Vs SF300-24 L2 L3 Modes
24 / SF300, what is the major difference between L2 and L3 Modes.
The switch, to which you refer is both layer 2 and layer 3 active. If it is enabled, this means that the switch can perform
functions at the level of the selected layer. An active layer 3 switch essentially acts as a router, while the
an active layer 2 switch does not work. Layer 2 switches receive packets and transfer them to the correct in location
a network. Layer 3 switches and routers both do the same thing, but use IP addresses in the packets forwards, between or within networks.
See the next page for more information on the subject:
http://www.Cisco.com/Web/about/ac123/ac147/archived_issues/ipj_1-2/switch_evolution.html
If you have any other questions, I'll be happy to help you.

Routing problem mode SF300 - 24 Layer 3
Hi all, as a topic, I have a problem with my itinerary SF300-24. This is my network configuration:
Port 1 to 12 assigned to VLAN 10
Port 13-23 assigned to VLAN 20
24 port has an IP 10.17.7.254 to connect with my itinerary deafult, because I also have a Linksys RV042 router, connected in turn with my ISP router, having a 10.17.7.1 ip address.
VLAN 10 has 10.17.10.1
VLAN 20 was 10.17.20.1
So I add a default route on my SF300-24 to 10.17.7.1 to get an Internet connection.
Here's the problem:
Computer A is connected to VLAN 10 on port 1
Compuer B is connected to the VLAN 20 13 IDE oucederomsurlesecondport
An e B can talk perfectly each other and also to port 24 (10.17.7.254), but when I try to ping my Linksys RV042 (10.17.7.1) or reach Internet all fail.
Instead when I logged in SF300-24 and try to ping Linksys RV042 (10.17.7.1) or Internet access, everything works great!
What could be the problem?
Thank you

Hi all
below, that's what I do with the SF300 switch:
I joined a cisco SF300 switch to support failover between GPRS and 3G netwoks between two different sites.
To simulate the installation in our platform, I put the cisco SF300 linked to three computers to simulate 3G, GPRS and internal connections. could you please provide a procedure to begin this work.
NB: I start with a simple configuration; create 3 vlans so I did the road ip between VLANs, that the problem is with ip route that's not possible to ping from one vlan to another, I did the same job with the cisco catalyst and it works but with the SF300 I don't know what the problem is exactly.
Could you please help with that?
Kind regards

Hello
Is the main request in this post to establish connectivity L3?
If so, as stated above, configure the switch to be in router mode.
Configure IP addresses on the interfaces of the three VLANs. If sure them VLANS are rising (trunk port or smart host). Check that you have IP connectivity to the switch virtual interfaces. If the switch is the default gateway for the devices on each VLAN, you have basic connectivity VLAN in the VLAN.
See the post below for more details:

Need help with configuration of VLAN SF300-24
Hello
Let me Preface this with the fact that networking is certainly not my point hard, so here, any help is greatly appreciated.
I'm trying to segment on a virtual desktop on its own VIRTUAL local network infrastructure using a Cisco SF300-24 Layer 3 switch. I can get the switch to connect to the network with the assigned VLAN 1 an IP address on the subnet of the network (192.168.16.X), but I can't get anything this is set up VLAN 20 (192.168.20.X subnet) to connect past the VLAN 20 (192.168.20.254) gateway IP. The ports assigned to 20 VLAN are defined to access the mode if it matters.
Here is a diagram to illustrate what it looks like, as there is another (L2) switch involved.
So I'm not really sure what I am missing here since all settings seem simple enough.
Hi Simon, I recommend you remove any server active directory and essentially remove all safety factors. This will give the idea of where to start.
If you take a quite basic set, 2 Windows 7 workstations without a Firewall window activated, they both work as expected.
It must be remembered that in firewalls, even if they are able to respond to ICMP if the request is from a different subnet, they will not be because he is recognized as a network abroad. You must know the network on these computers or make sure the computer does not care.
You may be able to do this by simply adding additional subnets on the advanced configuration of the network card (if it does not take too much address space) as an example.
Or well, as you have discovered that you can add routes, which is a bit heavy and inconvienent, but effective.

