My First Junos Switch Detailed Review After Three Days Under The Covers. Background. This post is the story of my first practical look at Junos on Juniper EX series switches.

One day last December, Skeeve Stevens from eintellego opened a can of worms by offering a deal on Juniper equipment to all network engineers on the Aus. NOG mailing list.

Curve 3. 40. 0cl J4. A, was very loud, and the EX2. C was the only affordable, fully managed Gigabit fanless switch which I could find from a major networking vendor. So I ordered one and waited patiently. I expected it to take 6 weeks or so to arrive since apparently all the cool kids ordered one too, so I was pleasantly surprised when it arrived the day after Boxing Day. For those non Commonwealth inhabitants reading this page, Boxing Day is the day after Christmas Day its always a holiday here in Australia. Over the ChristmasNew Year break, I spent three days learning and playing with Junos. I dont claim this as a fair, balanced, or reasonable review its simply a recounting of my experiences. I wanted to get a good general idea of the Junos platform and set it up as my main office switch, moving the HP to my test lab which is only turned on when im using it. So the basic task I set myself was to learn enough Junos to replicate the functions of my Pro.

Comment by jane w on 17 December 2009 Great, thanks for the download I couldnt get Packet Tracer through the old Cisco website. CiscoNET. com is a large collection of IT networking knowledge, tips, configurations and tutorial videos. Troubleshooting portal. Curve as completely as possible. I knew ahead of time that it wasnt going to be a 1. OSPF and PIM DM multicast routing. Junos requires an additional license to implement OSPF, and it wasnt discounted buying it would nearly have tripled the cost of the switch, so I knew that id be eliminating that part of my config. My other OSPF devices are VMs running Debian Linux with Quagga, and Cisco 1. IOS, so I simply connected them to the same VLANs and phased out the Pro. Curve as a router. Hardware. My first few impressions of the hardware were positive The biggest turn off for me on the hardware side was the realisation that Juniper switches use zero based port numbers. Seriously Being an old C programmer, I think of this as proper from a programming perspective, but try telling an end user troubleshooting an issue in a branch office over the phone with tech support that port 1 is the second port not the first. I cant think of any reason other than compatibility with the way theyve always done it on their routing platforms, and I consider this self indulgent behaviour on an equipment manufacturers part. Other vendors manage to start unit or chassis numbers at zero without being bloody minded about starting port numbers at zero although HPs Comware switches start their port numbers at the bottom left rather than the top left, which is almost as frustrating. Software. After my inspection of the hardware, I moved on to plugging it in and inspecting the software. Bootup took a bit longer than I expected the system uses a 1. GHz Marvell ARM CPU the same as in my QNAP TS 2. P, but it looked reassuringly Unixy Junos uses a Free. BSD based management plane. After seeing the switch booted through to a login prompt, I logged in as root and had a poke around. Typical Unix commands like ls, df, and ps all had their usual functions, and one runs cli to get into the Junos configuration system. I worked for the first day or so from the serial console. I noticed some disconcerting dates in the initial copyright notice This product includes Free. BSD software developed by the University of California, Berkeley, 1. Does this mean that 1. Free. BSD project I hope this is not true, and that Juniper are actively engaging with the Open Source project upon which their code is based. Gate. D software copyright 1. Regents of the University.

It has been a very long time since Ive seen a Unix distribution old enough to contain a gated implementation, and I sincerely hope that no vestiges of this code remain. During boot an alarm light appeared on the front panel. I was afraid I had a hardware fault and would have to return my shiny new switch After some investigation in the relevant manuals, I found the command to view the active alarms show chassis alarms and found that it was due to the management interface being down. I already had a management VLAN in my network, and I was expecting this switch to host it. I investigated the management LAN at this point a shout out to the helpful folks in juniper is due and found that it was not VLAN capable at all. Its more like a NIC for the switchs management plane. So its a true out of band network, and cant be bridged onto any part of the data plane. I quickly decided not to use it and disabled the alarm with set chassis alarm management ethernet link down ignore. I can understand why the management port is provided, but id much prefer that it could be bridged in software, if necessary onto the relevant VLAN for installations that arent large enough to have a dedicated physical out of band management network.

Software Updates and Support. When commissioning a new switch, router, server, storage array, etc., one of the first things I do is look for the latest firmwaresoftware to ensure Im up to date with security patches. This proved to be a bit of an issue for Junos. As a newly arrived customer, I didnt know what to expect HP offers all software updates for their switches on their public web and FTP sites with Cisco its a bit more involved, requiring a login to their site, and with routers you need to know the right things to say to TAC if you dont have a support contract with switches theyre more generous could this have anything to do with the existence of GNS3. With Juniper, it seems one must have a login on their site that is specifically granted access to register devices. I had already registered a user account on their site in order to download the documentation and view their certification materials, and I was somewhat perplexed and frustrated to find that I couldnt even register my switch until Juniper had changed my account to have real customer status. Their support staff were first class though, and got it sorted out pretty quickly. Documentation. My reading of documentation began with Junipers Day One guides, some of which I had downloaded prior to receiving the switch. These guides range from the 6. Exploring the Junos CLI to the massive Complete Software Guide for Junos OS for EX Series Ethernet Switches, Release 1. Suffice it to say, I only used the latter as a reference. If youve used Vyatta at all, youll find the former guide a fairly dull read. A quick skim to see the differences between Junos and Vyatta was all that was necessary for me.
