The switch was running a relatively basic configuration and not under any appreciable load when the crash occurred. It had been running 1.2.5.70 for quite some time and had been restarted several times since the firmware upgrade. I have not been able to reproduce the issue on demand.

I have an sg300-10 unit. I have recently swapped it into my LAN network to replace an aging switch that was exhibiting problems.
The SG300 is reporting near constant 100% cpu load with 11pps input. there are only 3-4 active ports on the switch at a given time. One of those ports does lead to my router and another switch with another half dozen devices.
By itself this doesn't concern me overly much, but I have found that the SG300 is occasionally freezing up for about 20 minutes then restarting. Syslog and SNMP traps don't appear to provide any hints as to what is going on.
I have tied my switch into my monitoring system (packettrap MSP, so if there is something I should be watching that I am not, that would be good to know). I am still troubleshooting getting all the monitoring functions working as well.
So, I have some questions there as well, which OID should I be monitoring for CPU utilization?

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.
Our switch version
switchd64684#show version
SW version 1.1.0.73 ( date 19-Jun-2011 time 18:10:49 )
Boot version 1.0.0.4 ( date 08-Apr-2010 time 16:37:57 )
HW version V01

1) I have a Cisco SG300-28P. I plan to add a SG300-52. Would it be possible to manage the new switch through the SG300-28P web browser ?
2) There are 2 fans in the POE model SG300-28P. How many fans are they in the non POE switch SG300-52 ?

I have SG300-28P that I am using as layer-3 switch. Recently I ran in to SG300-52 switch and even though loading same firmware doesn't give me option to do layer-3 switching. 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?

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.

does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?

Any snmpset commands to add, modify and delete vlan table entries on SG300-10 switches? I checked url... however this information is apparently only valid for catalysts. The latest firmware is installed and the provided MIB files are used.

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?

I'm having alot of trouble trying to connect more that one LAG between two SG300-52 switches.Basically i have configured both switches with the same vlans. 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?

I have a motorola usb modem which is connected to my laptop and i have shared the connection and have an ethernet cable from laptop to wireless modem (TP-LINK) such that other wifi enabled devices can connect to it.Now we have electricity blackouts and when that happens my wireless router gets turned off. Internet on the laptop is working fine, now when the electricity comes back and the wireless router is on, the net does not work on the other wifi devices and only my laptop (as its directly connected to the modem).I have to reboot my laptop for the shared connection to work.

I am unsure whether this is a software or a hardware issue at this point, but 4+ other computers have no issue connecting to the wifi so I am fairly certain the modem / router are working correctly.Basically, I feel like I am playing Russian Roulette with connecting from my laptop. Initially, my laptop connects perfectly fine to the wifi upon boot up, but then it will randomly disconnect and a ! will appear on my taskbar icon. When I open the Network and Sharing Center it will state the it is getting hung up at the "identifying..." process. I will then "troubleshoot" the problem which will take a concerning long time only to return with a couple of different results (I have no idea why these vary). Either it will state that windows can not find a solution and the taskbar icon will turn into what looks like an ethernet plug with a red X on top of it, or the troubleshoot will return with results stating the the "wireless connection adapter and the LAN adapter are disabled" and it will allow me the administrative action of enabling these. Upon re-enabling them, my laptop will again connect completely fine... until the whole cycle repeats itself. And another possible result I get upon troubleshooting is that "the default gateway is not available". Whenever the first or third results occur from troubleshooting the only solution I have found is to restart my laptop (upon which the ABOVE issue occurs) and try again to connect upon reboot.
Here some pictures of the troubleshooting results:
Initial results I receive after directly plugging into the ethernet cable:
Results of troubleshooting if I choose to "skip this step" and not plug into an ethernet cable:
Upon clicking "Try these repairs as administrator":
I have ran Malwarebytes, MSE, defragmented, and cleaned out all my temp files, so in the slim chance it was some type of virus/cookie/malware then it isn't that.I have attempted a lot of solutions to this problem, including an update of all my drivers (which I found my wireless driver was outdated) but updating the driver did not resolve the issue.

I work in a school department and wanted to hardwire two computers in my class using a workgroup switch. I only had one data port in my class. The tech guy told me the switch could cause the entire network to crash. Is that true? I thought a switch was just a passthrough device.

I have many WiSM WLC's running 7.0.116.0. One WLC was rebooted few days ago but there was no crash file and nothing in logs say why this issue happened.There was a power problem at the same time the WLC rebooted (some switches and PE's was rebooted as well) but if it is a power issue why only one WLC inside the WiSM rebooted and the other WLC is still working fine with no reboot?I have 5 WiSM modules connected to the same 6500 box, only one WLC was rebooted which indicates a crash but no crash file registered for it.Is there anyway I can find the reason why that WLC was rebooted?