I have a SF300 mode layer 3 interVLAN routing with four other SF300s in mode layer 2.
In my syslog, I noticed many errors of ARP Table overflow. We have wooded with over 300 knots somewhere that does not surprise me to see some overflow of ARP table but not at the rate I am actually receive.
I should set the agreesivly age the CAM table aging time? Setting the time for a shorter duration will cause a potential ARP storm?
Hi Carrick, your comments are accurate. Much of the firmware updates are not well and it was generally a best practice to factory default of the switch after the updates.
I've always felt lost switches something after the 1.1.2.0 release as far as performance goes even with excellent features improvements that came after.
SX500X switches are probably about the same price as a switch 3750 in some markets. Even if it was an additional amount of $500 per switch the 3750's would be a better choice as long as you can also offer contracts. SB switches are growing a lot and they are a very good product, especially at the price point. The guarantee is fabulous and the support is good.
I don't think the SB switches are still in position to be a central switch, certainly access or switch of the light distribution, they are more than perfect in most scenarios.
Personally if you have a choice, I would not be surprised if you backward to 1.1.2.0 and missed the switch more or observe all the warnings of performance you would disappear. Personally, he was my most favorite release.

I have a question since last 2 on sf300.
The problem is that sf300 isn't compatible full dhcp, so I put the different internet modem.
I plugged an internet modem in vlan 1 kind of this vlan, users can access the internet and default gateway is nothing else than the Internet modem ip. user in vlan are not communicate with other vlan because other users of vlan default gateway is the ip address of the Interface. How can I give access to vlan 1 to access the other vlan.
See attachment.
I used a static route in any one or all 3 devices.
Thank you
Hi Sir, the switch cannot perform NAT functions, so only the vlan connection to the modem can work this way. The default gateway of the connecting servers must be that of the SVI switch while operating mode layer 3. The modem would require the static routes (not the switch) If you want as virtual LANs to internet connection and intervlan communication.

SF300 Questions of the of the VLAN IP address
I bought 3 SF300-48 switches to work AP1131AG Aironet wireless with my APs. I have now spent 1 VLAN for all to have a Guest_Wireless VLAN 200 as well as the default VLAN 1 for my Corporate_Network. The question that I have is that any client on my default VLAN receives an IP address from the DHCP Windows Server without problems, but when you connect to the guest VLAN you can't obtain an IP address.
So, I also have a Cisco 3560 G Router (default gateway) which has the same Aironet AP1131AG AP connected to it with the same config as additional points of access files and it works perfectly. I can connect to each SSID wireless (Corp. Vlan1 or comments Vlan 200) and get the IP address of the DHCP server.
I also have the network below plan and was seeking help in the SF300 configuration to allow the IP to get on the subnet, Vlan 200. I also tried to connect my laptop directly in the SF300 and configure the port to access the Vlan 200 and I still can't an IP address.
Any help would be appreciated...
Aaron
Hi aaron, on the 3560, the port mode is defined as the encapsulation dot1q and one vlan specified native? Also, for the SF300 vlan natif native is 1, you tag vlan 200 to the trunk?
The Catalyst switch works differently than the SX300 switch in this sense.
Note also, will not attend the VTP SX300 or PAO.

