Cisco 3750 Vlan UP / Down

[nickgiardelli]

I have 2 3750 switches stacked, I have 5 3560G 48 port POE switches that connect back to the 3750. If I reboot any of the 3560 switches the vlans on the 3750 go up and down.

I have contacted TAC and they switched out the 3750 but the issue still happens.

Here is the 3750 config
