Best Practice for Networking in UCS required

Hi
We are planning to deploy UCS n our environment. The Fabric Interconnects A and B will need to connect to pair of Catalyst 4900 M switch. Whats is the best practice to connect? How should the 4900 switch be configured? Can I do port channel in UCS?
Appreciate your help.

Kumar

I highly recommend you review Brad Hedlund's videos regarding UCS networking here:
http://bradhedlund.com/2010/06/22/cisco-ucs-networking-best-practices/
You may want to focus on Part 10 in particular, as this talks about running UCS in end-host mode without vPC or VSS.

PKGBUILD best practice for autotools and missing required files

I am trying to update one of my packages in the AUR. Upstream using GNU automake/autoconf tools and has worked just fine for previous versions. This time around, the download from upstream is missing several of the mandatory files required by autoconf. I am trying to figure out the best way to deal with this.
1. I can add just create them, and distribute them with the Tarbell, and push them into src directory prior to invoking autoconf.
or
2. I can use the --add-missing flag, but that requires the running of autoconf multiple times (unless I am confused)
What is the best practice when files such as NEWS and README are missing?

User Authorization, best practices for this custom application requirement?

JDeveloper 12c (12.1.2)
We want to use external LDAP (active directory) with ADF security to authenticate and authorize users.
One of our custom application requirements is that there is a single page with many interactive components. It has probably about 15 tables and each table would need to have the following buttons (or similar components):
- delete: (if certain row is selected) to delete it
- edit: (if certain row is selected) takes user to 'edit page' where changes can be made
- create: to create new record for this particular VO (table)
So let's say that would be 3 x 15 = 45 different actions that single user can possibly perform. Not all users have same 'powers' ie some users can only edit CERTAIN tables, and delete from one or two. Most users can create and edit most VOs etc
Back when this application was originally developed using (I believe) 10g JDeveloper with UIX, the way it was done is that we maintained a table in database with 'user credentials' as Y or N flags.
For example: DEL_VO1, EDIT_VO1, ADD_VO1....
So when user is authenticated we would then pull all these credentials from the DB table and load them into the session variables. Then we would use EL to render or not render certain buttons on the page. For example: rendered="#{sessionScope.appDelVo1 == 'Y'}"
Moving forward into latest ADF technology, what would be the best practice to achieve described functionality?

Hi,
ADF BC could have permissions added to the entity level (includes remove and update). So you can create permissions for the entity (as it doesn't matter for data security how data is accessed. If as a user you are nit allowed to change a database table then this is for tables and forms). You can then use EL to check the permission, thus no need to keep the privileges in the database.
If a user is allowed to update an entity then you can check this using EL in the UI
<af:inputText value="#{bindings.DepartmentName.inputValue}"
readOnly="#{!bindings.DepartmentName.hints.updateable}">

Best practices for network design on WLC 2504 and 5508

Dear all:
I'm looking for some recommendations on WLC 2504 and 5508 about the the following:
Maximum amount of AP per port
The scenario when to use all ports in both WLC
Maximum number of clients(users) per port
Bandwidth comsumption of management vs data in order to assign one port for management
I've just found this:
Cisco 5508 controllers have eight Gigabit Ethernet distribution system ports, through which the controller can manage multiple access points. The 5508-12, 5508-25, 5508-50, 5508-100, and 5508-250 models allow a total of 12, 25, 50, 100, or 250 access points to join the controller. Cisco 5508 controllers have no restrictions on the number of access points per port. However, Cisco recommends using link aggregation (LAG) or configuring dynamic AP-manager interfaces on each Gigabit Ethernet port to automatically balance the load. If more than 100 access points are connected to the 5500 series controller, make sure that more than one gigabit Ethernet interface is connected to the upstream switch.

Thanks for your help.

The 5508-12, 5508-25, 5508-50, 5508-100, and 5508-250 models allow a total of 12, 25, 50, 100, or 250 access points to join the controller.
This is an old document. 5508 can now support up to 500 APs if you run firmware 7.X. 2504 can support up to 75 APs if you run firmware 7.4.X.
I'm looking for some recommendations on WLC 2504 and 5508 about the the following:
Best practice and recommendation is to LAG all ports so you will be able to form a link redundancy. If one link goes down, you have other link to push traffic.

