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.
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
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).
we are looking to use the new firmware's DHCP server feature to setup different DHCP scopes for 5 different VLANs configued 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'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.
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 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.
It baffles me because the admin console doesn't look like it will browse your computer for a firmware update. Rather, it prefers you to specify a tftp or http server. I don't know how I'd set up my computer to be the http or tftp server and it doesn't really go into detail on what configurations or commands that would need to be used. I've used a tftp client in the past to send a firmware to routers and whatnot but not serve one.
How can I access the we interface of this switch if it is configured to get its IP address from the DHCP server? Since it is DHCP I do not know what IP address has been assigned to it therefore I do not know what ip address to enter in the browser.
I can't access the WEBGUI on any of them. they are very busy, the network is working fine, but I can't connect to the webgui on them. I've even had problems with a few connecting to them via HyprTerm. I bought 7 of the 12 just last May. If I'd known they were end of life I wouldnt have purchased these, although they are an awesome 48 gig switch for the price.
I need to be able to VLAN these. How can I get back in? Power cycle?
Trying to replace 3Com Superstack II Switches (3C16980) with 100Base-FX Modules (3C16970) with a Cisco solution. Existing Fiber connector in Network closet on both ends is an SC connector (picture attached). What Modules, adapter cables do I need to connect to an SRW2048 switch at one end an SRW2024 switch at the other? Will this solution provide a Gigabit connection over the Fiber ?
I am looking at using SRW2048-K9-NA with MGBSX1 module at one closet and SRW2024-K9-NA with MGBSX1 module in the other closet at the other end of the Fiber cable.
I found an adapter cable that will convert an SC male to an LC Male and it looks like it will work but I have no experience with fiber. I attached a picture of this adapter as well. It is listed on line as - 1ft Fiber Optic Adapter Cable LC (Male) to SC (Female) Multimode 62.5/125 Duplex
I am trying to track down the SNMP MIBs for the Linksys by Cisco SRW2048. Please note that this is the model before the complete CISCO rebrand of the product. I have SNMP walked, browsed etc etc and I just can't pull CPU and RAM usage. Any working view of those two stats? I'm using OpManager by ManageEngine as my NPM platform.
I have lost the original console cable to the Cisco Linksys SRW2048 and was wondering if I can use the Cisco console cable or can a regular serial cable with female ends will work?
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
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?
I'm replacing 2 3COM 4500 Swithes with the SG300-52 Cisco switch. We have 3 VLANs, 10, 20, 100. The switch is set for Layer 3 and I have setup DHCP relay. what settings i should set on the Cisco for the following setups:
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?
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.
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:
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?
I have two SG300 serie switches and two Gigabit connection between them. How do I configured these two links to work toghether like a one 2 Gigabit channel?
I'm trying to upgrade my existing Netgear wired router to a Netgear N600 wireless router. I was really hoping just to replug in everything and go. But because the wired router is setup for 192.168.1.1 when I plug in the wireless router it thinks nothing is plugged in because it too wants to use that IP address. How do I disable the wired settings
My super awesome desktop with the regular gigabit, on board lan card (on Win7).A laptop, with wireless connectivity (again on Win7).A modem, UTStarcom WA3002G4 with an internet connection from BSNL.The modem is a wireless modem.Now for my question.I want to be able to connect the laptop and the desktop in a single LAN connection, so that i)I may play NFS Most Wanted on both the laptop and desktop through the LAN play.ii) I may share files and folders, fast and without any hassles.*though mostly only the firstSo, this being my completely descriptive question.
I just switched over from AT&T Uverse to time Warner cable for Internet. I bought a Motorola Surfboard sbg6580. I have the surfboard hooked up and all is well. Now I would like to do in put the old 2wire from AT&T in a room upstairs and use it as place I can plug in the Ethernet cords and also transmit another signal. I have what's a called plug link that is plugged in down stairs and then another upstairs and it allows the Internet signal to run through the power lines. So it just about the equivalent of running a cord for down stairs to upstairs. So basically I just need to plug more then 1 thing upstairs that isn't wireless and I would also like to transmit a 2.4ghz signal upstairs and use my Motorola to transmit a 5ghz.How would I set up the 2wire to do this.
