YOU’RE INVITED TO

CHANGE THE RULES OF NETWORKING

WITH DATANET AND HP

GETTING TO THE CLOUD QUICKER!

A luncheon for IT professionals to explore
how Software Defined Networking can help
simplify, scale and automate your network.

Software Defined Networking is an approach to networking
in which control is decoupled from hardware and
given to a software application called a controller. In a
software-defined network, a network administrator can
shape traffic from a centralized control console without
having to touch individual switches. The administrator
can change any network switch’s rules when necessary
-- prioritizing, de-prioritizing or even blocking specific
types of packets with a very granular level of control. This
is especially helpful in a cloud computing multi-tenant
architecture because it allows the administrator to manage
traffic loads in a flexible more efficient manner. Essentially,
this allows the administrator to use less expensive,
commodity switches and have more control over network
traffic flow than ever before.

Setting up Authentication on @comware 7

One of the biggest changes to Comware 7 is the role based users. You can define different user roles and change what each role has access to from a command perspective. I strongly recommend reading the following guide:

http://bizsupport1.austin.hp.com/bc/docs/support/SupportManual/c03189486/c03189486.pdf

Below is the “bare bones” info you need to know to get up and running quickly. For some of you this will not be anything new. For others, who have not had the experience with the changes in comware 7 this might help.

For the most part setting up telnet/ssh with local authentication is very similar. You need to enable ssh or telnet server. You need to create RSA public key(for ssh) and specify a local user.

To configure the switch log in through the console port and enter into the system-view.

Configuration procedure

Prior to configuring switch access, determine whether telnet or ssh is required. Then only enable the corresponding server

# Enable telnet or ssh servers

<Switch> system-view

[Switch] telnet server enable

[Switch] ssh server enable

If you are using ssh then create the public key

# Create a public key

[Switch] public-key local create rsa

The range of public key size is (512 ~ 2048).

NOTES: If the key modulus is greater than 512,

It will take a few minutes.

Press CTRL+C to abort.

Input the bits of the modulus[default = 1024](enter)

Gaining access

Logging in through the console port

By default, you can log in to a device through the console port. The

authentication mode is none (no username or password required), and

the user role is network-admin.

Logging in through Telnet

By default, you cannot log in to a device through Telnet. To log in

through Telnet, first log in to the device through the console port and

complete the following configuration:

1. Enable the Telnet function if necessary. (Telnet is enabled by

default.)

2. Assign an IP address to a VLAN interface or the management

Ethernet interface, and make sure that your device and the Telnet

client can reach each other. (By default, the device does not have an

IP address.)

3. Configure a password for password authentication, or change

authentication mode for VTY users and configure related

parameters. (By default, the authentication mode is password for

VTY users.)

4. Configure the user role for VTY users (network-operator by default).

Logging in through SSH

By default, you cannot log in to a device through SSH. To log in through

SSH, first log in to the device through the console port, and then

complete the following configuration:

1. Enable the SSH function and configure SSH attributes. (SSH is

disabled by default.)

2. Assign an IP address to a VLAN interface or the management

Ethernet interface, and make sure that your device and the SSH

client can reach each other (by default, your device does not have

an IP address).

3. Configure the authentication mode of VTY users as scheme (default

is password).

4. Configure the user role for VTY users (network-operator by default).

Checking #Security #Compliance of your #networking equipment with @hp #imc

Keep in mind for those of you that own HP's IMC: IMC does have a compliance center function built into it that can check, notify and provide corrective action on configuration errors and policy verifcation. For example it could be used to determine if the correct snmp switch hardening configuration was implemented.

For reference on how to implement check out the great imc video on you tube that covers this very topic and gives a reference case on how to detect and mitigate incorrect snmp strings.