I have an E3000 with firnware 1.0.04. A forwarded port is spontaneously changing the IP address assigned to it, but with no change indicated in the singel port forwarding configuration.I have a web server on IP=XXX.XXX.XXX.7, and another device on my LAN with an internal web server at IP= XXX.XXX.XXX.8. The single port forwarding configuration is:
HTTP, external port 80, internal port 80, protocol=TCP, to internal IP address xxx.xxx.xxx.7, enable checked The configuration is saved, and all works well for for hours and/or days and I can use the web host from the intenet as expected. However, after a few days or hours the E3000 suddenly starts sending the http traffic to IP=xxx.xxx.xxx.8 instead of xxx.xxx.xxx.7. When I log in to the router and look at the port forwarding page, it still says it's forwarding the http traffic to xxx.xxx.xx.7 ~ even though all http traffic is being sent to xxx.xxx.xxx.8! I have to reboot the router to get the port forwarding to work properly. If I leave the device at xxx.xxx.xxx.8 powered off, the router seems to work fine for extended periods.
There are no port forwarding services in the router that reference IP=xxx.xxx.xxx.8 , and it does not appear that the port forwarding problem is related to DHCP. All devices on my network have a reserved DHCP address based on their MAC. It does not appear that the spontaneous port forwarding change occurs when when the xxx.xxx.xxx.8 device powers up and gets it's address via DHCP. I have also deleted the xxx.xxx.xxx.8 device from the DHCP reservation table and simply access the device as needed by referencing it's IP, and xxx.xxx.xxx.8 is outside the range of DHCP assigned addresses, and the spontaneous port redirection still occurs once in a while.Is there a known bug where forwarded ports are sent to the wrong IP address?

i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.i have supressed this port mirroring.when i try to reconfigure a port mirroring from port FE17 to FE3. The SF200 web interface crash. the SF200 seems to reboot.
i have updated the SF200 firmware from V1.1.2.0 to V1.1.2.9.44 when i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.But after having suppressed this port mirroring again, i was not able to reconfigure a new port mirroring from port FE1 to FE3 (the SF200 hangs).
i have also tried to return to default factory setting but this does not solve the issue.i am working on SF200-24P

I have a question, does the SG300-28 support VTP and STP?. I want to add it to my network's VTP domain so I don't have to manage vlans manually on the SG300-28 and also be able to configure STP to keep my network loop free.

On my SG300 I set up LAG for the last two ports.
I then plugged them into my SRW224G4P, once I do that I get dropped packets.
I was thinking maybe doing firmware upgrades to both switches?

We purchased a SG300-52 last week to replace a 5yr old Dlink which has worked perfectly. 1 day after the SG300 went it it started crashing with this fatal error problem so I reverted the firmware back from 1.2.7.76 (latest) to 1.1.2.0 but I still get the problems. It crashes when I have it on my lan with users connected or if I just have the switch on my desk with just my laptop connected, so it cant be a load issue or a network topology issue. I already have a Cisco SGE2010 on my network without problems.

I have a question about ACL and binding. I have a SG300 28P and a couple of other linksys switches and Access points that are connected to it via trunks. The cisco SG300 28P is running in layer3 mode and i have created a couple of vlans and one of them is a guest vlan. Now to my question, i create an ACL and an ACE that vill funktion so that guest vlan only can connect to the internet and not the rest of the internal network. And then i must bound the ACL to an interface port or lag, what i can see it is not possible to bind it to an vlan? so if i have a port on some of the other switches that is member of the guest vlan, vill the ACL on the SG 300 stop guest vlan trafic to the internal network that is comming from some of the other switches?

I want to set up a vlan only for the wifi APs and wifi clients on my network. They can't access to any server, only internet acces. I already implement this configuration and its working, but now I want to allowed a couple of laptops to connect to servers in other vlan. what should I do? Should I do it using Mac address of laptops or IP?

Yesterday I upgraded my SG300-10P to firmware 1.2.7.76. I was curious about the new SYN Protection feature, but it seems to do nothing on my installation.
The switch is running in Layer 2 mode. I have ACLs in place and DoS prevention is not enabled. I also tried clearing ACLs and enabling DoS prevention. As I understood the Admin Guide enabling DoS in the Security Suite Settings is not necessary for using the SYN Protection.
In my firewall I see about 300 pps with SYN flags only arriving. What "they" do is sending me SYN packest to port 80 from forged IPs, so that my system should send SYN-ACKs to the victim system. In this case it is the Arab Bank. They are down at the moment...I think that is called a spoofed SYN flood attack.
So I thougt the SYN Protection feature should exactly solve that problem but it does not and does not show any "Last Attack" entries.
If I put a SYN filter in place it works, even if I put SYN Rate Protection in place. But that is just a dirty workaround. My firewall blocks those SYN packets with a SNORT rule.

I am using a couple cisco sg300 28P switches along with a sonciwall firewall/router. The sonicwall was already in place and working so they didnt want to replace it. I understand how to configure the vlan on the sonicwall, but could use some info on the cisco. I would basically like to create 3 vlans, 1 default for management, 2 for pc's on lan, and 3 for the cisco spa504g phones/'voip. Would i just go into the vlan managment, configure the 2 new vlans and give them two id's? These offices have one network drop, so the phones and pc's will be sharing the switch ports, however the phones have a setting to configure the vlan id so they know which one theyre on. Is there anything i need to do after that? I want to make sure that vlan 3 has the highest priority becuase its voice, is there some qos configurations i need to make on that switch as well? Also, the port that links the two cisco swtiches together, does that need to be set as "trunk" port? I understand what vlans are, but its just the first time ive run into these cisco models. .

I bought the SG300-10 Switch a few days ago and updated it to firmware 1.3.0.59, but i think there's a bug in this firmware. If I go to "IP Configuration" IPv4 Routes" in L3 Mode nothing is displayed. In the log file i see that:
