Cisco Switches :: Getting SG300-28 Port Mirroring?
Apr 28, 2013I have created a mirror to copy all packets from Interface gi1 to interface gi28. I don't see any port 80 traffic, or 443 or any revelant traffic. I see mostly broadcast from other devices. I have a security device that is logging all the copied packets from my firewall for malware/IPS, etc inspection.Right now I have it monitoring vlan 1 in the hope that it would resolve this issue but I see no change.

Nov 8, 2011I'm troubleshooting a LAN issue I have, and I wanted to hook up wireshark to record traffic over the course of a couple of hours for later diagnostics. I went into the web administration interface, clicked Administration > Diagnostics > Port and VLAN Mirroring, and added a port mirror from the port I wanted to watch to a port to which I had connected a laptop. I picked the Tx and Rx options, and clicked Apply.I did receive lots of traffic in wireshark, but I noticed immediately that the server on the port I had mirrored was suddenly unavailable on the network -- pings timed out. This lasted until I removed the mirror, then the server was suddenly reachable once again.Does this feature not work the way I had thought it does? What I saw looked more like a forward than what I would call a mirror. The documentation leads me to believe mirroring is intended to be used in just the way I was attempting to use it.

Mar 14, 2013i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.i have supressed this port mirroring.when i try to reconfigure a port mirroring from port FE17 to FE3. The SF200 web interface crash. the SF200 seems to reboot.
i have updated the SF200 firmware from V1.1.2.0 to V1.1.2.9.44 when i was able to configure (via SF200 web interface) a port mirroring from port FE17 to FE7.But after having suppressed this port mirroring again, i was not able to reconfigure a new port mirroring from port FE1 to FE3 (the SF200 hangs).

Cisco :: Port Mirroring On Switches?
Oct 31, 2011I have a Cisco Catalyst 3750X switch, and I have configured port mirroring on it. Traffic from 12 of the 1G ports will be mirrored to both 10G ports, and I have connected both 10G ports to a server that captures the traffic.
Currently, I have one of the 12 1G ports connected to another server that replays a pcap file once at maximum speed (i.e. option -t in tcpreplay). I thought that this setup means I should get twice the number of packets (and rate) from the two 10G ports. However, I noticed that although the original pcap file contains 4288 packets, the number of packets from the two 10G ports varies between 31000 to 34000 packets, which is about 7 to 8 times the original number of packets. Why am I getting more than twice the amount of traffic, and why does the output vary?
Cisco Switches :: Port Mirroring Limit On SGE2010?

Jan 24, 2013Recently our company purchased 3 Lynksys SGE2010p, At the moment they work as a stack but as we are implementing UCCX we need to mirror 15 ports but during the provisioning i've noticed that the limit is 8 ports per stack. I'm wondering whether this is a known issue or just a known limitation . I believe that most probably i'll need to move back to stand alone mode so i could configure 8 mirrored ports per switch.

Aug 9, 2012I'm administrator of small network. I wish to replace my old switches by new SG300-10 and SG300-16 managed switches. I have big trouble in my network because everyone can assign IP his neighbour (or any IP) to his network card. I have policy that IP is 172.16.1.X with x is home number. Could I do that IP based ACL assigned to port where is cable from home example 29, permit only IP 172.16.1.29 (mas 255.255.254.0) (from specified port only permit packets with specified source IP (LAN user IP) other (if user set not his IP) is denied) ?
I want know that before buying equipment. How to configure that ?
I think IPv4 Based ACE, action: permit, source IP: 172.16.1.x (nr of home), widcard 0.0.0.0, destination: any, protocol: any, source port: any ?
and in ACL Binding, I have to bound this ACL to port where user whose IP is in ALC is connected?

Oct 10, 2012The switch has been set to Level 3 Routing. Port 27 has been in use as a Fiber Transceiver with no problems for several weeks. This week I tried connecting a second Fiber Transceiver to Port 28, and it would not work.
Swapped the physical GBIC modules in the ports, and the situation remained exactly the same: Port 27 works, Port 28 would not work.
Connected to the copper-part of the combo Port 28, it immediately connected and worked fine.
Connected an external Fiber Transceiver Box in place of the GBIC in Port 28, and it immediately connected and worked fine.
Swapped the new Fiber jumper (Port 28) with the existing Fiber jumper (Port 27), and the new connection came up immediately and worked fine. The existing connection would not work when connected to Port 28.
By "not working", I am not able to ping across the connection. The link light comes on and blinks. The transmit/receive statistics show as if data is processing on this switch, but on the other side of the Port 28 connection, the switch shows Transmit traffic, but no Recieve traffic.

