Cisco Switches :: SGE2010 - Firmware Upgrade And Configuration Not Saving?
Oct 7, 2012
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 ?

what is the process of updating firmware on a SGE2010.
I would usually use TFTP - but, I can't see the TFTP command on these SGE2010's

I have a couple of SF300-24 switches. When I made needed configurations using CLI or GUI and then saved all configurations. The problem is that switches do not save configurations after reboot.

I have a number of SFE2000 10/100 24 port POE switches. They are configured and running OK. I want to be able to save the configuration and be able to load that saved configuration into another new swich in the case of a failure.
I have logged in and gone to Admin-File Management-Save Configuration. I then select the 'Backup' radio button and TFTP the configuration to my TFTP server. All works OK and I have a readable text file with the switch configuration on my TFTP server.
I want to be able to restore that saved configuration on to a new switch. I have set the new switch back to factory defaults. I go to Admin-File Management-Save Configuration. I then select the 'Upgrade' radio button and try and uploade the file into the switch. If load to 'Running Configuration' the switch shows a status of 'Copy Finished' but says 'Copy completed with errors' If load to 'Startup Configuration' the switch shows a status of 'Copy Failed' and says 'Copy completed with errors'
I am guessing I should be able to load my saved Configuration back into a switch, shouldn't I??
And yes the switches are running the same firmware 3.0.0.17

Id like to set up our AP to push our different vlans depending on which ESSID you connect to.
A few things I am unclear on. The switch port on the SGE needs to be in trunk mode I assume.
Do I marry the Management Vlan ID on the AP to the PVID on the SGE port ? Or is the PVID the untagged vlan ID ?
I set the switches port to trunk mode, it's PVID to 10 and set the management vlan ID on the AP to 10 and I get TTL Exceeded in Route when I try to ping.

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 ?

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.

Simple, here the result when I try to install the firmware "ls_106-12216.ros" or "SRW224G4P_SRW248G4P_image_v1020.bix" that came from your web site!
Here the result for "ls_106-12216.ros"

After setting up the newly arrived router, renaming the SSID and changing password for 2.4 GHZ AND 5 GHZ and also renaming the default router username and password, I decided to update the firmware.The procedure wiped all configuration I've made forcing me to do all over again.

I have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.

I currently have two SGE2010's with a 4-port LAG configured between them. I'm looking to add another two SGE2010's and I want to add redundancy at the same time. The switches are currently in standalone mode. I don't have fiber connectors and was planning on just using copper for the uplinks.
My questions are:
- Is it possible to use stack mode in conjunction with 4-port LAG groups to create redundant 4-port links between all of the switches? The documentation says that ports 24&48 are reserved for stacking - does that mean I can't specify a LAG instead?
- If 4-port LAGs aren't possible, does that mean that these switches max out at 1Gpbs uplinks if you use stack mode?

I'm having 1841 Router, its configuration is not getting safed. If I reboot the router all my running-config is like default. But when I check my sh startup all the configuration which I did is displayed. Checked the config-registery too and its 0x2142 changed too 0x2102 still the same problem, when reloading the router all the running config is disappeared.

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 a Cisco 850 router that whas having problems getting an ip address via DHCP. I did some stuff on it but that didn't work, so I rebooted the router to go back to my last saved startup config. When I turned it back on and connected t othe CLI console I got the "Would you like to enter the initial configuration dialogue?" message. Thinikng I just forgot to save anything to the startup config I went through the initial set up again and made sure to save everything to the startup config. After going through the intial config and setting up a vlan to assign DHCP to clients I saved the config and rebooted, upon reboot and connecting to the CLI console I got the same "Would you like to enter the initial configuration dialogue?" message. Tryign the setup once more and making sure everything was saved to startup config I rebooted again just to make sure the changes would stick, and sure enough they didn't. Whay is the config not saving to the startup config?

I'm running LMS3.2 and RME 4.3.1. I deployed a netconfig job to our network which consisted of approximately 800 devices.The report said that the job completed successfully however some of the devices didn't save thier running config to startup.
Is it possible to add a command or issue another netconfig job just to save the running config, so I can identify if the job fails on some devices? Using the tick box in the netconfig job doesn't seem to alert you if its not successful.

I have a 1711 Catalyst router hooked up behind a cable modem. I configured the router, copied running-config to start up-config then wrote it to memory with "write mem". I unplugged router to move it and when I plugged it back in, I had to start from scratch.
Is this normal, or should router be able to save configuration if powered down?
BTW, I'm using Putty to access router console. Is that the hot setup for Windows 7 or is there something better?

I currently am trying to program the config for a 1720 router however i cannot get the config to stick. I boot up to the command prompt put in all the configurations use the "write mem" command and then hard reset the router but when it boots back up I get the initial system configuation dialog.
I have tried booting to the rommon prompt and typing "confreg" and following the prompts keeping all options set to no except for this setting
"enable "ignore system config info"? y/n [n]: Y"
Is set to yes. but when i get to the end of the config it just loops and starts over with
"you wish to change the configuration? y/n [n]: Y"
If i choose yes it loops if I choose no it goes back to the rommon prompt.

I have a hybrid kind of network. I want to create create two VLANs on Cisco SGE2010 so that these two VLANs should not talk each other but at the same time they are able to talk Domain controllers, DHCP and other servers which are on other switches.I am able to create two separate VLANs but they stop talking with other servers(DC, DHCP, etc) which are on another switch.

I am working on two SGE 2010 stacked and in routing mode. Everything work fine but before finishing the job, I wanted to lockdown all the network device so they would not be accessible from some subnets. Problem is, I cannot bind my ACLs to any interface. I get "Cannot apply because lack of HW resources." I am running firmware 3.0.0.18, and 3.0.1 release notes don't address that issue. TCAM utilization is at 3% Routing resources shows host: 200, routes:60, ip interfaces: 50 I have tried from the cli and get the same message.

Is there any issues with accessing the browser based GUI using Windows 7 64bit on a SGE2010 switch? I took the switch home and tried on my XP 32bit machine and works fine, but no luck on any windows 7 64bit pc's. I have tried 3 different new pc's on this new switch and no luck at all.

We have a single SGE2010 in layer 3 mode switch with a Server 2008 DHCP server.
We will be implimenting a Voip netowork where the PC's connect to the voip phone. I would like to create another vlan - 10. I have created the vlan and assigned the IP on the swtich.
Routing seems to be working. I can ping both IP addresses of the switch on either vlan.
I cannot get DHCP working. In the SGE switch I have enabled DHCP Relay, enabled option 82, set my DHCP Interface as VLan1, and specified the DHCP servers IP address. On the ports I have set the port where the DHCP server connects to as a trunk port with Vlan 1 untagged and vlan 10 tagged. I have set the ports where the phones connect as a trunk port with vlan1 untagged and vlan 10 tagged.
