If switches on a network doesn't support remote port mirroring and only local port mirroring, What are the options to still capture all the traffic from all switches on 1 single core switch?

View 3 Replies View Relatedi 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).
i have also tried to return to default factory setting but this does not solve the issue.i am working on SF200-24P
I 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?
I 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.

View 1 Replies View RelatedI'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.

View 7 Replies View RelatedRecently 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.

I have decided to buy a new wireless N enabled wireless router after my house was cleaned out by some robbers. After a long investigation I decided on the D-link DIR 655 as it suited my basic needs the best and since I haven't decided on a broadband supplier yet this should sort any and all possibilities no matter what I choose...
After an equal amount of investigation I decided on a HSPA+ USB dongle only to find that the router does not support the network I have purchased it on. It thenalso seems that it doesn't support the E1820 Huawei dongle either... so fine... I go and buy a Huawei D105 tht should technically be able to connect via the WAN port and would act as an internet gateway. Brilliant.
Now I have tried everything.... static IP on the D105 with a static IP setup on the 655. Connects fine... according to the web interface but NO INTERNET. When I connect my laptop directly to the 105 via CAT5 it works beautifully. DHCP on the D105 with the same on the 655. Connecting... Establishing Link (Please Wait...) FOREVER without ever getting an IP on the 655 (according to the web interface again) ... must be the D105 thats faulty so again plug in the laptop and within milliseconds the IP is assigned and Internet is blazing along again.... The D105 is not Wireless N so I cannot use it as my primary AP and only allows 5 simultaneous wireless connections (that is reserved for my cellphones). Why should I anyway?? the DIR655 should work fine....
Even after having taken it to D-link support at huge cost and effort I still don't have a working rig.... Seems the consultant plugged the D105 straight into the LAN on the 655 and then set his laptop to the same static range to get it to work... SURPRISE - I know that works since plugging the laptop straight into the 105 does the same thing.... But this is not what I want... I want my 655 to be the primary DHCP server for my network and control the allowed workstations that are allowed access to the internet with a working gateway. Bridging is apparently also not an option as that option has been removed so I cannot even bridge my main subnet onto the D105's internet sbnet... What am I to do....
If the 655 3G setup supported more than 2 dongles I might hve been able to use that and not spend anouther R600 on the D105, if the WAN port actually worked in either static or DHCP modes with the D105 that also would have solved the problem and lastly if all else fails and there was still bridging I could hack my own setup together to do what I want. Seems like I was wrong in selecting the D-link product.
Then to make matters worse I find another product with double the features online for half the price that integrates the 3G capability into the route and support more than 2 different models. including all the new Huawei dongles....

View 3 Replies View RelatedI've just installed 2 of these in my workplace on a PLC network.I'm now looking to set one of the ports up as my diagnostic port and would like to be able to mirror any of the other ports to this port.I believe it is called SPAN on Cisco switches.The only reference I can find to it is configuring via Telnet which I haven't got a clue about.On my old Wiedmuller switches it was just a few clicks away.

View 5 Replies View RelatedI 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.

View 2 Replies View Relatedwe have three separated network segments going to one Cisco 3750 switch all is L2 .. from this switch is 100 mbit uplink.we need to apply some Qos mechanism not to saturate line by traffic from one network.. Configuration from various reason CANNOT be done on switch where 100Mbit line is terminated.. so all must be done on SW1,2,3..Correct me if iam wrond but as switches doesnt see traffic from other network iam affraid only think we can do is limit bandwidth on links going into SW1,2,3 to 33 Mbit.I found commad srr-queue bandwidth limit.But links going to SWs are 1Gbit so if i force bandwidth to 10% (minimum what command allows) its 100 Mbit..If I force speed on those links to 100Mbit and than apply srr-queue bandwidth limit to 30% doest it work.??. Will srr-queue bandwidth limit speed to 30Mbit?? Or srr-queue bandwidth limit is calculated from maxim speed of interface?

I looked in the router setup to find my current public ip address from Comcast say its 98.221.99.99. If I am on the same network as the machine that is receiving the port forwards, and I type http:// 98.221.99.99 in a browser, the forwarding works fine.If I am external/not on the same network, typing http:// 98.221.99.99 in a browser times out. I have tried http:// 98.221.99.99:9000 too (9000 is the port I need forwarded) and that doesn work either.But, I do have remote management enabled for the router and if I am external/not on the same network and I enter http:// 98.221.99.99:8080 in a browser, I get the router login screen and can enter my user name and password and login to the router just fine.
View 11 Replies View RelatedWe recently moved 8 pc's from a room where they each had port on the switch to a room where there is only one port for all of them. I setup a DLINK DIR632 Router in there and they connect thru the one port thru the switch to the gateway which gets them out to the internet.The problems is I need to be able to remote desktop into these 8 PC's and I need them to be able to print to the network printer. I am using a Linksys WRT54G Broadband router as the gateway connecting the switch to the internet. The DLINK's dhcp server is on for the 8 PC's. The Linksys' dhcp server shows the DLINK as IP 192.168.1.19 on the network.I know I have to use advanced routing settings but I'm not sure about how what to make the subnet mask and IP's on both routers. I believe I need to turn off the dhcp server on the DLINK and have the Linksys' dhcp server serve all of the PC's but I'm not sure if thats the best way or if its possible.. I don't want to hack out fix only to find it breaks 3 days later.I used to do this stuff all day long in the 90's but its been a while and to me its like calculus.
