In tunnel node 4 2930M/F switches are stacked, so there are 4 physical switches and it is 1 logical switch group.

From a controller perspective stacking switches are considered as one switch. Therefore one license is needed for the "Per Port Tunneled Node" feature. Currently there are no licences needed for the "Per User Tunneled Node" feature.

I have to set up a aruba controller (7240) in hub and spoke environment , in 2 spoke we have to install total 80 aruba APs(325).
What is the best design for this architecture ???
How many controller will reqiure for this setup ???
And which precaution we need to take for configuration & installation ??

You should start with the Aruba Networks Campus Network Validated Reference Design Guide here: http://community.arubanetworks.com/t5/Validated-Reference-Design/Campus-Network-Design/ta-p/155134
In Aruba it is called Master (writeable controller), local (read-only controller), not hub and spoke. According to the datasheet here: http://www.arubanetworks.com/assets/ds/DS_7200Series.pdf a 7240 can terminate 2048 access points, so if you are not going over 2000 for each site, in theory you could use 2 7205s. Please see the rest of the Campus Validated Reference Design guide for design ideas.

Not sure on your exact configuration but traffic shaping is possible. Have a look at Traffic Management configuration guide with QoS or Calssifier based policies.
No problem more than happy to help.

Are SFP 10G backward compatible with 1G speed ?
One of our customer has some errors on fiber link and suspect it is not compatible with such speed and asks to downgrade speed in the configuration.
Is it possible or should I recommend to swap 10G SFPs with 1G SFPs on this uplink ?

AFAIK a SFP+ (read: SFP Plus) Transceiver goes at 10 Gbps Full Duplex, not any lower speed like 1 Gbps (a SFP Transceiver - withouth the Plus suffix - works at 1 Gbps Full Duplex), so you can't down rate a 10 Gbps SFP+ Transceiver's port speed as you would do on a typical RJ45 10/100/1000 Mbps copper port (the SFP/SFP+ Transceiver sets the speed and the Switch slot in which that Transceiver is inserted lets it to communicate with other switched ports, you can't change the Full/Half Duplex Mode or the Speed).
So if you're using a SFP+ Transceivers pair the fiber optical link should be up at 10 Gbps Full Duplex (provided that the Fiber Optic link is clean OK).
The only way to go at 1 Gbps Full Duplex is not using a SFP+ Transceiver but using, instead, a SFP one.
Which SFP+ Transceiver(s) and which Switch(es) are you working on exactly (HPE/Aruba SKUs would help)?

We are going to purchase 2 x 2930F switch and use vsf to form a stack. Considering the actual requirement, we have some technical questions.
1. The switches are going to be located on different floor and connect by the fiber cable. Can a single fiber cable be used to setup vsf and transmitting the network traffice? Does it need seperate cable for vsf stacking and traffic?
2. Is the vsf on 2930F function similar as the modular backplane stack cable, the larger the line rate (e.g. use 10G SFP+ interface), the more the backpane bandwidth it can offer between the stack member?
Thank very much.

VSF between two Aruba 2930F can be deployed using a VSF Chain Topology (VSF logical port 1 on Member A <---> VSF logical port 1 on Member B), you can use a single physical interface bound to the VSF logical port (on each side) or, if you can reserve more physical similar interfaces, you can aggregate more ports together as VSF logical port's members.
In your scenario (just one single 10 Gbps link between A and B) you:
- can use that single link and bind it to the VSF logical port you're going to create (on each side). The VSF port carries all the traffic between the daisy chained VSF Members so you don't need anything more than that.
- basically yes, VSF is a software implementation Virtual Switching technology that uses frontplane traditional 1G/10G/40G Ethernet ports (40G on selected Aruba models) instead of using dedicated backplane stacking ports (through dedicated stacking cables and stacking modules). The more you bind the better the VSF link resiliency and throughput (basically as it happens when you use dual stacking cables - instead of just a single one - from a 2-ports stacking module on Switch 1 to a 2-ports stacking module on Switch 2...see Aruba 2920 as example).

