How do you verify a CCIE certificate? Everything I found says to go to here but when I do that while logged into my Cisco account, I see this:

Wow. Cisco broke their CCIE tool. It used to be you'd put the name + their number and it would return yes or no. I guess that was too elegant a solution for this brave new Web Three dot Oh world. You might check here: http://www.cciehof.com/

Just to caution you. That isn't a comprehensive/complete list. Many of the pre-10K CCIEs are missing and if you look you can see several gaps in the numbers etc. AFAIK only Cisco has a "definitive" list.

It's a simple process through the Cisco/Integral Site. We make everyone do it if we are even phone interviewing.

lol internet. posted:Maybe checkout one of their webinars. You get a free AP (Meraki MR12) if you register to the webinar with a business email. Might not use it in the workplace, but it will probably beat any home router wifi. Thanks for this. Guess a co-worker and I are getting free APs and T-shirts sent to us as well as a demo package of the rest of their stuff. Sounds like our company had been courted by Meraki for awhile but since we're an all cisco shop there wasn't much traction until recently

I recently bought a cisco catalyst 2950 switch and a cisco 2600 router to practice for my CCNA exam. I have the switch but not the router, I went ahead and plugged it into into my current network setup at home and am trying to access the ios command line. I don't have a console->usb adapter so I ripped the end off of a short ethernet cord and flipped an end over to make a rollover cable. However, since it hasn't been setup yet it doesn't have a telnet password and I am unable to access it just getting a "Password required, but none set" error. Is there anything I can do about this via rollover cable or am I going to have to get the serial->usb adapter to be able to do my initial configurations? Edit: It looks like I might be able to access the Express Setup via a straight through cable and set a password for the telnet through there assuming the previous owners cleared the memory completely before shipping it to me. Then use my rollover to access it via telnet and go from there to get to the ios command. http://tinyurl.com/bgorsbz jiffypop45 fucked around with this message at 01:59 on Mar 10, 2013 |

You can use another router and connect its AUX port to switch console port (using rollover cable you made). If you don't have a router (yet) then get usb->serial adapter, or motherboard with serial port and cisco console cable.

I was able to use the express setup via a straight through cable plugged into one of the front switch ports after setting the password via the terminal for it. However, since I don't have the router there's not a whole lot I can do with it beyond just using it as a plug and play switch for my already existing network. Router gets here Monday but I'll be on out of pocket for two days on a business trip and won't be able to play with it until Wednesday. Thanks for the help the two of you who answered, having these to play with will certainly make studying a bit more fun.

I'm looking to deploy a fresh environment for a service provider, a managed hosting datacenter with a DR site. Budget-wise, everything should be enterprise/carrier class but not going crazy if it's not necessary (eg: using a ASR1006 over a 1001 just because I want to) They're looking at 10Gb for lan uplinks, but not to the servers. The sites have to be fault tolerant and security is a big concern. Here's an image link of the visio I've drawn up of the production network (Dev/QA will be firewalled off on it's own layer 3 segment), any comments/suggestions on it or the hardware I've listed for the first draft?

What's the advantage of using a nexus over a 6509 in that situation if the network follows a traditional hierarchical design?

Options, really. They said they want to have the best of everything with 10g with redundancy, so I'm giving them the option of Nexus with vPC or the Sup 720 10g with VSS. I haven't played with Nexus yet so I also have some personal agenda in here where I'm pushing more for Nexus

What about the Sup2T which costs the same, is 80gigs per slot, has proper COPP etc.

If the sites need to be fault tolerant, why not double up on the cores and ASAs? Or is that implied?

Read this when you get the chance: http://www.cisco.com/en/US/docs/switches/datacenter/sw/design/vpc_design/vpc_best_practices_design_guide.pdf That's just the design. I've come across a couple of bugs when running L3, some of which minor (ipv6 stuff) and some major (we ended up completely ditching VPC as a concept and going back to one chassis with dual line-cards for everything due to one OSPF bug). Granted this was like, 2 years ago. So I'd expect these problems to be fixed - hence "traditionally" - If I can find the problem in the bug toolkit I'll link it.

Since everything is from scratch, have you consider looking at Juniper? MX5 for ASR1k, SRRX650/SRX1400(?) for ASA, EX8200/9200 core, EX4500 (10gig x 40) dist, 4200/3200/2200 access. Just curious.

So 3850 switches. We're paying to beta test some right now cause we figured they'd be solid enough like the 3750s for a few things. We're probably sending the pair back tomorrow and getting some 3750-X's for a distribution layer at a smaller site. Pieces of poo poo adding massive jitter to the network when we tried to deploy them. Lesson learned, wait a few code trains before buying newer gear

I'm not familiar with Juniper so I hadn't looked at it. The other half of this is that besides designing it, I'm also leading the team that will ultimately implement so I have been sticking with my guns.

Keep in mind that when deploying the Nexus 2k FEX, that they cannot local switch, all traffic, even L2 adjacent ports on the FEX must go up to the 5k then back down to communicate.

Thanks for pointing this out, I got a different response from a Cisco guy at a VAR we're working with... He was suggesting 5k core in building A, with 2k FEXs in building B doing for our racks and storage traffic. Really don't want storage traffic hairpinning, I don't think.

You should forward him this documentation straight from the horses mouth: http://www.cisco.com/en/US/docs/switches/datacenter/nexus2000/sw/configuration/guide/rel_4_0_1a/FEX-overview.html Specifically this portion: http://www.cisco.com/en/US/docs/switches/datacenter/nexus2000/sw/configuration/guide/rel_4_0_1a/FEX-overview.html#wp1197054 quote:The Cisco Nexus 2000 Series Fabric Extender does not perform any local switching. All traffic is sent to the parent switch that provides central forwarding and policy enforcement, including host-to-host communications between two systems connected to the same Fabric Extender

So realistically the 2k Extender is literally just a device to help with cabling and port density I'm taking?

It's an external line card, basically. This is a stupid question but has anyone used the 5k/2k for ToR/EoR iSCSI backup network? This is another requirement I need to add to the visio and I'm thinking I'm just gonna suggest nexus.

Sepist posted:It's an external line card, basically. Besides the obvious "no local switching" I know there are some caveats if you are deploying them as ToR and server teaming. I originally understood it to be that you could not build a server LACP/etherchannel bundle across two different FEX modules, but the following article seems to state otherwise, but it is also dependent on how you deploy the 5k/2k configuration. Not sure if you are looking to deploy with multiple 5k/2k setup though. http://packetpushers.net/cisco-nexus-2000-a-lovehate-relationship/

Not sure how many racks they're going to need as of yet, it's all high level right now. Just had a budget conversation with them, might need to look at global traffic managers for multiple DC L7 load balancing..

You can run Nexus 2ks in a variety of ways. You can plug them into Nexus 5ks or 7ks and you can either connect them to just one upstream switch or two for extra resiliency. They're great when you know your traffic goes "north/south" as opposed to "east/west." I think if I were running storage traffic on them I'd just plug the storage into the 5k/7k directly to avoid that traffic hairpinning. I'm currently running vPC/LACP across multiple 2ks without issue. I like using the FEX's because you can bolt on a shitload of switchports without having to deal with STP or anything funky like Fabricpath. It's like using 40+ slot Nexus 7ks.

Anyone have any tips or a list of "Radio reset codes" for Cisco? I've got an 1141 autonomous AP and the Dot11Radio0 interface keeps going into reset status every few days for seemingly no reason, then I have to reload to get the radio back up. Running firmware 12.4(21a)JA1. Connected to a Cisco POE injector. I see a "Last radio reset code 06" when I do sh controller dot11radio 0