Sanity check - Best practice for network configuration

Basic configuration is this:
Physical server has two interfaces. Two different networks. Generically we reference them as Front End and Back End
Back End is dedicated to storage (nfs from netapp or Sun 74xx)
xenbr0 associated with eth0 (front end)
xenbr1 associated with eth1 (back end)
For each Virtual Machine, have been creating two interfaces; vif0 with xenbr0 and vif1 with xenbr1
The desire is to have all disk I/O use the vif1 -> xenbr1 -> eth1 path. So far it seems to be working that way.
Questioning the setup because we have seen this sort of error when shutting down a VM
nfs: server axqntap1 not responding, still trying
In case it matters, mount options inside the vm are: rw,bg,hard,intr,timeo=600,proto=tcp,vers=3,rsize=32768,wsize=32768
Any advice, ideas? Are we all wrong with the bridge config? Mount options?
Thank you - Randall

Shutdown applications within the guest.
Either power off from Oracle VM Manager or 'xm shutdown xxx' from the command line
It is possible one or more files could be open when the shutdown is initiated.
Have found at least one case of misconfigured IP which would have resulted in the disk access being via the 'Front End' interface rather than the Back End.
Thanks

Best Practice for report output of CRM Notes field data

My company has a requirement to produce a report with variable output, based upon a keyword search of our CRM Request Notes data. Example: The business wants a report return of all Service Requests where the Notes field contains the word "pay" or "payee" or "payment". As part of the report output, the business wants to freely select the output fields meant to accompany the notes data. Can anyone please advise to SAP's Best Practice for meeting a report requirement such as this. Is a custom ABAP application built? Does data get moved to BW for Reporting (how are notes handles)? Is data moved to separate system?

Networking "best practice" for setting up a farm

Hi all.
We would like to set an OracleVM farm, and I have a question about "best practice" for
configuring the network. Some background:
- The hardware I have is comprised of machines with 4 gig-eth NICs each.
- The storage will be coming primarily from a backend NAS appliance (Netapp, FWIW).
- We have already allocated a separate VLAN for management.
- We would like to have HA capable VMs using OCFS2 (on top of NFS.)
I'm trying to decide between 2 possible configurations. The first would keep physical separation
between the mgt/storage networks and the DomU networks. The second would just trunk
everything together across all 4 NICs, something like:
Config 1:
- eth0 - management/cluster-interconnect
- eth1 - storage
- eth2/eth3 => bond0 - 8021q trunked, bonded interfaces for DomUs
Config 2:
- eth0/1/2/3 => bond0
Do people have experience or recommendation about the best configuration?
I'm attracted to the first option (perhaps naively) because CI/storage would benefit
from dedicated bandwidth and this configuration might also be more secure.
Regards,
Robert.

Option #4 (802.3ad) looks promising, but I don't know if this can be made to work across
separate switches.It can, if your switches support cross-switch trunking. Essentially, 802.3ad (also known as LACP or EtherChannel on Cisco devices) requires your switch to be properly configured to allow trunking across the interfaces used for the bond. I know that the high-end Cisco and Juniper switches do support LACP across multiple switches. In the Cisco world, this is called MEC (Multichassis EtherChannel).
If you're using low-end commodity-grade gear, you'll probably need to use active/passive bonds if you want to span switches. Alternatively, you could use one of the balance algorithms for some bandwitch increase. You'd have to run your own testing to determine which algorithm is best suited for your workload.
The Linux Foundation's Net:Bonding article has some great information on bonding in general, particularly on the various bonding methods for high availability:

Best practices for setting up users on a small office network?

Hello,
I am setting up a small office and am wondering what the best practices/steps are to setup/manage the admin, user logins and sharing privileges for the below setup:
Users: 5 users on new iMacs (x3) and upgraded G4s (x2)
Video Editing Suite: Want to connect a new iMac and a Mac Pro, on an open login (multiple users)
All machines are to be able to connect to the network, peripherals and external hard drive. Also, I would like to setup drop boxes as well to easily share files between the computers (I was thinking of using the external harddrive for this).
Thank you,

Hi,
Thanks for your posting.
When you install AD DS in the hub or staging site, disconnect the installed domain controller, and then ship the computer to the remote site, you are disconnecting a viable domain controller from the replication topology.

Best practice for integrating a 3 point metro-e in to our network.