Greetings! New to the HP/Aruba world. I have a 2530 running YA.16.02.0012 and there are certain things I'm trying to configure, but I can't find a syntax reference for this software image.
I'm trying to figure out how to set a native VLAN (4) on some ports, but leave the rest in native VLAN (1). Anyone point me in the right direction for that?

Since your Switch is currently still running on YA.16.02 Software Branch...have a look at these guides: here (for Management and Configuration) and here (specifically for VLAN concepts and implementations).
Actually it's a little bit difficult (or not easy as before) to look for and find documents about all HPE products (see reasons explained in this hot thread on HPE Community forum...basically because HPE redesigned very recently the HPE Support Center launching in a sort of still-Beta phase breaking the way we are used to look for and find documents and softwares)...so please take my links as examples (I had to filter with "16.02" all provided results for 2530 to find those links).

IMHO that data is probably a maximum value...since VSF maximum throughput strictly depends (and varies with) the number (and type) of VSF logical port's physical members interfaces that are aggregable together to form the VSF logical port (forming a "load-balanced aggregate VSF connection with redundancy").
AFAIK the Aruba 2930F supports up to four (4) 10G physical interfaces (ports) for VSF logical port...and can use up to two (2) VSF logical ports (called simply VSF ports)...so the 80G limit is the maximum in a 2 VSF logical ports configuration made using 4+4 10Gbps interfaces.
Using specifically 1G physical interfaces (a scenario not permitted on Aruba 5400R zl2 VSF implementation) will let you - if I've read it correctly - to aggregate (to bind) up to 8 1G physical interfaces per VSF logical port (so a grandtotal of 8+8 1G - so a maximum of 16Gbps VSF throughput - considering you can deploy up to 2 VSF logical ports).
In Aruba 5400R zl2 with v3 zl2 Modules the (2 members) VSF can be deployed using single (or aggregated) 10G and 40G physical interfaces only...not 1G (and in a either/or implementation, not mixed)...so it boils down to the number of 10G or 40G ports you're going to reserve for each VSF logical port.
If my algebra is still OK and rules above are valid...on the Aruba 5400R zl2 you can deploy up to 8 40G physical interfaces per VSF logical port, up to two VSF logical ports as in Aruba 2930F? NO...as of today I think that Ring topology (so 2 VSF logical ports on the same VSF Member) is not permitted on Aruba 5400R zl2...it supports only VSF in Chain topology...so we go back to the 8 40G physical interfaces per one VSF logical port case on each VSF Member...this means a theoretical 320Gbps VSF throughput between the two Aruba 5400R zl2 VSF Members when using up to 8 40G ports...or just a theoretical 80G VSF throughput when using up to 8 10G ports to form the single VSF logical port as is actually permitted (not considering the potential oversubscriptions behind the corner and/or the 80Gbps bandwidth limit per slot on V3 zl2 Modules when the Aruba 5400R zl2 works in "v3 only mode").

I just bought a new aruba 2930f. I noticed that I could go to web gui using any IP that I configured. How do I change that using only assign IP for web-gui and how do I to web-GUI using hostname like switch1.company.com?
Thanks in advance.

You can restrict access via the “ip authorized-manager” command. You can either make it via specific host (22.214.171.124/32) or via subnet (126.96.36.199/24). You can also lock it down via web GUI or other methods of access (ssh/telnet, tftp, snmp).
Switch(config)# ip authorized-managers
IPV4-ADDR Authorized manager IPv4 address.
Switch(config)# ip authorized-managers 188.8.131.52
access Define an access level desired.
access-method Define an access method desired.
IPV4-MASK IP mask defining a group of adjacent manager IP addresses.
Switch(config)# ip authorized-managers 184.108.40.206 255.255.255.255
access Define an access level desired.
access-method Define an access method desired.

Hopefully that anwsers your question!
