Hi All,

I am having problems loading OS image onto a new Nexus 9504 with 2 sup below are the steps i have tried, any advise would be much appreciated. image i am using is nxos.7.0.3.I5.2.bin

1. Reload switch and
2. Ctrl + C
3. cmdline recoverymode=1 and cmdline init_system
4. boot nxos.7.0.3.I5.2.bin (which is copied on bootflash/)
5. After this it starts configs and took some time but displayed other messages: System is coming up ... Please wait ...
6.After this, it returns to bash shell: bash-4.2# and nothing happens
7. Both switches, I have reloaded twice and retied again; but still same.

when i exit it takes me into (standby) login: but requires username and password which i have tried all the defaults and will not let me in.

Thanks

Hi
Someone must be using "route based on physical nic load". I wonder how the uplink physical ports to be configured? LACP/LAG whatever in Cisco term.
We have Cisco 3850.

I'm at a client which has an Internet feed from their Israel office which egresses in NYC. Nobody seems to know why it was put in that way. Might any experts on here with middle east experience know why you might want to egress on the other side of the Atlantic rather than just using a local ISP? Or at least Europe? Security issue? Tax issue? Something else??

on the topology above , I have R1 and R6 on AS 1, R5 on AS3 , R2,R3,R4 on AS2

I would like to have Routers on AS1 (R1 and R6) Not take route through AS3 to reach routers inside AS2, instead I want AS1 routers to go straight to AS2 through R1 using BGP Default Local Preference command on R1

you can see in the config below on R1 :
bgp default local-preference 600


Below is the BGP route configuration on R1, R6, R3. As you can see R6 is going through AS3 to reach routers in AS2 instead of going straight to AS2 through R1

If you need more info , please feel free to ask.


Thank you

interface FastEthernet0/1 - 20% (4Mbps Link)
interface FastEthernet0/0/0 - 30% (2Mbps LInk)
interface FastEthernet0/0/1  - 50% (2Mbps LInk)

why every time traffice use primery interface as a interface FastEthernet0/0/1, please suggest what need to be changes for traffice move in order, example:-
interface FastEthernet0/1 - 60% (4Mbps Link)

What is the process to logon to or reset the logon username and password for a SonicWALL TZ600 router when the logon information isn't known?

We don't want to reset any information on the router we simply want to logon to it or reset the username and password.

We have physical access to this router.

How can this be done?

Hi experts,
i need some advice. i have about 50 pc's on our company network with 1 file server that these pc's access for AD,DNS, DHCP and our financial application(uses access database). we currently have a 48 port 10/100 switch with 2 gigabit uplink ports as the backbone and then 2 gigabit switches connect to this backbone switch. i was aiming to replace the 10/100mb backbone switch with a full gigabit switch but budget is a problem at the moment. would the following work as a temporary solution for about 3 months: I will install a very entry level 8 port dlink gigabit unmanaged network switch as the backbone, connect my server and links to other switches to this 8 port switch. so from the 8 port switch i will connect all 4 network cards on my server to this switch as well as the link cables from my 3 larger switches. I know this is not the best solution but i just need something that will do the job for a few months? or would this small 8 port switch take too much strain?

can I ask a few basic questions in relation to Symantec backup exec.

1) what is the underlying database which stores all the configs, e.g. sql server or something else?

2) where is the management console can you see which accounts are authenticated for access? is access based on windows logins or accounts specific to backup exec?

3) in terms of the management console configuration, what needs to be backed up?

4) and is there an easy way to export all the current settings, e.g. jobs/schedules, backup selections per server (e.g. which drives) alert configurations and recipients, out to a single file for offline analysis?

5) is it application aware, e.g. by default does the standard package have the ability to backup exchange, SQL, AD, sharepoint etc.

Via AWS I spun up a Windows Nano Server node. I can manage this from a management server in the same VPC.
 
Using Powershell, I can access the Nano server, add the server to my network domain, create a sheduled task, create a local user group and add a domain user to it, assign user privileges to allow users in this group to run scheduled tasks.
 
This scheduled task shoud read and write to locations on our networked SAN, which lives in the same VPC.
 
But the Nano server does not allow access to the SAN.
 
if I use the Powershell Test-Path cmdlet, specifying the UNC path to a location on the SAN, it complains that access has been denied.
 
And yes, the domain user has complete access to the locations on the SAN.
 
I also tried mapping a drive letter with net use: same result.
 
I have read every document by Microsoft and every blog post and StackOverflow post I thought relevant. Only 1 other person described the same problem, and has no solution. They were on a forum for Docker, and the Docker team discovered this is a problem with Nano, and not with Docker.
 
In my set-up, I don't use containers, I don't use Docker. I guess AWS runs this Nano instance in Hyper-V, but that is outside of my reach.
 
The Samba firewall ports are open and active (File and Printer Sharing).
 
Have you encountered this problem? How did you fix it?
 
One way I can work around this problem is by reading and writing to the Nano server itself. However, I fear that such would …

aside from SQL Server databases, what other types of files would need special/app aware backup processes. My understanding (albeit I am not a backup admin) is most default backup solutions don't backup live running database files, so you typically have to use the DBMS backup features and then use your backup solution to 'backup to backup'. I just want to do some assurance work that the backups our admins are doing is either using an application aware product which can handle running files such as databases, or whether they are using other tools such as the DBMS in built backup features to do them.

also apart from SQL databases, what other files need special backup arrangements, e.g. what else would not be covered by standard backup programs, in your standard windows network environment?

I set up a Linksys LRT224 router about a year ago
it does some pass-throughs ti the following
-security camera NVR only two users can access

-Windows Server 2012 running an SQL database about 10 users

-VPN connection so users can get to all servers and appliances
This was suppose to be for only two users, but now they want all 10 users to be able to use VPN

Question?
should I continue to use this router? will is start to degrade in speed
some users say the VPN is starting to slow down

any suggestions are appreciated

Dear, I got this error from today morning. All the servers in this network range could not be accessed like attached screenshot.

When I tried to access these servers from the same ISP (which provide this network range to us), the servers COULD be accessed; but when I tried from other 2 ISPs, they COULD NOT be accessed.

The servers are Window Server 2012R2 Standard, have Kaspersky, Firewall but they are configured properly, nothing change (this error started from today morning)

Can you please suggest?

we are doing some risk assessment work on backup processes from a risk management perspective (we have no responsibility for doing them ourselves), aside from servers, which host the critical data/files, what other devices in a network need considering in backup policies, so we can interview the department responsible to see that they are included/tested.

what documentation would you expect to see an IT department have in place specific to their backup/restore processes? I am trying to get a better idea of the process from a risk and compliance angle, but need to identify either some useful probing questions for the team who do backups, or request some documentation that you would expect to be in place.

Hi,

Let's say I'm an ISP and I lease a 10G transport pipe to an IX (Frankfurt or Amsterdam), with the purpose of buying transit from 2 different tier 1 providers (2 resellers, probably) and peering with content providers.

What happens inside the IX?

Do I get one switch port and I have to rent rack space for my own equipment there? The peerings are physical, with cables between my switches and the peer switches?

Or I only get a VLAN and the peerings are inside the IX main router/switch? And I route the traffic from my VLAN to my peer's VLAN?

Or?

I've googled for the past days, but I'm still confused. Anyone has real world experience with this?

Thank you.

Hey Jim on the off topic concerns, we are seeing an increase in traffic overall based on our efforts. See more information here
http://blog.experts-exchange.com/ee-blog/community-update/

I looked at the stats for the My SQL Server topic and the questions asked, excluding deleted, were up year over year for April and May but saw a decline in June. I'll see if I can find further indications why this is the case.

One thing I use that you may find useful is Google Trends. It can help you see how in general search terms are trending.

https://trends.google.com/trends/explore?date=2015-06-12%202017-07-12&q=%2Fm%2F0120vr

(reading for the first time)  Nice article.  Gotta like that action.  I suppose it's difficult to interpret results and do a cause-and-effect to what EE initiative led to the increase(s) in volume.    

It was very unexpected when Gene agreed to sponsor my SQL Saturday last year, to include free memberships, and was disappointed when that didn't translate to signups.  Perhaps I need to rattle a few cages in my local SQL community.

One thing I never really understood (keep in mind I'm not an SEO guy) is why tags were discontinued from articles in place of the question title.  Last year I tried doing a Google search for keywords that should have resulted in my articles in the search results (SQL Server GROUP BY, SQL Server CASE, etc.) and results were not that hot.  

For some reason my two Requirements Document Template articles get significantly higher views then the other articles.   Maybe I just nailed the title correctly.  A Google search for 'requirement document template reporting' shows my article as #2.