Cisco Switches :: SG300 Port Authentication 802.1x No Logon Servers Available
Oct 11, 2012I have configured a Microsoft Server 2008 R2 with Radius Server and connect it with a Cisco SG300 Switch.
If a new device connect to the switch it goes automatically to the guestnet. If a device with the correct certificate and a valid useraccount connect to the switch, the deivce goes in to the local company network.
Now my problem: If I connect a device which is in the domain and which have installed the correct certificate and want to login with a new domain user (which is not cached in windows) I can not login.
The following message appears: "There are Currently no Logon Servers Available"
I think the problem is that the authentication process only starts after a user have succsess logged in in windows.
Now I search for a solution which allows me to conntact the Logon Server for Domain Login before the User has logged in.

View 3 Replies View RelatedCisco Switches :: SG300 Port Counters Via SNMP / Do They Work
May 24, 2013I've got an SG300-10 connected back to back (trunked) with a Cisco 3560X switch, across a fibre link and am seeing some big inconsistencies in terms of unicast data transferred across the ports between them.
During a night time window of 4am - 6am I run backups which involves a large copy of files, that almost saturates a GigE link - we can see from the 3560X end that the link is running at a bit over 800MBit/sec of throughput, sustained. The duration of this transfer is consistent with the size of the files being transferred (ie just over an hour, and is what I'd expect for a data transfer of about that amount). Back-of-the-envelope calculations indicate that the 3560X is measuring this data throughput correctly.
However on the SG300 end of the link, which is also being polled by the same application (Cacti), I'm observing spikey counts of only around 20MBit/sec during that window. These counters are very obviously incorrect - there's a huge amount more data moving across the port than that. The incorrect calculations are showing on both the trunk port out of the SG300 (uplink) as well as the interface where the NAS is connected in (which is an access port).
Cacti is polling the OID: .1.3.6.1.2.1.2.2.1.16.57 which translates to IF-MIB::ifOutOctets.57 = Counter32.I'm running version 1.3.0.62 but this problem is not new to this release - previous releases and 1.2 based releases also had this problem.
It looks like multicast traffic may be being counted correctly (that's only a suspicion though), however what I am certain of is that there is a very large discrepancy with the unicast traffic counts.Is this OID the correct one to be using for this switch?

If I do: #monitor session 1 source interface fa 4 (wan port)
i get the response invalid input detected however if I do the same command for fa 1, fa ,2 and fa 3 they work
Using the ? shows the valid entries are [0-4] for fastethernet

I would use a hub on the Wan connection but unfortunately I do not have one at the moment.
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.

View 2 Replies View RelatedCisco Switching/Routing :: 3548XL Port Spanning / Mirroring With Snort IDS
Oct 30, 2012I am trying to configure a SNORT IDS system running on a physical machine using Linux as the base OS. I have a small lab network setup with 3 VLANs, a 3548 switch and a 2611 router acting as the router on a stick/inter-vlan router. My goal is to setup SNORT as a host-based IDS system. To do that I know I need to use the "port monitor" command on the switch and I have tested this and it works fine only when the snort system and the traffic I want to monitor reside on the same VLAN.My problem is I want to be able to monitor a trunk link betwee the switch and router to see traffic coming from my 3 VLANs which contain servers. My goal is to run attacks on the servers to test SNORT's effectiveness.
Relevant information from my configuration: interface fa 0/1 on switch is the trunk like carry 3 vlans to the router On the switch:
int fa 0/1
switchport mode trunk
int fa 0/5
port monitor fa 0/1
switchport mode access
The switch will not allow me to configure fa 0/5 as a trunk, only can be an access port.So right now, SNORT does not see any traffic other than traffic from my router to the switch. I assume because this is going over the native VLAN (1 in this case) and that is the same VLAN that SNORT box resides on on interface fa 0/5. So I know the span is working to an extent, but traffic from my other VLANs (server to server traffic) does not show on SNORT at all.I have done some research on Cisco.com and see the following seemingly contradicting information:
VLAN Filtering When you monitor a trunk port as a source port, all VLANs active on the trunk are monitored by default. You can use VLAN filtering in order to limit SPAN traffic monitoring on trunk source ports to specific VLANs Then I see, under the section for the 3500 series: A monitor port cannot be a dynamic-access port or a trunk port. However, a static-access port can monitor a VLAN on a trunk, a multi-VLAN, or a dynamic-access port. The VLAN that is monitored is the one that is associated with the static-access port.
My question is, does that mean the 3548 cannot support spanning a trunk link and having all VLANs on that trunk be monitored correctly to the monitoring port? I know the 3548 is old, but it is the only thing right now I have to work with. I could put the SNORT box inline on the network, but that is another mess in itself.

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.
