Make sure the L2 vlan is created , use "show vlan" to check . Also check to make sure the device is configured exactly the same on the other end of this switch . I have seen times when you need to take the whole port channel down with a shut on the SVI and then no shut the port channel SVI to sync correctly. Whats on the other end of this port channel ?
As I posted above VLAN is created, does locally configuration on Switch depends on config. of remote end? (I use transparent VTP mode) In this test in both case other SW is Catalyst4948 and I do not add test VLAN999 on this Portchannel.
I can't shut SVI, trunk configuration changes occur as every customer add in my network.
Please paste "show vtp status" and "show int trunk" from all concerened switches i.e output from TEST and as well production environment. Also when u add the vlan to allowed list try shutting the range po with member interfaces and re-enable them together. let me know if that helps.
