I may need some 10G CWDM SFPs soon. Cisco doesn't make any, does anyone have a brand recommendation? There seem to be a few brands out there and they all look the same to me.

CrazyLittle posted:What are you guys doing for 10gig switches? We're buying Arista 7150's now. I have been really impressed with Arista right now especially with their support. We had a NAT configuration issue and the first person that responded to my support email actually knew what they were talking about. Since Dell acquired Force10, they have been pissing me a lot off lately. The latest fight I am having with them is that they decided to covert the Force10 serial numbers to Dell Service tags. That's great and all, but there is no way to remotely pull the service tag from the switch (it only shows the Force10 serial). Even with the Dell-branded Force10 switches the only way to retrieve the service tag is to look at the sticker on the chassis.  Pricewise, Arista is pretty competitive with Force10 so it's a no brainer for us.

Herv posted:Huh, I'm trying to bring up a GRE tunnel on a 6500 that once had a VPN module, now removed, and getting ISAKMP errors. For what's it worth that's the same debug message you get from a 7600 with no crypto card because it can't do crypto in software. I think the 6500 *should* be able to do it without a card but I'm not sure. I'll try to look into it and see what I can find out tomorrow. That said, I hope you're not expecting any specular (or even mediocre) performance from that thing for crypto. Any chance we can get a full set of debugs (guessing it fails at end of main mode) and a show run | sec isakmp?

I would buy Arista if I were buying, but I'm about to get swallowed by a big Cisco fish and all my dreams of opensystem multi-vendor hippie flowers will shatter just as they'd shimmered into view... everything is really Finisar optics in sleeves, no? edit: seconding service tag nonsense (your databases are my problem  ). One other problem with Dell support: Dell Europe, Asia, Australia and North America all seem to be different companies. That's four vendors sending you invoices, four sales reps to badger when Irish support is dragging rear end, and you'd think that because I have Dell switching, I could get less finger-pointing from Dell Storage or vice-versa. Not really. edit2: also Network Hardware Resale. Not if you need it now, then you go to your serious VAR. Not if you're loving over a channel partner who sells directly to you. But if you need it kinda soon and a bunch of it cheap (maybe smartnet it later  ), they're awesome. Good RMAs, all that. Sales guys love you for buying.

This is something the vendor will handle. The EEPROM in the optic stores the serial number and other identifying information. Good third party optics vendors will reverse engineer this so that the optics appear to be authentic Cisco gear. Then there's no need for service unsupported transceiver/transceiver permit pid all. In the early days of third party optics you'd run into issues where the vendor would assign the same serial number to multiple optics. Turns out that causes bad things (like a card reboot on a 6500).

Currently have a L2 switch acting as a L3 switch. Issue is that it isn't redistributing static routes correctly. We've made a bunch of changes to BGP AD and the like. Tonight I'm replacing the L2 with an actual L3 3560. Under the routing statements for EIGRP, what do I need for a stub to properly advertise both static ranges/ip routes and actual ranges on an interface? It was an either/or situation last time we fooled with it and I assumed that was due to it being a L2 switch only. "Redistribute static"? "EIGRP stub connected" is on the production switch and we thought this may be why our Core's were not loading the static entries correctly. Correct me if I'm wrong, but the stub command would keep the Core's from polling the switch for the routes, correct? Trying to remove that command results in the error: "EIGRP is restricted to stub configurations only on this platform." We tried "eigrp stub static" but it killed all traffic IIRC. I don't think I'll need any as AFAIK no other switch with a similar concept requires any statements like the above. Zuhzuhzombie!! fucked around with this message at 17:12 on Aug 1, 2013 |

A 3560 can do full EIGRP, but from that error message it sounds like you don't have the right code loaded on to that switch. I believe you need IP-services.

Yeha, I'm replacing a L2 3750 that we rigged as a L3 switch in an emergency with a full/licensed L3 3560.

Try eigrp stub connected static(you aren't limited to one of connected/static/summary/receive-only, they are all usable at the same time). Stub will only advertise what it knows about locally, so anything it learns from neighbours won't be advertised. ruro fucked around with this message at 22:26 on Aug 1, 2013 |

Finance NAT = sNAT 4 times over radianz, or sNAT/dNAT twice for VPN/direct connect, or policy NAT because JPMorgan takes weeks to approve an addition to the VPN. That poo poo was the worst. ^^^ Also the Nexus 3548 sucks rear end in a high packet environment, igmp snooping and ntp have some cpu leak bugs that cisco has been trying to figure out for a few months now. Not sure if Arista has the same problem since they share some common hardware edit: I'm thinking of the 3064 with broadcom ASIC's Sepist fucked around with this message at 16:27 on Aug 2, 2013 |

Rofl. That reminds me of when the ISP I used to work for sent out a marketing mailer with how fast our packets traveled in miles per hour. IIRC they literally pinged a server in another state, then took the distance from our city to there and half the round-trip time to come up with a speed. It was glorious.

Man all y'all talking about your super cool datacenter switches is making me jealous. Although to be honest, given the fact that we run 3560s at our edge (supporting 2 or 3 machines in some cases), I'm kind of surprised we don't have Nexuses running in our DC.

Don't feel too bad, the coolest gear I get to work with is a few 2911's, 1921's and a shitload of Fortigate endpoints. And a bunch of linux based value added stuff  YOJB next year. Still, I feel like I deliver cool functionality to our customers on very slow, per kilobyte billed satellite equipment.
