Cisco Switches :: LAG Configuration On SG300 52 Switch?

Sep 10, 2011

I am having an issue with LAG configuration on a Cisco SG300 52 switch. I have connected four Ge ports on the switch to the four NICs of a Dell R710 Server on which I installed Windows Server 2008 R2. Without LAG configured, these ports would forward traffic to and from the Dell server fine.However, if I configure LAG on the ports with LACP enabled, then they would not forward any network traffic. Debugging shows that the ports are up but their forwarding status show N/A. Am I missing any configuration? Can I configure LAG on edgeports?

Cisco Switches :: SG300 Correct Configuration For Redundant Link Between Two Switch

Mar 9, 2012

I have two switch SG300-10 that need to be interconnect togheter with a simple redundant "cable fail safe" configuration.My idea is use the two uplink copper port of the first switch, connected to the two uplink copper port of the second switch.

How to create a working setup configuration? The first setup that i need, is with only one VLAN1 for all ports,
 
The second setup is with the VLAN1 assigned to the ports 1-2-3-4 of all the two switch, (linked togheter by uplink ports)
and the VLAN2 assigned to the ports 5-6-7-8 always linked togheter with the same uplink ports.
 
Is possible use the two uplink port at the same time, as cable fail safe? or use a uplink port 1 for the first group and the second uplink port for second group?
 
I need to use this configuration for audio cobranet transport, and i need to test the correct configuration for the primary and secondary audio stream, if can work togheter on the same VLAN or i need to separate the two stream, from start to the end.

Cisco Switches :: SG300-10 VLAN Configuration

Apr 22, 2012

Before I launch into this can I say that I am very much a novice with regards to Managed Switches and their configuration. I have the following equipment which I have connected to the switch: [code] All of the above are on subnet 255.255.255.0.All of the above communicate with each other during normal operation.Our client is connecting to the switch but his requirement is for his system to "see" the PLC Comms Card as follows:IP: 10.0.3.61 on Subnet 255.255.252.0 .
 
Using the Internet Explorer interface connection I have created an additional VLAN (ID 2) on Port 10 with the intention of using this as the connection to the client ( I assume there will be further settings required to route the PLC connection to this port) but every time I try to assign the IP and Subnet values and click "APPLY" the changes are not made and the connection appears to hang leading me to reboot the switch.I have connected to the switch via console and changed the mode to Layer 3.  I also assume that it is OK for the three pieces of equipment to remain on the default VLAN. How I should setup this VLAN and ultimately achieve my goal.

Cisco Switches :: SG300-28 - Configuration As DHCP Server

Aug 28, 2011

I am relatively new the configuring network switches. Could someone point me in right direction to configure SG300-28 as a DHCP server?

From the people I talked based on device specs it should be able to act as dhcp server. However, if we cannot, can it be configured so that clients get DHCP information from Firewall to which L3 switch is connected.

Cisco Switches :: SG300 Can PC Manage Switch And Get Data From It

Oct 12, 2011

Mgmt Vlan 1 (default) Data VLan 10 (with access to internet) Is there a way to have a PC attached to a SG300 switch such that it can both access Vlan 10 for data and Vlan 1 for managment ? The PC's port clearly needs to be untagged PVID on vlan 10. I have tried adding vlan 1T and setting the port as a trunk port but to no avail, The switch is currently level 2. I am guessing this might not be possible in level 2 without setting the mgmt vlan to 10 ?.

Cisco Switches :: Set Up New SG300-52 L3 Switch For Switching And Vlan

Mar 4, 2012

i was trying to set up a new SG300-52 L3 switch for switching and Vlan. The problem is that the vlans on this switch cannot get their DNS resolved. Probably a stupid thing i can't get to see, but i think it is a simple solution given switchin is not my expertise.So my setup:

- ISP Wan router: LAN ip 10.0.0.1, DMZ: 10.0.0.2 -> i have to use this router for ISP support. But it suckes, that's why we use own router for firewall, port forwarding etc.
 
- Nice Router: WAN: 10.0.0.2, LAN: 192.168.1.1
 
- SG300 L3 switch

This works. I can ping switch, nice router, ISP router and google's ip from VLAN 5.But i cannot ping google using host name. From within SG300 i can. So it has something to do with SG300 not doing DNS right.My Client on VLAN 5 has ip 10.1.1.5 / 24, default gateway and dns pointing to switch: 10.1.1.1.I have put an entry in DNS servers in SG300: 192.168.1.1 active (pointing to Nice router). On client leave default gateway pointing to switch. But put DNS server : 192.168.1.1

Cisco Switches :: SG300 Switch - Device Swamped

Oct 10, 2011

I have a recently purchased 28 port SG300 switch. Everything is working well. Unfortunately there is so much traffic flying around that a 10MB half duplex device is struggling to function as it is overloaded. Removing some of the sources of traffic fixes it.

Fortunately I only need to access that device from one PC on the network. That PC however needs to access everything else on the network.

Is there a simple way to shield the slow device from everything except traffic from the PC ?

The switch is in Level2 mode at the moment. Everything is on a single sub net.

Cisco Switches :: SG300 Switch 2 Separate Networks

Sep 1, 2011

We have 2 separate networks here, 1 for data (192.168.0.x) and 1 for VOIP phones (192.168.3.x).
 
