HSRP and Failover in a Setup

Hi All,
I need a create a setup with complete HA availability from Core Switch , Firewall and Router.
I had 2-Cisco 3560 Switch , 2 - Cisco ASA 5520 Fw and 2 - Cisco 2921 router.
Let me explain how the devices are connected. Created HSRP between the Users VLAN in the Core Switch for the Gateway HA.
Also made a Priority set on one of the L3 Switch and make that a Root Bridge.
Configured 2 Firewall with Active/Standy mode and also 2 Routers LAN Interface with HSRP mode for HA.
All the Firewall Outside and Router LAN Interfaces are connected in a L2 VLAN. Also created a Separate L2 VLAN for the Failover link and connected.
Please refer the attached diagram for more clarity.
Now the activity is to create a Site to tunnel in the Firewall to connect other locations.
Problem : Sometimes the Secondary Firewall become as Active Firewall and we are unable to ping anything outside.. but the same ip's are reachable from Standby Firewall. I am suscepting that all the ports are in Secondary switches are in blocked port .. it may be the cause.
I made the Secondary Firewall connectivity to the Primary Switch and start to do the configuration change, but some what in between the default gateway is not getting reachable and tunnel is going down.
*** Some ip's i am able to reach from the Switch-A but the same is not reach from Switch - B and also from the Firewalls. No idea why it is pinginig.
*** Is it a proper setup to connect the devices or we need to do any changes.
Kindly suggest me the right setup and Configuration .... which will provide a HA in all layers.

Hi Ganesan,
I am proposing a design like this. You can have the STP in pvst mode and have a different priority set for the core switch to make it core a as root bridge. There is nothing wrong with your design you have made you core switch which will be physically down to your firewall... but in real it comes on the top of your firewall as well... But spanning tree conf should be done properly to achieve this... I have proposed my design which is pretty simple but easy for troubleshoot....
You can have your firewalls connected to core switch on the down and can directly connected to router on outside... always core a -->py fw--rtra will be the primary path... if anything goes wrong then secondary line will come in to picture....
make sure that your hsrp will have high priority to ur core a vlan conf for the access switches.....
Please do rate for the helpful posts.

Redundancy and Failover setup for 2 MPLS link with 2 different countries

Hi Sir/Madam,
We have 2 MPLS link and both links are active (from COUNTRY A to COUNTRY B) and we also have 2 partners who are located in COUNTRY B with same building but with different offices and each partner will be using each MPLS link. For example, PARTNER A will use the 1st MPLS link and PARTNER B will use the 2nd MPLS link and we want to have a failover setup (please see sample design below). What is the best solution for COUNTRY A and B to have a full redundancy and failover setup/network?
Any recommendation and sample configuration will be a big help for me. Your feedback is highly appreciated.
Thank you in advance.
Best regards,
Marvin

MPLS links, eh. You mean your MPLS facing ports have actual MPLS labels? Or do you mean your WAN links are running across a MPLS network, but the handoff isn't MPLS?

Network Load Balancing and failover for AFP Sharing

Dear all,
Somebody kindly teach me to use round robin DNS to perform the network load balancing, it's success but not the failover.
I have 4 xserve and want to do the load balancing and failover at the same time.
I have read the IP failover document and setup it successfully, but anyone know is it possible to do the IP failover for more than 2 server?
For example, 4 server serving the AFP service at the same time, maybe I have 1 more extra server to do the IP failover for thoese 4 servers.
As I know, IP failover require Firewire as the heartbeat detection. But one xserve only have 2 firewire ports. May I setting up the IP failover only by a ethernet port and an IP address? does it possible to detect and failover to any server after server down has been detected?
I believe load balancer maybe the best solution but its cost is too high.
Thanks any advance!
Karllee

well, u have 2 options here
software load balancing
request comes it foo.com -> ws7u2 hosting foo.com is configured to run as reverse proxy . this server sends any incoming requests to one of the four back end web server 7 handling your incoming request
hardware load balancing (this you need to invest)
request comes to hardware load balancer who responds for foo.com -> sends requests to four ws7 server hosting your application
you could try out how software load balancing works out for you before you invest in hardware load balancing
here is more instruction on configuring ws7 + reverse proxy (software load configuration)
- install ws7 on foo.com
- create a new configuration (choose port 80, disable java

HSRP Vlan Failover

Hi
I have a question that i would like help with please
Core1------------------Link1----------------------Core2
| |
| |
Access Sw---------------Link2---------------Access Sw
If we look at the above setup, Say we have many vlans running on the access switches
The question is if HSRP is running per vlan, if say for vlan 100 is not allowed on link 1 but is allowed on link 2 and that link 2 drops, does HSRP lose visibility of its neighbor on vlan 100 as link2 is the only link allowing vlan100.
The reason im trying to ask this is I have a client who is having issues with hsrp flapping on certain vlans and they have this setup. I was thinking of allowing the vlans on link 1 as its directly cconnected between the 2 cores and is a 10gig link. Currently Link 1 is not allowing all vlans.
Hope this is clear, Thanks

Yes if vlan 100 is allowed on link 2 and not on link 1 and if link 2 goes down then the core switches will lose visibility to each other for vlan 100 and HSRP would be impacted.

What is POP, POP3, and IMAP When I Setup My Email Account in the HP ePrint App?

I have done as much research as I can do in regards to setting up the HP ePrint App Email Accounts. If you do not see your email information listed here, feel free to post it below or contact your internet service provider, phone or email company, or whomever else that might know this. I am certain there are many more that could be added but this is a rather extensive list. I hope you find what you need to finish setting up your email applications.
I have noticed information differs from website to website but as I have learned over time, with domain masking and companies buying out other companies, I just researched all the information I could find and that way if one of the hostnames or ports don’t work, then you can continue to view further into this page to see if that information is the same. At that point, if you can’t find what you need here, I would say you have done all that you can do before contacting the appropriate support team for your email information.
Most of the links are active and the ones listed below should send you directly the pages I pulled this information from but only a few of them were from the actual support sites themselves (Apple support was vague, as well as Microsoft, Macintosh, and commonly used ISPs). Save yourself some time by searching here first. I hope you find what you need in this one-stop-shop and if you get an email address not listed here please post it below and I will add it to this original document.
Lastly, as this information is from forum-based and other unofficial websites, I would like to add that this is a copy/paste/edit-for-easy-reading document I created in my spare time. This is a very long document so I do recommend using the search and find quick keys to search for the email you need but the top part of this has definitions as to what servers, ports, and hostnames are and the basic setup in case you need to know what these options are used for and what they mean.
Below are the most common settings needed to set up most POP3/IMAP Email Clients or Devices:
The following information below can be found at http://www.swestcom.com/Support/q4.htm
“What is POP3?
Post Office Protocol version 3 (POP3) is a standard mail protocol used to receive emails from a remote server to a local email client. POP3 allows you to download email messages on your local computer and read them even when you are offline."
"What is IMAP?
The Internet Message Access Protocol (IMAP) is a mail protocol used for accessing email on a remote web server from a local client. IMAP and POP3 are the two most commonly used Internet mail protocols for retrieving emails. Both protocols are supported by all modern email clients and web servers."
"Main difference between IMAP and POP3:
The POP3 protocol assumes that there is only one client connected to the mailbox. In contrast, the IMAP protocol allows simultaneous access by multiple clients. IMAP is suitable for you if your mailbox is about to be managed by multiple users."
"What is SMTP?
Simple Mail Transfer Protocol (SMTP) is the standard protocol for sending emails across the Internet. SMTP uses TCP port 25 or 2525 and sometimes you can have problems to send your messages in case your ISP has closed port 25 (How to check if port 25 is open?). To determine the SMTP server for a given domain name, the MX (Mail eXchange) should have more information."
"When setting up:
POP - choose POP and the incoming server port will default to 110
IMAP - choose IMAP and the incoming server port will default to 143
All other settings are the same.
Username = [email protected]
Password = the password you set up when you configured your mail box
Incoming Mail Server = mail.yourdomain.com
Outgoing Mail Server= smtp.yourdomain.com
Outgoing Server Requires Authentication (typically found in advanced options or settings)
Do NOT check "Log on Using Secure Password Authentication"
Use the same Username and Password as Incoming or select "Use Same Settings as Incoming"
Outgoing Server Port= 2525 or 587This is subject to change based on the individual preferences of your ISP"
Note - Substitute your actual domain name for "yourdomain.com" and substitute the first part of your email address for "user."
Email Ports
For networks, a port means an endpoint to a logical connection. The port number identifies what type of port it is. Here are the default email ports for:
POP3 - port 110
IMAP - port 143
SMTP - port 25
HTTP - port 80
Secure SMTP (SSMTP) - port 465
Secure IMAP (IMAP4-SSL) - port 585
IMAP4 over SSL (IMAPS) - port 993
Secure POP3 (SSL-POP) - port 995.

