That is correct. Configuration remains in flash and gets loaded in ram. For a firmware upgrade if you are making a huge jump, some commands may not work. Vlans are in a different file so yes running config remains unchanged.

I can only do these lab because of having access to devices and licensing. Aruba CX switches can be learned using virtual images. That is free but rest will all require licensing.

@@TwT101 hi I have access to the license but I’m struggling to set it up with the right for the switches we have in my work place 3810m for core and 2540 for edge so can you please telll me which imgage I need . As the Aruba cx I have on GNS3 is different

@@XwolfBane18 3810M and other Aos switches doesn't have virtual image. Only CX has that. Email me your issue.

@@TwT101 could I please get your email . I am aware of the Aruba cx doesn’t have the 3810M but how can I implement it on GNS3 if I can get the image etc . Thank you for your time .

@@TwT101 will email now :)

I was simulating a power outage and mistakenly pulled power on standby first, hence standby came up before Commander. Later I did a boot system so the whole stack restarted and I was able to show that the commander stayed commander. Are you getting certified? Let me know what other Aruba products you have worked with.

@@TwT101 Ah thanks for explaining! No not getting certified, I have a deployment coming up that uses 4 of these Switches in a Stacked Configuration, I’ve worked with these series of switches before so I’m just brushing up on my knowledge a bit. Only other Aruba products I actively use is the Aruba Instant-On switch series.

Hello @networkprofessional what technology lab are you interested in?

Thank you

Reach out to me if you want to learn this.

@@TwT101 I want to setup orchestrator lab to work on it.. please do help

Thank you so much for your review. What QoS configuration are you looking for ? Usually if you are not overwriting the QoS markings, trusting dscp and cos does the job at switching level.

I truly lack this side with sounds, effects and other aspects of making videos. I hope the topic helped you in learning. I will attempt to do better for sure.

Thank you

I would love to hear that. Thanks @chucksw1 reach out to me if you need anything with Silver Peak.

I can lab it up and let you know.

Sorry, it was one of my first videos and it was long so I had to speed it up and it distorted the audio.

@@TwT101 Hey, you did a great job! Don't worry about duration as engaging topics such as these are the reason that viewers enjoy your videos.

It's Eve-ng. This one with Pro license. I also have a free community version installed that I let my students play and lab stuff.

Other than that I hope this video was helpful.

@@TwT101 i think so. Bravo 4 the share and especially the time u took 4 this deep dive VPC immersion!

In short tar is a zip file that has other packaged files which get installed. Also doing it this way also sets your boot parameters.

Hi Manoj, you can do a mlag with your firewall and connect them to both core switches. Allow the transit vlan and create SVI on each core for that vlan and an L3 interface on your FW. The default route to that IP will take care of the rest. There are other ways like VARP in Arista that makes both the cores active in transferring upstream data. Email me your contact we can talk.

Lots of background humming noise from servers. To hide that, I thought music would be nice. Again it's just the aesthetic, that shouldn't affect learning the concept. If you have questions please let me know.

Thanks. Are you working on a project or prepping for Certs ?

If you have the switches configured and connected, stack can be built using SSH as well. In most cases this is done during 1st setup process, hence mostly done using console. I build the base config, build the stack and mgmt ip using console, then I blast rest of the config using SSH as it goes in faster this way. Hope this helps .

Thanks!!

This is an old way of doing load balancing. Even vlans root be in core1 and odd vlans root will be core 2. Even vlans SVI will be active on core1 and Odd clans SVI will be primary on core 2. Things have improved a lot since then. You can do an active gateway where both cores are actively responding for the gateway role.

Thanks for your review. Keep learning.

Thanks for your response.

You have the CX switches and this was done on AOS switches. If you need help email me support@tutorialswithtips.com

@@TwT101 thanks for taking the time to reply :)

You shouldn't be thinking about the sizing of DZ controller. It's the vendor who will be doing it. But for all 100 APs yes they will have to size the controller accordingly. Remember it's their SSID and if they need RF and pefng they will have to buy those licenses as well. Most of the time it's a smaller group of APs used for multizone. For example at the shopping mall Levi store only need a set of APs near Levi store front to broadcast SSID and not all over the mall. Hence DZ controller size usually much smaller. Hope this helps.

