VLAN-Definition

VLANs are logical subgroups within a Local Area Network (LAN), which combine user stations, and network devices into a single unit, regardless of the physical LAN segment to which they are attached. VLANs allow network traffic to flow more efficiently within subgroups. VLANs use software to reduce the amount of time it takes for network changes, additions, and moves to be implemented.

Notes when setting-up VLANs

• A VLAN does not have a minimum number of port
• VLANs work at the OSI Layer 2
• A VLAN can be created per unit, device or via logical connection/combination
• Broadcast and Multicast traffic is transmitted only in the VLAN in which traffic is generated.
• To allow traffic between VLAN a device working at protocol level (Layer 3) is required

NETGEAR DGFV338 Primary LAN

The Primary LAN settings can be defined on the GUI of the DGFV338 (Network Configuration, LAN Setup).
If DHCP is required ensure that the correct Starting IP address and Ending IP address are configured including the DNSs settings.

DGFV338 Secondary VLAN

In order to add a Secondary LAN to the DGFV338 the Multi-homing option should be used. This can be accessed via the GUI (Network configuration, LAN Setup, Multi-Homing).

PCs with an IP address within this range will need the IP address, Default Gateway and DNS servers (if different from the Default Gateway) manually set.

Here are some questions of Netgear Smart Gigabit Ethernet Switches.

1. How many units can be stacked together?

A stack consists of up to six Netgear GS700TPS and GS700TS series (GS724TS, GS724TPS, GS748TS and GS748TPS) switches, with support of up to 288 ports. One of the units acts as a stack master, while all other units act as slaves.

2.Can I combine different models in the same stack?

Yes, you can stack any of the Gigabit Smart Stackable Switches (GS724TS, GS748TS, GS724TPS, and GS748TPS) together in a single stack.

3.Can I combine other NETGEAR ProSafe stacking switches into a Stackable Smart Switch stack?

No, NETGEAR ProSafe stacking switches will only stack with members of that stacking family. The Gigabit Stackable Smart Switches stack together, the FS700TS switches stack together, as do the FSM700S switches and the FSM7300S switches, but the four families of switches cannot stack with each other.

4.What does Stack ID mean?

Stack ID is the number (1 to 6) shown on the 7-segment LED display of the front panel. It is used to uniquely identify a unit in the stack, especially for configuration. The Stack ID of the master unit can only be 1 or 2. If a slave unit has a Stack ID of 1 or 2, it is being designated as the backup unit for the stack master in case of failure.

5.What is the main difference between NETGEAR GS724TPS and GS748TPS?

a. The main is difference is number of Gigabit Ethernet ports.

b. GS724TPS is a 24-port Power over Ethernet (PoE) Smart Switch. Port 21, 22, 23 and 24 can also support 100(100base-SX/LX)/1000M SFP.

c. GS748TPS is a 48-port Power over Ethernet (PoE) Smart Switch. Port 45, 46, 47, and 48 can also support 100(100base-SX/LX)/1000M SFP.

6.How many Watts of power are available for Power over Ethernet (PoE)?

195 Watts are available for GS724TPS.

384 Watts are available for GS748TPS.

7.What is the main difference between IEEE 802.3af standard and 802.3at draft standard?

802.3af specifies that the maximum allowed output power of Power Sourcing Equipment (PSE) is 15.40 W; whereas the output power for 802.3at is at least 24 W per 802.3at task force draft 3.0.

8.What if the available power for PoE was used up?

If the connected Power Devices has consumed the PoE power so that the remaining available power is less than 20W, GS700TPS will not deliver power to any further connected Power Devices in order to provide a reserve of power for the currently attached devices. If the current power devices have an increase in power, the NETGEAR GS700TPS will be able to supply more. The PoE MAX LED on the front panel will not be lit until there is less than 7W available from the whole system.

9.What devices can I power with NETGEAR GS700TPS?

