MGBLX1 & Cisco SG300-28
I am trying to connect the 2 Cisco SG300-28 switch using the MGBLX1 module with a single mode fiber cable. When I inserted & removed the module it detected (see attached screenshot) but when I see the optical module it is not detected (see attached screenshot), the shared port of mini-gbic is not blinking. Is there are any compatibility issues with switch, module or single mode fiber? What is the minimum distance of single mode fiber optic cable? Do I need to configure the switch to enable the mini-gbic?
I tried your suggestion but there is no light in the shared port. I will try a patch cable to test the module. How do I know if the module is defective?
Below are the logs.

Cisco SG300 - IGMP and multiple switches
Hi all,
I have read through various Cisco documents and tried various configurations and i have been unsuccessful
Here is the network layout
Cisco SG300-10 in Layer 3 mode, managing all VLANS created and inter-vlan traffic is working fine
Ports 1-4 are in LAG 1 with LACP enabled, Ports 5-8 are in LAG 2 again with LACP enabled, port 9 is connected to the ASA 5505 (Trunk port, all VLANS) and port 10, again a trunk port I use for management
LAG 1 and 2 are connected to Cisco SG300-52 switches
again traffic between the switches is working ok, what we would like to do is the following
on VLAN 7, we have multiple devices streaming using UDP multicast, what we would like to do is allow PC's on VLAN 5 to be able to pick up these streams as and when they need to, the devices broadcast on their own unique UDP ranges
Could someone please explain to me what I need to configure on the Layer 3 switch and the other two Layer 2 switches in order for this to work?
If i put a port into VLAN 7 and can view the stream without a problem, also if there is any fine tuning to be done once this is working
Thanks
AndyJason,
The only advantage you would get from using SFPs (fiber tranceivers) in the GBIC slots would be if you needed to make a run of over 100m between the switches. Unless you have a very large property with switches at either end you are just as well to use the copper ports in the setup you described. There is also nothing wrong with chaining the SG100s together if necessary to free up a port on the RV320. The only other thing to consider is if you are using VLANs. Each unmanaged SG100 will only pass a single VLAN so if you need segregated distribution coming from the RV320 you would need to put each SG100 on its own port. Or, you could run a trunk from a port on the RV320 to your SG200 and then split off your untagged VLANs from there. Hope this answers your question and have a nice day.

Cisco SG300 HOSTP_flash_operation: fatal error during read operation!
I have 2 Cisco SG300-52P switches. Earlier this week, one of them started dropping connections and POE was not working on a couple of devices... I came in this morning to restart them when no one else was around. After restarting them, the troublesome one was still not detecting POE devices.
I have been waiting for some down time to do a firmware update, so I thought this might straighten things out. I Downloaded the updated bootloader and firmware from Cisco's site. Updating the (non-problem) SG300 went exactly as it should. Upgrading the the bootloader on the problem SG300 went exactly as it should. Started the firmware update on the problem switch ....... and it didn't come back online. The power light was flashing, and occasionally the lights on ports would blink like they were trying to reset, but they never made it. There weren't really any special configurations on this switch so I had nothing to lose by trying a factory reset via the pinhole on the front ...... same result.
I connected to the serial port via a win7 PC with putty. .. All setting per Cisco. I got a message that the connection was detected, but it would not accept keyboard input. I power cycled the SG300 and watched the messages go by ... It looked like everything was working. I even got a message that the "Initialization task was completed"..
Then this message "HOSTP_flash_operation: fatal error during read operation!"
We have had a couple of internet and power outages recently, but I am trying to rule out other issues before blaming it on that.
any suggestions?
putty output file attachedI am not familiar with SG series products, but looking at the error message in the attached file, it appears there is an issue with reading from the flash. It could be that the flash file is corrupted and the flash needs to be formatted and then reload the software again.
If you have support contract on the product, I would suggest you open a TAC ticket with Cisco and have them help you.

Cisco SG300 and LLDP with Yealink Phones.
I am currently trying to setup a Cisco SG300 switch with a hosted VoIP solution using the SG300's at the customer's premise. The Yealink phones I am not able to get them to pull an IP address and believe the problem is related to LLDP. We also use Polycom phones and they work just fine. Here is the configuration that I am currently using ( I have tried several different configurations and none of them work with the Yealinks. Any help would be greatly appreciated.

Cisco SG300 Network Expansion (Configure 2 Switches)
I’m currently in the process of expanding my network having bought a second Cisco SG300-20 which is now sitting in my lab, my current setup is described below
Internet
^
|
Draytek Router 192.168.1.1
^
|
Cisco SG300-20 192.168.1.2
^
|
VLAN 12 Workstations interface 10.0.12.1
VLAN 13 Management interface 10.0.13.1
VLAN 14 Pubic interface 10.0.14.1
VLAN 15 Private interface 10.0.15.1
VLAN 20 Storage interface 10.0.20.1
I then have a number of servers with multiple nics that run on the various VLANS attached to certain ports in the Cisco Switch
VLAN 12 and 14 have been given access to the internet with routes added to Draytek to 10.0.12.1 / 10.0.14.1
Now what I want to do is to expand the network running a link from my first switch to the new switch. Ive read a number of notes on this forum but confused as to what I need to do.
I want the new switch to have access to all the VLANS configured on the first switch and will set the ports access to the various VLANs for each server that is being connected.
Have read that its best to have any additional switches on the network configured as Layer 2 and leave just one switch to do the routing (is that correct?). So have left the new switch as Layer 2 and given it an IP of 192.168.1.3
So the first question is how do I configure the uplink port from switch 1 (Port Gi2) to Switch 2 (Port Gi1).
Should I run multiple cables and create a LAG between the two switches? Allowing for additional bandwidth (I stream a lot of HD movies across the network to the workstations)
I have attached my running config from switch 1 below.
Any help would be appreciated, unfortunately networks are not my strong point.

