none — the SmartSwitch 2000 will reserve all bandwidth for switching; therefore, if all the bandwidth is needed for switching, management frames may be dropped.

limited — the management of the SmartSwitch 2000 may appear slow while the SmartSwitch 2000 is at maximum switching load.

full — management of the SmartSwitch 2000 is always possible and management frames will have priority over switched data if full CPU bandwidth is required (switched frames may be dropped).

To configure the CPU Management Reservation:

1.Next to the CPU Management Reservation field click on and select none, full, or limited from the drop down list.

2.Click on the Apply button to set the new CPU management reservation. A window opens stating the set was successful.

802.1Q VLANs

This section introduces and describes pre-standard IEEE 802.1Q port-based Virtual Local Area Network (VLAN) technology and the windows used to configure 802.1Q VLAN-capable devices. SmartSwitch 2000 firmware version

4.00.08supports the pre-standard IEEE 802.1Q draft specification for port-based VLANs.

NOTE

For SmartSwitch 2000 firmware versions 4.00.08 and above, HSIM-F6 modules cannot be installed in a SmartSwitch 2000 that is operating in 802.1Q mode.

What is a VLAN?

A Virtual Local Area Network (VLAN) is a logical group of devices that function as a single Local Area Network segment (broadcast domain). Devices comprising a VLAN may be (physically) widely separated, allowing users located in separate areas or connected to separate ports to belong to a single VLAN group. Users assigned to a VLAN can send and receive broadcast and multicast traffic as though they were all physically connected to a single network segment. VLAN-capable switches isolate broadcast and multicast traffic received from VLAN groups, and contain broadcasts and multicasts from members of a VLAN within that group.