Have you ever wished you could use your AOL email account with something else, something more powerful, something more convenient than AOL, something like Outlook, Windows Mail, Outlook Express, or The Bat!? Thanks to the wonders of IMAP, you can.
If you set up your AOL email account in any email client capable of IMAP, you can receive and send messages easily. Even the AOL folders — Spam, Saved, Sent Items and your Trash will be there automatically. Of course, you can also use POP to fetch incoming mail in an uncomplicated fashion.
For instructions on how to assist you with this you can also follow this link: http://email.about.com/od/aoltips/qt/Access_an_AOL_Email_Account_with_any_POP_IMAP_Email_Program.htm

What else do I need to know?
If your e-mail account is the type that requires registration, you must register it the first time you sign in to Outlook Web App. Connecting to your e-mail account through a mobile phone will fail if you haven't registered your account through Outlook Web App. After you sign in to your account, sign out. Then try to connect using your mobile phone. For more information about how to sign in to your account using Outlook Web App, see How to Sign In to Your E-Mail Using a Web Browser. If you have trouble signing in, see FAQs: Sign-in and Password Issues or contact the person who manages your e-mail account.

The following information is according to a forum comment at the bottom of this webpage concerning HOTMAIL and mail server settings:
“As other web based email services, Hotmail is using the HTTP protocol for connecting you to your mailbox. If you want to send and receive Hotmail emails using an email client software, then your software must support Hotmail HTTP access for your email account. Some email clients, such as Outlook Express or Microsoft Outlook, offer builtin support for Hotmail accounts, so you only have to select HTTP when you are asked to select your email account type and select Hotmail as the HTTP Mail Service Provider.”
Mail Server Settings for Hotmail using the Microsoft Outlook Connector
If you are using Microsoft Outlook & the Outlook Connector, you can define your Hotmail account just like any regular POP3 email account:
Hotmail Incoming Mail Server (POP3) - pop3 . live. com  (logon using Secure Password Authentification - SPA, mail server port: 995)
Hotmail Outgoing Mail Server (SMTP) -smtp . live . com (SSL enabled, port 25)
Additional information from this website has not been confirmed or validated as of yet but it does include additional information or perhaps corrected information. If the above steps do not fix the problem with setting up an email account for the HP Apps then read on:
Yahoo! Mail Settings
Yahoo Mail offers standard POP3 access for receiving emails incoming through your Yahoo mailbox, by using your favorite email client software. To setup your email client for working with your Yahoo account, you need to select the POP3 protocol and use the following mail server settings:
Yahoo Incoming Mail Server (POP3) - pop.mail.yahoo.com (port 110)
Yahoo Outgoing Mail Server (SMTP) - smtp.mail.yahoo.com (port 25)
POP Yahoo! Mail Plus email server settings
Yahoo Plus Incoming Mail Server (POP3) - plus.pop.mail.yahoo.com (SSL enabled, port 995)
Yahoo Plus Outgoing Mail Server (SMTP) - plus.smtp.mail.yahoo.com (SSL enabled, port 465, use authentication)
· Google GMail Settings
The Google GMail service offers email client access for retrieving and sending emails through your Gmail account. However, for security reasons, GMail uses POP3 over an SSL connection, so make sure your email client supports encrypted SSL connections.
Google Gmail Incoming Mail Server (POP3) - pop.gmail.com (SSL enabled, port 995)
Outgoing Mail Server - use the SMTP mail server address provided by your local ISP or smtp.gmail.com (SSL enabled, port 465)
MSN Mail Settings
The MSN email service allows you to use the MSN POP3 and SMTP servers to access your MSN mailbox.
MSN Incoming Mail Server (POP3) - pop3.email.msn.com (port 110, using Secure Password Authentication - SPA)
MSN Outgoing Mail Server - smtp.email.msn.com (select "My outgoing server requires authentication")
Lycos Mail Settings
The Lycos Mail Plus service allows you to use POP3 and SMTP servers for accessing your Lycos mailbox.
Lycos Mail Incoming Mail Server (POP3) - pop.mail.lycos.com (port 110)
Outgoing Mail Server - smtp.mail.lycos.com or use your local ISP SMTP mail server
AOL Mail Settings
The AOL email service is a web based system, designed for managing your AOL mailbox via HTTP IMAP access. Unlike Hotmail, you can use any email client to access your AOL mailbox, as long as it supports the IMAP protocol.
AOL Incoming Mail Server (IMAP) - imap.aol.com (port 143)
AOL Outgoing Mail Server - smtp.aol.com or use your local ISP SMTP mail server
Mail.com Mail Settings
The Mail.com email service allows you to use POP3 and SMTP servers for accessing your Mail.com mailbox.

