Any snmpset commands to modify port vlan membership on SG300-28 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 have two Cisco SG300-20 switches. Both of them are configured in L3 mode. They have several VLAN's configured.
When I reboot my switches some VLAN membership settings are lost! I have already saved the settings over and over before rebooting, and even tried to save it to the backup memory and so on. Say for example I have changed port 9 to 14 from VLAN 101 to VLAN 105. I save the configuration, reboot the switch. And then the changes are lost. This is a big problem, because servers and my iSCSI network loose connectivity. They already have the latest firmware. This issue was there three firmwares before.
This issue pop-ups when I have a power loss, or I need to reboot/shutdown them manually. It may be off-topic but I also have the feeling that the performance of the switches goes down during uptime. A reboot solves the performance issue. I don't have a performance benchmark, but I can notice it on the performance transfer rate between clients and servers.
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.
View 8 Replies View RelatedI've got an SG300-10 connected back to back (trunked) with a Cisco 3560X switch, across a fibre link and am seeing some big inconsistencies in terms of unicast data transferred across the ports between them.
During a night time window of 4am - 6am I run backups which involves a large copy of files, that almost saturates a GigE link - we can see from the 3560X end that the link is running at a bit over 800MBit/sec of throughput, sustained. The duration of this transfer is consistent with the size of the files being transferred (ie just over an hour, and is what I'd expect for a data transfer of about that amount). Back-of-the-envelope calculations indicate that the 3560X is measuring this data throughput correctly.
However on the SG300 end of the link, which is also being polled by the same application (Cacti), I'm observing spikey counts of only around 20MBit/sec during that window. These counters are very obviously incorrect - there's a huge amount more data moving across the port than that. The incorrect calculations are showing on both the trunk port out of the SG300 (uplink) as well as the interface where the NAS is connected in (which is an access port).
Cacti is polling the OID: .1.3.6.1.2.1.2.2.1.16.57 which translates to IF-MIB::ifOutOctets.57 = Counter32.I'm running version 1.3.0.62 but this problem is not new to this release - previous releases and 1.2 based releases also had this problem.
It looks like multicast traffic may be being counted correctly (that's only a suspicion though), however what I am certain of is that there is a very large discrepancy with the unicast traffic counts.Is this OID the correct one to be using for this switch?
how to configure SNMP on the Cisco SG300 switches? I have the SG300-10P. I am not fully familiar with the new command line interface on this device, it was easy on the IOS but finding it a nightmare on this one.
I put the following command in but it didnt work.
snmp-server view Interfaces interfaces included
snmp-server community ACB123 ro 10.x.x.x view default
I tried to follow the guidelines on the cisco website but thats all Web interface based, i can only access the switch remotely via CLI.
I was positively surprised to find the optical transmit/receive values using the show fiber-ports optical-transceiver detailed command on a SG300-10.
Now I'm wondering if there is also a SNMP-MIB to query these values? I've already tried the CISCO-ENTITY-SENSOR-MIB used by the larger devices running Cisco IOS, but this didn't work.
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?
View 9 Replies View RelatedI 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. .
View 0 Replies View RelatedBefore 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.
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]

It's working fine, but the problem is that it isn't possible to add all the Multicast Groups to the Multicast VLAN because each TV channel use other groups. For me it's only to handle if I can use wildcards to add a specific range of multicast traffic to the Multicast TV VLAN. Is that possible with that Switch?

View 1 Replies View RelatedUsing a sg300-52 switch I created two VLANs that share a port for access to the internet. All original devices added to the VLANs are functioning correctly so I have to beleive the VLANs are set up correctly. I added a new desktop and an old laptop to the VLAN and neither worked. I was able to get the desktop to work by enabling VLAN tagging in the network adapter. The laptop is 5 years old and it does not have any such setting in network adapter. There are 2 other devices that share the same port with the laptop and they both function properly. My conclusion is that the laptop does not support VLAN tagging. Is there someway to configure the switch to account for this?