Hello,
We have just started to integrate a new 3 point metro-e wan connection to our main school office. We are moving from point to point T-1?s to 10 MB metro-e. At the main office we have a 50 MB going out to 3 other sites at 10 MB each. For two of the remote sites we have purchase new routers ? which should be straight up configurations. We are having an issue connecting the main office with the 3rd site.
At the main office we have a Catalyst 4006 and at the 3rd site we are trying to connect to a catalyst 4503.
I have attached configurations from both the main office and 3rd remote site as well as a basic diagram of how everything physically connects. These configurations are not working ? we feel that it is a gateway type problem ? but have reached no great solutions. We have tried posting to a different forum ? but so far unable to find the a solution that helps.
The problem I am having is on the remote side. I can reach the remote catalyst from the main site, but I cannot reach the devices on the other side of the remote catalyst however the remote catalyst can see devices on it's side as well as devices at the main site.
We have also tried trunking the ports on both sides and using encapsulation dot10q ? but when we do this the 3rd site is able to pick up a DHCP address from the main office ? and we do not feel that is correct. But it works ? is this not causing a large broad cast domain?
If you have any questions or need further configuration data please let me know.
The previous connection was a T1 connection through a 2620 but this is not compatible with metro-e so we are trying to connect directly through the catalysts.
The other two connection points will be connecting through cisco routers that are compatible with metro-e so i don't think I'll have problems with those sites.
Any and all help is greatly welcome ? as this is our 1st metro e project and want to make sure we are following best practices for this type of integration.
Thank you in advance for your help.
Jeff

Jeff, form your config it seems you main site and remote site are not adjacent in eigrp.
Try adding a network statement for the 171.0 link and form a neighbourship between main and remote site for the L3 routing to work.
Upon this you should be able to reach the remote site hosts.

There may be a few links in Apple Support, regarding articles about how to use iBooks Author
and iBooks Store, etc; these would be separated into two general categories by device used.
Since there is an iOS and an OS X version of each, you may have to look to see what Apple
Support says about the one you are interested in; and how far their database goes toward an
answer to your question. Otherwise, a general search engine approach may be necessary.
Not sure if anything along the lines of what you seek would be available in an App.
References to iBooks Author and iBooks Store, etc appear within these two categories in Support:
For Mac OS X:
http://www.apple.com/support/mac-apps/
For iOS:
http://www.apple.com/support/ios/
Appears a community host moved your earlier post into one of the iBooks Author or Store sections
after I'd replied to what otherwise may be a similar post. Not sure if the links to the Discussions area
of iBooks you are interested in, have similar questions or answers by others who'd visited previously.

ISE Best Practice for Purging Endpoints

Maybe I haven't looked long enough or deep enough through the documents and guides, but I am wondering if there is a best practice for purging endpoints in general. For my guest endpoints, I have it set to purge those endpoints every 3 days. When i look at how many endpoints I have profiled at the current time, its a very large number of devices. I'm sure there is a large number of these that are no longer connecting to our network and probably won't in the future.
If there isn't a current best practice, would it sound logical to purge every 180 to 190 days? We are a public school district and we have 180 instructional days. Employees and students alike are able to bring their own devices. I figure with 190 day purge, it would cover the time that employees and students are in session.
Thoughts, opinions?
Thank you for your time.
Kevin

A lot of vendors will suggest also to have one SSID if possible, but the rule of thumb is 3-4 max. The main issue is the differences required for specific WLAN's, which isn't just for Data and Voice, but you also have to look at mDNS, multicast, 802.11r, DTIM's, MFP, etc. You can combine all devices to use one, but all the features/setting will be the same, which isn't ideal all the time. There are attributes which you can set from ISE to push out to the WLC(s), but its the other unique values that you need to research and understand.

Best practice for RDGW placement in RDS 2012 R2 deployment

Hi,
I have been setting up a RDS 2012 R2 farm deployment and the time has come for setting up the RDGW servers. I have a farm with 4 SH servers, 2 WA servers, 2 CB servers and 1 LS.
Farm works great for LAN and VPN users.
Now i want to add two domain joined RDGW servers.
The question is; I've read a lot on technet and different sites about how to set the thing up, but no one mentions any best practices for where to place them.
Should i:
- set up WAP in my DMZ with ADFS in LAN, then place the RDGW in the LAN and reverse proxy in
- place RDGW in the DMZ, opening all those required ports into the LAN
- place the RDGW in the LAN, then port forward port 443 into it from internet
Any help is greatly appreciated.

Hi,
The deployment is totally depends on your & company requirements as many things to taken care such as Hardware, Network, Security and other related stuff. Personally to setup RD Gateway server I would not prefer you to select 1st option. But as per my research,
for best result you can use option 2 (To place RDG server in DMZ and then allowed the required ports). Because by doing so outside network can’t directly connect to your internal server and it’s difficult to break the network by any attackers. A perimeter
network (DMZ) is a small network that is set up separately from an organization's private network and the Internet. In a network, the hosts most vulnerable to attack are those that provide services to users outside of the LAN, such as e-mail, web, RD Gateway,
RD Web Access and DNS servers. Because of the increased potential of these hosts being compromised, they are placed into their own sub-network called a perimeter network in order to protect the rest of the network if an intruder were to succeed. You can refer
beneath article for more information.
