Cisco Switches :: Linksys SGE2000 VLan With VMWare Hosts
Sep 18, 2012
I have a Linksys SGE2000 Switch and I've been trying to get Vlan's to work.How I'm trying to setup is like this
Port 1 - Vlan22 - Plugged into trusted port in firewall
Port 3 - Vlan25 - Plugged into DMZ in firewall
Port 15 - is plugged into a VMWare host. The network is setup as production is Vlan 22, DMZ is Vlan 25.
Port 16 - Internal server so is Vlan 22
Both Vlans have a different IP subnet.I think I have port 3 configured ok as it's only one Vlan. I'm trying to get Port 15 configured properly and it won't work.Servers on VMWare hosts are Windows Server O/S.
I currently am using the SGE2000 switches for our datacentre and they have run great. We are looking at replacing them as part of our normal equipment refresh and have questions about what is the best switch for us. We are looking at upgrading to at least 48 port switches which isn't a huge issue.The main purposes of the switches will be for iSCSI traffic between Starwind SANs and Vsphere 5.1 hosts. We had some latency issues with one of the SGE2000s but otherwise they've been great.
We also will use these switches to handle our feeds from our ISP and our normal interserver communications. We have had DDoS attacks in the past of 40k packets per second and 600mbps and the SGE2000 never even flinched. We don't need it for any layer3 routing (which we use virtualized PFsense for). Looking at the Miercom report the SG200 series looks like it would be fine for us but I'm just worried around the part which mentions it becoame unresponsive in a DoS attack and also whther it may be slower for iSCSI. Both series seem to support flow control and jumbo frames.
I'm having trouble getting a stack of three sge2000 switches to connect together and NOT reboot.Two of the switches are older Linksys sge2000s and they stack well together, but as soon as i connect the new Cisco sge2000, it will make them both reboot sequentially, even though it detects that it needs to be #3 in the stack.SW 1 port 24 is connected to SW 2 port 12 and they function correctly (both of the linksys switches). The documentation states they should be connected in a ring topology so I first tried completing the loop with SW3 (the newer cisco sge2000). When that had the aforementioned troubles I just connected SW2 port 24 to SW3 port 12. Still forcing the switches to reboot.I SUSPECT it may be a firmware/software issue, but I wanted to check if they'ed even work together.
Im planning for a network upgrade.77.110.87.112/28 - is assigned to selected users and configured manually.(note: they are public IP which our ISP assigned)192.168.1.0/24 - is assigned to users that are not allowed to use internet services and configured manually. I have CISCO 1841 Router connected to the internet and CISCO SGE2000-G5 24ports layer 3 switch that is connected to cisco 1841 router.i want to create vlan in layer 3 switch. [code] i want all vlans would still ping to each other and file/printer sharing is available.kindly check if my network upgrade plan is correct, how am i going to configure those vlan in my layer 3 switch and to connect to the internet.
I have a Campus LAN setup which is layed out using Cisco SRW2024 and SGE2000 SB switches. On the LAN we are running various services. These are CCTV, VOIP(SIP), Public Address(multicasting) and Internet hotspots to various locations. I have attached a layout of the setup. A unique VLAN is setup for each of these services.The problem we have is that the PA audio is breaking up at intervals making the output distorted this is also happening for the SIP phones within the facility. Using the user guide we have tried to setup QoS on the system but we seem not to improve the services.
I have a problem with a test network configuration i'm trying to set up. I have an SGE2000 G5 switch for LAN traffic, and i have "reserved" 3 ports with a VLAN to obtain two separate internet lines with two different public IPs from my ISP internet cable. Now what i've tried to do is connecting the ISP cable to the port1 of the VLAN, and i've connected the other 2 ports to my routers. The problem is that when doing this, port1 switches to half-duplex mode and the result is a huge performance degradation (0.28Mb DL instead of 16Mb approx.).
I'm trying to get a network of SGE2000 switches mapped into Cisco network assistant.It always comes back with the device type unknown and status unsupported device.Is there a way to fix this ? I'm using Cisco network assistant ver.5.7(6)
configure a secondary ip address (over the same address range) in a vlan interface on the SGE2000?For example, I want Interface Vlan 10 on mw switch has 172.16.10.1/24 and 172.16.10.2/24. Is that possible? If I try I get an error message with a duplicate IP address error. On Catalyst switches it can be done, but on Small Business?
DHCP Relay on a SGE2000 switch.I have configured two VLANs on the switch, VLAN2 (192.168.10.x/24) and VLAN3 (192.168.9.x/24). I have the switch in Layer 3 mode. I have configured the DHCP relay server of 192.168.10.4 and the DHCP Interfaces as VLAN3. All of the IP Static Routes were generated by the switch.