The Netscape e-mail system is web-based, which means you can access their e-mail from any Internet connection. Netscape Internet Service also supports AOL® Communicator, Microsoft® Outlook, Microsoft® Outlook Express, and other POP3 e-mail software. The outgoing mail server needs SSL support, so make sure your email client software supports SSL connections over the SMTP protocol.
Netscape Internet Service Incoming Mail Server (POP3) - pop.3.isp.netscape.com (port 110)
Netscape Internet Service Outgoing Mail Server - smtp.isp.netscape.com (port 25, using a secure SSL connection)

RE: Hard Failures, KeepAlive, and Failover --Follow-up

Hi,
It's a really challenging question. However, what do you want to do after
the network crash? Failover or just stop the service? Should we assume
that when the network is down, and so do your name service?
One idea is to use externalconnection to "listen" to your external non-forte
alarm, so do "whatever" after you receive the alarm instead of letting the
"logical connection" to time out or hang.
Regards,
Peter Sham.

Subject: Hard Failures, KeepAlive, and Failover -- Follow-up
I've gotten a handful of responses to my original post, and the suggested
solutions are all variations on the same theme -- periodically ping remote
nodes/partitions and then react when the node/partition goes down. In
other circumstance this would work, but unless I'm missing something this
solution doesn't solve the problem I'm running into.
Some background...
When a connection is set up between partitions on two different nodes,
Forte is effectively establishing two connections: a "physical
connection"
over TCP/IP between two ports and a "logical connection" between the two
partitions (running on top of the physical connection). Once a connection
is established between two partitions Forte assumes the logical connection
is valid until one of two things happen:
1) The logical connection is broken (by shutting down a partition from
Econsole/Escript, by killing a node manager, by terminating the ftexec,
etc.)
2) Forte detects that the physical connection is broken (via its KeepAlive
functionality).
If a physical connection is broken (via a cut cable or power-off
condition), and Forte has not yet detected the situation (via a KeepAlive
failure), the logical connection is still valid and Forte will still allow
method calls on the remote partition. In effect, Forte thinks the remote
partition is still up and running. In this situation, any method calls
made after the physical connection has been broken will simply hang. No
exceptions are generated and failover does not occur.
However, once a KeepAlive failure is detected all is made right.
Unfortunately, the lowest-bound latency of KeepAlive is greater than one
second, and we need to detect and react to hard failures in the 250-500ms
range. Using technology outside of Forte we are able to detect the hard
failures within the required times, but we haven't been able to get Forte
to react to this "outside" knowledge. Here's why:
Since Forte has not yet detected a KeepAlive failure, the logical
connection to the remote partition is still "valid". Although there are a
number of mechanisms that would allow a logical connection to be broken,
they all assume a valid physical connection -- which, of course, we don't
have!
It appears I'm in a "Catch-22" situation: In order to break a logical
connection between partitions, I need a valid physical connection. But
the
reason I'm trying to break the logical connection in the first place is
that I know (but Forte doesn't yet know) that the physical connection has
been broken.
If anyone knows a way around this Catch-22, please let me know.

Make sure you chose the right format, and as far as partitioning in concerned, you have to select at least one partition, which will be the entire drive.

HP DeskJet 712c Driver and Wireless Print Server Setup

I have recently purchased a MacBook Pro and am unable to setup my printer to print. Previous to using the MacBook Pro I was using a windows machine without any trouble printing to this printer, however now I can't locate the printer on a list of pre-installed drivers for Mac. I've already checked HP's website and was unable to find any drivers that were for Mac OS. What is a good alternative driver source? Once I do get the driver what would my next steps need to be to set up the wireless print server to work with my mac?
Printer: HP DeskJet 712c
Wireless Print Server: D-Link DP-311P
I would be grateful for guidance to go about this process so that I can use my printer again.
MacBook Pro 2.16GHz Mac OS X (10.4.6)

HP-provided drivers don't support network printing. You'll need to install Foomatic (a PPD interpreter), ESP ghostscript (postscript translator) and the 712c PPD from:
http://www.linuxprinting.org/macosx/foomatic/
http://www.linuxprinting.org/showprinter.cgi?recnum=HP-DeskJet712C
Then, since we don't have the auto-setup software for OS X, you need to review the print server manual and find out which IP printing protocol to use. The easiest is HP Jetdirect (called TCP/IP raw port printing in many manuals) if it's available, because it doesn't require the device queue name.
Good luck.

