4 Configuration
The stacking software configures each device tables and registers to support
all switching functions, for example, switching, link aggregation, port mon-
itoring, spanning tree protocol, VLAN, etc. The entire stack will appear as a
single IBP.
You find a detailed description about switch stacking in the "PRIMERGY
BX900 Blade Server Systems- Ethernet Connection Blade Module- IBP ver-
sion (User`s Guide)", chapter 6.
VIOM supports uplink sets and networks on switch stacks. An uplink set can
contain uplink ports from different IBPs in a stack. You can see stacks in the
VIOM GUI on the Setup tab if you click on a stack member. Then all
members of this stack are highlighted: the stack master is yellow shaded; all
other members are green shaded. Beside this, Stack Master or Stack
Member is shown in the details area.
To define, modify, or delete uplink sets and networks in a stack, select one
stack member and start the desired operation. Details can be found in "Defin-
ing network paths (LAN)" on page 277.
Using stacked SB11 Connection Blades in IBP Mode
VIOM also supports stacked SB11 connection blades in IBP mode, but the
configured stack must not span over several chassis. (Stacked SB11 con-
nection blades in switch mode are also supported since VIOM handles them
transparently. In this case the stack can span over several chassis.)
For correct handling by VIOM the SNMP agent on the stacked SB11 con-
nection blades must be running and the SNMP community for the SNMP
agent on the stack must be configured to be identical to the SNMP com-
munity of the blade server management blade. If this is not done, ServerView
Operations Manager cannot retrieve the necessary information for VIOM in
order to detect the stack correctly and the stack members might be handled
as single connection blades which will result in errors.
It is important to configure the SB11 IBP stack before managing the chassis
by VIOM. Also the topology of the stack (which connection blades belong to
the stack) should not be changed, while the chassis is managed. If the stack
gets broken while the chassis is managed by VIOM, this is handled as a
stacking error by VIOM. In this case the stack needs to be repaired.
