I have 5 VLAN's setup in the sge2010. I have one port (uplink for the network) that I want everyone to see. But have separate VLAN's for different departments as to keep them all separate. Everytime i try and Untag that uplink port, i lose my untag in the original VLAN it was tagged in, and it changes to excluded.
View 13 RepliesI 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 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.
Our environment consits of 4 cisco SGE2010 switches (stacked). I have implemented STP BPDUGUARD and Portfast on all client ports (suspected a loop). And our uplink to the Server DMZ recieves almost all of it's BPDU packets back(is that normal?) The issues lies where we have random ports dropping out - across all stacks for seconds at a time. We get errors/warning such as,Pinging between the DMZ network appears to be fine. Pinging from the client/switch network show packets being dropped quite frequently.All devices are on VLAN1 (I've have researched this and this could be the cause of the issue)

In order to prevent students from playing certain online videogames some ports are blocked for all machines on the network, but they can be manually untagged (ie for competitive play). The problem occurred when we tried to untag the ports to allow online games on this machine. After the allowed ports were modified, the machine refused to assign an IP adress to itself - no matter how many times we try to renew the DHCP Lease. Restoring the previous set of allowed ports fixes the problem, but doesn't allow for online play.

I have two questions for a Cisco 2960 (WS-C2960-24TC-L)
1. I am working to setup a few Cisco 2960 switches for HP iLO access to our servers. We are going to segregate the iLO network (VLAN 40) from the data network (VLAN 10) by using a different VLAN. All of the HP servers will be configured with static addresses. My question is, how do I set all the ports to VLAN 40 so that untagged devices will automatically go onto VLAN 40? I don't want to have to configure the VLAN on each iLO port on the server. I tried to set the port to: "switchport trunk native vlan 40", but that didn't work.
2. Also, how do you access the web GUI for these switches? I get a login box, but putting in the enable password doesn't work. I have the following commands in the config: [code]
I 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 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?
I am working on two SGE 2010 stacked and in routing mode. Everything work fine but before finishing the job, I wanted to lockdown all the network device so they would not be accessible from some subnets. Problem is, I cannot bind my ACLs to any interface. I get "Cannot apply because lack of HW resources." I am running firmware 3.0.0.18, and 3.0.1 release notes don't address that issue. TCAM utilization is at 3% Routing resources shows host: 200, routes:60, ip interfaces: 50 I have tried from the cli and get the same message.

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?

what is the process of updating firmware on a SGE2010.
I would usually use TFTP - but, I can't see the TFTP command on these SGE2010's
I need to move the client machines off of the 3750 (and their DHCP dependency on it) to the SGE2010 and absolutely route their internet traffic out through the outside interface on the 5505. They must also be able to communicate back into the internal environment in order to communicate with the production servers.
The clients currently use .254 addressing through a dumb dell switch to the 3750 but I am trying to migrate them over slowly to the .253. I know that the 2010 will not do DHCP, so I am putting a DHCP server on that switch right now. The 5505 won't let me add an additional nameif statement onto one of the other eth0/x interfaces and I'm not sure if that has anything to do with it's capabilities to act as a DHCP server (it's not an option in the ASDM) or it's ability to serve as the internet gateway for the 2010 clients. (Side notes: The 5505 has a base license and is currently also connecting 1 site to site VPN. As is the 5520, so all of it's interfaces are used as well).
I statically assigned a moved client with a .253 address and plugged it into the 2010. I have tried giving the 2010 both a .4 address and a .253 address but neither will allow me to ping any of the addresses on the 5505. The 2010 shows automatic routes to the two subnets and I set it's default route to 253.1. The link between the 2010 and the 3750 works - clients receive a .254 address from the 3750 and can get out to the internet via the 5505 and reach the production servers as well.
Why won't the 2010 see the 5505 as a gateway and allow clients to get to the internet and also traverse the 3750 when they need access to the production network?
The reason why I dont' just connect the two swtiches and call it a day is because I also need the production servers to ALWAYS go out/receive web requests via the 5520 outbound/outside interface. I'm having such a hard time wrapping my head around why i can't get my clients moved over to the new switch, I haven't even grasped how I'm going to do that yet.
I have currently a Dell powerconnect 6248 switch combined with a netgear UTM router. I have a basic understanding on how things should work but I don't have the knowledge to apply it as I'm new to setting up vlan and the person before me did the basic configuration like this:
defined 5 VLAN in the netgear router
defined the same 5 VLAN in the dell 6248
connected the dell switch to the netgear router via a trunk port.
Right now all the inter vlan traffic pass thru the netgear router as the dell switch as a trunk port connected to the netgear box who then give dhcp and set himself as the default inter vlan route. I would like to stop that since I would like the cisco switch to handle all the vlan routing for both switch and those switch to send their dhcp request to my win2k8 server.
I did set the sge2010 in layer 3 mode from the small business telnet interface. I then setup the same 5 vlan in the cisco switch.
If I understand this well I need to define an IP address for each vlan interface on the cisco switch for it to be able to route things, I have set them all as x.x.x.3 (x.x1.3 vlan 1, x.x.2.3 vlan2, etc) Then I need both swtich to forward all dhcp request to my dhcp box wich is in vlan 2. My DHCP server will have 5 range of IP address to hand out. my server are connected directly to the dell switch on vlan 2. I have set up a port in the dell switch in trunk mode and did the same thing in the cisco switch and connected them togheter to send all vlan packet. The current setup doesn't work so I need to finalize that setup so that everything works.
answer regarding stacking the SGE2010 switches versus link aggregation if greater than 1 Gb connectivity is required between individual switches? 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?

What i have: An SGE 2010 48 port switch, firmware 3.0.0.17 Firmware upgrade: In order to ensure im not having problems due to old firmware, i tried to upgrade using ros_ls1_bp_ge_bx-3020.ros in order to move to 3.0.2, when uploading the file via TFTP, the upload completes and thats it, nothing happens.Restarting the device: As part of the upgrade process, i thought i might of had to reboot, so i rebooted, and found that all my settings were wiped clean, as if a factory reset had been performed.... and add further to pain, the backup of settings that i had taken do not seem to want to re-apply.NAP support: So i have tested my NPS (radius) server with NTRadping.exe and all is good, however i cannot get the SGE2010 to talk to it.... the authenticator state in the web interface is always listed as initialising.... im not sure if this is a simple incompatibility (hence the attempt at a firmware upgrade), a tag that needs to be set on the radius side or a switch misconfig.
1) how on earth do you upgrade the firmware?
2) why are none of my settings being saved when the device reboots ?
I have several SGE2010P switches connected in a stack. They are working fine as a stack.
Question is - what traffic, besides stack control, is carried over the stacking links?
All unused ports are VLAN 1U. Ports in use belong to VLANs 100, 101, and 105.Since I cannot configure or see the stacking ports, I am unclear if any non-default VLAN traffic passes over those links between switches?
