ExtremeWare Enterprise Manager manages Virtual Chassis stacks as aggregated entities.
The Enterprise Manager uses an SNMP identification process to recognize virtual stacks
and their components, based on the known Extreme switches. This information is stored
in the Enterprise Manager database.
The Enterprise Manager can automatically identify single stacks and single parallel
stacks. However, it does not support identification of combined virtual chassis stack
configurations, and identifies such configurations as multiple stacks. Using the Virtual
Chassis Stack Manager you can change the stack configuration representations to reflect
actual single and parallel managed stack configurations. You can also create stack
representations manually, independent of the stack identification process.
Users with Administrator or Manager access can create, modify, and delete VC stacks
and refresh the stack topology identification. Users with Monitor access can view the
VC stack configuration topology and the details about individual components.

DENTIFYING
To create or identify Virtual Chassis stacks, several prerequisites must be met:
• All switches that are to be members of the VC stacks must be included in the
ExtremeWare Enterprise database. If not, the VC stack will be incomplete.
— You must add switches to the switch inventory using the Add Switch function in
the Inventory Manager.
— The newly added switches will appear as Orphan Switches in the VC stack
topology display.
• The appropriate ports on each switch must be properly configured in SummitLink
mode. They must also be configured for load sharing as appropriate.
— This assumes that the switches are cabled correctly as VC stack members.
— Configure the switch ports by selecting the switch in the Orphan Switch list in
the VC Stack Manager Component Tree, and clicking Config to bring up the
Configure Ports in VC Stack dialog box. See "Configuring Virtual Chassis Stack
Ports" for details.
— Reboot the switches.
• Once the ports are configured, you can use the Identify function to identify VC
stacks.
