Cisco Switching/Routing :: Running-configuration On Stacked Switches (C2960S)?
Apr 2, 2012
My 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.

How 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.

I 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.

I was looking at WS-C2960S-48FPS-L (740 Watts) and WS-C2960S-48LPS-L (340 Watts) models today, I'm not sure that I understand it right,
Does WS-C2960S-48FPS-L model support all 48 ports POE+ (30Watts)? Does that mean each port will get 30 Watts on this switch?
Does model WS-C2960S-48LPS-L support 24 ports with POE and 24 ports with POE+?.

find out which types of fiber optic that i can connect to three types of switches. the setup that i have that there are:8 access switches (WS-C2960S-24TS-S), in each one there is two SFP connections.2 aggregate switches WS-C3750X-24T-S, in each one there is four SFP connections.and one core switches that has SFP card WS-X4624-SFP-E? Note that the fiber optic that we have coming from filed are multimode.

Our network administrator restricts all our new 1Gb switches to only 100Mb, to which he claims it will increase overall performance. Preventing devices from bottlenecking the network. (that is, only restricting the main switch ports, not the uplinks)For example we have a new building with 2x WS-C2960S-48TS-L connected together with FlexJack and then a 1Gb Fiber connection back to our core switch.
This building is on it's own subnet and there is little broadcast traffic. I don't see the point other than it hinders the potential speed we could use. Labs are set up in this building and 1Gb is MUCH faster when it comes to imaging and software deployment.

I have 30 switched in my corporate network it’s all up and running all switches running by default configuration and connected to WS-C4506 core switch our dhcp server pooling 192.168.100.1/27 network. Now we need to configure new Vlan for finance department this department has more than 200 users. If my server distributes 192.168.200.0 range ip can vlan2 automatically assign ip 200.0 addresses to finance department.All switches running default config no ip address assigned.

We have a bunch of switches that are running fine but the running-config file is missing and we can't save the config to the tftp server. IOS is c3550-ipbasek9-mz.122-37.SE1. I've got lots of these switches running the same code that are just fine.

I have a new 6513 with 2 sup32's with IOS. This chassis will replace a working 6513 with 2 sup2's with CatOS.I would like to convert my CatOS running configs to IOS, and I know there used to be a tool for this.
I have searched around and found many broken links to an old Cisco tool to convert my former configs, is there any way to get this tool today? I have tried over 20 links and not been able to find a working one yet.

I've upgraded a 6509 switches wich are running in VSS, from IOS 12.2 (33)SHI1 to 12.2 (33)SHI5. After that I'm facing the folowing log messages periodically. [code] I know that this is a diagnostic result from TestUnusedPortLoopback feature. But this interface is disabled (shutdown).

Looking for feedback from other organizations that have large 3750 stacks. I've got one stack of (8) 3750's composed of (6) 3750G's and (2) plain 3750's. This particular stack is usually unresponsive to SNMP queries and often fails to write config when we make changes. After a couple tries it will finally go. Part of my probably here is likely the plain 3750's that always boot faster and come up as the master. I should manually set the master to one of the G's. What I'm wondering is who else has 7-9 3750's stacked and are they performing well for SNMP, telnet, etc? I've got another newer stack of 7 3750E's that I need to add one more switch to. Need to decide if I want extended downtime to break the stack up or just add the 3750X to make member 8 and hope it performs well. I have 50+ 3750 stacks working great on our campus.

We are implementing NAC in our environment and unfortunately still some of our obsolete 6500 switches are running CATOS, the current (cat6000-sup2cvk9.8-6-4.bin) image does not support some of the commands related to NAC implementation. Therefore, I would like to urge you to provide me the 8.7 image which supports all the NAC related commands and will be easier to finish the long pending assignment.
We are in process of replacing the obselete hardware but that will take time.
So, 8.7 K9 CATOS image required.

Would it be possible to change output style of "sh running-config" in SF-300 switches to Cisco IOS-like format (eg.: options related to the specific interface put together, add tabs) in the next release?

