESW520 8 port that is connected to a cisco catalyst 3560G.
Our switch management is on VLAN 100 and vlan 1 is the data network.
I have trunked the two switchs and on the interface of the 3560G is as follows:
switchport trunk encapsulation dot1q
switchport trunk native vlan 100
switchport trunk allowed vlan 1,100
switchport mode trunk
ip dhcp snooping trust
On the switch ESW, i have used the smartport macro Switch with native vlan 100 and allowed vlan 1,100 on the gigabit uplink and desktop macro vlan 1 on the other ports.
Now, the native vlan works fine, I can access the ESW switch from the vlan 100 from the 3560G vlan 100.
The problem is that the vlan 1 is not being trunked and I cannot access the vlan 1 at all, from the ESW 520.
I cannot see the issue here.
Thanks for your help,
