36CHAPTER 2: INSTALLING THE VCN ACCESS CONCENTRATOR

If your switch is the SuperStack II 1100 or 3300, connect to the front panel ports. If your switch is not the SuperStack II 1100 or 3300, follow the procedures for your switch.

Mounting the For instructions on mounting and powering-up the SuperStack II Switch Ethernet Switch 1100, see the SuperStack II Switch 1100/3300 User Guide.

If your switch is not a SuperStack II 1100 or 3300, follow the procedures for your switch.

Configuring the Ethernet Switch for the VCN Access Concentrator

This section describes the procedure for configuring the Ethernet switch.

Sequence of Configuration

The following is the sequence of configuration actions:

1Define the desired VLANs, if any, on your switch.

2Define the MAC addresses for all of the 24 VCN AC ports and all APs attached to the AC.

3Connect the VCN AC.

Defining the VLANs after the VCN AC and AP MAC addresses may make some of the addresses inaccessible.

The default VCN AC VLAN for management is VLAN 1 tagged.

If MAC addresses are not defined before the VCN AC is connected, the switch will flood the entire network with the initial messages sent through the VCN AC, since the destination addresses are unknown.

Not more than one VCN AC may be connected to a switch.

The remainder of this section describes the procedure for defining MAC addresses for the VCN AC and VCN APs.

Inserting MAC Addresses for VCN Access Concentrator Ports

Detailed instructions are presented here for both manual and automated procedures for the SuperStack II 1100 and 3300 Ethernet switches.

General guidance is provided for non-SuperStack switches.