View 8 Replies View Related 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

View 1 Replies View Relatedwe have an SG300 latest 1.3 firmware, we have it acting as our DHCP server, we have a 10.10.1.x range, 10.10.3.x range, and 192.168.24.x range, they are all on seperate VLANs and all can talk to each other which is what we want. However we have someone who wants to use the 192.168.1.x range to add IP cameras to our network using there own switch. I figured I'd just setup our server to do DHCP etc and it would communicate with the 10.10.1.x range of IP addresses no problem. It turns out the SG300s can't do DHCP for that range, so if he has all static address on the 192.168.1.x range how can i setup inter VLAN communication so we can talk to that range?

I am using several SG300-28 Switches with firmware version 1.1.2.0.I have dynamic VLAN enabled. As RADIUS server I am using free radius 2.1.12.Authentication is only based on the MAC address. (I configured that on the switches)On the switches I created three VLANs. VLAN100 for the authenticated clients, VLAN200 for Management interface and VLAN300 as Guest VLAN. After a wrong authentication the clients should be put into this Guest VLAN immediately (I configured this on the switches). I am using Windows XP and Windows 7 clients in my network. I did not configure any EAP settings because I just wnat to use the MAC address.
In most cases the dynamic VLAN assignment and authentication is working fine. The switch log says that the client is authenticated and the same I can see on free radius log. But in some (rare) cases the client is rejected. The CISCO log says "MAC aa:bb:cc:dd:ee:ff was rejected on port ge17" but when I look at the free radius log then this MAC address was successfully authorized.
The problem is that the client gets an IP address based on the Guest VLAN300 but after that the switch seems to "switch" the VLAN on the port and then the client is authenticated correctly on the right VLAN but the client does not request a new IP on the new VLAN. If I unplug and re-plug the LAN cable in most cases the client get the correct VLAN and the correct IP. This is happening randomly on nearly all my PCs.
Do I have to set some timers higher ? I don't think it is a problem between switch and RADIUS but a problem between communication of the host and the switch.

I have 2 SG300 switches and all I want is to propagate VLAN info from one to other. I do not have computers with GVRP compliant NICs, so I dont want that auto registeration functionality on access ports. I want VLAN prop via trunks and switchport mode access on access ports just like VTP. I have read on cisco docs that this functionality is provided with GVRP Mode fixed, but there are only 2 modes that I can see on SG300 are Normal and Forbidden. Trunk configured correctly, gvrp is enabled globally and on port, ports are up and functional, tried different combinations of checking and unchecking boxes of dynmic vlan creation and enable registeration on both ends but no joy. When I create a vlan from one, it doesnt propogate to other.

View 3 Replies View RelatedMy organization wishes to host a LAN gaming event. The setup I have in mind involves a 24-port switch for connecting all the player computers and having that switch connected to a smaller "core" switch which has the the game server and router connected to it. I'd like to know if I can set things up as follows...
SG200-26 with ports 1-24 on seperate VLANs so they cannot talk to eachother. I'd then like ports 25 and 26 to be an aggregated (for bandwidth and redundancy) trunk port to carry all 24 VLANs plus an additional management VLAN (ex. VLAN 100) that will be used for accessing the switch. I'd like those aggregated trunk ports to connect to an SG300-10 "core" switch which will be connected to the game server and to a router for internet access.
I'd like the ability to have two network connections from the game server to the switch, one on the management VLAN and one on a different VLAN (ex. VLAN 50) that will be accessed by the players (ports 1-24 on the SG200-26). The core switch needs the ability to perform restricted inter-VLAN routing, in that it doesn't allow VLANs 1-24 to talk to eachother but they can talk to the server's VLAN but only through specific service ports (ex. port 12345, 12346). Is this possible?
Furthermore how would I configure the SG300-10 to allow VLANs 1-24 to talk to VLAN 50, but not themselves or VLAN 100. As well, I'll probably have the router on it's own VLAN (ex. VLAN 60) and allow VLANs 1-24 to access it but only through HTTP port 80 for web access.