prcswitch01#Hi Aleksandra,
Im still having issues with my setup. The servers I have connected have VLAN tagging enabled
Previously I had my esxi server connected via two nics with ports configured on my Layer 3 switch prcswitch01 as follows
Port 1 Trunk VLAN 13-15
Port 2 Trunk VLAN 13,20
My NAS was configured on a single port on VLAN20
The ESXI server can only have a single gateway which is used by both interfaces
~ # esxcli network ip route ipv4 list
Network Netmask Gateway Interface Source
default 0.0.0.0 10.0.13.1 vmk0 MANUAL
10.0.13.0 255.255.255.0 0.0.0.0 vmk0 MANUAL
10.0.20.0 255.255.255.0 0.0.0.0 vmk1 MANUAL
Traffic was being passed from VLAN13 to VLAN20 to allow connectivity to the NAS on the ESXi server
This no longer seems to be happening on my Layer 2 switch.
I have configured the ports the same as previously setup on the Layer 3 switch.
When I have the esxi server connected I can reach the server on 10.0.13.11 but the server cannot ping the NAS on 10.0.20.196
Hope that makes sense, I’m confused about setting this new switch up. Should I configure it as Layer 3 and setup interfaces for the various VLANS. I was under the impression this would be done by my first switch.
Thanks

GVRP not working on Cisco SG300-28
I have three Cisco SG300-28 switches. I setup a test lab environment with a core (server) switch in Layer 3 mode and the rest are (clients) in Layer 2 mode. As I understand, these switches doesn't support VTP, only GVRP. And GVRP works the same with VTP. Whenever you create VLANs on the core or main switch, other switches will learn from the core switch and no VLAN creation for the client switches will be made. (Hope I got it right. I guess GVRP is more complicated than VTP).
GOAL: Obviously, I want to use GVRP to create VLANs on the main switch so that I won't be doing it all over on the other switches.
The following is my (so far) configuration through CLI only:
I haven't use the web GUI. My SW version is 1.1.2.0.
1. I already enabled the GVRP globally.
2. I configured GE 12 & GE 24 as TRUNK ports for the core switch that connects both switches, I also configured GE 12 ports for both the client switches. All other ports are in ACCESS mode. (I am connected to GE 2 port)
3. I enabled GVRP on the TRUNK ports only for all switches.
4. I allowed all vlans on the TRUNK ports. (#switchport trunk allowed vlan add all)
5. All TRUNK ports registration mode is NORMAL and dynamic vlan creation is enabled on all trunk and access ports.
6. I created 3 VLANs without configuring its IP Addresses:
vlan 2 = MGT
vlan 3 = IT
vlan 4 = MKTG
I don't know if I missed something on the configuration or the connection. I was expecting the vlans I created will be learned from other switches. Hope somebody can help me out. Thanks a lot.
QUESTIONS:
1. Is it necessary to enable all switches to layer 3 mode? Or depends on the network setup? Does this affect the GVRP?
2. Does switching ports to TRUNK mode means they are already 802.1q ports by default? Because I can't configure TRUNK ports to 802.1q (#switchport encapsulation dot1q) config like other switches.

Cisco SG300-28 / SGE2000 / Catalyst 2960
Hello everyone,
I'm looking for switch to accompany Cisco ASA 5520 in data center, with 20+ GE ports and no need for PoE.
I would like to understand the difference between Cisco SG300-28, Cisco SGE2000 and Cisco Catalyst 2960, 2960-C and 2960-S Series (except specific number of ports). As far as I can see the Cisco SGE2000 has 4x SFP and is stackable unlike the SG300 with 2x miniGBIC/SFP, but not much else. Cisco Catalyst 2960 series offers some additional features like USB storage, but I can't imagine I will need that.
Any suggestions?
Thank you
DanHello everyone,
I'm looking for switch to accompany Cisco ASA 5520 in data center, with 20+ GE ports and no need for PoE.
I would like to understand the difference between Cisco SG300-28, Cisco SGE2000 and Cisco Catalyst 2960, 2960-C and 2960-S Series (except specific number of ports). As far as I can see the Cisco SGE2000 has 4x SFP and is stackable unlike the SG300 with 2x miniGBIC/SFP, but not much else. Cisco Catalyst 2960 series offers some additional features like USB storage, but I can't imagine I will need that.
Any suggestions?
Thank you

