Cisco Switches :: SGE2010 Stacking Compatibility With SG500
May 29, 2013I am currently running two SGE2010 in stack and planning to purchase new Sg500 .I have two questions :
1. If these two different products can be managed as one stack.
2. Are the SFP (mini-GBIC) connections compatible and if so what accessories or parts do we need to enable them?
Cisco Switches :: SG500 Stacked Switches Getting Errors?
Dec 16, 2012We have 3 SG500-52 switches that are stacked and configured for layer 3 that replaced a couple of SG2010 switches a month ago. Switch units 1 and 2 are for servers and unit 3 for the workstations. The switches are connected with stacking SFP+ copper cables, 1 1M and 2 7M cables. The problems are occurring between the workstations and servers resulting in slow traffic on some links and connection failures. A repeatable failure occurs doing a backup from a PC on unit 3 to a server on unit 1 and 2 (2 port LAG). Moving the workstation to a port on unit 1 results in successful backups every time.
Initially I was able to confirm packet loss between my PC (on unit 3) and the servers using ping (ping -f -c 100000 -s 1460) of about .1%. The iperf program in udp mode also showed some packet loss and in tcp mode showed slow connections. A week ago I then upgraded the switches from v1.2.0.97 to v1.2.7.76 and rebooted. After that the ping and iperf tests show no problems although there are still slow connections to samba shares and the backups still consistently fail.
I suspect there is a problem with the stacking connections and have searched for traffic statistics on the stacking ports to look for errors but have not found anything. Doing a snmpwalk didn't reveal anything that I recognized. There are interface counters for all the ports except the stacking ports.
Cisco Switches :: SG500-28 Stackable Switches And NIC Teaming
Apr 17, 2012Am looking into using stacking and NIC teaming to create redunancy for user access to servers. What I am thinking is getting 2 SG500-28 switchs and configuring them in a stack that appears as one logical switch. Now on the servers I would configure 2 NICs to be a team so they appear as 1 logical interface, perferably in an active/active configuration using LACP. In this NIC team take 1 team member to switch A and the other to switch B, so each team member is on seperate switches.
Givent the scenario:
1) Will that work with the 500 series switchs? Reason for the switches is their price point is perfect for my client.
2) Besides the stack link will there also need to be a LAG between the switches or does the stack link do data traffic also?
CIsco Switches :: SGE-2010 How To Wire Switches For Stacking
Dec 13, 2011We had a SGE-2010, just purchased 2 (two) SGE-2010P. I want to stack the switches (all 3) (unless there is a better way). Not sure what is needed hardware wise, and how to physically wire the switches. Had switches years ago (diff brand) that used a special cable that connected the switches. It seems that is not the case here. I have not used fiber in networking before so I am new to that part, I’m willing to learn, just need pointed in the right direction.Can all three switches be stacked, (1) SGE-2010 & (2) SGE-2010P? I THINK I need to use the GBIC port 4 to stack, I understand 1 port is enough if two switches are used, but what about three or more switches.What are the other GBIC ports used for? Will I be better off (can I ) use the GBIC ports LAG (2 ports) to the other switches? Or would regular ports work just as well?

Apr 25, 2012We have a scheduled office move where we are consolidating 2 remote offices into one. I’ve been asked to spec out the correct size UPS to support all of the network equipment for this new office.I went to the Cisco website and I see on the datasheet for the switches and router where they talk about the wattages and BTU’s but how can I go about deciphering from that information what my total wattage and BTU will be for each switch and router?What numbers should I be looking at? For instance, we have 3 3750 48 port PoE switches. So if I look at the datasheet for that switch they have 4 different columns, one for 100% throughput power consumption, one for 5% throughput, another one for 100% throughput for max PoE load and one for 5% throughput with 50% PoE loads?Is there a common method for deremining UPS requipments? For the switches I pretty sure I need to assume max PoE load in the event every port has a phone plugged into each port.
View 3 Replies View RelatedCisco Switches :: ESXi Management Not Working With SG500 LAG
Jan 8, 2013I am setting up a 3 host ESXi cluster. I am using a pair of stacked SG500-28 switches for switching redundancy. Each host has 8 NICs. 4 to each switch. I have successfully setup a 3 NIC LAG with 1 path to one switch and 2 paths to the other. These LAGs work. When I setup a 2NIC LAG via the console for management, and the associated ports on the switches, I lose managment communication with the host. Before setting up the LAG in the ESXi console, I set that vswitch properties to us IPHASH as instructed here bit.ly/VLaTEt I have attempted to follow those instructions as closely as possible. The one thing that I am wondering is whether the SG series supports etherchannel. I can't find any reference. Either way, it works on the other vswitch that is for vMotion. I can vmkping between the hosts over that LAG. But setting up a LAG on the management vSwitch doesn't?