Im trying to stack 2 3750E-24PD-S and 2 3750X-12S-S. The 2 3750E finds eachother and stacks with one master as they should. The problem is that and the 3750X does the exact same thing instead of joining the 3750E stack.Both runs the same IOS (c3750e-ipbasek9-mz.122-58.SE2).The stackingcables are connected like following atm (I tried booting up the switches one at a time and all at once, no difference in the result).

If we have 3 stacked 3750s# running Layer 3. Do we need license for every switch? or is it one license for the 3 switches? Also is the license associated with the MAC address of a specific switch? What i# am trying to know also, is if we have to install one license and it is associated# with one MAC and this switch failed.. will the Layer 3 be broken?

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.

I 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.

I have a customer who just bought a pair of N5K and wanted to replace his current HP E3800 as Core. He wants to use the 4 x stacked HP E3800 connect back to the N5K. Will I be able to utilize VPC through a bundled 2 or 4 x 10G (40G) connection (10 or 20G on 1 switch, and 10 or 20G on another switch) from the stacked HP E3800s to the N5548s? I know you can do that with Cisco 3750s.

We have two 3750-x stacked switches with IP base license. We need to upgrade them to IP services license. I read some where that it is possible to install IP serivces license to only management switch and no need to purchase/install same license to other switches on the stack. But, I could not find/recall where I read it and as far as I know it was not official cisco documentation.

I was wondering what general steps might be taken in order to "replace two(2) 3750 (stacked) with one (1) 3750X - Server Access". General steps and what I might have to do configuration wise. I know i'm copy pasting the existing configs into the new switch, but are there any caveats?

I am looking for a reasonable switch but it has do do inter-VLAN Routing. I know I could go with a 3560/3750 with IP Services but I am also thinking the 2960S with IP Base IOS might do?
I have looked up the IP Base IOS and it does list IP Routing but how to actually configure inter-VLAN Routing on a 2960S with IP Base?

I have a pair of Cisco Nexus 7000 switches in a VPC configuration with several Nexus 5000 switches attached. The config has about 50 or so VLANs each with a /24 subnet address assigned. These SVIs include HSRP etc and are all a member of the same VRF. Unfortunatelu I am not able to advise/confirm if the issue is on the last vlans and svis configured as I am not aware of the history/chronology of the configurations applied.
The issue I have is that one of the Nexus 7000s seems to take some time providing output or even freezing until I issue a Ctrl+C when issuing simple commands such as "show ip arp vlan 123 vrf abc123" or "show mac address-table dynamic vlan 1234". This seems to affect only some but not all vlans or all SVIs in the VRF. This behaviour is the same whether accessing the cli via a console, SSH and/or telnet session.A check of CPU and mem reveals little utilisation to cause any concern and will begin a bug toolkit hunt for version 6.01.

My question is regarding VSS configuration on Cisco 6513 switches. My understanding is that the hardware and software configuration on the devices must be exactly the same for the VSS to function correctly. Do the Bootstrap versions also have to be identical?
The production switch is running Bootstrap Version 12.2(17r)SX5, while the new switch is running Bootstrap Version 12.2(17r)SX7.

We have two switches WS-C2960S-24TS-L running in stack with running IOS c2960s-universalk9-mz.122-55.SE3.We have connected two checkpoint devices on Gi1/0/24 and Gi2/0/24 with a simple configuration:
interface range GigabitEthernet1/0/24, gi2/0/24
switchport access vlan x
switchport mode access
spanning-tree portfast
On the devices log we get the following message:
%SW_MATM-4-MACFLAP_NOTIF: Host 0000.0000.fe21 in vlan x is flapping between port Gi2/0/24 and port Gi1/0/24
The mac-address 0000.0000.fe21 is not found on any checkpoint interface. "Show mac-address int gi1/0/24 or gi2/0/24" does not show the correct mac-address of the checkpoint interface connected to the port, but instead shows 0000.0000.fe21.Is there a bug in the IOS, something wrong with the switch config or does it have something to do with the checkpoint config?
