Cisco :: 4507 - Lost Ability To Change Vlan With CNA After Redundant SUP Upgrade
Jul 29, 2012
We recently had redundant sup cards installed in 2 of our 4507 units after the upgrade I can no longer change Vlan's with the CNA program.I upgrade to the newest version of CNA but that didnt work.
I can still get Vlan information from my 4503's and 4506's with no problem. I figure it is an issue with CNA selecting the sup card to get it's information from?
We are in the middle of some major user moves and changes so I have had 2 of my guys working to move printers on to their own Vlan and some other changes neither is well versed in command line so I set them up with CNA for simple Vlan changes. Now with this out I have to go in and make the changes myself and keeping up with that and my other duties is getting tough.

I have been using a shared network (5 computers) for 2 years and all of a sudden I cannot access it anymore. It should be connecting to the host computer, CHRIS-PC, but I get an error message that Windows cannot access it. All 4 other computers can access the network fine. I did recently clear some malware off my computer with SpyBot, would that have changed any settings?
Network discovery is on
Netbios is enabled
Windows firewall is disabled
AVG firewall is disabled

I picked up this RV180 router because it has one of the fastest thru speeds of all the routers tested that I viewed on smallnetbuilder. That and it has the cisco name. I grew tired of purchasing wireless home routers every year after they fail. So far the thing is nice with one exception.
I have one device that is essential on my network called an airave. It is a small device similar to a wireless access point that works on springs voice network. The thing essentially makes a small cell tower inside your house and connects to the sprint network through an Ipsec vpn. I have not ability to change ipsec settings on the device on my end. The device works fine connected to the cable modem or to the old slow dlink. When I first connect the thing it works fine for about 5-10 minutes on the cisco. Then the thing loses connection and I lose my cell phone service. Just to test any port conflicts I made this the the DMZ with no luck.
I have also tried a firmware upgrade. I have not messed with any of the firewall settings or port forwarding since DMZ should in theory fix that. I have assigned the thing a fixed IP address but that does not seem to make a difference. It did not on my old router and is mostly just for my sanity and to facilitate the DMZ.

I attempted a firmware upgrade on my RV042. After an hour, the upgrade was still in progress. I now cannot login into the router using my user name and password (nor the old admin/admin). The router is functioning, but I fear it will eventually fail. How can I recover ability to log in? The Firmward Recovery program doesn't seem to be appropriate for this situation.

We are running ACE 20 modules in highly available active / standby (all active contexts on one module) mode. Currently they are on A2 (2.4) version. We are going to upgrade them to A2 (3.6a). The question is that how ling can we run them in two different SW levels? In otherwords can we have few days between upgrading both modules?

we have 2 Supervisor IV modules in our 4507, i want to upgrade the IOS as its still on 12.2 and i am going to upgrade it to the latest.
my first question is, if i update the IOS on the bootflash will it replicate to the secondarybootflash?
secondly, can i force a reboot of the secondary supervisor, then the primary after the secondary is up? i'm just trying to minimise downtime and get a plan going.
is there a difference in 12 vs 15 that would impact my current config that i should be aware of?

I have a requirement to monitor all traffic going from the internal LAN to the cloud. The LAN is a layer 2 VLAN which spans multiple Cisco 4507 switched and other smaller switches.
The VLAN has an IP address which the hosts use as the default gateway.
The exit port is on a Cisco 3600X switch connecrted to 4507 #1 via a 10G fiber link. 4507 #1 connects the rest of the LAN. Those switches interconnect via 10G fiber and 1G copper links.
Currently the monitor host is connected to a 1G copper port, configured as a monitor port, on one of the backside 4507s The switch manager says he has the switches configured so that I can see all traffic on the VLAN.

We have a number of 4507s. Most are managed via VLAN 1 address. All have multiple VLANS for traffic control. When I do a show ARP or show IP ARP the command only shows VLAN 1 info. No entries for any of the other VLANS on the switch.

