You manage the bladecenter switch thru the management module on the bladeserver itself . Management does not occur thru the 4 uplinks 17,18,19,20 so it will always be vlan 1 for the management in the bladecenter switch. Just put a port into vlan 20 and connect it to the management port on the bladecenter. All other "server" traffic does indeed flow up thru those 4 ports on the igesm switches.

That is correct if vlan 20 is your mgt. vlan and you want to address the cisco switches in vlan 20 , though it will still be vlan 1 when you look at the config in the switches themselves .

As others are implying, the internal ports, gi0/15 and 0/16 are in effect proxied ports for the IBM blade center MM.

The VLAN number you use, in practice, for management is irrelevant, just as long as you make the SVI the same vlan number you assign those two ports two....and make sure that VLAN number is different than the data plane...

This is covered in gross detail in the IBM IGESM implemenation guide
