Cisco released the next generation NCS core router

On November 21st, held a "core router Cisco" next generation conference in China, launched the Tlevel of NCS core router series, the products have been released in September this year. Butas recently in June, Cisco has just released the CRS family of the last product, the 400G corerouter CRS-X. First, Cisco released two - generation products so rapidly, the CRS family three product release interval was 6 years, 3 years.

The release of the NCS family consists of three products, NCS 2000, NCS 4000, NCS 6000,which supports single slot 100G, 400G, 5T capacity, programmability and virtualization support,can help telecom operators to accelerate the transition to SDN/NFV.

The Network Covergence System (NCS) is a set of systems aimed at the service-providernetwork so don 't get all excited about tying it to Insieme, the spin-in that' s developing a hugeswitch (or something) for the data center. Insieme 's launch is still pending, probably untilNovember, it now appears.

The NCS line, being introduced Tuesday, includes a few products:

The NCS 6000 is the aforementioned core router, shipping today with available 1 Tb/s cards(ten 100Gb/s interfaces) and an eventual capacity of 5 Tb/s per slot, Cisco claims. (LightReading broke the story about this system in June, based on a document that called it theCTR.)

The NCS 4000, a smaller box for positions closer to the network edge; it supports 400 Gb/s perslot. This one 's not shipping until the first half of 2014

The NCS 2000, which isn 't a router at all but is part of the optical network (a reconfigurableoptical add-drop multiplexer (ROADM), if you have to know It s shipping today.').

The company said its Network Monitor tool can identify more than 1700 applications for in-depthanalysis by performing deep-packet inspection, and uses a variety of classification methods todetermine the true identity of the application and detect potentially damaging suspicious datatransfers, network usage policy violations and advanced attacks.

Network Monitor also captures full Layer 2 through 7 packet headers and payloads from eachsession for a complete record of network activity, as well as packet metadata with the SmartFlowfeature, which can deliver a real-time data feed to LogRhythm SIEM.

Cisco is using the NCS 6000 and 4000 as the vanguard in the company 's strategy for SDN andNFV in the carrier network. You can think of it as Cisco extending the fabric beyond the datacenter, something that large carriers are interested in seeing, says Ray Mota, an analyst withACG Research.

Cisco is not yet announcing any ready-made applications to run on the nPower X1, nor isitannouncing any programming services to help service providers create

applications.

Cisco 2960-S: Problems of Network Issues with Linux Bonding

Cisco 2960-S: Problems of Network Issues with Linux Bonding

I have an environment that I am having some networking issues with.  Major packet loss and multiple mac addresses on arp replies.  My current thought is that it is related to configuration settings of the bonds and the configuration of the cisco switches.  Possibly an issue with vlans and/or etherchannel.  All of which I am unfamiliar with.

I'm sure you will want more information, but to start, please see the configs here:

The bond configuration was working in active/backup mode on some old dell switches at the old companies' location.

Suggestion:

You're using LACP on the servers, so you need to use LACP on the Cisco switch too.

On the stack master, enter the following configuration...

That will configure an EtherChannel using LACP on ports 1/0/1, 2/0/1, 3/0/1 and 3/0/2.  Substitute the ports numbers with the actual port numbers.

SF300-24P Versus Cisco WS-C2960-24PC-L, How to Solve

Question: Is there a best practice as far as selecting a POE switch for a small office with 14 users? Cisco makes several SMB model available and I am not sure if the WS-C2960-24PC-L is overkilled for my environment. I have one avaya VoIP phone, two APs, and some PCs. I need QoS feature on the switch for the Avaya phone. Thanks.

Answer: Of course the 2960 will give better performance but usually for larger networks. the SMB models were desinged with smaller networks in mind. For example i have 5 SMB switches in my current evironment and we have great throughput on our network. In my previous environment i had over 100 29XX models and it was fine.But in my previous network the SMB models would not have been able to handle it. For a small network the SF300 is perfect and affordable. You should have no issues as far as performance.

Queation about the connection of Cisco WS-C2960S-24TS-S

Question: I am about to purchase a EMC VNXe3150 with dual controllers.  I'd like to have redundant switches.  I was looking at the WS-C2960S-24TS-S which comes with LAN entry lite feature set. 

Will I be able to connect two nic ports from each of 2 hyper-v hosts and two nic ports from each SAN controller to each switch and have 4Gbps connectivity from HOST to SAN using LACP?   Will the switches need to be connected to each other?  Using LACP?

If one switch fails would each server still have 2 Gbps connectivity to the SAN?  Could you provide more detail as to what is involved in the setup?

Answer: With iSCSI you would generally use MPIO rather than LACP etc. In general you don't get all paths in use for a single LUN but if you use multiple LUNs then round robin will assign a 1Gb path to the first LUN (say your E: drive) and a second path to the second LUN (say F:). Dependant on your iSCSI initiator LACP may not be supported. Not sure if the VNXe supports trunking rather than MPIO either.

BTW, it's not a SAN Cisco Switch just because you're running iSCSI over it, it's really just an Ethernet/LAN switch but that's just me being pedantic.

Question about IOS of Cisco C2960S-STACK

Question: Cisco C2960S-STACK with enterprise IOS. I'd like to add 3 more. But this time., I'd like to get the recommended 3 2960X with IP Base IOS. From my understanding, all the switches have to have the same IOS. To keep the cost down, I'd like to get everything with IP Base. I am just wondering if there will be any problem as far as incompatibility.

Answer: When different versions of IOS are detected, the stack member switches will use the stack master's verion of IOS to prevent version mismatch issues.  Just make sure to power on the master switch first and let it get up and running before connecting and powering on the member switches, the stack members will then join the master and use its IOS vesion.

More information refer to http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps6406/white_paper_c11-578928.html , details for Cisco Catalyst 2960-S FlexStack..

Cisco FlexStack stacking for Cisco Catalyst 2960-S Series Switches provides a true stacking solution with all switches in a FlexStack stack acting as a single switching unit. FlexStack provides a unified data plane, and single configuration for a group of stacked Cisco Catalyst 2960-S switches.

Stacking Ethernet switches reduces the network administrator's total cost of ownership. The cost of maintaining the network is decreased because there are fewer devices to manage, and the network uptime is increased with built-in redundancy.
