Seems like the SUP 720-3B is crashed, I will open a TAC case and see what the issue is. I know Cisco TAC team is quite helpful and they will come out with a solution for this problem. If anyone has any inputs or solutions they are welcome provide solutions in the comment area of this post.
Configuring HRSP in a Cisco Nexus 7000 Series Switch is often an easy task and it takes slight different approach. Recently we had some issues in our Data Centre and then I was forced to configuring the HSRP between a Cisco Nexus 7010 Switch and Cisco Catalyst 6506 E Switch. The configuration was quite simple, I would like to share the steps need to configure HSRP between a Cisco Nexus 7000 Series and Cisco Catalyst 6500 Series Switches.
In the below example I will configure HRSP for VLAN 34 with a subnet of 10.204.34.0/24
Cisco Catalyst 6500 Series Switch Configuration
Step 1 – Create VLAN 34 in Cisco Catalyst Switch and assign an IP Address
MBGF-DAC-6500-BB01(config)#interface vlan 34
MBGF-DAC-6500-BB01(config-if)#ip address 10.204.34.3 255.255.255.0
Step 2 – Configure HSRP group id, priority and timers, my active switch will be Cisco 6500 Switch due to its priority
MBGF-DAC-6500-BB01(config-if)# standby 34 ip 10.204.34.1
MBGF-DAC-6500-BB01(config-if)# standby 34 timers 1 3
MBGF-DAC-6500-BB01(config-if)# standby 34 priority 150
MBGF-DAC-6500-BB01(config-if)# standby 34 preempt
Cisco Nexus 7000 Series Switch Configuration
Step 1 – Create VLAN 34 in Cisco Nexus Switch and assign an IP Address
VDC-Admin-AG01-MB-1256-002(config)# interface vlan 34
VDC-Admin-AG01-MB-1256-002(config-if)# ip address 10.204.34.2/24
Step 2 – Configure HSRP group id, priority and timers , Nexus will be in standby mode
VDC-Admin-AG01-MB-1256-002(config-if-hsrp)# priority 110
VDC-Admin-AG01-MB-1256-002(config-if-hsrp)# timers 1 3
VDC-Admin-AG01-MB-1256-002(config-if-hsrp)# ip 10.204.34.1
Verify the HSRP States
Cisco Catalyst 6500 Switch Status
MBGF-DAC-6500-BB01:1#sho standby brief
P indicates configured to preempt.

Configuring HRSP is a quite a simple and if you are facing any problems configuring you can post your scenario in the comments area of this post.
Cisco CEO John Chambers expects Q4 sales growth will be between 0% to 2 %, which is much below the analyst expectations of 7%. Cisco Systems also warned they are looking to reduce the workforce with a target of saving S1 billion per year. Most of job cuts are most likely to come through an early retirement programs, already Cisco managed to shed 550 jobs with the closure of its Flip unit.
During a May 11 conference call to discuss quarterly financial numbers, both Cisco Chairman and CEO John Chambers and COO Gary Moore said job cuts were on the way as the networking giant tries to get back on solid footing after several disappointing quarters.
For the last quarter which ended 30th April, Cisco reported sales were up 4.8% to $10.9 billion, although income was down 17.6% to $1.8bn from $2.2bn in the same period of 2010.
“This quarter played out as we expected,” said Chambers. “We have acknowledged our challenges. We know what we have to do. We have a clear game plan, and we are a company with a track record of market-shaping innovation.”
I expect Cisco to concentrate on their core technologies and products which are quite popular worldwide; especially in Middle East Cisco is a networking pioneer.
At least in this part of World counterfeiting printer cartridges has become a common activity. To tackle this issue HP becomes the first company in the world to debut Toner Cartridge Authentication software. The goal of the software is to detect counterfeit toner cartridges and alert the user that the cartridge is not an original HP brand cartridge
The newly announced Toner Cartridge Authentication software is comprised of three components working together. The smart chip technology contains authentication information which is collected by the Authentication software and transmitted to the authentication web service. That service then checks the data and once it is validated, it is sent back to the software, which shows the result in a pop-up box on a users’ screen. Guess what the whole process takes about a minute, amazing!