If I put a client computer on a port that is Untagged VLAN 3 and try to get a DHCP address from the server on an Untagged VLAN 2 port I never get a response back.I have done some packet captures and here is what I have found:
I see the DHCP broadcast on the client computerI see the DHCP Request on the DHCP server coming from the IP assiged to the switch on VLAN 3 (192.168.9.254)I see the DHCP server respond with a DHCP OfferThe DHCP offer never gets to the client computer I can't seem to get a DHCP address to any system not on the same VLAN as the DHCP server. Option 82 is disable and I did try enabling it, which made no difference.
Does the SGE2000 supports NetFlow? I've checked the Cisco docs and also called Cisco support to which no one has been able to answer me.
Anyhow, just in case it doesn't support NetFlow, how to be able to set up something that would be able to check the bandwidth usage on each port?
I've got a problem where I think the SGE2000 switch is failing when I pump around 190~200Mbps through x2 of the ports (Server A on port 1=130Mbps and Server B on port 2=60Mbps) of Multicast traffic (UDP). I can measure the output from the Streaming servers that provide the multicast content, thats how I know the input to the switch and I know that there are no packets lost or any errors departing from the servers, yet when I increase server B to say 80Mbps, I get break up and all sorts of problems on the client end STBs and it is happening on the multicast content provided by Server A too which is a different source, so I'm 99.9% sure its a SGE2000 switch problem which is why I'd like to monitor it somehow.
I´ve got a strange problem with the connectivity within a ring topology.There are five switches from the SGE2000 series and one SG200-50.The SG200-50 is the root bridge and RSTP is configured.From the root bridge switch (Switch 5) I can ping Switch 0.But I cannot ping Switch 0 from PC0.
On the other hand I am able to ping all other Switches (1-5) from PC0.In addition to that I can establish a RDP connection from PC0 to Server0.This tells me that there is no general problem with the connection from PC0 to the Switch0.
Right now when I want to configure Switch0 the only way is to connect to Server0 first.But we have to move Server0 and this is why I want to manage Switch0 from PC0 like any other Switch on that network.
We have a couple of cisco SGE switches connected to a single DELL, between the cisco switches we have a trunk interface. I'm not sure which setting should be configured on the switches to get it working because a loop is occuring.
We have been set the task of securing a small managed office system which is currently set up with a standard switch allowing each of the offices (containing different companies) to see each other, and in some cases, access each others documents across the network.
Obviously this is a far from adequate set up and our aim is to isolate each office using VLAN's but share a common internet connection provided by the managed offices. We have two Cisco SGE2000-G5 layer 3 switches but we are new to Cisco equipment and VLAN's so we are not quite sure on how to implement this. DHCP would need to be provided by a Router, there is no Server. We are open to suggestions on the Router as we have yet to purchase one.
We've been trying to monitor the used bandwidth of our SGE2000 and SGE2010 switches with Nagios.We've been experimenting with the various OIDs and we've found the OIDs linked to the different switchports.
Though when we use SNMPWalk (to find the OIDs connected to the port) the names of the ports are all the same.
[code]....
Is there a way to change the names of these interface to unique names?We've already given unique names in the description field through the switch's GUI, but it doesn't make any difference for Nagios.
We lost connectivity to the web user interface - it no longer responds on the configured IP address.From the manual we see that by default the switch get its IP address via DHCP - but we find no record of any ip address assigned to this switch.Is there a IP address that this unit defaults to when DHCP is not available? Also - what is the best way to connect to the console using Windows 7?
The switch sge2000-g5 a small business switch, has a redundant power supply port built in the switch. It is a port that handles a 12v power supply. My problem is to find the exact device to supply the power to this port so I can have, obviously, a redundant power in my switch. This switch is actually out of production.
We have recently started as Internet service provider in an open metropolitan.
We use a Cisco 3560G Layer 3 switch, where we have all our vlan where we have konfiguerat ex. Switch (config) # interface vlan 150, an interface for each VLAN capabilities such as int vlan 1 - 10/10 int vlan 2 to 30/10, int vlan 3 100/10 and so on. Our int vlan is configured as follows:
dhcp relay information trusted ip address <x.x.x.x> <x.x.x.x> ip helper-address <x.x.x.x> Ports (ex. int Gigabit Ethernet 0/1) are configured as follows: description Uplink switchport access vlan x
[Code].....
Now the problem; we have a customer in ex. vlan 3 who needs to access a server provided by another customer in the same vlan (vlan 3), and access to each other in the same vlan is not possible. You can access the server from any other vlan, but when it comes to access to another host in the same vlan, you will not reach it.
We suspect that the energy company has configured with pvlan isolated. If we use the command ip local-proxy-arp on each vlan, it works to reach each other, but it seems that our 3560 becomes overloaded when ip local-proxy-arp is enabled and it streaming and use IP telephony it doesn't work. The response time at ping is longer and the loss of packets increase with ip local-proxy-arp enabled. The other operators in the metropolitan also uses Cisco 3560G so the hardware should be sufficient.
