I bought 3 switches (gs 300-28 ports)and i need to connect them to my network, when all the switches are cisco 3560g, with vtp on the vlans.my question is, how to creat vlans on this switch? and Is it possible to make the gs300 learn the vlans on the 3560g?if he dosent has the vtp client?
View 1 RepliesWe had a number of Linksys SRW2048 / SRW2024 switches that had the "bloated capacitor issue" or "bad capacitor issue".These units would basically disconnect/connect their ports.Applications would sometimes crash on workstations.These were all located at different client sites.These were replaced under warranty with the SG300-52 units.When we implemented the SG300-52 units at several sites we noticed the the logs showed disconnect/ connects.We were not seeing apps crash.Support advised they were not aware of any issues.We did a firmware update that was available that made no difference. (1.1.0.73)6 months have now passed.
We noticed at our site very poor throughput one night doing a very heavy file copy data transfer between two computers.It actually ground all other computers on the network to a halt.We inspected the switch.It had "all lights flashing".We thought this strange and shutdown the whole system. Problem still existed.Power cycled the switch. Problem still existed.Noticed their was a new firmware update. (1.1.2.0)We implemented this.The lights on the switch stopped "all lights flashing".Throughput was back to normal. (ie didnt grind all other computers to a halt)
We then had a second site complain of similar issues.Heavy throughput between two computers bought all other computers to a grinding halt.Lights were "all flashing" on switch.Workstation would disconnect/connect in a loop during heavy file copy.We implemented the firmware update thinking this would solve the issue.It now still has the issue of disconnect/connect however and apps sometime crash.We have now replaced the switch with a HP 2510-48G.This is working properly.I have now since been to other sites that also have these SG300 switches and notice the "all flashing lights".
I looking to buy SGE 2010 swith, but I have some question:
1. Can I use 4 SFP ports and stack of two switches at the same time.
2. Is it possible to use for stacking ports other than 24, 48?
3. What is maximum possible number of ports to use for stacking (can I get more than 1Gb thruput).
i am deploying some SG 300's to some remote sites and will have static IP's assigned to them. the elements that will be plugged into the SG 300's ports will be DHCP. Is there a way to find out what IP's are assigned by port? Either by the Web GUI, the console, a log, etc?

Code...
How does the ESW 500 or SF300 line guarantee QoS of voice traffic when trunking switch to switch? I have (2) ESW 500 series switches in series. The phone on switch 1 have no audio issues, but the phones on switch 2 (the last in the series) have intermittent voice quality issues when dialing across a WAN circuit to another office. The phone on switch 1 do not have that issue though they traverse the same circuit. They are all using the same VLAN 100.

View 2 Replies View RelatedI just recently purchased an SG300 10 port switch. After reading through many of the threads here, I was finally able to get the different VLANs to route properly. However, I'm having a unique issue that I'm not sure if it's related to the switch or not. I currently have 2 VLANs configured on the switch.ports 1-4 are native vlan 1 (192.168.1.X) ports 5-7 are VLAN 10 192.168.10.X (Trunk Port with VLAN 1 tagged and VLAN 10 untagged)I have a Hyper-V server connected to both of these networks. The VMs are running on both VLANs on port 5. I have the following problem:When I have a domain controller VM on VLAN 10, I notice that many of the DC communications failed. I took a network trace and noticed that many of the RPC port ranges were failing. I am able to ping all of the hosts on VLAN1 and vice versa. My question is as follows:Does this switch have some type of security option that blocks high range ports? I can't seem to find the menu option indicating that this is the case. I have already set-up a NETBIOS UDP proxy, but this hasn't worked much. I still have problems connecting to machines on this VLAN range.

View 1 Replies View RelatedHow do FPS's open UDP ports without needing to configure the router to forward them?I never have to forward ports from my router to my PC. Every game i have somehow manages to open the UDP ports it needs without me having to configure my router. Yet when i check to see if those ports are open (prior to starting the programs) they always come back as blocked or closed. Now I'm currently working on a UDP Internet program and need to know how to do the same thing - open ports on a router without having to make the customer configure their routers. I'm THINKING that other programs start with a TCP/IP connection on the desired port and that opens the UDP port. Is this the answer or is there another method used?