Cisco Switches :: SG500-28P Does Not Handle NLB In Unicast Mode
Apr 8, 2013We have a problem with NLB on a SG500-28P which is a major issue for us.
I am investigating a problem together with Microsoft Support about a download/upload performance issue with a Microsoft Forefront TMG array which is connected to a single SG300-28P. Àpparently this issue exist on every NLB array we implement. I am now at the point we asume the SG500-28P does not handle NLB in unicast mode very well.
We have a network topology as shown below:Please note the actual public IP Addresses are hidden and the internal IP Addresses are diffrent, for security reasons.
Our SG500-28P is configure in L3 mode. It hosts three subnets you see above. The two TMG servers are configured with NLB (in unicast mode) on the Internal Network and External Network interface. It is connected to the internet and our internal network. These TMG Servers are in fact Edge Servers. Our other servers and client are in a different VLAN. The default gateway flows through this NLB Cluster [10.250.0.254].
Problem: When a client uses its default to connect to the internet the performance is very and very slow. With an internet connection of 10/10 we get 10/2. With an internet connection 100/100 we only get 7/1!.
Now we have tried everyting we can imagine. I can't write down all, because that would be a lot. One thing is worth notice; When we move the client to the same VLAN as the NLB Cluster and the client uses 10.250.0.1 as its default gateway, the problem still exists. But... when the client uses 10.250.0.254 as its default gateway the performance is outstanding 95/95! Apparently if traffic for the NLB Cluster is routed through the SG300-28P the performance drops like a rock.
I have never seen this before with SG300 series switches, although this environment is different. Normally I would configure NLB in multicast mode. But the switch does not allow to add static ARP entries for multicast MAC Addresses.I know NLB in unicast mode introduces switch flooding and such. But why does the SG500 not handle this right? Is there anything I can do about it?
Cisco WAN :: SG500-24 - Switches Between Cable Modem And Router?
Feb 25, 2013Currently, my Cisco DPC3010 cable modem is connected directly to one of the Ethernet ports on my Linux router. All works quite well that way. However, I'm curious to know if there's some what to separate the router and cable modem over 2 switches?
The coax enters the house in my living room and connects to the CM there. The router is also sitting in the living room, and it's connected to a Cisco SG200-18 switch. I have Ethernet running from my living room to my basement, where a Cisco SG500-24 switch sits. The two switches are connected via a 2xGigE port channel.
I want to move the router into the basement. Ideally, I'd like to move the CM down there with it, but I don't have the necessary coax run. So for now, that's out. But... can I go from something like this:
--coax----- Cable Modem ---GigE----- Router ---GigE---- SG200-18 ===2xGigE==== SG500-24
To something like this:
--coax----- Cable Modem ---GigE----- SG200-18 ===2xGigE==== SG500-24 ---GigE----- Router
I tried it, complete with a separate VLAN specifically for the CM traffic. And the VLAN was properly trunked between the two switches. But for some reason, the router was unable to communicate via IP to the upstream. I'm not sure if there are config bits I need to set on the SG200 that the CM is connected to? I thought I'd read somewhere that CMs don't like broadcast technology such as LLDP and/or CDP, so I disabled both of those on its port. Did I miss something else perhaps? Or am I trying to do the impossible?
For what it's worth: the IP connectivity is static. There's no DHCP running between my router and the upstream cable provider. The cable modem is literally acting as a L2 coax-->Ethernet convertor, more or less.
Cisco Switches :: SG500 Possibility To Bind ACL To A Virtual Interface
Mar 24, 2013I have a switch from SG 500 Series the works as Layer 3 Routing Switch with the Firmeware 1.2.7.76. I have create some diferent VLAN´s and have defined one ACL for each VLAN. Now i try to do a binding from the ACl to a VLAN but i have only the option to bind the ACL to a phys. Interface or a LAG.is the a possibility to bind the ACL to a virtual interface like in other Cisco serieses and how it works ? the Backround is i have connectetd 2 Hyper-V Server where the Guests are in different VLAN´s and the server is connectetd with a 10Gb Trunk to the Switch now the switch routed the different VLAN´s and i must have some restrictions between the VLAN´s.