Yes, you can install and use the software on the 2nd machine so long your new company owns the license, the software is used but the same person who is using the primary installation (that is, you).

Failover clusterign... How similar do the primary and failover instance need to be in a failover cluster?

How similar do the primary and failover instance need to be in a failover cluster?
Does the number of database have to match, naming, general config etc...
Mr Shaw

In failover clustering, you use shared storage so the number of databases is irrelevant since only one node can see/access the shared storage at any given point in time. Ideally, the server configuration should be the same on all of the nodes to minimize
potential issues that may impact downtime. However, you need to consider licensing/# of CPU-cores and implementation cost, especially if you are only using the other nodes as standby. As far as licensing is concerned, the standby has to have the same or fewer
number of CPU-cores as the primary node to be covered by licensing. Besides, you don't want your standby node to be more powerful than your primary node. This is why the option to have a hybrid deployment of having a physical server as the primary node and
virtual machine for standby nodes is now supported.

Load balancing and Failover

Hello,
We are wondering how load-balancing and failover of tpcall() work with
WTC:
The scenario:
We have one WLS Domain and two Tuxedo Domains. The Tuxedo Domains offer
the same set of services.
In the bdmconfig.xml, we specify connection_policy as 'ON_STARTUP' for
both Remote Tuxedo Domains. We also Import (T_DM_IMPORT) the same
Tuxedo Service from both Tuxedo Domains.
Questions:
1. Is there any load-balancing of the tpcall between the two Domains? If
so, is it round-robin? If round-robin, what determines the order?
2. If it is ONLY Failover, what determines the order of the tpcall? And,
is the Failover automatic? Or do we need to code for retry on failure?
3. ON_DEMAND vs ON_STARTUP: Does ON_DEMAND drop the connection to the
remote domain upon tpterm? And does ON_STARTUP use a pool of
TuxedoConnection objects?
4. Are there any configuration parameters for
'max_number-of_connections? What determines how many simultaneous
connections can be made?
Thanks,
Suresh Mohan.

Hi Suresh,
The following are my answers to your questions.

The algorithm is random, not RR. Over time this should give equal
opportunities to both remote TDomain.
>
2. If it is ONLY Failover, what determines the order of the tpcall? And,
is the Failover automatic? Or do we need to code for retry on failure?The load balancing is always there. The failover is automatic. When a
connection to a remote TDomain encountered a problem (ie network) the remote
domain will be put on retry open connection (in ON_STARTUP) and the load
balancing will not select it until the connection re-established.
However, the tpcall() that encountered the error will not be retried to send
to different destination. It is up to the application to decide whether it
want to resend. Any requests called after the error will not select the
failed Remote TDomain.

TuxedoConnection objects?TPTERM() only terminate your application session to WTC. WTC still maintain
a secured T-session to remote Tuxedo TDomain. WTC does not use a pool of
TuxedoConnection Objects, the object stored in the JNDI refers to WTC.
>
4. Are there any configuration parameters for
'max_number-of_connections? What determines how many simultaneous
connections can be made?No. As described in #3, there is no need to use connection pool in WTC. WTC
uses session and virtual circuit design concept as Tuxedo TDOMAIN, the
logical pool is created/destroyed dynamically. That is the reason why you
can have a lot of TPACALL() outstanding at the same time. (The limitation is
the availability system resource.)

Load Balancing and Failover with 10G Standard Edition

Hi,
I am new to Oracle Replication and need some help setting up replication for load balancing and failover. Is this possible using Oracle 10G Standard Edition? I plan on having all updates done on the master site and both databases will be for reads. In case of failure of the master site, I would need to be able to failover to the other database.
Also, if anyone knows of any documention for Basic Replication in 10G, please let me know.
Thanks.

Simple nnapshot replication of data would require significant manual effort to configure to load balance or failover. One the load balancing side, you would generally be limited to to static load balancing-- assigning half the users to one machine and the other half of the users to the other machine, regardless of who is actively using the machine. Failover would be a significant manual effort, particularly to bring the failed machine back into the cluster. You would be implementing the guts of multi-master replication.
Frankly, if you actually have a system which is valuable enough to need load balancing and disaster recovery, I'm going to wager that it will be far cheaper even in the short run to buy more boxes and/or enterprise edition licenses than to try to implement this sort of thing yourself. In the long run, it will be far cheaper, since it will be far easier to maintain. Building all this yourself would probably be penny wise and pound foolish.