The GS700TPS complies with the IEEE 802.3af standard and will power any device such as Wireless AP, IP phones and IP camera that meets that standard. For example, NETGEAR makes two wireless access points that are standard compliant and can be powered by the GS700TPS, the ProSafe WG102, WG302 and WAG102.

10.What modules can I use with the NETGEAR GS700TPS?

The SFP GBIC slot on the GS700TPS can accept any SFP GIBC that complies with the specification. NETGEAR offers two SFP GBIC modules: the AGM731F for multimode fiber and the AGM732F single mode fiber.

If you are experiencing boot problems and TFTP Boot Recovery process cannot be performed, you can use the USB Boot Recovery instead. You’ll need to download the latest USB boot recovery image: RAIDiator-4.1.7 write that image to the USB flash device. To write the image on a Windows PC, you’ll need to use Rawrite32.zip. Make sure to click the Eject button after the write is complete. On Macs and Linux systems, you can see here:http://www.readynas.com/forum/viewtopic.php?p=106668#p106668.

Power down the ReadyNAS, insert the USB flash device, and depress the power button on the front for approximately 20 secs – you’ll see all the disk LEDs blink once at 5 secs, 10 secs, 15 secs, and 20 secs. Release the button right after the 4th blink. This will start the USB boot recovery process. Once the fan and the lights shut off and the lcd screen displays “Attemp”, press the power button and the unit will boot up normally.

Note: ReadyNAS boot loader does not support USB flash drives with USB hub built-in, if RAIDar does not detect NAS after 5 minutes, please try other brand/model USB flash drives or you can check if the flash drive has built-in hub using Windows device manager.

Note: The USB boot recovery method is only recommended for Sparc systems. Do not attempt this on x86 systems unless advised to do so by Technical Support. Unnecessary use of this can cause problems.

Use the boot menu to restart or troubleshoot your Netgear ReadyNAS unit. Your unit has the following boot modes:

1.Normal. Initiates a normal boot process, just like booting using the Power button.

2.Factory default. Initiates a short disk test that takes approximately 5 minutes, then begins a 10-minute time-out period waiting for RAIDar. During the 10-minute time-out period, the system can be powered off safely without causing any data loss. After 10 minutes, or if you select the factory default option with RAIDar during the time-out period, the factory default process begins. WARNING! The factory default reboot process resets the unit to factory settings, erases all data, resets all defaults, and reformats the disk to X-RAID2.

3.OS Re-install. Reinstalls the firmware from the internal flash to the disks. Use the OS reinstall boot mode when the system crashes and corrupts some configuration files. OS reinstall boot mode also resets some settings on your unit, such as Internet protocol settings and the administrator password, to defaults.

4.Tech support. Boots into a low-level diagnostic mode. Use the tech support boot mode only when instructed to do so by a NETGEAR Technical Support representative.

5.Skip volume check. After a system crash, the system tries to scan and fix the volume using a file system check. If several problems are found on a disk, this process can stall, causing the system not to boot. Use this option to skip the scan and let the system boot. WARNING! Use the skip volume check boot mode only when instructed to do so by a NETGEAR Technical Support representative, otherwise data loss might occur.

6.Memory test. Performs a memory test. The pass or fail result is reported using the unit’s LEDs. Contact a NETGEAR technical support representative to interpret memory test results.

7.Disk test. Performs an offline full disk test. This can take 4 hours or more, depending on the size of your disks. Any problems are reported in the RAIDar discovery tool.

The NETGEAR ReadyNAS Community started back in 2004 when we first brought our community forum online.  We then introduced the ReadyNAS Wiki which provided a wealth of information, so much so we found that it became a little hard to maintain.  So in early 2008,www.readynas.com was started. We took a slightly different angle, condensing a lot of the information we’ve gathered throughout the years and news articles to help you understand the ReadyNAS quickly and efficiently and be in tune with what’s going on in the ReadyNAS World. This site focuses on giving you timely information quickly and we’ve chosen to keep the same informal feel as our beloved forum. We hope you will enjoy our somewhat quirky writing style and find the information here helpful.