Feb 26, 2013At our office we have a weird performance problem with the following switches and connectivity:
Internet |
SG300-24 (L3) core switch (in our server room)
|SG300-10P (L2) access swtich (in our meeting room) |
SG500-28P (L3) switch (in our meeting room)
We are building a new computer infrastructure that is connected to the the SG500-28P. As you can see above the SG500-28P in our meeting room has an uplink to the SG300-10P in the same meeting room. And again the SG300-10P has and uplink to the SG300-24 in our server room. From the server room, there is connectivity to internet. The network uses a multiple VLAN's and routeing between them. Bootom line is, the internet VLAN ID 10 is tagged to trunk ports and available on the SG500-28P. So client get connected straight into the internet based VLAN.
The performance on the SG500-28P switch itself from VLAN to VLAN is very fast. But... the uplink connection tot the internet and other VLAN's on the core switch are very and very slow! At least 10 times slower than normal. So if I plug a laptop in the SG500-28P and go from uplink to uplink, it is slow! But... when I connect the same laptop to the SG300-10P the connection with only one uplink it is fast. As if three switches is to much. I can't figure out why.
Cisco Switches :: From SG500 Port Appears Up But At SG200 It Is Disabled
Jan 4, 2013I have an SG-200-8 which connects to a stacked pair of SG500-28P switches. It is powered by PoE from the SG500. From the SG500 the port appears Up, but at the the SG200 it is disabled and nothing I do re-enables it. I know the cable is good because I had a previous netgear switch hanging off it and working, also the power gets through.I can only connect to the switch if I disable wifi and plugin a manually configured PC - DHCP doesn't get through to it from the SG500 end.I have tried a second SG200 same problem. Have disabled RSTP/ STP thinking it might to relate to the fact that a PC connected to the switch also had a wifi connection to the same LAN, but. Don't know where to go next. looks like a bug?

The swtich is configured and going to operate in L3 mode. All ports are still assigned to the default VLAN ID 1. I have created several new VLAN's. Once I configure and aplly an IP Interface to a certain VLAN the swtich becomes inaccessable right away. I am pretty sure I am not pulling my own VLAN under my connection. Every port is inaccessable. I have to pull the power plug and restart the swtich with its saved configuration. Even when I add another IP interface to the default VLAN 1, same issue. I have tried lot's of things, but can't get it to work properly. I have just upgraded to the latest firmware.
I have configured dozens of SG300 swtiches which is very easy. This one does not work with me.
Cisco Switches :: SG500 - Migrate From Default VLAN1 To Different VLAN
Mar 1, 2013I have an SG500 that is already deployed with some Access VLANs on it. The PVID is still the default 1. I am trying to change it to 19 with as little interruption as possible. If I just go to the VLAN Management Tab and change the Default VLAN to 19 and reboot the switch, will it migrate my management IP to the default VLAN without any trouble? Would it be less interruption to: Create VLAN 19, assign it an out of subnet IP address, change a port to PVID 19, connect directly to that port, go to that IP address, remove the original management IP from PVID1, change all the ports to PVID19 then change the management IP back to the original?

Cisco Switches :: SG300 Stacking And Powered From POE By Upstream Switch?
Sep 11, 2012I discovered on a pair of SG300-28P.
On a second switch (ver 1.2.7.76) when I unplugged the power cord, to my amazement the switch turned right back on (about 1 second later), with the power cord removed. To verify that the power is indeed coming from POE, the upstream switch (ver 1.1.2.0) that is the same model (sg-300-28p), shows all 7 Ethernet ports connecting the two drawing from 2700mW, to 3000mW.
While the second switch is powered from the first over POE, the POE does not work on the second switch to power anything, and the system summary mentions something about "PoE Power Information on Master Unit".
Is this a stacking operation, and is POE on the second switch NOT supposed to work when powered over Ethernet from an upstream switch?
