Cisco Switches :: SG500x Stack And Connect To A NAS Device At 10G
Oct 11, 2012
I purchased 2 SG500x switches that I will stack and connect to a NAS device at 10G. I need to purchase transceivers. The documentation has me confused. I just want to make sure that I can use SFP-10G-SR to stack and as the interface to the NAS. S1/S2 for stacking and XG1/XG2 to connect to the NAS all at 10G.
I just deployed two stacked SG500X switches. I noticed these messages in the log (see below). Despite these messages everything appears to be functioning.

before I open a TAC case: How does Cisco Prime NCS handle the device licenses for stack of 3750 switches? Just one device license for the stack or a license for every physical switch in the stack? I can't find a answer on the Cisco website, but maybe one of you knows it from a deployment you have done..
Trying to connect SG500X-24 switches to a new installation of MOE (four sites)provided by Century Link. I have tagged the uplink port with the MOE vlan, but traffic does not want to pass through.
I need to confirm how many queues actually supports the switch SG500X?. In SG500X_data_sheet.pdf document (pg. 8) say they have 4 hardware queues (8 future) !
We have a VOIP system with 1 physical NIC attached to our SG500X. It has a virtual MAC address along with the physical MAC address. It has 2 IP addresses tied to it.
I can ping the physical IP address, but can only ping the virtual address from the same vlan as the virtual nic. However, if I clear the arp table, a few pings will go through until they all time out again. This is causing problems on my phone system, and I need to establish this communication. I have tried putting in static MAC and ARP entries, but that does not work.
i was checking the datasheet of 500X series and got confused regarding the 10GE uplinks. how many 10GE ports can be used for uplink and which transceiver should be used for 10GE copper uplink? for example, SG500x-24 switch has 24GE ports and 4x10GE uplinks. can i use the 4x10GE ports for uplinks or only 2 ports are for uplink and the rest for stacking?

We currently have the XG1 through XG4 ports on our SG500X switch setup in a LAG with the Cisco 10G-FiberOptics. Everything is working fine,however in the web UI under Port Management->Port Settings the "Port Speed" is listed as Unknown. All other ports report the speed correctly. We have 2 SG500X switches configured this way and both are reporting the same Uknown speed.

I am installing a network that has two SG500X-24 switches as core and several SG300-52 switches as access switches. I've seen in the SG500X-24 datasheet that there is a True Stacking feature. But in the data sheet there are not a lot of details about it. My doubt is the following. If I configure the two SG500X-24 switches as a single switch through stacking them, can I connect one SG300-52 switch to these two SG500X-24 switches through two cables (both configured as a LAG in the SG300-52 and in the SG500X-24 stack, one cable per SG500X-24), the the first cable connected to the first SG500X-24 switch and the second cable connected to the second SG500X-24 switch and keep both connections active?
We have a site with a number of SG500X switches who are about to have a new server installed.
The server is a Dell ESXi host with a dual port 10Gb NIC supporting SFP+.
I know the primary purpose of the 10Gb ports on the SG500X is for stacking etc. but the switch does come with four 10Gb ports.
Why I wouldn't be able to utilize a 10Gb port as a copper connection to the 10Gb NIC on the server? Anyone out there with a SG500X connected directly to a server at 10Gb?
I have two 3750 layer3 switches and I need to connect them via stack cable.so if I connect them with the stack they will be act as an one switch, but for the configuration if I create a VLANs on the master switch (applied all the configuration on the master one) this configuration will be transfered to the slave one or I have to repeat the configuration that I did on the master.
I have a point to point 100mb line connecting SG500x switches at 2 locations, with these ports in a vlan together. I use layer 3 on the SG500x's to route between the two sites. I also have RIP protocol enabled to allow for automatic failover if the point to point fails (this works well).
I upgraded the ios to 1.30.59, and the connection now runs at a fraction of the speed. I have hard-coded the ports to run at 100mb full duplex, but I still only get around 12mb of throughput between the switches. I used to get about 90mb before. The provider also hard-coded the circuit to 100mb full duplex. The provider has checked the circuit remotely, and everything looks fine. I tested with a laptop at each side, and did get almost 70mb throughput. I would think this indicates some type of setting mismatch, but i cannot find anything.
I am using a backup vpn for now as some things look flaky as well (on vpn, I can use the web interface to access the SG500x on the opposite side, but on the point to point I cannot - I can ping the device though).
I have seen some references on here to shutting off STP on these 2 ports.
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).
I would like to find out if the Cisco SFE2000p supports Link-Aggregation in a stack. For instance Unit 1 interface 1 and Unit 2 interface 1 in the same LAG?
Can I create lag betwen stack unit to increase speed between units ?? stack connection is only 1Gbit on ports 24/48 if posible lag link must be in trunk mode ?
I have 3750 stack with 4 switches.I am trying to make change some port to new VLAN, but switch 2 & 3 new change never works, the ports stick with old VLAN. Other two switches works as I expected on new changed VLAN.Tried to reboot, no progress.

