Have a small stack of two 3750 routers. Get the following error message every few secounds:
%STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state DOWN %STACKMGR-4-STACK_LINK_CHANGE: Stack Port 1 Switch 1 has changed to state UP
Now I replaced the stacking cables but no joy. It was ok for an hr or so but then the error messages popped up again. Also random links on this stack back to access layer user switches have been going up and down randomly. So I have decided to take the next step and upgrade the IOS.
Although when I try and copy a new IOS I get the following error:
%Error writing flash:/c3750-ipservicesk9-mz.122-55.SE6.bin (No space left on device)
Seems this image is 130MB while the image that is currently on it is 74MB and free space is 54MB. How do I get the image onto the router? If I delete the current image from flash will that cause the router to stop functioning?
Also I noticed there seems to be more than one flash directory. See below:
copy tftp: ? flash1: Copy to flash1: file system flash2: Copy to flash2: file system flash: Copy to flash: file system null: Copy to null: file system nvram: Copy to nvram: file system running-config Update (merge with) current system configuration startup-config Copy to startup configuration system: Copy to system: file system vb: Copy to vb: file system
The current router image seems to be in flash1 and flash 2 also. Could I delete the image from flash1. Upload it there and then boot the router from flash1?
We are running a small network business and as funs of ciscos we own a some of the 4948s.We are facing an issue with couple of them as we get the below error message
C4K_CHASSIS-3-INSUFFICIENTPOWERSUPPLIESDETECTED:Insufficient power supplies present for specified configuration
First thought to replace the power supply didn't actually work as we did that with no result.Power consumption is not an issue as well because all other 4948s work fine with 1 power supply (forgot to mention is 1 power supply in all of them).
I recently upgraded my network to have two 3750x core, one interface on the Cisco is connecting to a Net gear switch via a fiber converter. I am keep getting the vlan flapping error message in my log as below.
003396: Sep 17 01:46:16.328: %SW_MATM-4-MACFLAP_NOTIF: Host 5c0e.8ba7.0a5c in vlan 2 is flapping between port Gi2/0/15 and port Gi2/0/13 003397: Sep 17 01:46:19.843: %SW_MATM-4-MACFLAP_NOTIF: Host 5c0e.8ba7.0a5c in vlan 2 is flapping between port Gi2/0/15 and port Gi2/0/13 003400: Sep 17 01:49:58.769: %LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet2/0/17, changed state to down [Code] .....
After my research i think this is a looping issue but I'm unsure how to address it.
after a certain period of time (ranging from 2 minutes to several hours) the unit keeps dropping the WAN connection, making the unit unaccessible from the WAN side. The strange thing is, that when the connection is dropped, the unit is perfectly accessible from the LAN side, the WAN LED is still on, status info shows the WAN link up, and packet trace shows broadcasted traffic on the WAN interface, so only the directed communication to and from the ISPs gateway (configured to fix IP) seems to be blocked for some reason. When this happens, then plugging the WAN cable to the Optional WAN port enables traffic again, but it is also dropped after some time, and then only power cycling the unit restores WAN connectivity.
I am receiving this error after connecting a copper adapter on a GBIC blade in a 6509. Here are the results from the show Interface. I am waiting to confirm the device on the other side settings but as far as I see I get UP and Up for protocol and line respectively.

I have Nexus 7K installations in 2 locations. Both of them have multiple VDCs. In default VDC there are continous tacacs error message though tacacs is not configured. The requests are from various public IPs where thsi VDC is not exposed to Internet at all. What would be t he cause of it?

1. When creating job or log file, these files are always stored in the default Path (inside LMSROOT) for RME for example...Could I change RME default Path to store these files in another location inside the Hard Disk?
2. Could I Configure CW-LMS to send all the reports to me by mail?
3. What is the Difference between Poll Interval time and Collection time inside RME?
I have a 3750X stack of 6 switches, I have a terminal server console server plugged into the console ports of all 6 switches. I am having a strange issue where I can connect to the master via the console, get a login prompt then I can log in, but when I try and connect to any of the members then I get a prompt "Press RETURN to get started" When I push return, it just loops back to the same prompt again:
switch-6 con0 is now available Press RETURN to get started.
switch-6 con0 is now available Press RETURN to get started.
I can connect to the stack via SSH fine etc. I am running 15.0(1)SE2. The stack is configured for TACACS+ auth via Cisco ACS.

Sometimes, either browsing from my computer, iPad or iPhone, I sometimes get a "can't connect to server" error, and it's not just a few forums here and there, it is a lot of them. But if I give them 5 or 10 minutes they will come. Imkmow that this isn't a normal up issue with sites servers actually being down. I thought it was a Google chrome issue, but it's been happening on safari. It hasn't started till we switched our Internet plan to 3mbps and a new router.
My wireless network connection appears to be working; I can access the Internet from my laptop, iPad, iPhone, but not from the Dell PC that is the 'host' computer. Local Area Connection 2 Status window shows it as working, when I try to repair it, I get hung up with an error msg:
>>"Windows could not finish repairing the problem because the following action cannot be completed: Clearing NetBT For assistance, contact the person who manages your network." <<

I just got myself a Cisco RV220W, connected my laptop to configure it. I receive an IP adress by DHCP (192.168.1.x) and can ping the router (192.168.1.1). However, when I try to connect to the router by the web interface, I receive this message in my browser (Chrome):
The webpage at https://192.168.1.1/ might be temporarily down or it may have moved permanently to a new web address. Error 113 (net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH): Unknown error.
In FireFox: Secure Connection Failed An error occurred during a connection to 192.168.1.1. Cannot communicate securely with peer: no common encryption algorithm(s). (Error code: ssl_error_no_cypher_overlap)
In IE9: I get no error message, the page never loads
Is it DoA or how to get connected to the web interface?
I have installed a cisco 2911 router and the cisco usb console drivers on my pc, win 7 64 bit.however when I use putty and open the com port assigned it just goes blank, I am using the usb port on my laptop to connect and using the cisco usb console cable provided
Yesterday my router was hangs and my services was stuck. I start the router hard booted and it works fine.This was second time i was facing this kind of scenario. The attached are the "show tech support" of the cisco router 2821.
We've got Cisco 2821 for our 90mb/s Internet Access. Its CPU usage is around 80%. Show process cpu does not show any cpu proccess with high utilization. But we have got plenty of policing configured for our clients using policy maps. Can this policing affect cpu usage?
I have customer that we have configured netflow on the 2821 router that their traffic is on. Currently the company they have contracted with for the analysis is seeing data duplication. Below is the configuration for the interface and the router
