I have a situation where i am installing SGE2000Ps to replace my old switches and configuring VLANS. The time clock will not communicate across the VLANS. If I unplug the network cable and plug it back in I will get two successful pings. If i use a PC configured with the same network settings as the time clock and plug it into the port for the time clock it communicates fine.
View 9 RepliesI'm new to the Cisco forums and new to Cisco switches. We just purchased 3 new SGE2010P's and 2 SGE2000P's last week and delivered on Monday.It basically boils down to this. After configuring the system time and hitting Apply and the saving the Running config to the Boot Config and then Restarting the switch the time and date do not remain configured. It other settings but not the date and time.

I have a Belkin wireless router attached to my cable router. I have updated the system clock via the internet on the desktop and checked the time setting in BIOS. These seem to match. I have googled around on this and can't find any accounts similar. My son's Vista laptop and the Win7 laptop have seen each other since day one. The laptop and desktop did see each other at one time, but the connection was lost after I went to a hotel and changed public network settings temporarily. I can ping the desktop from the laptop, but it times out when pinging the laptop from the desktop. I'm running an avast firewall on both, but can't see a problem there.

I have 4 VLANs, and I want VLANs 1, 2, 3 to communciate freely, but I DONT want VLAN 4 to communicate with anybody, just Internet access. On the WRVS4400N, I was able to do this using the Firewall > IP Based ACL. I notcied that the RV180W, does not have such an option. I am sure there is something I am missing, I just cant find out how to isolate VLAN 4.

View 1 Replies View RelatedMy friend and I bought Acer Aspire 5741's about 9 months ago and neither of us has had any problems until now. My friend went to connect to the internet via wireless router yesterday to find that there was limited connectivity (no internet access). We assumed it was a router issue and I gave her a number of things to check but all seemed ok with it. I went to her house to look at it today and when I ran the connection troubleshooter got "windows can't communicate with.......... (DNS server)". I connected my laptop via her router and everything was fine. I brought her laptop back to my house and tried to connect to the internet via my router and got exactly the same 'DNS' message - my laptop again connected without any problem.
I have re-booted the routers, laptops, network adapters etc and also checked the wireless adapter settings on both laptops, which appear to be the same. I have re-set the TCP/IP stack and have also tried ipconfig /release and /renew - none of which seems to have made any difference. the results of the tests are as follows (linksys is the SSID in use):

I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
I was looking for configuring QOS for two VLANS i have created. these will be for voice traffic vlan 22 and video traffic vlan23. i also have three other vlans for pc's, wireless devices and our cnc machines. we have 5 switches that are all SG30028P's with a single switch doing the intervlan routing (operating at layer 3). all of the switches are trunked back to the main switch and ive been through the guide written on how to do this on a single switch which i dont think is layer 3.
View 5 Replies View RelatedI'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 am facing an issue to setup what I initially called simple network but still unable to put it together.On SG300-20 I want to setup 4.3 of the vlan are to separate users in to different groups and to secure data confidentiality.1 is for the NAS. All users on the 3 vlans must access the NAS vlan.All user should have access to internet via SG300 through the ISP provided router. How to configure this, I have every little knowledge of switching and routing? And the routing seems to be the issue I am encountering because I am able to create the VLANs and assign static IP address to them but not able to get them talk to each other. I use each vlan ip as gateway on each port assigned. [code]

I am trying to set up three vlans across two switches. The switches are Cisco SG200 and SG 300 series. There are 20 devices connected to the two switches including a router for Internet. Among these devices are five wireless access points all hardwired to the LAN. If I understand correctly the first thing I have to do is aggregate the two switches. I ran two cat5 cables to ports 1 and 2 of each switch. As I understand it all I need to do is to create SAG with the two ports on each switch. I think I need to use tagging but I don't really understand how to do this. Once I get the trunking set up correctly I want to create one vlan to which all devices will belong for Internet access. The other two would be for data and VoIP. Do I create vlans with the same name on both switches? When I assign the devices (by port) do I need to enable tagging? Which type of port setting should I use? I am assuming that by including the acess points in the vlans will mean that any wireless device connected to them will have acess to the Internet and the devices in the same vlan.