We are trying to setup a new configuration with 2960S as access switchs and a 4507 as a core switch.I want to protect the management IP VLAN of the swich using vrf on the 4507 so we :
SHUT VLAN 1 on every switch (2960 + 4507)
CREATE A NEW VLAN 289 (management vlan) -> IP network : 10.32.126.192/26
L3 VLAN on every switch
VLAN 289 in the VRF XXX on the 4507
create tunk between the switch and the 4507 :
switch mode trunk allowed vlan 200-230
sw trunk native vlan 289
so with this configuration on the 2960 the vlan 289 is UP/DOWN and UP/UP on the 4507 I can access to the 4507 using the IP in the VLAN 289 but i cannot access to the 2960 behind the 4507 CDP connectivity is ok?

I faced one problem in our core switch 4507 R . Active sup lost connection and standby came active. We got lot of errors/alerts on console shown below. [Code] Also when I reloaded the switch with reload command only both sups got reloaded but I want to reload all the modules but reload command do not gives any options for that.

Just implemented a couple of replacement DNS servers so decided to test by disabling existing Server DNS services only (10.0.0.21)Two problems arose from this, first was I lost access via the ASDM, second was remote access failed. The Cisco VPN client worked but RDP could not find the remote access Server.I've replaced the DNS settings everywhere I could think on on the ASA so decided to check the running config and noted these lines that refer to old DNS.Would this suggest the cause for the RDP, although looking at the various group policy areas on the ASA I could not locate any reference to 10.0.0.21/22, am I missing something?

Upgraded our WLC 4404 from 6 to 7 so we could upgrade some WAPs to 3500i. After upgrading all 8- 1120 and 1240s connectivity were lost.
We reverted back to OS 6 and all came back to Controller
WLC Software version = 6.0.199.4
WLC Emergnecy Image Version = 7.0.235
[Code].....
Our vendor states this should be a compatible mix and they are also checking as to why it is not working as planned.

I have a Dell PowerConnect 5448 and i had a separate VLAN setup for my iSCSI traffic. Now yesterday I was going to add a few more ports to this VLAN but when i went into the switch the VLAN was gone. I know it was configured and saved because a few weeks ago when I set it up, I went into the switch several times to adjust stuff. For some reason when it lost power it may have reverted back to default settings.

I have two Cisco SG300-20 switches. Both of them are configured in L3 mode. They have several VLAN's configured.
When I reboot my switches some VLAN membership settings are lost! I have already saved the settings over and over before rebooting, and even tried to save it to the backup memory and so on. Say for example I have changed port 9 to 14 from VLAN 101 to VLAN 105. I save the configuration, reboot the switch. And then the changes are lost. This is a big problem, because servers and my iSCSI network loose connectivity. They already have the latest firmware. This issue was there three firmwares before.
This issue pop-ups when I have a power loss, or I need to reboot/shutdown them manually. It may be off-topic but I also have the feeling that the performance of the switches goes down during uptime. A reboot solves the performance issue. I don't have a performance benchmark, but I can notice it on the performance transfer rate between clients and servers.

Lost my access points to controller. Not sure if it was related to upgrade from 7.1 to 7.2, or something else.
The console log on APs shows;

i bought a WRT160N router
I connected the Router to the modem, and all the wired connected PCs were working perfectly.But then, i went to the setup page to configure the Wireless settings, and as soon I changed the SSID name, the connection internet connection droppedThe only way i had to fix this was by making a Hard Reset.after that, I also tryed changing values and settings from all the configuration tabs, and the wired connection was working properly, but as soon i changed any value from the Wireless tab, the internet connection dropped (even, in the diagnostics section, i could not do a ping to google. It says unknown host).

