Mar 25, 2012I have a SG300 switch working in layer 3 mode. I created 3 VLANS and the intervlan communication is working fine. I want to know how to block acces to switch managment from the Vlans. One of the vlan is allowed to access the switch but not the others vlans. What is the best way to implement this? with ACL or with Managment Access Method, creating an access profile?
View 1 Replies View RelatedCisco Switches :: Accessing SG300-28P Via Management Interface?
Dec 21, 2012I have a new SG300-28P, and have had occasional issues with being unable to connect to it via anything other than the serial port. I have connectivity between my machine and the switch (tested with ping each way), and in fact, have the same problem if I take a laptop to the switch and connect them directly.What happens is that though the switch is operating normally, http, https, ssh and telnet attempts to access all fail in one way or another. Ssh and telnet either yields no response or a refused connection (even though those services are enabled). For http and https, I'll occasionally get enough of the web page to be able to tell what it is ... but attempts to log in just don't work.While this is happening, the CPU and packet load on the switch is very, very low.Rebooting didn't work entirely, though it may have made it better. Resetting to factory defaults and then reconfiguring makes it work.This is using the latest firmware: 1.2.7.76.

Jun 13, 2012How to set the management interface on a SG300 Switch in Layer 3 mode? I've some vlans configured on the switch with interfaces in each of them:
Vlan 100 (10.0.1.254 /24)
Vlan 200 (10.0.2.254 /24)
Vlan 300 (10.0.3.254 /24)
...
Vlan 900 (10.0.9.254 /24)
Now, the management interface is listening on all interfaces (IPs). But I would like to configure the switch to only listen on 10.0.9.254. What I need to configure or whether it is possible?
Cisco Switches :: SG300-28 GUI Different Than Online SG300-48 Simulator
Aug 29, 2011These 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

Cisco Switches :: SG300 Switches Have Poor Performance In Layer 3?
Jan 1, 2013We 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.

View 2 Replies View RelatedCisco Switches :: Multiple VLANS And SG300-28P Switches Setup?
Aug 20, 2012I'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 :: SG200-18 Switches With LC Single Mode Fiber SFP's
Dec 2, 2012We have a project in which we are using 34 Cisco SG200-18's each with a MGBLX1 (LC Single Mode Fiber) SFP mini-GBIC.All the fiber's come back to one building where we must "bridge" all 34 fiber connections. What hardware should be used to accomplish this? A L2 switch? For example, a 12 port SFP Switch with Fiber SFP's accepting the first 12 fiber connections, then other switch with SFP for the next 12 and so on, until there is a overall capacity of 36 and having patch cables between the 3 switches?
what cisco or non cisco hardware would work with these SF200-18's to accomplish this?
Cisco Switches :: SG300-52 Multiple Lags Between Switches?
Jan 19, 2012I'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 24, 2012I have a stacked Cisco Catalyst 3750 configuration that currently has one V LAN configured. VLAN 192 - 10.192.0.0/16
The Catalyst has an ip on this range of 10.192.0.1. I would like to configured a few more V LAN's to be able to run some more network ranges through this device. Would it be a case of just adding the V LAN's to the master and then configuring an IP for each V LAN within the inter-v lan routing section? Some V LAN's will require access to each other but not all.
Cisco Wireless :: 2112 One Ssid To Multiples Vlan Without Hreap Flex Connect
May 22, 2013I have one cisco wlc 2112 with ios 7.0.230.0 with license to support 12 access points. My access points are nine (9) lap1231ag and one (1) lap1310.I just have one wlan (ssid). My scenario of deployment is in layer 3. I have one interface management and ap manager in the WLC. All my Access Points have differents ip address that WLC. I need to configure a unique ssid to associate my six (6) dynamics interfaces (each dymanic interface with different vlan subnet).Each wlan profile (ssid) should have the same security in phase 2 (wpa2/psk). My cisco access points don't support hreap. My wlc support only (4) interface into an interface group, and i need six (6) dynamics interfaces.

Jan 27, 2013We 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.

Mar 15, 2011I have a question about ACL and binding. I have a SG300 28P and a couple of other linksys switches and Access points that are connected to it via trunks. 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?

View 9 Replies View RelatedCisco Switches :: SG300-10P SYN Protection
Mar 1, 2013Yesterday I upgraded my SG300-10P to firmware 1.2.7.76. I was curious about the new SYN Protection feature, but it seems to do nothing on my installation.
The switch is running in Layer 2 mode. I have ACLs in place and DoS prevention is not enabled. I also tried clearing ACLs and enabling DoS prevention. As I understood the Admin Guide enabling DoS in the Security Suite Settings is not necessary for using the SYN Protection.
In my firewall I see about 300 pps with SYN flags only arriving. What "they" do is sending me SYN packest to port 80 from forged IPs, so that my system should send SYN-ACKs to the victim system. In this case it is the Arab Bank. They are down at the moment...I think that is called a spoofed SYN flood attack.
So I thougt the SYN Protection feature should exactly solve that problem but it does not and does not show any "Last Attack" entries.
If I put a SYN filter in place it works, even if I put SYN Rate Protection in place. But that is just a dirty workaround. My firewall blocks those SYN packets with a SNORT rule.
Cisco :: STP With Switches Linked By Single Hub?
Sep 28, 2012Question: how would STP or RSTP behave in a star topology with a hub in the middle?i.e. you have four switches all linked to the same central hub. Single links, no loops.Each switch would then get BPDUs from everybody.Going by theory, it should be OK since it still sees the root's BPDU and will see the link to the hub as the root port, despite presence of other BPDUs from other switches? No different from receiving an inferior BPDU from an upstream switch and a superior BPDU from a further upstream root switch.I guess I could lab it by turning off spanning tree on a switch to simulate a hub? I've never previously had to deal with STP issues where there are hubs that aren't strictly point to point bridging so to speak (ok they're not bridging but you get the drift).I've got a scenario I'm examining at the moment where this is the topology, except all switches have bpdufilter running hence effectively no spanning tree. I'm curious to know what would happen should I remove the bpdufilter.I realise there is zero benefit in spanning tree in this instance as I don't have any redundant loops to fall back on, but I'm reluctant to turn off STP on those vlans (since obviously theres stuff behind those switches). The BPDUfilter method seems like an elegant solution but I wonder if its actually necessary.(the hub is actually a VPLS mesh, most sites terminate PE to CE router but I'm playing around with switches as the termination points – run our own Q in Q, split vlans off before it gets to layer 3 as separation, etc.)

Feb 7, 2013I have an SA 500 with the optional port configured as the DMZ. The LAN ports are running the 192 range and the DMZ is the 172 range.
I have seperate offices (A few hundred feet apart) that have been connected with 2 un managed switches up linked with a single wire. The 192 range stuff runs over this. I need to get the DMZ out to the second room and was asking about how to do this over the single up link and switches. (Trying not to run a second wire)
My lack of understanding had me draw up this diagram attached as a picture, to ask about. What it shows is me trying to get the DMZ through the up linked switches to the other room. I thought of using 2 routers, one on each end. I've been told this is incorrect and wont work.
Maybe a purchase of a second hardware and eliminate the switches? (up link the SA 500 to another device?) What should that device be?