I have 3 SLM248G4S switches in a stack (SW1, SW2, and SW3), and want to pull one out and configure it as a stand alone.
If I just disconnect the stacking ports from SW3 and reconnect the bottom stack port from SW2 to the top one of SW1, the two switches continue to function together fine, but SW3 still seems to think it's part of the stack (still shows #3 on the LED screen) and doesn't work at all. I cannot even telnet into SW3.
I have to setup my first flex stack and wanted to make sure I do it right. I have the physical aspect of the stack down. From what I gathered I have to setup the master switch as the highest priority and then provision the other two switches. But I have configs on the other two switches, do I have to delete them? And do I have to setup individual ips for the two slave switches, because from what I saw the master switch is the only one with an ip address? The master switch is a poe 2960S-48LPS and the two other switches are 2960G-48TD
I am running LMS 4.1 and have an issue with Inventory: I have a stack of four 3750 switches, but only two of them are showing up in CiscoView. If I right-click - Topology - Device Report ; I see all four switches. The switches are standard 3750 switches and should be included in the Device Packages for CiscoView
Also if I go Reports - Detailed Device ; I see the same two devices show up under Module Information. However when I go to Reports - Device Attributes ; I see all four devices correctly displayed.
I have tried and deleted and added the stack in CiscoPrime, but with same result.
I have 2 switches c3750 which I want to install in stack to replace two Nortel switch that I have in production.
When connecting my new stack of cisco switches to a cisco router c3750 to 2600, they begin to restart by itself. I mean, There is a cisco router 2600. which I want to connect to the stack of switches. The problem is that when the switches connect to the router it begins to restart.
If you need to see the running config of the cisco Switches or the 2600 router.
Recently, we had a 3750X stack of 9 switches reload with no information as to why. Our syslog server received no spurious errors regarding the cause nor did the location lose power. The UPS to which it is attached logged no glitches relating to power. Other cisco devices (router, other switches not in the stack) did not reload. No one was in the MDF during this time. We self insure these line of switches so a TAC case is not an option at this time. Any forensic tools that I could try in an attempt to narrow down the cause.
Im trying to recover the password from my stacked switchs(doing procedure on master switch),im following a guide i have read in this forum("SRW248G4 V1.1 unable to reset password"), at console terminal have chosen "password Recovery" it prompts the "current password will be ignored" and then i hit "Escape" the switch start loading de configuration, at this point i attempt to login from telnet or http but the login fails. Here is the password/username combo im using (admin/blank ; admin/admin). Is it possible to restore admin password or should i just hardware reset the switchs?
Symptoms: The switch hangs - after a hard reboot and after two hours switch No. 2 flew out from the stack. After the reboot, everything returned to normal and now when a few days passed switch works without problems. Devices: WS-C3750X-24T-S
I'm using a stack of four SGE2000P switches for a PoE video camera system. I've got the cameras in a VLAN and everything's working fine.
I'm wondering, though, is there a way to find out what data rate the stack interfaces are working at (since it's going over cable infrastructure we put in ourselves), and also what percentage of that bandwidth is being used? I don't see anyway to get to those interfaces from the main page, and I wasn't able to find a way to do any sort of percentage thing even on a regular interface.
I have a 3845 enabled for CDP connected to a stack of 3750 switches. From the router, i dont see any CDP neighbors. From the switch, i can see the router as neighbor. Why isn't the switch showing as a neighbor from the router side? [code]
