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.

Nov 15, 2011I have a 4 member stack of 3750's. We would like to take advantage of wccp and we understand that we will need to upgrade our switch licensing from IPBase to IPServices. My question is do we need to pay for a license for each member in the stack or does one IPServices license upgrade cover the whole stack?

Cisco Switches :: Dual Stacked Series 500 Switch?
May 10, 2012I am about to buy 2x Series 500 switches but before that I have a design to be sure :I want to create a redondant network so it is the reason why I want to stack 2x Series 500 switches.Each server on my network (ESX and Windows 2008) are connected with two NIC (one port on the first switch , one port on the second switch), with trunk mode + etherchannel for LACP.
First question : I saw that the limitation is up to 8 etherchanel groups, can I have a mix of multiple servers on the same etherchannel group or should I create one etherchanel group for one server with only the two NIC inside?
Second question:I want to use the series 500 to do intervlan routing and want to be sure that if the the ports are in trunk mode with some vlan set on the card itself that the default gateway for the vlan will be propagated on the two switches (in stack mode) and will not cause any issues when both switchs works fine and if one switch crashes?
Cisco Switching/Routing :: How Many Switches Can Be Stacked With WS-C2960S-48FPD-L At A Max
May 28, 2012How many Switches can be stacked with WS-C2960S-48FPD-L at a max..
As per my Knowledge it is 4 and as below..
Switch 1 to Switch 2
Switch 2 to Switch 3
Switch 3 to Switch 4
Switch 4 to Switch 1
If yes then, is it mandatory to do the "Switch 4 to Switch 1" stack. why am I asking this is because this stack requires a long cable and the cable which comes with the Switch is only 0.5M.
Cisco Switching/Routing :: Running-configuration On Stacked Switches (C2960S)?
Apr 2, 2012My company is beginning to have a lot of sites were we are stacking 3 to 4 C2960S-48 switche.This is making "show running-config" very very long because of the 4 x 48 interfaces.I can’t find a CLI command that show me the running-config of a ranges of interfaces. If I for example would like to see running-config for switch 3 (interfaces 3/0/1-52)The Show Running-config will show all the interfaces (for the two first swtiche = 104 interfaces), which take a time before I reach to switch 3.I miss a CLI command like: show Running-config switch 3, or module 3, or show running-config interface range x/x/x-x ?I’m well aware of the CLI command show running-config interface x/x/x, but this will only show me one interface.

Nov 17, 2011We have been set the task of securing a small managed office system which is currently set up with a standard switch allowing each of the offices (containing different companies) to see each other, and in some cases, access each others documents across the network.
Obviously this is a far from adequate set up and our aim is to isolate each office using VLAN's but share a common internet connection provided by the managed offices. We have two Cisco SGE2000-G5 layer 3 switches but we are new to Cisco equipment and VLAN's so we are not quite sure on how to implement this. DHCP would need to be provided by a Router, there is no Server. We are open to suggestions on the Router as we have yet to purchase one.
Cisco Switching/Routing :: 3750x Stacked Switches With Latest Firmware
Feb 25, 2013I have two 3750x stacked switches , both with the latest firmware on them. I enter the configuration onto one switch and it obviously copies over onto the other switch. Although in the configuration I have both a console username and password and an enable password, when I try to log onto the initial switch that I entered the configuration on, I am prompted for a username and password, which works fine, but when I try to enter enable mode i get an error stating that no password has been set. However when logging onto the other switch I am not prompted for a username or password but when I try to enter enable mode I am prompted for a password and can access it with no problems.

Feb 18, 2013We're running two 5508 WLCs running 7.0.235.3 pushing out 7 WLANs. They are both live. Each WLC is connected to the same stack of 3750G running 12.2(44)SE6 via Etherchannels.I'm getting tons of MAC flapping errors similar to this:9373213: Feb 19 10:53:54.564 CST: %SW_MATM-4-MACFLAP_NOTIF: Host 843a.4b3c.4cec in vlan 752 is flapping between port Po12 and port Po11Each portchannel consists of ports on each of the two switches in the 3750 stack. Only VLAN 752 shows the flapping activity. LAG is enabled on the each of the WLCs. The portchannel and interface configs are identical, minus the channel-group command of course.Maybe completely unrelated....looking at CDP neighbors from the switch is incorrect:

Cisco Switching/Routing :: 3750 E And X Could Not Be Stacked

View 1 Replies View RelatedCisco Switching/Routing :: Mac Flap Errors On Stacked 3750G
Feb 27, 2013I currently have a stack of 3750G switches with a cross stack etherchannel connected to a 3750E stack in the distribution layer.The 3750G stack is running 15.0-2SE IP Base. I began noticing the Mac flap issue when I was Re-enabling dot1x on the switchports. As first I thought dot1x maybe have contributed to this so I removed it from the stack temporarily.I am still seeing Mac flap logs usually when a machine reboots or re-connects back to the network. These are all wired desktops.I started looking at the etherchannel configuration which is using LACP. The 3750E stack looks fine with all ports in mode active. On the problematic 3750G stack I noticed 3 of the ports in the etherchannel set to mode active and 1 port set to mode passive. The port shows as bundled but I can't imagine this is ok.The only other difference on this one port is there is no mls qos commands like on the other 3 interfaces in the port channel.I mainly need to know what the Mac flapping is about. Whether it is a bug or related to the current etherchannel configuration.

Cisco :: 5508 / 3750 - Connection Between Switches Using SFP Cable
Nov 14, 2011I have to realize a connection between an 5508 WLC and 3750 switch using one SFP cable. I found on Cisco documentation some reference about two different SFP cables. The first one is CAB-SFP-50CM, but this is used to interconnect two 3560 switches. The second is SFP-H10GB-CU1M. This one has SFP+ transceivers on both ends which I don’t know if are compatible with the standard SFP ports that can be found both on WLC and switch.
My question is if I can use one of these cables in order to connect my devices, or if you know other one piece SFP cables.

Cisco Wireless :: 5508 Students Unable To Join Wireless With Personal Laptops
May 1, 2012I have a WLC 5508, AIR-LAP1142N APs and a SSID for students to connect to who bring their own device. I am still testing this and it has not been rolled out but I am running into some serious issues with joining the network. I am authenticating them through a RADIUS server (2008 R2). Problem: many of them cannot connect because they are lacking the certificate.
1. What is a good setup for authentication in a BYOD environment
2. If my setup is good what can I do to allow kids to use their computers on the wireless either without the certificate (which I know is unlikely) or what do I need to have them do to connect. I am hoping it does not involve hard wiring and getting the certificate from the server.