@hp a-series @cisco command aliases

So..you just cant unlearn all of those cisco cli commands like show or write. Honestly..it is hard jumping on different boxes... even though the industry has adopted pretty much a common cli (except juniper) there are differences. One nice thing you can do on the HP a-series boxes is do command aliases. Type a word and it issues a command. Here are a bunch that some folks like to put on so they dont flub with a cisco command on a hp switch:

command-alias enable

command-alias mapping undo no

command-alias mapping reboot reload

command-alias mapping header banner

command-alias mapping reset clear

command-alias mapping acl access-list

command-alias mapping port switchport

command-alias mapping stp spanning-tree

command-alias mapping snmp-agent snmp-server

command-alias mapping user-interface line

command-alias mapping display show

command-alias mapping undo no

command-alias mapping return end

command-alias mapping quit exit

command-alias mapping sysname hostname

@cisco is wavering on SDN like a us politician!!!

Which way is it Cisco? You dont see value in SDN?

http://www.wired.com/wiredenterprise/2012/10/cisco-vcider/

oh wait... you just bought an SDN company....

www.vcider.com

Who's interest are you working in? yours? or your customers? Its really hard to tell because you appear to be trying to move sentiment by first downplaying SDN, then embracing it. SDN has been building for five years...and where have they been?

@cisco says @vmware is becoming a competitor

http://www.crn.com/news/networking/240007716/lloyd-vmwares-nicira-deal-a-competitive-threat-to-cisco.htm?cid=rssFeed

So..as this plays out.. where does it put VCE? For that matter...as Cisco looks to replace lost revenue... do they add storage and thus compete with netapp and EMC?

The whole partnership they have with these companies just doesnt make sense.

This is where HP can shine..with a complete server, storage, network solution that is integrated and adds value.

@hp adds #irf to #bladesystem

with the new 6125 series of switches that run comware.

Up to 10 in a cluster!

http://h18004.www1.hp.com/products/blades/components/ethernet/6125G-XG/index.html

@hp releases new switches for the #bladesystem

The new 6125 switch family is out and is very exciting because it brings the same Comware operating system that we have in the 12500, 10500, 5900, 5800, 5500, 5120 swtiches down into the Bladesystem.

It also bring innovative features like Intelligent Resilient Framework (IRF) to allow you to cluster up to TEN 6125s together.

Reason #362 to buy @HPN instead of @cisco

Software licensing for the Cisco Nexus is so complex, they actually publish a 20 page guide just to understand it!

http://www.cisco.com/en/US/docs/switches/datacenter/sw/nx-os/licensing/guide/b_Cisco_NX-OS_Licensing_Guide.pdf

Want a routing protocols? You need a license (even eigrp)

Want some like HP's EVI You need a license (OTV)

Want something like HP Multi-tenant Device Context? You need a license (VDC)

Want MPLS? you need a license.

With HP..all of this is included and you dont need licenses!!!

@hpnetworking grew at 6% while @cisco only grew at 4% this last quarter!

#epiphany of the day; #sdn and #openflow are like #atm #svc

I know..I'm dating my self. ATM SVC? LOL. That was a techno flop. But... it was a great idea. Create a network that was based on switched point to point circuits. A server and a user could be on a point to point connection with eachother. What today we would call a link-local connection. It really simplifies the world.
The problem with ATM SVC was we weren't that good at network operating systems yet..and ASIC/CPU designs werent powerful enough to handle the speed and number of setup/teardown requests .

SDNs... and specifically Openflow can make this happen. We now will have a SVC like fabric...but built on ethernet. Techno flashback time... LANE was the solution for ATM.. This is better...no SAR process. Just straight ethernet..nice and efficient. No changes in technologies. You can now trick devices into thinking they are on a very very small network. One link-local to the exchange server... another to the lync server... maybe another to a nas server... maybe another to the internet firewall.

I've got thoughts on how this improves security and broadcasts as well. more about that in another blog post.

