Cisco Switches :: SG300-28Ps - 1.3.0.59 Firmware / PoE Indicators No Longer Lit?

Mar 28, 2013

I installed the 1.3.0.59 on a couple of SG300-28Ps.  On the Status and Statistics page, the PoE indicators no longer lit. Physically, on the front of the switch, they did still light.  I didn't yet reboot to factory defaults to see if that clears it, because I don't feel like entering the config again this early in the morning. But I am willing to test that, if needbe.
 
When reverting the image back to 1.2.9.44 (tested) or possibly earlier, the ip default gateway must be re-entered (if it was configured). Even if ip-default gateway x.x.x.x shows up correctly on a 'show run', the switch will not obey it, and on the IPv4 settings page it will report the operational default gateway as blank. This came as a surprise becauset he switch suddenly wouldn't talk to the VPN anymore.

Logging onto the switch locally, going to the IPv4 settings, ticking the radio button back on User Defined and typing it back in cleared that up. It appears this cropped up because the syntax for specifying the default gateway changed in 1.3.x but it's still odd that the config shows correctly in console but not in the gui.

Cisco Switches :: SG300 On 1.1 Firmware Has Double-Login On SSH

Jan 4, 2012

We just upgraded our Sg300 series switches to the new IOS so we can get CLI access. The upgrade went fine but it seems we have two login prompts, the first being completely unnecessary as you can just hit return to get by it. IE here is the progression: 
 
1. Connect SSH

2. Receive a "login:" prompt. Anything can be entered here, including just return

3. Login banner is displayed

4. Username Prompt is then displayed. Valid username required

5. Password Prompt displayed - Valid password required

6. Now at CLI 1. Connect SSH

I am trying to get rid of that first login prompt (IE Step 2) as it is causing issues with our configuration software. I have tried every line and authentication command I can think of, the only thing that gets rid of it is using none authentication which obviously we can't stay with. how did you get around it?

Cisco Switches :: SG300-28P DHCP Server With New Firmware?

Jun 15, 2012

we are looking to use the new firmware's DHCP server feature to setup different DHCP scopes for 5 different VLANs configured on the switch. I see where to turn this on and setup the scope however I can't clearly see where I can assign the specified scope to each VLAN on the switch.

Cisco Switches :: SG300-28 RADIUS Accounting Firmware 1.0.0.27 And 1.1.2.0

Jan 27, 2012

I am using the CISCO SG300-28 with firmware version 1.0.0.27. I enabled RADIUS authentication and accounting. Authentication is working but there are no accounting requests/replys (Accounting on, accounting off, accoun ting start, accounting stop) when running RADIUS in debug mode. I also did a packetcapture and there are no accounting packets.
 
So i updated the firmware image up to version 1.1.2.0. When I now want to configure accounting in RADIUS settings then there isn't any option to set an accounting port.
 
Ich checked the data sheet of the switch and it says that accounting is supported:
 
===============================================
802.1X: RADIUS authentication and accounting, MD5  hash; guest VLAN; unauthenticated VLAN, single/multiple host mode and  single/multiple sessions [URL]
===============================================
 
I did a second packet capture with the new firmware image and there are still no accounting packets.
 
The RADIUS server is configured correct for accounting because when using another NAS like a WLAN-AP with DD-WRT accounting is workings. It is working with pfsense Captive Portal (an open source firewall and routing solution with a hotspot portal).

Cisco Switches :: SG300 Firmware Upgrade - How To Reload 1.0.0.27 Using CLI

Jul 27, 2011

I've been having a problem with a brand new SG300-10 switch that I posted about yesterday. I checked the firmware and it was at 1.0.0.27 and the lastest is 1.1.0.73. So I backed up the current firmware and loaded the 1.1.0.73 version and it seem to be CLI based only, with no web GUI.
 
If so is there an easy way to reload the 1.0.0.27 using the CLI? There is nothing in the CLI docs that I can see unless it's buried.
 
The release notes for 1.1.0.73 don't say it's CLI only either, maybe something just went wrong but the CLI seems to be functional.

Cisco Switches :: Convert SRW2048 Software To SG300 Firmware?

Aug 14, 2011

I believe the SRW series is the same basic hardware as the SG300 series.Is there a way to upgrade the firmware on the SRW series using the SG300 firmware?
 
The SG300 firmware is much more usable. Also I'd rather have consistency as we have the older SRW2024/48 and the newer SG300 switches.

Cisco Switches :: SG300-28 GUI Different Than Online SG300-48 Simulator

Aug 29, 2011

These are our first switches and seems like GUI is lot different than the online. Out intervlan routing is o not working. I am absolutely sure that I setup the switch in L3 mode since it allows me to create mutiple interfaces. I am hoping that this GUI issue is related to interVLAN routing.
 
Below is the blog I started for InterVlan issue [URL]
 
This is the link for online simulator and what I see in its IP tab. I know this switch is not SG300. [URL]
 
This is what I see on our switch.
 