We have a switch gc2960. It has ports configured on vlan 27 and vlan 29.It is connected to switch ch3550. It has presence of vlan 27 vlan 29 and also vlan 18 and several other vlans.Our internet firewall is connected to ch3550. It is a fortinet product, so this is not indicated on the diagram.
When the two switches were connected on vlan 29 access ports, pc's on vlan 29 on gc2960 worked as expected. vlan 27 clients of course did not work.When we switched the connecting ports to trunk ports, some weird stuff happened. Clients on gc2960 on vlan 29 could ping and resolve dns, but not browse the intenet. The same was true for clients on gc2960 vlan 27. We verified that packets from the web were coming in through the firewall. What we were thinking, is that they somehow were not being tagged to vlan 29 even though we were trunking.
When we set native vlan 29 on the trunk, then clients on gc2960 vlan 29 operated as expected. However, clients on gc2960 vlan 27 are still having this problem, we can ping and resolve dns but not browse.Consider the other switch ch2960-jstreet which has presence of vlan 18 and vlan 27. It is also connected on trunk to ch3550. We are not using native vlan on this trunk, and traffic works as expected.Is the lack of presence of vlan 18 a factor as to why gc2960 is not receiving the tagged packets correctly? Should the interface vlan18 on gc2960 have an ip address on the vlan 18 network?

I just updated my OS from Windows 7 to 8, and I bought a new Galaxy S 3. Nobody seems to be ready for Windows 8 functionality. I don't know how to find the bluetooth feature of my laptop anymore now that I have windows 8 installed. My phone scans for it, and can no longer find it.
I have connected my phone to the laptop, it installs the phone, but cannot find the photos and videos that I have on my phone, even thought there are tons of them.
I thought perhaps I could Bluetooth them to the laptop, but so far, it's been nothing but a frustrating morning trying to locate the bluetooth function, and Dell's website doesn't seem to understand that people actually upgrade their systems to Windows 8, so there's no support there as far as drivers go.
I've got an Inspiron 17R, conveniently out of warranty, service tag <ADMIN NOTE: Service tag removed per privacy policy>.

I have an Acer Desktop Aspire AM3100 running Windows 7 Ultimate. I upgraded my memory. When I turned the PC back on I had lost my whole home network and cannot get internet acces back. I have checked my modem by direct connecting it to my laptop. I have checked my linksys box by doing the same. I can see the linksys on my laptop but cannot access the internet. On my desktop I get nothing?The home network and internet access all disappeared when I upgraded memory.

I tried to upgrade the firmware of my WRT350N but while upgrading my wife switched on the oven and.... yes, power down -> the upgrade has been interrupted. Now the router is no longer responding, it shows just the green power light on (not blinking). I tried all the resets I found googling (pressing the reset button for 30 sec, isconnecting power and reconnecting it again) but no way, there's no way to ping the router at its default address 192.168.1.1. All the leds are switched off (internet, usb, wireless, security) except the green power light. Is there another way to have it back or it is definitely lost?

For some strange reason I was looking at my router and wanted to check and see if there were any firmware upgrades available. I was not having any issues. I noticed that there was an upgrade and one of the notes indicated that it fixed some speed issues. I saved my config before upgrading and reloaded config after upgrading the firmware.Since the upgrade, I have lost connectivity to my printer and have intermittent issues with my remote dvr.The printer is connected wirelessly thru a wet610n.The dvr is connected wirelessly thru a wet610n.I can ping the printer, and I can access the printers web page. The issues appears to be two-way communication.The printer is an HP Officejet 6500a and allows eprint. The printer can no longer contact the eprint server.I have turned off my firewall on my computer and still cannot pring (why would I have to change this anyway, it worked before.)I use a ddns server for software access to my dvr. It worked flawlessly before.Now, the dvr is visible sometimes and sometimes it's not.
My wrt610n is v2 hardware.I called for support, but of course since the warranty has ended, support has ended unless you pay.Nothing like a firmware fix to break your router.I am very disappointed with the upgrade and the support provided.

