Re: New Switch Gear / Various GoodiesI've got to say I'm unhappy with the juniper EX 4200's (bought in mid 2010) in the first few weeks they crashed repeatedly, one of the times required loading new software via serial, the last "solution" has been to upgrade to the latest software just to make them stable and yet the web interface and the telnet interface still crash (atleast their main use, ie ethernet switching, has been stable now)
its a sad thing with some crappy netgears out do a $30,000 switch stack. |

I've heard that, we mostly use Cisco and HP for switching fortunately. Some of Juniper's latest issues have me questioning their reliability, like that bad BGP/OS update that brought down Level 3 (» www.truedigitalsecurity. ··· nternet/). It is isn't it? I personally prefer Brocade over Juniper, but alas that's not where the corporate focus is. |

I prefer cisco over juniper but higher ups wanted juniper even though a cisco 3750G (or X which ever was current at the time) would have saved over 1000 per switch and gotten all the same features (poe, dual power supplies(without having to order the 2nd as another line item), 48gig ports, 2 10gig capable ports, ect)
the juniper WXC (wan accelarator actually slows the wan to a crawl so its basicly fully disabled)
the only thing that was good was that it allowed us to get rid of the netgear stack (but other than that no improvment) |

Netgear stack?!? *shudders* I recently ripped 50 netgears out of a customers... In the process of verifying VLAN configs on the existing gear, we were repeatedly forced to click OK to this lovely message. |

I know, but the 3 switch netgear stack (btw I do mean stack they had a stacking cable type link) was far more reliable than the junipers
messing with vlan configs on them was total crap and super easy to forget to hold ctrl and accedently clear a part of the config (so we pretty much didn't use vlans on the netgears) |

Netgear is the devil. We tried to setup one the other night for a buddy and it just would not work to save it's life. I also have one at home in my lab and what a cluster fuck that is. Using the GUI don't bother.. Using the CLI.. Painful. Makes me want to go out and cause gratuitous violence |

Juniper router's I've seen so far have only been slightly less bad the juniper router hasn't crached taking down the office I'm in yet, but it has at another office (weekly) |

That's what I figured. Juniper routers are used on a large scale though (for better or worse) since they have higher throughput that Cisco's equipment, and are cheaper in some cases. |
|
DarkLogixTexan and Proud Premium Member join:2008-10-23 Baytown, TX |
well I'll give them cheaper they sure are built dirt cheap the lack of throughput might be more of higher ups picking a dumb network design (they claim it'll allow them to more easily lock down the network)
ok so the switches are layer3 switches capable of doing great (in theory) intervlan routing right? well forget that the SRX is doing the inter vlan routing
so we're limited on traffic between vlans, all the computers are connected to the switches at gig but so is the router and the router is doing the inter vlan routing, and of course the SRX is also doing the firewall/nat and a vpn to a remote site, so its at fairly high load all the time |

Well the nice thing is that the SRX's can handle it, the Juniper (and Cisco) routers get bogged down with lots of services; NAT and Firewall/IDS especially are killers. |

DarkLogixTexan and Proud Premium Member join:2008-10-23 Baytown, TX |
Previously we had a cisco 1711 that handled it flawlessly, of course that was a flat network so it didn't have any intervlan routing
and atleast due to the topology data from one vlan to another is greatly limited by the srx, and its at near max load 24/7 and the srx is crazy bogged down
luckily not many send large files offten to the fileserver as that will bog the SRX to a crawl and slow all other traffic
really it would be way better if the EX4200's did the inter-vlan routing |

1711...that's a blast from the past. I still have a 1720 floating around somewhere.
That's not surprising, especially if your pushing gigabit to the SRX (depending on the model). The lack of large files helps; we image from the servers so that wouldn't work for us.
It would, which is why the 4506's/3750's handle the inter-vlan routing for most applications. |

Ya, oh well higher ups want the SRX to do intervlan routing
if it were up to me I'd have the 4200EX (ok really I'd have a 3750X) do the intervlan routing
and I'd have nic teaming setup on all the servers, as well as on the ESXi hosts
at home I have a NME-16ES-1G-P doing my intervlan routing and its linked to my 2960G via gig (though if I had a 3750G at home I'd let it take over, or if it didn't have rudundant power I'd get the stackwise etherswitch) (I wish I could justify buying a NME-XD-48ES-2S-P to replace my NME-16ES-1G-P) |

It makes sense rather than taxing the router, but they should migrate it to the switch realistically, since CEF can handle routing much easier than a process-based router.
That isn't set up all ready? I think that nic load balancing is one of the most important things on a mission critical server.
I have it set up a little differently at home. I have a 2811 that does NAT and basic firewall, which feeds a Layer 2 switch. Inter-vlan routing is handled in Hyper-V by Vyatta (previously handled by Nexus 1000V). I don't use my Layer 3 switches for anything other than as a test bed, due to noise and power requirements (not to mention lack of gigabit ports). |

ya we had setup nic load balancing but then just by random occurance at the same time symantec messed up and the nic load balancing was initialy blamed and when symantec was fixed the nic load balancing wasn't put back yet
and with the file/folder redirection (desktop/My documents/ect) being moved to the file server and then synced there are some throughput issues but we'd need to move the intervlan routing and thats just not going to happen
good companies shouldn't offload most of their main office IT work to contractors and then they shouldn't hire the contractors that lead them down a bad path. |

Managers should stick to managing, not dictating. |

Then their jobs would be made redundant if workers could manage themselves. Besides, they lose the fun of micromanaging things then. |

Its the head of one section of IT that made that ruling (our IT is split into a few sections) If I came in and fixed it they'd likely be ticked off so fast those pesky Layer9 issues can be impossible to fix (or atleast fix and stay employed) |