View 3 Replies View RelatedSo, I spent some time this weekend troubleshooting the issues I've had with the new SG300-28P switch and POE to many of my devices in the office. As a recap, I cannot utilize all of the 24 POE ports on the switch for POE purposes. Really only every other port [with a few odd combinations thrown in between]. In addition, the SG300-28P switch, on occasion, is sending POE to non-POE devices [e.g. my Ruckus Zone Director 1106].
Here are my POE devices [all 802.3 af-compliant]: 3 Ruckus 7982 access points1 Pakedge access point2 home-automation controllers2 Polycom voip phones I called Cisco support several times in regards to this problem, and they figured it was a hardware issue - a faulty switch. So, Cisco sent me a replacement SG300-28P, which I hooked up today. The exact problem still occurs. Default configuration [fresh out of the box]. No way I can land, for example, the 3 Ruckus 7982 AP's on ports 1, 2, and 3 [or ports 1,13, and 2]. I have to put them on ports 1, 3, and 5 in order for them to power up. In addition, I can't plug any other POE devices on the ports either between or below them. I had to skip another port bay. This is very odd behavior!! Two Cisco SG300-28P's in a row with the same problem.
However, I also had one of the new Cisco SG300-10P switches in my possession for a recent project of ours. I decided to hook up the same POE devices to this switch. ALL POE devices were recognized and worked! No need to skip a port. And it didn't matter what device was plugged in first or not. I am now convinced that it is either a hardware issue [bad power supply/transformer?] inside all of the SG300-28P switches, or a firmware issue.
Both of the SG300-28P switches were running firmware 1.1.2 [the latest on Cisco's website]. So, I decided to install an older firmware version on the SG300-28P switch that I'm returning [installed 1.1.1.8]. Here's what I found out. I could then plug 2 POE devices [e.g. two Ruckus AP's] in adjacent horizontal ports, but not three in a row. In addition, not all adjacent ports. It's funky. For example, I could plug an access point in ports 20 and 21, but not in 21 and 22. No rhyme or reason in how it worked. And I still couldn't plug an access point in adjacent vertical ports [e.g. ports 1 and 13]. BUT...
It's interesting that the same exact switch that would not initially allow 2 horizontally-adjacent POE ports to be utilized WOULD allow 2 horizontally-adjacent POE ports to be utilized when running a different firmware version. It's also interesting to note that when plugged into a "non-working" POE port, the SG300-28P would actually make a small whining noise. Very subtle noise; I could hear it when approx. 1ft away from the switch. The noise was not noticeable when ports were skipped [and POE actually worked]. Therefore, I believe that Cisco has some SG300-28P firmware bugs [at least in the last two versions of firmware] that is not truly allowing all 24 ports to utilize POE correctly. This problem does not exist with the SG300-10P switch.
In addition, I'd like to know when they think a solution could be created if it's firmware-related. If hardware-related, I don't think I'll be recommending any 28P switches in our projects. Perhaps just the regular SG300-28 with a separate SG300-10P. It's a shame because the SG300-28P is more of a bargain when compared to the two separate components.
I have 5 VLANs, I assign VLANs to its ports and make them all Untagged.I created ACLs and a ACE rules for each ACL, and then assigned to the ports.So what i am trying to do is to deny access to from one port to other 4 ports and granted access to any other ports. But it is not working, without last rule "allow any any" it has no access to any ports, with the last rule it grants access to every port even to those I denied.Router in Layer 3 mode, all VLANs have their IP's.
At some moment I was able to work it properly but without using any rules, I just tagged my untagged VLANs to those ports which I wanna get access to. As you can see I want allow ports GE1 - GE4 communicate with 1 to 24 ports but not to each other.
I have 5 VLAN's setup in the sge2010. I have one port (uplink for the network) that I want everyone to see. But have separate VLAN's for different departments as to keep them all separate. Everytime i try and Untag that uplink port, i lose my untag in the original VLAN it was tagged in, and it changes to excluded.
View 13 Replies View RelatedWe are experiencing bridge storms and network slow downs and we believe we have traced the issue down to users plugging a cat 5/6 cable between 2 ports on the wall both wired back to a SGE2010 switch.
So we did a test - we plugged a single short cat 6 cable between 2 ports on a SGE2010, our access switch. Suprisingly, even with STP enabled, the switch DID NOT block one of the ports and in a few minutes the ENTIRE NETWORK was down, as CDP, STP, and ARP traffic became a multi-gigabit storm throughout the network.
Why on earth does this switch not block a port that is obviosly looped?
Every other cisco switch since I started on 1900XL's did this in 1999.
I have a Cisco / Linksys SRW 2016 switch, all was working fine. Powered off and powered back on a day later.Switch powered up and the system light lit.But non of the ports what had cables connected were active....If you connect a network cable to the switch and then a laptop / pc .. The computer knows that there is a connection, but only gives a 169 address. Presumably because the switch cannot get to my dhcp ?I have tried connecting a serial cable to the switch top see if I can see any error, but when running Hyper Terminal I only get the white screen and can not see any POST etc.As far as I under stand it is a straight through cable, do I need a null modem cable to console onto the switch?