The software can be downloaded from HP for LaserJet printers, Inkjet printers already have the software embedded within the firmware. Currently the 1000, 2000 and 3000 series LaserJet printers are supported and by 2012 HP hoping support all the HP products that comes under the ink segment.
“Either you get a message saying no risk detected, all packages are original or you get a big, bold risk detected message. If you get the risk detected message, we suggest you also click the link directly to the anti-counterfeit page,” said Andrea Gebhard, LaserJet Supplies, Imaging and Printing Group, Middle East, Mediterranean and Africa.
According to HP in the span of four years they discovered more than 30 million counterfeit products worldwide.
In addition to the Cartridge Authentication Software, HP advises that there are three basic steps that every user of HP supplies can take to identify the authenticity of an HP product, including checking for holographic security labels on the packaging tabs, checking the quality of the packaging and checking the quality and finish of the cartridge itself.
When it comes to modifying Access lists in Cisco IOS devices most of us remove the ACL’s from the Cisco Router and then edit the entries in a note, and then paste back the modified ACL to the respective router via CLI.
There is a way to reduce the overhead involved in modifying ACL by using the Cisco IOS feature of resequencing.
In the following example in a Cisco router there is an access-list name ITKE
ASW2-02#sho access-lists ITKE
Extended IP access list ITKE
1 permit ip host 192.168.1.1 host 10.1.0.1
2 permit ip host 192.168.1.2 host 10.1.0.2
From the example if we need to add one more deny statement for the host 192.168.1, it’s not possible to add a statement without deleting the current access list and create a new one. But the power of resequence allows you to assign a new set of sequence numbers to current access list as demonstrated below using the IOS command “ip access-list resequence”
ASW2-02(config)#ip access-list resequence ITKE ?
<1-2147483647> Starting Sequence Number
ASW2-02(config)#ip access-list resequence ITKE 10 10
This starts the first entry with a sequence number of 10 and increments all new lines by 10. The result is as shown below
ASW2-02#sho ip access-lists ITKE
Extended IP access list ITKE
10 permit ip host 192.168.1.1 host 10.1.0.1
20 permit ip host 192.168.1.2 host 10.1.0.2
By resequencing the ACL now it’s easy to inserts a new ACL with a sequence number of 15 which would fall between the existing entries in the ITKE access list.

Sony Play Station Network went down one more security beach, according to Sony Official PlayStation blog there is no evidence for stolen credit card detail but Sony even not ruling out the possibility.
“While there is no evidence at this time that credit card data was taken, we cannot rule out the possibility. If you have provided your credit card data through PlayStation Network or Qriocity, out of an abundance of caution we are advising you that your credit card number [excluding security code] and expiration date may have been obtained. For your security, we encourage you to be especially aware of email, telephone, and postal mail scams that ask for personal or sensitive information. Sony will not contact you in any way, including by email, asking for your credit card number, social security number or other personally identifiable information,” said Patric Seybold in the blog post.
I would suggest all PlayStation users to be careful and be vigilant until Sony comes out clean. Make sure to review your account statements and monitor your credit reports daily.
Sony is currently working hard to restore the PlayStation network and hired a recognized security firm to conduct a thorough investigation into what happened.
In 2009 Cisco acquired Pure Digital Technologies was not the brave move, eventually it led to back away from the consumer market by the closure of Flip as part of restructuring. Cisco is expected to reduce its headcount by 550 workers.
May be a better idea for Cisco Systems to concentrate on its core business, especially when there is a rising competition from its rival Juniper Networks and Huawei. I am seeing Huawei gradually making its strong presence in the Middle East market.
According Analysts Flip flopped due to its lack of Internet connectivity, and the proliferation of high end smartphones.
“We have disappointed our investors and we have confused our employees. Bottom line, we have lost some of the credibility that is foundational to Cisco’s success – and we must earn it back. Our market is in transition, and our company is in transition. And the time is right to define this transition for ourselves and our industry. I understand this. It’s time for focus.” said John Chambers CEO of Cisco Systems.
I am looking forward to see how Umi home telepresence going to perform.
