I 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?
I have a Cisco SG500-52P along with an older SGE-2010P, am I correct that in order to stack they must be the same series?

Currently have several switches in a stack configuration but would like to increase the bandwidth between some or all of the switches. Does stacking support a link aggregation configuration? If so what ports can be used and how should the link aggregation be configured in conjunction with the stacking?

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 looking to buy SGE 2010 swith, but I have some question:
1. Can I use 4 SFP ports and stack of two switches at the same time.
2. Is it possible to use for stacking ports other than 24, 48?
3. What is maximum possible number of ports to use for stacking (can I get more than 1Gb thruput).
We 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.
Am 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?
I currently have two SGE2010's with a 4-port LAG configured between them. I'm looking to add another two SGE2010's and I want to add redundancy at the same time. The switches are currently in standalone mode. I don't have fiber connectors and was planning on just using copper for the uplinks.
My questions are:
- Is it possible to use stack mode in conjunction with 4-port LAG groups to create redundant 4-port links between all of the switches? The documentation says that ports 24&48 are reserved for stacking - does that mean I can't specify a LAG instead?
- If 4-port LAGs aren't possible, does that mean that these switches max out at 1Gpbs uplinks if you use stack mode?
We 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?

I 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?

We 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?
Currently, 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.

View 13 Replies View RelatedWe are experiencing bridge storms and network slow downs and we believe we have traced the issue down to users plugging a cat 5/6 cable between 2 ports on the wall both wired back to a SGE2010 switch.
So we did a test - we plugged a single short cat 6 cable between 2 ports on a SGE2010, our access switch. Suprisingly, even with STP enabled, the switch DID NOT block one of the ports and in a few minutes the ENTIRE NETWORK was down, as CDP, STP, and ARP traffic became a multi-gigabit storm throughout the network.
Why on earth does this switch not block a port that is obviosly looped?
Every other cisco switch since I started on 1900XL's did this in 1999.
Id like to set up our AP to push our different vlans depending on which ESSID you connect to.
A few things I am unclear on. The switch port on the SGE needs to be in trunk mode I assume.
Do I marry the Management Vlan ID on the AP to the PVID on the SGE port ? Or is the PVID the untagged vlan ID ?
I set the switches port to trunk mode, it's PVID to 10 and set the management vlan ID on the AP to 10 and I get TTL Exceeded in Route when I try to ping.
I've recently installed an SGE2010 switch, which I have set to 'Layer 3' mode.
I have created 2 VLANs using 192.168.10.x and 192.168.20.x (using .50 for the VLAN IP address in each case) - however, I need to be able to allow certain traffic between the VLANs.Alternatively, to get things started - I'm assuming I need to set up ACLs to allow access between VLANs - how would I configure the switch to allow all traffic from one VLAN to the other?
I have been told there is a limit (8) on the number of source ports that can be mirrored to a given destination port. I can find no specifications or other documentation to corroborate this claim. Any factual data to confirm or refute this claim?