@@TwT101 Thanks a lot

I have upgraded thousands of Cisco switches during an ISE deployment project. 1st day of that project one 3750x didn't come back up after the upgrade. That changed everything. Since then we added an extra step. Pre-upgrade reload to rule out HW issues. Once the switch came back up from that reload, we proceeded with ios upgrade. Are you afraid that the switch might not boot back up after so many days of running ? Let me know

Hi Aditya, Yes you are right, If you've purchased HW-5K you are now licensed to talk to 5K devices, e.g mobility conductors, AP' RAP's etc.. If you hadn't purchased the HW and went with virtual appliance for MM, You would've needed MM-VA-XX license to able to license X numbers of devices. I am so sorry to answer this so late. Hope it helps.

Unfortunately Aruba AOS doesn't have the command but they included that in new Aruba CX switches. Also context sensitive help sucks for AOS switches. For example if you are in interface config mode Aruba-3810M(ethe-1)# ? It will show you all possible commands available in config mode. Hope this answers your question.

Devices like printers are not talkative, so their Mac times out while arp entries remain on L3 interface. New packet destined for that printer from that vlan or a different vlan will use arp to identify the switch where that printer was connected. It will be a unicast and directly sent to the switch. Switch won't have that Mac on it's cam table and for security it will drop it. Unknown Mac broadcast it would've forwarded out all its port but unknown unicast is blocked by default. Let me know if it makes sense

@@TwT101 So disable Eavesdrop Prevention on ports that are connected to printers, but okay to leave it enabled on ports connected to computers? What about ports that are configured for STATIC and LIMITED-CONTINUOUS, what 's the best practice?

@@chasuav I would disable eavesdrop prevention on all ports unless you have printer connectivity defined for printers j. Your organization. I also believe this was fixed at a later AOS version. Please check. Limited-continuous is a feature where until the Mac address limit is reached the switch will continuously learn mac-addresses but once reached then it will stop learning new mac-addresses. Kunal@tutorialswithtips.com let me know about you, your current role, if you are new to Aruba and future goals.

Hi there. We have a manual and archive upgrade process explained for 3750x stack in this video. Please rewatch and let me know if you understand.

Man, I feel you. You probably on the same boat as me. Python and I have a love hate relationship. I don't do it enough to get this burned it. Hence I forget. I am glad this video has helped you. Keep up the good work brother.

How Rahim, this looks like an old switch. So found quick google search result that might be of help. community.hpe.com/t5/Comware-Based/Resetting-5120-to-default-factory-settings/td-p/6020893#.YuxUeLdOnqs

There is no such process to reverse this. You can leverage backup and restore to put the old unit back. Old unit was removed from Orch by RMA process so just take backwards steps . But my question is why would you want to do this ?

I think he was just looking for a back out plan:)@@TwT101

Thanks, are you asking me what software I used to make this video ?

@@TwT101 no sir i want to practice this configuration so is there any software you are using?

@@m.ammarraza3957 these are real hardware switches from Cisco and Aruba. Newer Aruba Aos-cx switches does have a virtual option that you can download and install on VMware esxi.

@@ushavingfun6426 Thank you sir for such a kind attitude, sir i have Aos-Cx installed in gns3 integrated with vmware but not all the configuration commands as i was taught by my teacher in physical Aruba switch are not running on this logical switch

@@m.ammarraza3957 you are right, Aos-CX is the new class of switches and different from previous Aruba AOS switches when it comes to commands. Remember to try the ? After your commands to find out what is allowed as a valid command. For example there is no reload command in AOS cx it's boot system

Thanks Kirk!!

Thank you

Thank you for your comment. My email address is in RUclips channel about page. Support@tutorialswithtips.com

I don't know what that means. Can you please share with me.

Hi the admin admin does not work for me. i have the version 8.10.15. do you know if there are others default password in last version? thanks

@@nordgonzalez3234 that has always been the default credentials. Can you reboot and try again. Next will be factory reset. Let me know.
