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.

After performing a firmware upgrade on an SG300-20 switch from ver 1.1.0.73 to 1.2.5.70 the switch now boots up with the following error and resets:
30-Aug-2011 10:47:33 %L1Mngr-F-PARAMTOOLONG: csco-sb parameter %s is too long.
The attached file contains a full output of the console boot process. I have tried loading different versions from the console, but all produce the same error.

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?

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.

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).

I have a problem. Yesterday I have upgraded both my SG300-20 switches to firmware v1.2.7.76. Now I cannot login on of my switches, unknown username and password. I am absolutly sure I have the password, because they are the same and I just upgraded it. I have re-booted the switch, but without any luck.

I have a question regarding SG300 series small business switches.If I switch between the two possible images, will the configuration get lost or is the configuration the same independent of which image I choose?

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.

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.

I have several SG300-10 and SF302-08P switches running with L2-mode, and after I upgraded their firmware to 1.1.2.0, they began to record the following logs every one hour.
- Severity: Warning
- Description: %COPY-W-TRAP: The mirror-config file is illegal due to failure of previous copy operation/s to mirror-config.Also I found that I didn't see the Mirror Configuration file on the Configuration File Table in the Configuration Files Properties page.

I have just attempted to load the latest firmware on an SLM2008, everything appeared to work as expected BUT, the switch is no longer pingable on its static IP doesn't appear to have attempted get an address via DHCP. I have attempted power cycling the switch but it has made no difference. The switch is still switching but I have no management any more. What to do next ?

Using the SGE 2010 for Microsoft NAP with 802.1x auth for switch access, which led to a few issues
What i have: An SGE 2010 48 port switch, firmware 3.0.0.17 Firmware upgrade: In order to ensure im not having problems due to old firmware, i tried to upgrade using ros_ls1_bp_ge_bx-3020.ros in order to move to 3.0.2, when uploading the file via TFTP, the upload completes and thats it, nothing happens.Restarting the device: As part of the upgrade process, i thought i might of had to reboot, so i rebooted, and found that all my settings were wiped clean, as if a factory reset had been performed.... and add further to pain, the backup of settings that i had taken do not seem to want to re-apply.NAP support: So i have tested my NPS (radius) server with NTRadping.exe and all is good, however i cannot get the SGE2010 to talk to it.... the authenticator state in the web interface is always listed as initialising.... im not sure if this is a simple incompatibility (hence the attempt at a firmware upgrade), a tag that needs to be set on the radius side or a switch misconfig.
1) how on earth do you upgrade the firmware?
2) why are none of my settings being saved when the device reboots ?

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 )
HW version V01

1) I have a Cisco SG300-28P. I plan to add a SG300-52. Would it be possible to manage the new switch through the SG300-28P web browser ?
2) There are 2 fans in the POE model SG300-28P. How many fans are they in the non POE switch SG300-52 ?

I recently upgraded the flash and the RAM on one of my ASA 5505 lab machines. The flash was upgraded from 128 to 512MB and the RAM was also upgraded from 256 to 512MB. I am using asa845-k8.bin. The firewall boots and runs file until you issue the reload command. The system shuts down but never reloads.

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?

Recently, we had a 3750X stack of 9 switches reload with no information as to why. Our syslog server received no spurious errors regarding the cause nor did the location lose power. The UPS to which it is attached logged no glitches relating to power. Other cisco devices (router, other switches not in the stack) did not reload. No one was in the MDF during this time. We self insure these line of switches so a TAC case is not an option at this time. Any forensic tools that I could try in an attempt to narrow down the cause.

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.

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?

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?

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?