#rumor of the day#2: @cisco to divest itself of #UCS

Its a money loser alright. While they've gained some marketshare...it cost a lot of r&d and sales dollars...and...they lost a ton of business to HP and others while they were distracted.

rumor of the day #1: @cisco to get rid of @linksys consumer products

Is #sdn slipping away from @cisco ? @vmware buys @nicira

http://online.wsj.com/article/BT-CO-20120723-713968.html

“VMware said it will acquire Nicira for $1.05 billion in cash and about $210 million of assumed unvested equity awards. The company said the acquisition, which is expected to close in the second half of the year, will position VMware to be the industry leader in software-defined networking.”

@cisco ditches #waas and apparently gets out of wan optimization

@larrysinger from #hp talks about open networking @internet2

#rdma over ethernet #roce

A stronger converged solution than fcoe?

Watch this internet2 talk:

http://events.internet2.edu/2012/jt-stanford/agenda.cfm?go=session&id=10002408&event=1232

RoCE stands for RDMA over Converged Ethernet. Pronounced "Rocky"

@dnssec and amount of sites deployed

public network management?

Is there going to be a trend in allowing anyone to see data about your network? Folks like ESNet are actually allowing guests to view most of the data about their network

https://my.es.net

Interesting internet data out of the @stanford #pinger project

You can see their whole project here:

http://www-iepm.slac.stanford.edu/pinger/

but, I was impressed with seeing the data on the google explorer tool:

And HP gains 2.4%!!!

http://h30507.www3.hp.com/t5/HP-Networking/New-report-by-the-Dell-Oro-Group-HP-Networking-gaining-share-in/ba-p/117139

@cisco lost 4.3% points of wlan market share this last quarter

@cisco lost 1.2% points of router market share this last quarter

@cisco lost 2.8% points of market share this last quarter in #switching

And HP gained 2.4% of those points!!!!

#HP #IMC Service Health Monitor

New #hp #imc module... Application Performance Module rocks!

HP just added a new purchasable module to IMC... Application Performance Module... it allows you to dive in an trend/track application specific parameters on devices. Simple things like if port 8080 is open..or slightly more specific like Active Directory. Here's a few screens shots

@cisco yet again...a follower..this time in #sdn

Well..by now you know my bent...so why even read the post? Well... there is a point...have some patience...

Cisco just released their strategy for SDNs. You can read up many places...check out Light Reading's article:

http://www.lightreading.com/document.asp?doc_id=221921&f_src=lrdailynewsletter

Cisco has always been a follower... it started out with multi-processor routers (wellfleet was first) and then went to switches (kalpana, grand junction, synoptics, cabletron, etc) and many other product lines.

You might argue, so what...they were not a leader in switching and then became one. While true...there are other factors and I'd suggest that the forces that put Cisco together arent there today. The market has changed and from talking to the VCs I know... for the last years, hardware has been out of vogue. Software is in. Why? Huge returns. And why is that important.. money is going to dump into the market and in a big way to develop network architectures based on just software to build the overlays. I could launch a SDN startup today probably with just $600k or so and quickly build a solution. You could never do that with hardware solution...I'd need $30-60M. (on the low side) So... expect to see a lot of interesting innovation.

I'm also skeptical about Cisco and how they are attacking this. First off..they broke with how they always have launched these efforts... the infamous five phase product launch that mysteriously is always launched in phase 2... giving the illusion they had been planning this all along. I think Cisco has the jitters and is not acting rashly.

Lastly... an API? Really? Not to say that HP is not bringing out APIs, we are. But..they have their place. They are for customers that deeply need to control their network...typically service providers and ultra large scale data centers. The bulk of the market doesnt want this..nor needs...nor could even take advantage of it. They want a controller based solution and orchestration software that allows them to drag and drop deploy networks, applications,and security. They want speed... they want to deploy with more control with less staff. This is fail for Cisco.

While I get why Cisco is going the API route... if they convince customers...those customers are locked into Cisco. Its yet another EIGRP, RPVST, CDP, VTP, SCCP, etc in their back pocket...its not the way the market wants to head. They want better control..and they want commodization of the market.