Hi Scott,.
Your only sends me a part of the story, but we move forward another step and add a static route to the WAN router...
A network diagram, even done with paint would be fantastic to understand the topology of your network.
So no history full of how the network is set up, I have to work on assumptions.
PC in the 10.1.32.0 network used the WAN router as the default gateway. You put the default gateway address of VLAN1 and VLAN2, IP switches, according to which VLAN the PC is.
I would like to work on the assumption that the address IP of VLAN1 to the SF300 switch is 10.1.32.100
step 1. Put the PC in VLAN1 back if its default gateway is 10.1.32.1.
step 2. Add a static route that is appropriate in your WAN router so that it knows how to send traffic to VLAN2
It could be something like, and I'll cite the statement of the itinerary which must reside in your WAN router.
To get to 10.20.32.0 network with a mask of 255.255.255.0 Gateway 10.1.32.100 (IP address of vlan1 on the SF300.)
This should then hosts of PC in VLAN1 and the router to learn how to get traffic to VLAN2. the router will redirect traffic to the switch SF300 and he has a way to interface to VLAN2, so he certainly knows how to get to VLAN2 IP packets.
If the WAN router knows where VLAN2, go via the SF300 switch, then he might be able to the Internet of NAT traffic then this second VIRTUAL local network.
We are not finished here, more is yet to happen, such as the DNS and DHCP resolution for hosts in VLAN2 and possible NAT problems according to the capabilities of your WAN router.

Settings of VoIp for the replacement of a Cisco 3550 button with a SF300 - 24 p
I add the SF300 - 24 p to an existing set of switches. My spine is a 3560.
The 3550 I'm replacing has this config for each port that supports a Shoretel phone
switchport trunk encapsulation dot1q
switchport mode trunk
MLS qos trust dscp
include global parameters
pvst mode Spaning tree
spanning tree extend id-system
VLAN spanning tree 1 200 priority 28762
internal allocation policy of VLAN ascendant
all other settings are default
Any ideas how to reproduce it on this new switch? I added the Shoretel mac address range (00-10-49) in phone YES program. The phone is supplied with power, I think he gets a 192.168.6.x address (local subnet), but then he should get a 10.6.0.xx on his IP VLAN - but it doesn't.
Some configs of the spine are attached. I don't have to configure it in the 3550.
Any ideas?
Fred
Hi fred,.
Backup on my PC should be the same as the screenshot taken on my SG300 - 28 p as shown below.

Let me know how it works. I don't really have multiples of the same switch to try it.

Preview.app stuck on the first page of the PDF in single page mode
I regularly Preview.app view PDF files and want to use the "Single Page" function to display an entire page at one time. I have 'Single Page' display set as the default behavior.
Lately when I open a PDF file, they properly open the first page, but I am unable to navigate to another page via the drop-down page, touch up/down arrow. If the PDF file has a table of contents, I am able to go beyond the first page through it and then proceed to navigate normally. If it is not a table of contents, the only solution is to continuous scrolling mode and continue to navigate beyond the first page.
It's very annoying! Unfortunately, I can't remember where this started happening. It could be when I upgraded to MacOS Sierra, but I can't confirm.
Everyone else see this behavior?
Hold down the Option/ALT key, then use the cursor to the TOP or to the BOTTOM of the key.

Activate App stuck on waiting and power Mode low does ' t
Hi all
I have at least two concurrent problems with my iPhone 6 + iOS 10.0.2 (but started with iOS 9).
I can't install new application directly from the App Store on the phone because they were stuck in the phase of "pending". Same behavior of update of the applications that are already installed.
The only way to update/install the app's iTunes download and synchronize.
The other simultaneous problem is in what regards the activation of "low power mode" with the rocker switch (settings > farm > Low Power). Whenever I try to activate (manual or automatic 20% of battery) function, the gray toggle becoming in the Middle, then return to the OFF position.
I already have backupped & restored several times, but nothing has changed.
How can I solve this?
Thank your
Best regards
Hello Axoduss,
Thanks for posting in the communities of Support from Apple. I see that you have two problems. One is that the low power Mode is not activated, and the other is that updates and new applications are blocked pending. I know that I rely on my iPhone for everything. It is important to ensure that it works as expected. I'll be more than happy to help.
Great job to the backup of your phone and restore. It's a great way to help solve these issues.
If you are restoring from a backup, the problem may be in the back upward. I recommend to reset the phone to factory settings and set up like new to see if the Mode low power and installing apps works. If this does not work after the installation in the new and not after the restoration then you want to restore your data manually and not market back. Here is an article on setting up the phone as new:
