Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.

I am upgrading the Comware 5 firmware on HP 5120 switches HP 5120-48G-PoE+ EI Switch Product # JG237A. In the past I have upgraded them with they are offline.  I would use my laptop as a TFTP server, connect it to a port on the switch, and put my laptop IP address and switch management IP address on the same subnet. I would use the following commands (for example):

delete /unreserved flash:/<firmware>

tftp <IP Address> put flash:/<firmware>

boot-loader file flash:/<firmware>

save

reboot

Would I be able to do this with a live HP 5120 switch connected to the production network and grab the firmware off a live tftp server on the production network?

Please help. Thank you.

How?

I need to update a bunch of catalyst switches from TLSv1.1 to TLSv1.2. Also need to disable older ciphers. Has anyone implemented this before?

Please share the steps as I can't seem to find anything documentation online for this.

Thank you.

hi guys,

I'm currently managing an IT Operations team. I've been asked by our new head to come up with a way for me/us to measure in some shape or form their progress on a weekly basis.

We use Zendesk for our ticketing system which is very comprehensive. He wants us to find a way of knowing, how many particular jobs were started, closed, including things such as 'what got in the way?'. Along with that, he wants to know a way of measuring project progress in a similar way.

Do you guys have any measuring methods that you use at your work places? Or advised others on how to better do something similar?

Thanks for helping

HI
I'm just implementing a DPI inspection and I've download a key from my sonicwall firewall.
This cert. has been distributed to my PC over GPO.

my network is as follows:

Comcast 10.1.10.1

Sonic Wall - 10.1.10.2 (gateway 192.168.1.1)


Just double checking, I want the SonicWALL subnet to be private.  I am a little concerned because when I am on a workstation behind the sonic wall I can ping the Comcast gateway, and navigate to the admin portal.

However, when I am directly plugged into the Comcast gateway I cannot ping the 1.1 gateway subnet.  So the SonicWALL subnet is not visible to the main comcast network.  Is my network setup and secured as intended?

Where i work has a large number of DHCP scopes. must be approx 40-50 its been left that way for a good few years apparently

I have just joined in past 6 months and just getting round to look at it now

Any DHCP scope clean up plans? Whats the worst thing that can happen if some are removed that have VLAN connections (one thing we're worried about) so i plan on taking an inventory first

I know i can use powershell to look for free addresses per scope can i use this to see addresses that are taken, then i could compare using HP IMC to see whats actually being used

Any ideas appreciated domain functionality is 2008

Working in environment with 34 switches mix of hp 5500 and 5120s over 3 locations

I suspect that the company who support our infrastructure just took the default priority for spanning tree design with switches

I intend to check each BID on each switch is there an argument for using default settings for stp would appreciate best practice on this and and also pointers on easiest way to correct it

I have login for each switch but also use HP IMC

Thanks,

We have a connection to the Internet and now we just added another Internet connection. We want to use the new Internet connection just for Office 365. I am not sure how to go about doing this as I have a default route from my core to the FW and then from the FW to the provider router. So currently all Internet connection, including O365, is pointed to the default route and there is nothing going out of the the new Internet connection.
We have a physical connection from the provider to the FW, then from the FW to the core switch.

Any thoughts? Thanks

I currently have a SonicWALL TZ 200 configured with WAN connections on 2 interfaces. I recently purchased a HughesNET satellite connection and I want hook this up to the SonicWALL (And add it to the failover/load balancing). However, once I received the Modem from HughesNET (HT2000) I learned that it does not have a "Bridge" mode built into the router. I cannot disrupt my current Subnet (needs to stay the same). Does anyone know if there a way to configure the interface for the modem/router combo into the SonicWALL so it will work properly?

Thanks in advance.

In addition, can this switch become a DHCP server?  I dont believe so as the doc mention considerations when the switch receives DHCP config - but nothing on creating them. But I need to ask.  I will need a simple DHCP server for this assembly (SIP Phones using Free PBX) and using the switch would be ideal if it did work like that.

I have a client with whom I've set up a home group. He's got 3 computers with each having Windows 7 installed. Every evening he leaves his shop, every morning when he comes in, his computers and two HP printers have lost their connectivity. The home group eventually regains its settings, but he has to setup his printers from scratch. He changed routers recently. Before his router change, his network had no problems.

I have been informed by Spamhaus that the IP address we use for corporate email has communicated with a known spam site and is either infected by, or NATing for, a computer that is infected by the S_Gozi trojan / downloader.

It states that the infection is extremely difficult to detect and is not seen by most commercial AV or EndPoint protection suites.

I have been told to program the Sonic-wall TZ215 to stop all traffic to sites outside the US.  We have never done this before.  Not sure how to setup the sonic-wall for that purpose.  I know this virus does not use the standard port 25 for smtp traffic it uses port 80 which i cannot block.  It is extremely difficult to find so i am trying to stop its connections at the firewall level to stop it communicating.  Any help would be greatly appreciated.

Building/space already have multiple ISP provisioned.  Fibre and wireless.
Before building a network what information we need to know from ISP before designing and building things out?  Just making sure not missing anything.
I am inheriting an existing space with already provisioned ISP service.
Thanks in advance.

If anyone uses a dell 'power vault' device within their environment, do you know the name of the remote management application, and default login address/port number, e.g. can it be accessed via  a browser, or do you need to RDP onto the machine itself?

Also, as dell networking equipment is something fairly new to me, if you have 2 Dell Equalogic SAN's (one at a primary site and one at a DR site), and use backup exec for the backup application, what exactly is a 'dell powervault' for in relation to a disc-to-disc (SAN to SAN) backup process? e.g. what role does it play?

I have several Dell SonicWALL's in service but with one of them,  a TZ205 wireless-N, I can't remotely manage the Sonicwall.  I can connect to all computers at this remote location from a VPN tunnel, Site to Site.  If I connect to a PC behind that SonicWall I can then connect and manage the SonicWall.  This is an extra step that I don't want to have to deal with.

I've compared settings to my other SonicWalls's but none are the exact same model.  As far as I can tell everything is the same.

What am I missing?

I have a stack consisting on 4 WS-C3850-48 switches...
2 WS-C3850-48T CAT3K_CAA-UNIVERSALK9, Version 03.06.05E IPBase - INSTALL mode
2 WS-C3850-48P CAT3K_CAA-UNIVERSALK9, Version 03.06.05E IPBase - INSTALL mode

I want to add a 10 GB switch to the stack.  It is a...
WS-C3850-12XS-S CAT3K_CAA-UNIVERSALK9, Version 16.03.05 IPBase - INSTALL mode

I am wanting to use the basic Cisco documents about upgrading my current stack to 16.03.05 from 03.06.05E.  Are there any special considerations?  I am only a CCENT with limited experience.  I don't want to ruin my stack.

I am backing up my configs and VTP database.

I believe the switch can be added while the stack is on.  Is this true?  What order would I unplug the stack cables?
Since it is a stack, will each switch take turns upgrading and avoid any downtime?

for someone not familiar with tape backups, can you give a tech free summary of what manual daily processes would have to be performed by the staff who look after tape backups, and is this something that requires daily human activity, or weekly etc. I have just read about 'clean down' the tapes on another checklist, but as its not an area I am familiar with, I am unsure what it represents in terms of an activity. For any part of the backup process where there is manual involvement, we want some form of checklist that the manager can view to ensure all tasks took place each day, or if not signed off the manager can then assign a colleague to perform the tasks. I'm also keen from a risk angle to determine if someone did not do these various tape backup daily/weekly maintenance activities, what the actual risks could be to the overall backup process?