HP0-Y27: DEPLOYING #HP ENTERPRISE WIRELESS NETWORKS exam prep guide

#DLDP is HP's feature set similiar to #UDLD

Sometimes, unidirectional links may appear in networks. On a unidirectional link, one end can receive packets from the other end but the other end cannot. Unidirectional links result in problems such as loops in an STP-enabled network.

The Device Link Detection Protocol (DLDP) can detect the link status of a fiber cable or twisted pair. On detecting a unidirectional link, DLDP can shut down the related port automatically or prompt users to take measures as configured to avoid network problems.As a data link layer protocol, DLDP cooperates with physical layer protocols to monitor the link status of a switch. The auto-negotiation mechanism provided by physical layer protocols detects physical signals and faults. DLDP, however, performs operations such as identifying peer switches, detecting unidirectional links, and shutting down unreachable ports. The cooperation of physical layer protocols and DLDP ensures that physical/logical unidirectional links be detected and shut down. For a link with the switches on the both sides of it operating properly, DLDP checks whether the cable is connected correctly and whether packets can be exchanged between the two switches. This is beyond the capability of the auto-negotiation mechanism at the physical layer.

DLDP can operate in two modes: normal mode and enhanced mode, as described below.

l In normal DLDP mode, when an entry timer expires, the switch removes the corresponding neighbor entry and sends an Advertisement packet with RSY tag.

l In enhanced DLDP mode, when an entry timer expires, the Enhanced timer is triggered and the switch sends up to eight Probe packets at a frequency of one packet per second to test the neighbor. If no Echo packet is received from the neighbor when the Echo timer expires, the switch transits to the Disable state.

Configuration procedure

1) Configuration on Device A

# Enable DLDP on GigabitEthernet2/0/1 and GigabitEthernet 2/0/2 separately.

<DeviceA> system-view

[DeviceA] interface gigabitethernet 2/0/1

[DeviceA-GigabitEthernet2/0/1] dldp enable

[DeviceA-GigabitEthernet2/0/1] quit

[DeviceA] interface gigabitethernet 2/0/2

[DeviceA-GigabitEthernet2/0/2] dldp enable

[DeviceA-GigabitEthernet2/0/2] quit

# Set the interval for sending Advertisement packets to 6 seconds.

[DeviceA] dldp interval 6

# Set the DelayDown timer to 2 seconds.

[DeviceA] dldp delaydown-timer 2

# Set the DLDP mode as enhanced mode.

[DeviceA] dldp work-mode enhance

# Set the port shutdown mode as auto mode.

[DeviceA] dldp unidirectional-shutdown auto

# Enable DLDP globally.

[DeviceA] dldp enable

2) Configuration on Device B

Configure Device B as you configure Device A.

3) Verifying the configurations

You can use the display dldp command to display the DLDP configuration information on ports.

# Display the DLDP configuration information on all the DLDP-enabled ports of Device A.

[DeviceA] display dldp

DLDP global status : enable

 DLDP interval : 6s

 DLDP work-mode : enhance

 DLDP authentication-mode : none

 DLDP unidirectional-shutdown : auto

 DLDP delaydown-timer : 2s

 The number of enabled ports is 2.

Interface GigabitEthernet2/0/1

 DLDP port state : disable

 DLDP link state : down

 The neighbor number of the port is 0.

Interface GigabitEthernet2/0/2

 DLDP port state : disable

 DLDP link state : down

 The neighbor number of the port is 0.

The output information indicates that both GigabitEthernet2/0/1 and GigabitEthernet2/0/2 are in Disable state and the links are down, which means unidirectional links are detected and the two ports are thus shut down.

Correct the fiber connections after detecting the problem, and perform the following operations:

# Reset DLDP state for the ports shut down by DLDP.

[DeviceA] dldp reset