We have also tried to add no split-horizon, but it made no difference. How do we get around this without negative consequences? Probably need something that makes you allow to send out the same interface that it came from, because it works as long as you are in another vlan.
I've a big problem with a loss of packets ICMP sent by different hosts in differents VLAN. Here my architecture:
Core Switch : 2 Switch's C6509 (Version 15.0 (1) SY1)- Mode VSS - One lien VSL , the other link is defective.Access Switch: C3750 , Connected to Core Switch through 2 fibre optique wires.Topology: redundant ring
When I send consecutive ping message I found always a missing of packets . Furthermore When I insert the "show ip traffic" command., the parameter "bad hop count" increase after a loss of packets. I've 2 hosts connected in my network and they send packets with TTL =127.
In the Core Switch I haven't configured the MEC because it gave me troubles with the packets multicast.
According to Cisco, Nexus 1010 can host up to (6) Virtual Service blades. I can't find out how many Virtual Supervisor Modules and Virtual Ethernet Modules that make up one Nexus 1000v switches can be supported by each Virtual Service Blades. In other words, how many Nexus 1000v switches can be created with Nexus 1010 appliance?how to configure Nexus 1000v switches with vmware. without Nexus 1010, the standalone nexus 1000v switches was configured from vCenter as an OVF. But how to configure Nexus 1000v switches with vmware where nexus switches are hosted on Nexus 1010 appliance.
I have a SG300 Switche working in layer 3 mode.I configured 3 VLANs on the switch, assigned all ports, given IP addresses to VLANs interfaces, etc.Now I want to implement ACL to permit or deny access between vlans and hosts.Can I apply an ACL to a whole VLAN (in or out) like Catalyst models?I mean apply the ACL to the entire vlan or the only way in this model is to implement that ACL port by port?Every time I have a new port configure to work in a Vlan I have to implement the ACL?
I have Linksys SPS224Trying to create VLAN through SNMP. Issueing the string to create VLAN ID=100 with name "VLAN100"
snmpset -c private -v2c 10.254.2.144 .1.3.6.1.2.1.17.7.1.4.3.1.1.100 s VLAN100 .1.3.6.1.2.1.17.7.1.4.3.1.5.100 i 4 It reports Error in packet. Reason: (genError) A general failure occured Failed object: iso.3.6.1.2.1.17.7.1.4.3.1.1.100
In same time changing the name of existing vlan snmpset -c private -v2c 10.254.2.144 .1.3.6.1.2.1.17.7.1.4.3.1.1.23 s VLAN23 and even deleting the existing vlan snmpset -c private -v2c 10.254.2.144 .1.3.6.1.2.1.17.7.1.4.3.1.1.510 i 6 are successful.
We are trying to config vlan 10 for data and vlan 20 for voice on the same port - port 1 of swtich SF300-24P to run both data and voice on different vlans.Do I have to add vlan 10 as an untagged vlan to port 1 and add vlan 20 as an tagged vlan to port 1?If I do not want to assign the native vlan 1 to port 1, how can I remove it ? The GUI page - assign VLAN to port does not allow to remove it.Aslo, what mode shall I set up on port 1? General, trunk or access ?
I have a Netgear GSM7248R switch with 5 different Vlans including th management Vlan. Each of the vlans are connected to my layer 3 switch for routing. I want to access the management vlan form any of my Vlans so my layer two switch can be detected by my snmp manager.
I have some problem in my small network.I have 2 SF-300 48 port switches and connected to 847 router for intervlan routing. I configure 7 vlan in SW1 and uplink to SW2 with trunkport.
The problem is that if i used default gateway for users ip address of interface (vlan interface) is ok. I bring two adsl modem and connected to vlan1 and vlan2 for internet access. When i connected this two modem vlan 1 and vlan 2 are not going to access other vlan 3,4,5,6,7 and wise versa.
vlan1 users getting default gateway from adsl modem ip, how i can permit this two vlan should to access other vlan 3,4,5,6,7 and 3,4,5,6,7 should access to internet also.
I have a number of class-'c's as a hand-off from my data center fiber to my 2960, which then sprawls the racks with about many 2950 switches, mostly 20 machines per switch. To allow machines on one 2950 to push data to another 2950 without routing back to my ISP's router(which costs money for bandwidth) isn't is possible to trunk one port on each 2950 to another 2950 and adding a addititional vlan8 to them. Then data jumps from 2950 to 2950 without going back to the 2960 or mainly not going back to my ISP's router. Is this the correct way to accoplish this with extra vlan and trunking the 2950's to each other or am I looking at this all wrong?
now we have 2 switches: SF300-24..on one SF300-24 we config it at layer 3 mode with VLAN configuration same as following [code] And we use port 26 on 2 switches SF300-24 is trunk mode then we connect both SF300-24 switches.But on SF300-24 layer 2 cann't inderstand VLAN from Sf300-24 layer 3..How to config VLAN on 2 switches SF300-24 Layer 3 and SF300-24 layer 2?
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.
