SLM2008T does not have the ability to add Port Description or Login Banner like the SG300's do? I knew there would be some features that the 200 would lack, but I've never seen a smart switch that did not have the capability of labeling the ports via software/web admin. Really makes it easier to keep your head screwed on straight when you are in and out of 14 or more switches during the course of a day.
View 4 RepliesI've just gotten a SG200-08 (SLM2008T-EU), which I would like to monitor remotely from Cacti using SNMP. It seems however, that this switch has no SNMP support - is this correct? Does this mean that there is no way to monitor traffic over the switch's ports short of making a script access the web UI?
View 1 Replies View RelatedI recently bought a SG200-08 8-port gigabit switch. The switch firmware is the latest (1.0.0.16). Everything works fine, except that packet loss I have when flood-pinging on the LAN.
I have 3 machines connected to the switch, they have 1000 full duplex links, they all have Ubuntu Linux installed on them, no limiting on the switch (as far as I can tell), no limiting on the machines (nothing like htb, cbq), no QOS set up on the switch, the machines are fairly OK hardware-wise (dual-core, quad-core, six-core). And still, it doesn't matter which way I ping, I get a consistent packet loss of 5-7% when flood pinging:
gimre@voy:~$ sudo ping -n -f 172.16.21.4 -c 10000 -q
PING 172.16.21.4 (172.16.21.4) 56(84) bytes of data.

I recently saw a Cisco demo of ISE with a customer and the Cisco SE was setting the port description to the logged in username (dot1x). I can't find any docs on doing this. I did find some old ACS docs that mention using an AV pair and sending aaa:suplicant-name in the result, but that isn't working. I'm trying this on a 3750. and using ISE.

View 1 Replies View RelatedI have 2 switch groups.
2 SGE2010's with VLAN's defined as 10,20 and 30
Vlan 10 is the management VLAN, and it uplinks to our border router.Vlan 20 is the workstation VLAN, and all workstations point to the switch as their default GW? Vlan 30 is the ip phone VLAN, and all phones use this as their gateway.
I would like to put a LAG between said switches, we have some servers on the ip phone switch that need to be accessed by the workstation clients, and the single 100mb link through the router is probably not going to be enough.As I understand it, because the switches have different networks on them, a simple lag will not work. I did create a lag, and assign ip addresses to each side, however in that mode, it doesn't appear I can block vlan 10 from transiting the LAG, and with out that block I will end up with a logical loop, and spanning-tree will block one of the uplinks, or the LAG itself.
i 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 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 just bought 4 units of Cisco ESW-520 24Ports switches. I did some testing and found out for PORTS 1 and 12 is in "Suspended" mode and thus not able to use.This not happened to 1 but all 4 switches. Why is this so? How to disable the ports from going into "suspended" mode automatically ? I wouldn't want the ports to be in "Suspension" mode when it goes live and thus block the desktops from having internet access.

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.

The issue I have is that I can have either a phone or a PC plugged into a port but not both. If I plug in both then the phone works and the PC gets an IP address (Broadcast traffic) but PC cannot browse the network.
We just purchased 8 managed switches POE to swap out our existing in preparation for our new phone system. We installed them all after configuring with static IP. Deployed... and all but two work fine. Any tips for troubleshooting why two of them do not work? There are a couple other switches in the building. Could it be that a switch "upstream" from the two non-functioning switches is causing an issue? If so, how do I find out? When we put back the two "dumb" switches all was fine.
View 1 Replies View RelatedI'm having troubles setting up a separate VLAN for wireless on a SG-200-26. My first question is why did Cisco not make the VLAN setup like they have all their other business class switches? Anyways, the Access and General modes on these SG class switches are throwing me for a loop.
Right now I just have one port (g10) on the SG-200 switch that needs to be in VLAN 6, which is our wireless VLAN. All other ports are in their default VLAN, which is 1.
Here's what I've done...
Configured port G1 (trunk to another switch) as the trunk port and Port G10 (attached to WAP) as a general port. All other ports stayed in their default configuration. This is what it looks like now...
Port Mode PVID Operational VLANs
g1 Trunk 1 1U, 6T
g2 Trunk 1 1U
[Code].....
I'm pretty sure port G1 is configured correctly, but I have no idea about what port g10 should look like. Common sense tells me it should be an Access port and assign it to VLAN 6, but apparently you cannot tag the traffic within an Access port on SG switches, which makes it useless because how will other switches recognize what VLAN the packets are in? So the next logical mode would be General mode, which I put in VLAN 6. I switched that port from being 6U (untagged) to 6T (tagged), but neither seemed to work.
VLANs on SG switches, how port g10 should be configured for VLAN 6 traffic.
I have an ESW 520 8-Port switch with a management ip address of 192.168.10.2 /24 After I reboot it, I can successfully ping it from a pc with an ip of 192.168.10.123 for about 50 consecutive times.After that, I get a "Destination host unreachable" (this icmp message is sent by my pinging pc (192.168.10.123).This obviously seems like a bug.Whenever I reboot it, it goes through the same sequence.
View 2 Replies View RelatedI just purchased 2 SF-300 48 port units for 2 customers. I want to be able to remotely manage them over the Internet with my browser. BUT, customer sites already use port 80 for web servers. So, how do I configure this switch to use some other port than 80?
I called support, and much to my surprise he said it cannot be changed. How bizarre that a device with many hundreds of configuration settings does not have one of the most basic settings...
At one customer site I can configure port forwarding and translation to get around this problem, but the other site's router does not offer port translation..
Our 6509 has seen better days and we know it's past time to replace it... Question is - go with similar or just use multiple 48 port switches? Then we have old Cisco 2800s in our 9 IDFs that would need updated as well.
We have a mixed environment with about 300 active clients along with about 15 servers and an EMC AX4 over 4GB fibre brocades for backup.

View 1 Replies View RelatedI have 5 VLANs, I assign VLANs to its ports and make them all Untagged.I created ACLs and a ACE rules for each ACL, and then assigned to the ports.So what i am trying to do is to deny access to from one port to other 4 ports and granted access to any other ports. But it is not working, without last rule "allow any any" it has no access to any ports, with the last rule it grants access to every port even to those I denied.Router in Layer 3 mode, all VLANs have their IP's.
At some moment I was able to work it properly but without using any rules, I just tagged my untagged VLANs to those ports which I wanna get access to. As you can see I want allow ports GE1 - GE4 communicate with 1 to 24 ports but not to each other.
I'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?
I have a sge 2000 24 port POE switch that won't boot, won't communicate on console or TCP/IP, and all of the port lights are lit up green. Holding down the reset button doesn't fix the issue and there aren't any lights illuminated on the left hand side of the switch.