Our switch version
switchd64684#show version                                                                                                                                              
SW version    1.1.0.73 ( date  19-Jun-2011 time  18:10:49 )
Boot version    1.0.0.4 ( date  08-Apr-2010 time  16:37:57 )

Cisco Switches :: Difference Between SG300-28P And SG300-52

Jul 25, 2012

I have SG300-28P that I am using as layer-3 switch. Recently I ran in to SG300-52 switch and even though loading same firmware doesn't give me option to do layer-3 switching. For SG-300 I see options in GUI to create vlan interfaces under IP information section, while SG300-52 has IP information option only under the management section.let me know if these are 2 different hardware types and L3 is not possible on SG300-52. If its possible to enable L3 switching on SG300-52?

Cisco Switches :: SG300 Switches Have Poor Performance In Layer 3?

Jan 1, 2013

We have several of the SG300 Serices switches. We use them to route VLAN traffic to Remote Offices, Internet Connections, and WiFi Access Points.In one remote office we have a SG300-10 setup to route the HQ Network and the remote Office Subnet. The SG300 is Connected to HQ via Fiber and has multiple Tagged VLANs on it. If I do speed tests over the Fiber Link on the Incoming Tagged Netwotk I get Decent performance, 80Mbs. If I switch to a networtk that is not priginating from HQ, and have the SG300-10 route packet, I get dismal performance. 15-20Mbs.
 
I Fireded up a New SG300-28P FW v1.2.7.76. Added a the HQ VLAN 101 and new VLAN 1025 . Mapped some Tagged and untagged ports for each.  Switch was connected to HQ Network as untagged VLAN 101.  I put a laptop on an Untagged VLAN 101 port. Ran some tests, cam back with 750-850Mbs. Great.  Put the same laptop on a Tagged 101 Port, Configured the NIC for Tagged VLAN 101, Same test, same Speeds, 750-850Mbs.I then  Configured laptop for Tagged VLAN 1025. Connected to tagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!
 
I then  Configured laptop for Untagged VLAN 1025. Connected to unagged VLAN 1025 port. Ran speed tests, resuts were 15-20Mbs!It was only the Laptop and the Connection to the HQ net on the SG300-28P. Why is the performance of this unit soooooo poor when it needs to route?Other Switches have FW v1.0.0.27 or FW v1.1.2.0. They have Similar speed issues. All Configured for Layer 3.

Cisco Switches :: SG300 Switches Can Be Used With Microsoft NLB In Multicast Mode

does the SG300 switches can be used with Microsoft NLB in Multicast mode?I know on traditional Catalyst switches you can statically "map" IP's to mac's and then to multiple ports but this doesn't seem to work correctly on the SG switches - it gives an error about the mac not being not Unicast?

Cisco Switches :: Multiple VLANS And SG300-28P Switches Setup?

Aug 20, 2012

I'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?

Cisco Switches :: SG300-52 Multiple Lags Between Switches?

Jan 19, 2012

I'm having alot of trouble trying to connect more that one LAG between two SG300-52 switches.Basically i have configured both switches with the same vlans. For 2 of the vlans i would like to connect them together between the two switches using LAG. Switch1 has Vlan 5 (ports 1-12) & Vlan 10 (Ports 25-36) with LAG configured on ports 1-2 and ports 25-26. I have setup the second switch identical to the first. But when i connect the LAG's there is no connectivty. If i disconnect one LAG the other starts working.Can you only have i interconnect LAG between switches?

Jan 20, 2011

I have a laptop with an Intel Centrino 6300 Ultimate-N wireless card. With the previous firmware I was able to reach 300mbps while on the 5GHz band. Since I updated my E3000 to the latest firmware (1.0.04) I can only reach speeds of 144mbps. I have done a factory reset on the router and stll get the same result. Is there any way I can get it to reach 300mbps again with the current firmware?
 
Also, yes I have uninstalled / updated the driver software for my wireless card. I have also changed the appropriate settings for the 5GHz band. (40MHz channel width, using WPA2 encryption)

Cisco Switches :: SG300-10MP Keeps Going Down?

Jan 27, 2013

We purchased a SG300-52 last week to replace a 5yr old Dlink which has worked perfectly. 1 day after the SG300 went it it started crashing with this fatal error problem so I reverted the firmware back from 1.2.7.76 (latest) to 1.1.2.0 but I still get the problems.  It crashes when I have it on my lan with users connected or if I just have the switch on my desk with just my laptop connected, so it cant be a load issue or a network topology issue.  I already have a Cisco SGE2010 on my network without problems.

Cisco Switches :: ACL Binding On SG300 28P

The cisco SG300 28P  is running in layer3 mode and i have created a couple of vlans and one of them is a guest vlan. Now to my question, i create an ACL and an ACE that vill funktion so that guest vlan only can connect to the internet and not the rest of the internal network. And then i must bound the ACL to an interface port or lag, what i can see it is not possible to bind it to an vlan? so if i have a port on some of the other switches that is member of the guest vlan, vill the ACL on the SG 300 stop guest vlan trafic to the internal network that is comming from some of the other switches?