We have 2 6513 switches with SUP720/PFC3A and various POE modules and a 6748-GE-TX facing our servers. Additionally, we have a 4Gbps portchannel trunk interconnecting the switches. We have approximately 300 Nortel IP 1140e phones in use between the two switches.For the purpose of call recording, we've attempted to mirror the voice vlan using various approaches and have been met with limited success. We mirrored the VLAN using tx, rx, and both. When using both we appear to get duplicate packets at the destination interface.We seem to lose packets completely going in one direction or another for a given call. Packets are lost before they get to the destination interface?

I often have to change switch ports to different VLANs. Regardless of whether I find the ports myself or if someone tells me what the ports are, I'll always perform additional verification steps to make sure that the port I'm changing doesn't connect to a switch, a router, a server, or something else that's equally important. But mistakes happen, and I have accidentally changed the wrong port to a different VLAN, thereby disconnecting the end node.
Is there a way to configure a port so that it will not allow you to change its VLAN (or make any configuration changes to it)? I'm imaging a command that when applied to a port would not allow you to make config changes to the port until you remove that command from that port, at which point you'll be able to change its VLAN, shut it, etc. If there isn't such capability, what strategy do you use to minimize the possibility of accidentally changing trunks, routed ports, or important access ports to different VLANs (other than labeling and verify)?

Apparently on older switches you could just enter the "management" command under the new VLAN interface and it would pull the config from the old one, apparently that feature isn't around anymore. I've tried establishing a trunk to the damned thing and trying to switch over that way, but it doesn't seem to work.

We've got a SG200-18 switch that is to be used as a workgroup switch in our environment (SW Version 1.1.1.8). Working with CLI on big and mid-range Cisco-gear over the past two decades I'm having a hard time figuring out the following on the SG200:
o) I want to change the Management-VLAN from the default "1" to the management-VLAN used in our environment. Sure enough I created that vlan in the SG200-config, however when it comes to assigning the management-IP and VLAN for the management interface in the corresponding pulldown under "IPv4 interface -> Management VLAN" the only thing selectable is the default "1". (see screenshots enclosed)So how do I set a management VLAN different from 1?
o) How do I enable telnet/ssh-access to the SG200-18 - I'd be far more comfortable with a CLI-environment?

I have several closets with Cisco 3560 on the edge that I'd like to change the vlan that's used for the management vlan on each. In the core I have a Cisco 6509 with Sup720's.
I'd like to do this by changing the native vlan on the trunk port on the core 6509 interface that connects to the 3560. and leave the management vlan on the 3560 as vlan 1.
Seems trivial but what I tried didn't work and I didn't have the window to troubleshoot. I'll paste the simplified configs for the interfaces below

6509 configs:

when I was using image 1.0.0.27, I was able to move the management VLAN from 1 to which ever VLAN I wanted. For some reason, after switching the image to 1.1.1.8, I no longer have that function.

I want to give a breif overview of the current setup and what I had planned to do in the future. This is also where a few questions come into play. Currently we have 3 10.x.x.x subnets between three buildings with a wan connection. This connection is invisible to us so it can be seen as just a lan. The speed is 100mb. We have a 2811 router sitting at each building translating their traffic back to 10.3.1.1. We then have a router in the main building which ships the 10.3.x.x traffic to a ASA and then out the door to a ISP.
My plan was to upgrade this 100mb WAN connection to 10g fiber between our buildings as they are in extremely close range of each other. I would need a equipment upgrade as a 2811 won't support 10g traffic. Rather than replacing 3 routers in each of the buildings it seemed logical that I could get something like a catalyst 4500 or 6500 and do int vlan routing making it all one huge campus lan. Creating a vlan for each building to segment the traffic between them. My understanding was that a cat 3500/4500/6500 did not need a router with sub interfaces in a one arm setup to bridge this traffic. This is where the problem comes in.I tested with a cat 3560 and was unable to get the vlans to route correctly. Do I have to have a router to get int vlan routing to work? If so then I might as well get a Router which can handle multiple 10g fiber for the core instead of a cat 4500/6500 since I'd need the router to do the int vlan routing anyway?
