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 :: SG300-52 - Device Will Not Work On VLAN

Jul 13, 2011

Using a sg300-52 switch I created two VLANs that share a port for access to the internet. All original devices added to the VLANs are functioning correctly so I have to beleive the VLANs are set up correctly. I added a new desktop and an old laptop to the VLAN and neither worked. I was able to get the desktop to work by enabling VLAN tagging in the network adapter. The laptop is 5 years old and it does not have any such setting in network adapter. There are 2 other devices that share the same port with the laptop and they both function properly. My conclusion is that the laptop does not support VLAN tagging. Is there someway to configure the switch to account for this?

Cisco Switches :: SG300 Switch - Device Swamped

Oct 10, 2011

I have a recently purchased 28 port SG300 switch. Everything is working well. Unfortunately there is so much traffic flying around that a 10MB half duplex device is struggling to function as it is overloaded. Removing some of the sources of traffic fixes it.

Fortunately I only need to access that device from one PC on the network. That PC however needs to access everything else on the network.

Is there a simple way to shield the slow device from everything except traffic from the PC ?

The switch is in Level2 mode at the moment. Everything is on a single sub net.

Cisco Switches :: Disable Password Expiration Requirement On SG300?

May 13, 2012

I have a dozen or so SG300 switches and a few months after configuring and deploying them, I have noticed that as I'm logging back into them, I'm being told that I'm required to change my password as it has expired.  The problem I have with this is that we pick a super complex password and stick with it because we have bots that telnet to the switches and pull configs and make config changes.  I do NOT wish to have this enforcement turned on for these switches and I think it should be an option but neither the Admin Guide, the command line, nor the GUI seem to have any mention of this "feature".  how to disable this feature?

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 ( date  19-Jun-2011 time  18:10:49 )

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?

Cisco :: One UserID / Device Login Required On Wireless 5508

I am deploying Cisco 5508 with Cisco 1602 Access Points at one of my client's office. User authentication will be done through Microsoft IAS Server working as RADIUS Server. There is a requirement from my client is that the user over wireless can only be able to login to One device using its user ID. I want to inquire if this can be done through WLC or it can be restricted on the RADIUS server? Looking forward for comments.

Cisco Switching/Routing :: SG300-10 See All Traffic From All Connected Devices On Any Port / Where To Connect Listening Device

Dec 20, 2012

In my LAN environment, I'm using two cisco SG300-10 switches. Both switches are connected by GE10 on both switches, where both ports are set to trunk.Now on all ports 1-9 on both switches, I'm having client computers attached. So I set ports 1-9 to "access" mode.All interfaces on any switch is left in default vlan.
Is it normal that I see all traffic from all connected devices on any port where I connect a listening device?What I'd like to achieve is, that only traffic that is meant for a specific workstation is actually forwarded to this workstation. By now it seems that I get all the traffic from everybody.

AAA/Identity/Nac :: ACS 5.4 - Change Password On Next Login Does Not Work With SSH

Nov 25, 2012

As observed ACS 5.x " Change Password on Next Login" Feature does not work with SSH Clients ( tried with X-sheel, Secure CRT, Putty etc...) , however through telnet session to IOS devices, users can change their password on their next login.
1: on ACS 5.x i create a new user & Set " Change password on NExt Login" option.

2: Logged into the device through Telnet & Password can be changed after i authenticate successfully. however the same is not happening when i login to the devices through SSH.
is it because of the fact that SSH is encrypted session ?
Because changing password through a telnet session is not accepted in many fanancial organizations as per PCI Standard.

Cisco Routers :: RV042 Main Login Password Has Expired

my RV042. The main login password has expired but it will not let me change it at all. Basically I try to login but get the error 'The old password has expired. Please change the password'. But with no prompt at all for a new password and just a return to the login page. Tried various different browsers, tried the old default password but nothing will work. There seems to be no way of changing it and I cannot login.
I really don't want to reset it to default as I have numerous VPN tunnels configured and various other settings.