I have a Nexus 5548 installed (layer 2 device only) with several 10G ports supporting IBM P770 systems and a TSM (Tivoli Storage Manager) system on a single VLAN. All of the Nexus 5548 ports are configured for jumbo frames. I was ask to install a new server on the same VLAN as the others but as 1G port without jumbo frames to allow communications with the TSM server. I'm assuming that the 1G port for this new server without jumbo frames configured on the Nexus 5548 will not be unable to communicate with the TSM server that is on the same VLAN with it's Nexus 5548 10G port configure using jumbo frames.

I am trying to get WOL working across different VLANS on a SG-300-10 Switch in Layer 3 Mode. To achieve this, I've setup an UDP-Relay (GUI menu IP Configuration) for UDP-Port 7 to 255.255.255.255 (this should flood all interfaces with the paket), however, WOL doesn't work across different VLANS.

My ISP is providing me with 1 public IP on a /30 network and 14 public IPs on a /28 network. In this example the 10.0.0.1 is the default gw provided by my ISP and 10.0.0.2 is my SF300-08. If I setup my router to route to 10.0.0.2 as the default gw through the interface between the switch and router, can I configure the static routes in the switch to route further to 10.0.0.1?
is it possible to have these 2 networks on different VLANs and configure inter-VLAN routing? I don't want the switch accessible from the 10.0.0.2 IP.
I am IT teacher at a middle school in Nuremberg, Germany. We have in our school 5 VLANs, 4 Switchtes, 1 L3 switch and 1 router.
2 months ago the old L3 switch (Catalyst 3550-12T) is broken. In the short term I've borrowed a Catalyst 3750G-24, so that the network continues to function. Now a SG 300-10 switch was purchased. This should be configured the same as the 3550-12T or 3750-24G.The network looks like this (there are much more PCS than in this image):
VLAN ID
VLAN Interface
DHCP
DHCP-pool
[Code]....
The DHCP server in VLAN 30 is also a FOG server. The Fog server images all PCs in school. PCs in VLAN 10, 20 and 30 boot from PXE. The MS Server in VLAN 10 has been configured by the DHCP options 66 and 67.
The Catalyst 3750G-24 routes the multicast, but the SG 300-10 I do not have the option of using the commands ip multicast-routing distributedip pim sparse-dense-modeto work and must configure igmp. I'm having problems with the igmp-configuration on the SG 300-10. Therefore, I have uploaded the configuration of the 3750G-24 and the configuration of the SG 300-10 (without ACL).
I am having problems accomplishing these tasks with my new SG 200-18.
I have a LinkSys WRT54G2 connected to port 1. I would like ports 2-8 to be in one VLAN with access to the Internet and to be able to share their printers, hard drives, etc. with other computers on ports 2-8. I would like each of ports 9-16 to be on a separate VLAN with access only to the Internet and no other ports on the switch. I would like to be able to manage the switch from any of the ports 2-8.
After I create the VLAN 1009 (see screenshot below), port 9 can browse the Internet and cannot see the other ports on the switch which is correct. However, ports 2-8 can no longer access the switch at 192.168.1.20 in order to manage the switch.
I am a novice at setting up Cisco routers, I have a few years of networking form the server side of things just beginning to work on the switch side. I am trying to configure a sg200-8 to have three VLANs.

View 1 Replies View RelatedI have successfully set up a VLAN on my primary switch which is an SGE2010. I have 3 other switches is other buildings connected in series. The next in line is another SGE2010 and then a SLM2024 and an SGE2010. Each are connected with Fiber and I'm not sure how to set up the switches so that the router controlling VLAN 2 will push IP addresses to the clients on that VLAN and allow internet access. We're using it as a guest VLAN for our customers to have internet access. I have those GBIC ports set up as trunks right now except for the SLM2024...I'm not quite sure how to set that up. The VLAN is set up on each switch exactly the same though.