I have a Cisco SG300 small business switch and 541 APs. There are 2 VLANs in our network. One must be limited by bandwidth. Does anyone have an idea for configure vlan rate-limiting on SG300? And please describe CIR & CBS for me. Thanks.
http://www.cisco.com/en/US/partner/products/ps10898/prod_command_reference_list.html
Cisco Small Business 300 Series Managed Switches Command Line Interface Guide Release 1.3
Select CIR and CBS according to your design. You can use a larger CBS when performance is not ideal.
49.23 rate-limit (VLAN)
Use the Layer 2 rate-limit (VLAN) Global Configuration mode command to limit the
incoming traffic rate for a VLAN. Use the no form of this command to disable the
rate limit.
Syntax
rate-limit vlan-id committed-rate committed-burst
no rate-limit vlan
Parameters
• vlan-id—Specifies the VLAN ID.
• committed-rate—Specifies the average traffic rate (CIR) in kbits per second
(kbps). (Range: 3-57982058)
• committed-burst—Specifies the maximum burst size (CBS) in bytes.
(Range: 3000-19173960)
Default Configuration
Rate limiting is disabled.
Committed-burst-bytes is 128K.
Command Mode
Global Configuration mode
User Guidelines
Traffic policing in a policy map takes precedence over VLAN rate limiting. If a
packet is subject to traffic policing in a policy map and is associated with a VLAN
that is rate limited, the packet is counted only in the traffic policing of the policy
map.
This command does not work in Layer 3 mode. It does not work in conjunction with
IP Source Guard.
Example
The following example limits the rate on VLAN 11 to 150000 kbps or the normal
burst size to 9600 bytes.
switchxxxxxx(config)# rate-limit 11 150000 9600 -
Hi,
We have Cisco SG300-28 in our server room which is connected with Cisco 3750 from where it get the uplink. There are 10 ESXi servers connected on SG300. Switch gets more the 100 VLAN via trunk. My issue is, while pinging any of the ESXi VMs which are in different vlan from laptop connected to 3750, a lot of packet drop is observered. Issue is only seen on SG300. We have other switch connect to 3750 on which other ESXi servers are connected but dont see a single packet drop on that. Amount of traiffic flow is not much high. Is SG300 capable enough to take such traffic??
I see lot of Tail drop packet on QoS menu of switch's UI.trust me i am also heaving the same issue with my 3 Cisco SF300-24 ports ad i need the same what you was looking forward for...
can you please check my question and comment what i am missing :(
Aside to this i will try creating Vlans on my client switch without assigning the ip address as it's already assign and created on core switch.
Thanks,

LAG configuration issue on Cisco SG300 52 Switch
Hi everybody,
I am having an issue with LAG configuration on a Cisco SG300 52 switch. I have connected four Ge ports on the switch to the four NICs of a Dell R710 Server on which I installed Windows Server 2008 R2. Without LAG configured, these ports would forward traffic to and from the Dell server fine. However, if I configure LAG on the ports with LACP enabled, then they would not forward any network traffic. Debugging shows that the ports are up but their forwarding status show N/A. Am I missing any configuration? Can I configure LAG on edgeports? Or is there any compatibility issue?
Any help from you guys will be greatly appreciated.
Thank you.
VishalHi Dave,
Thank you for your quick response and sorry to have looked at it late. Well, I already resolved the issue and like you pointed out, it was the configuration of the Dell NICs. I had to configure NIC teaming and there was a bug with the Broadcom NIC management software. I had to download this piece of software again and I was then able to configure NIC teaming on it. I initially thought that it was already configured because we got the Dell server "pre-installed with pretty much everything".
Anyway thank you for your assistance. Oh I have a question though if you don't mind clearing my doubt. We have bought 7 of these SG300 Switches and I would like to use all of them
in a hierarchical design as core, distribution and access layer switches because I believe this switch has got all the qualities to be used at all the three layers. We have about 100 users in our company at the moment but expecting growth of about 10-20 employees per year. Would you think a hierarchical network design for a 100 users is a bit of an overkill? Would you think these SG300 switches can handle network traffic at the distribution and core layers? I worked out the average daily traffic is only about 4 Mbps.
Thank you for your valuable guidance.
Kind regards,
Vishal

Hi Chundunsing,
Thank you for the purchase of my switch.
Chundunsing, I love the way you worded your question ; "I am having an issue with LAG configuration on a Cisco SG300 52 switch." ,but seriously you are having a problem with interfacing the dell with my switch.
You have LAG working to the Dell R710 teamed NICs and god knows what NICs or drivers you are using to acheive this.
Now LAG is providing , load balancing between the LAG ports.
Now LAG is providing , link redundancy for connectibity to the Dell R710.
If there is a configuration issue , it sure seems the way you have it configured without LACP is still working. But you have the option when you create a LAP group to enable LACP. You can see this as a tick box in the LAG group.
But might i also install, recently firmware version 1.1.1.8, just came out.
Please be sure to;
Step 1. update the firmware on the switch and
Step 2. select it as the 'active image.'
Step 3 rebbot the switch to utilize this active image.
If you are having any trouble doing this the admin guide references how to achieve this. for your concenience I have atteched the guide to this posting.
regards Dave