I need them to both be connected to different ports on a switch (Cisco SG 300 10 port managed switch) which is then linked to another switch (Cisco Catalyst 2960 48 port switch). Then on this 2960 switch I want the link to be split back into the 2 separate networks. I think that I need to create 2 separate VLANs and assign them to different ports.

Cisco Switches :: Ip Routing Command On SG300 Switch?

Feb 8, 2013

What does "ip routing" do on the CLI on the SG300? When I do this, I see it enables ip forwarding, but there is no mention of this in the CLI manual.  I'm just trying to figure out what I would use this for, and if I should leave it enabled, or disable it. I have several different SG300 switches in L3 mode, and they are set up in a multi-vlan environment...

Cisco Switches :: Routing Between Two Vlans On An SG300 Series Switch

Oct 22, 2011

I've seen lots of posts from people having problems routing traffic between two vlans with some complicated examples.  Any simple step-by-step example for an SG300 switch (in layer 3 mode) to configure two vlans and sending traffic between the two vlans without an external router?
 
-VLAN1 10.10.10.0
-VLAN2 10.10.20.0
 
I've tried to do this through the GUI and can't seem to make it work. I'm missing something in the GUI.

Cisco Switches :: SG300 Stacking And Powered From POE By Upstream Switch?

Sep 11, 2012

I discovered on a pair of SG300-28P.
  
On a second switch (ver 1.2.7.76) when I unplugged the power cord, to my amazement the switch turned right back on (about 1 second later), with the power cord removed. To verify that the power is indeed coming from POE, the upstream switch (ver 1.1.2.0) that is the same model (sg-300-28p), shows all 7 Ethernet ports connecting the two drawing from 2700mW, to 3000mW.
  
While the second switch is powered from the first over POE, the POE does not work on the second switch to power anything, and the system summary mentions something about "PoE Power Information on Master Unit".
 
Is this a stacking operation, and is POE on the second switch NOT supposed to work when powered over Ethernet from an upstream switch?

Cisco Switches :: Getting DHCP Relay To Function Properly On SG300-20 Switch

Dec 5, 2012

I am having some issues with getting DHCP Relay to fuction properly over our SG300-20 Switch.Out current layout is as follows. Hanging off the SG300-20 are a pair of Clustered Checkpoint Gateways with VLAN'ed interfaces in Both of our 2 VLANs, a 3COM 4200G In VLAN1 which has the DHCP server (And all the other Servers) connected to it, and a Pair of HP Procurve 2520's Stacked in VLAN 2 to provide PoE for our Phones/connectivity for our PCs.The problem is I cannot get the DHCP Relay to fuction from VLAN 1 to VLAN 2. If I assign an address in VLAN 2 manually to a device connected to the Procurves, everything works fine. I am able to reach both VLAN 1 and VLAN 2, but DHCP aquisition fails even if the device is connected directly to a port assigned to VLAN 2 on the SG300. The SG300 is running at Layer 3 currently also.
 
Here is a copy of the running config:
--------------------------------------------------------------------------------------------------------------

Cisco Switches :: SG300-28 GUI Different Than Online SG300-48 Simulator

Aug 29, 2011

These are our first switches and seems like GUI is lot different than the online. Out intervlan routing is o not working. I am absolutely sure that I setup the switch in L3 mode since it allows me to create mutiple interfaces. I am hoping that this GUI issue is related to interVLAN routing.
 
Below is the blog I started for InterVlan issue [URL]
 
This is the link for online simulator and what I see in its IP tab. I know this switch is not SG300. [URL]
 
This is what I see on our switch.

For SG-300 I see options in GUI to create vlan interfaces under IP information section, while SG300-52 has IP information option only under the management section.let me know if these are 2 different hardware types and L3 is not possible on SG300-52. If its possible to enable L3 switching on SG300-52?

Cisco Switches :: SG300 Switches Have Poor Performance In Layer 3?

Jan 1, 2013

We have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
 
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each.  Switch was connected to HQ Network as untagged VLAN 101.  I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great.  Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then  Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
 
I then  Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.

Cisco Switches :: Multiple VLANS And SG300-28P Switches Setup?

Aug 20, 2012

I'm going to have several SG300-28P switches to setup.  I'll need to create multiple vlans for data, voice, and wireless traffic.  I have the following questions in setting up this configuration:
 
VLAN 1 Management
VLAN 100 Data
VLAN 200 Wireless
VLAN 300 Voice 
 
1) For managing the switches via IP, will LAN1 be the default management network?  Should I create a seperate VLAN for managing the switches?
 
2) For uplinking the switches together, I plan to trunk a port to connect the switches together.  What's the configuration on the trunk port to forward all vlans from one switch to another?
 
3) On some ports, I want to configure a trunk for two vlans (Data and Voice) where the phone has a pass through for PC.  The phone supports tagging for the PC and the VoIP traffic.  For example on port 10, would VLAN 100 and 300 be set to tagged?

Cisco Switches :: SG300-52 Multiple Lags Between Switches?

For 2 of the vlans i would like to connect them together between the two switches using LAG. Switch1 has Vlan 5 (ports 1-12) & Vlan 10 (Ports 25-36) with LAG configured on ports 1-2 and ports 25-26. I have setup the second switch identical to the first. But when i connect the LAG's there is no connectivty. If i disconnect one LAG the other starts working.Can you only have i interconnect LAG between switches?
