What i am trying to achive is allow only specific mac addresses on switch and deny all others by using MAC ACE. What should i do? First deny any any and then permit or ?
View 1 Repliesi have a SG300-52 Switch, route mode is enabled, and it is using the latest IOS.I have created 4 Vlans in this switch, till this point its OK, but once i try to give ip addres to the created Vlan either from the GUI or CLI the switch is not responding. i have to go and manually reset the switch using a pin.

Low and behold the SG300-28P is sending out quite a few Broadcast Packets. Most of them are the same, ARP Request for its Default Gateway Address. Others are for a few other AD Servers on our network.
Arp Entry Age Out is set to the default of 600000 with "Normal Age Out" selected. Though in a few minutes of logging Packets, there were almost 7,000 broadcasts from it for the its Gateway Address. The Gateway Address that it has is the IP of a Cisco ASA 5510. Is there some TTY on the ARP entry like DNS?

I have just purchased a SG300-28P switch I am using a GUI to do my config. I cant create VLANs just fine on this but I can not assign IP address to the VLANs.
I just want to have a Data and Voice VLAN on this I am planning on leaving data on VLAn 1 but I can't seem to find an option to assign an IP address to my voice vlan.
For some odd reason I cant access this switch using a console port.
I am trying to assign static ip address on vlan 1 interface , the model no of switch is SG300 & the firmware version is 1.1.2.0 .But whenever I type the IP address & press enter , a question is popped up asking for confirmation (switch0d851f(config-if)#ip address 1.1.1.1 255.0.0.0.
Please ensure that the port through which the device is managed has the proper settings and is a member of the new management interface.Would you like to apply this new configuration? (Y/N)[N] N )
I use a router RV082 with load balancing. My problem is when I try to access a specific site, I get the error message that my IP address changes and I can not use 2 ip address. I want to specify an ip range to always use the same WAN port.
View 2 Replies View RelatedIs it possible to enable an absolute value rate limit using QOS on a HP ProCurve 5406 switch for a particular IP range on a specific port? Is there a way to configure our HP 5406 with an absolute rate limit on "WAN" port for that server's IP range? I would like to limit it to only being capable of sending 1Mbps worth of traffic over the head end at once.Everything in the documentation points towards priority queues, which as far as I can tell, isn't really what I want.Baring accomplishing this goal using rate limiting is there a better way to prevent our services from accidentally saturating this connection?i thimkong about somthing like that:
class ipv4 rate-limit-port-A1
match ip 10.136.0.0/16 any

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]

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?

View 8 Replies View RelatedI'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?

View 6 Replies View RelatedWe 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. I already have a Cisco SGE2010 on my network without problems.
View 7 Replies View RelatedI 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 RelatedYesterday 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.
I'm trying to get started on setting up my first Transparent ASA.I understand an ASA in Transparent Mode can now have an ip address with Bridge Groups or some such mechanism. I'm looking for examples of how to set that up and other information below. Is the ip address associated with the device or is it interface specific? Will I be able to SSH with that ip address setup? Can I use ASDM if the Transparent ASA has an ip address? This 5512X has an IPS. Any one who has setup an IPS on this platform knows it has some very particular requirments in order to communicate with the outside world. I need examples of how to do that with a Transparent ASA.How is NAT setup differently (if at all) on a Transparent ASA?Are ACLs done any differently?
