Re: Junos support for IEEE 1905.1 ?

The ex2200 has no wireless capability so your only option is to connect via ethernet.

 

I don't follow exactly how the three devices are being connected to create the layer 2 loop.  Since you have two devices and the ex switch I assume you will use the bottom example in the Deco doc.  In that format there is a single connection between each pair and no loops.

 

If you create a layer 2 loop topology for some kind of redundancy then you will need to enable some version of spanning tree on the devices to prevent the loop and block the redundant ports until needed during a link failure.

Hi

 

I'm a bit late to respond here, but I think since you cannot put the scheduler-map on the IRB interface or it's units, you need to put it on more phyiscal interfaces. Same as you already did for one:

 

set class-of-service interfaces et-0/0/50 scheduler-map MY-SCHED-MAP
set class-of-service interfaces et-0/0/50 unit * classifiers dscp MY-DSCP

Re: QFX5100 interface is always down

Hi

 

If for each server you have 2 links towards the switch and one is up and another is down then i would suggest to check the following:

1. Compare the cable/optics of the working link with the non working link (for same server).

2. Check the auto neg settings on the qfx5100 and the state on the server.

3. Also check if there is any static bundling of the 2 links on the server side etc

 

Hope this helps

Hi and thanks for your answer.

 

I'll try to make things as clear as I can Smiley Happy

 

In the "Deco M5.jpg" attachment shows a pretty good view of my network setup. The Deco M5 units are capable of choosing between a wired- or wireless connection for backhaul. When using a "dumb" switch this works without any problems because the software in the Deco unit’s handle this "loop" by using standard IEEE 1905.1 protocol. But when using a more "intelligent" switch it looks like the software is not forwarding packets based on IEEE 1905.1 protocol. (See Q4 on this FAQ page: https://www.tp-link.com/us/support/faq/1794/)

 

Hopefully this was a little clarifying but perhaps it could be narrowed down to: does Junos support 1905.1 package forwarding?

Hello:

 

It seems that command is hidden on 18.1R3.3. Have you tried to enter the command without tab. It seems that you need to type it completely. Like this: #delete system phone-home server https://redirect.juniper.net

A piece of information to add here,

 

From the server, I try to run  

dhclient eno1 
# eno1 is the interface linked on the server linked to that switch port

I cleared the statistics on the switch side for that interface

clear interfaces statistics xe-0/0/17

and after few seconds packets are arriving on that interface:

Hi yassine_fadh1, 

 

Yes, the input packets were seen previously as well, and another difference I can think of is the auto-negotation in the configuration you shared.  Could you try disabling the auto-negotiation on the xe-0/0/19 interface on which this is not working and confirm ?  Command: 

 

# delete interfaces xe-0/0/19 ether-options auto-negotiation
# commit and-quit

 

 

 

show interfaces xe-0/0/19 extensive    
Physical interface: xe-0/0/19, Enabled, Physical link is Up
..  MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow control: Disabled, Auto-negotiation: Enabled, Remote fault: Offline, Media type: Copper

show interfaces xe-0/0/20 extensive    
Physical interface: xe-0/0/20, Enabled, Physical link is Up
..  MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow control: Disabled, Auto-negotiation: Disabled, Remote fault: Offline, Media type: Copper


Hope this helps. Smiley Happy

yeah the default config is auto-negotiation disabled just for the sake of test I enabled it for a while. Below is the confirmation of disabling the auto-negotiation:

mtu 1500;
ether-options {
    no-auto-negotiation;
}
unit 0 {
    family ethernet-switching {
        interface-mode access;
        vlan {
            members Storage;
        }
        filter {
            input storage-dst;
        }
    }
}

but still not working Smiley Sad

And if you unplug a server's 'up' interface does its 'down' interface come up? It sounds like simple active/passive server-side interface bonding.

Hello Thethakuri,

 

I have seen this issue before and was fixed removing the jphone-home package.

 

Try this command and let me know if it works.

 

request system software delete jphone-home

 

 

Regards,

 

Randall.

In the switch that had phone-home issue, I was able to get rid of that but when I login to J-Web, it right away says the "Your Session has expired." I tried Firefox and Chrome and same issue, it just boots me out.

In the switch with too many redirect issue, don't seem to have jphone-home package

It worked to get rid of phone-home in the other switch.

But in the switch with too-many-redirect issue, it doesn't allow tab or space after phone-home. If I copy and paste, this is what I get

 

root@SW-RCP-CORE-E01# delete system phone-homeserverhttps://redirect.juniper.net

Hi all,

any idea about what is advantage or disadvantage of the BiDi SFP when compering other 10G SFP that for 80km?

Re: distance on optic

BiDi optics use a single fiber to connect between devices while standard optics require two fibers.  Note this means that with BiDi the transmit and recieve run on the same fiber so they have two frequencies noted.

 

I'll also note here that SM optics come in a wide range of distences and frequencies you do need to read the specs on each and match the pairs on the link.  Distances can range from 10-100 km (120 for xfp).  You will need to match both distance and frequency on the link.

 

Also using vastly larger distance rating than needed can cause the link not to work.  There is a hot alarm on optics if they recieve too much power and the link won't come up.  So you would then need to pad the link in that case.  The distance number is a substitute for the transmit power and these are just estimates, your milage may vary based on quality of fiber, splices, connectors and patch panel usage.

Hello 

 

I am assuming that the core switch is not another EX2300, can you tell what platform and Junos version it is running. Instead of copy and paste have you tried to type the entire command?

 

On the EX2300 have you solved the issue with the "session expired". I suggest to check Jweb version. If switch has 18.1R3.3 J-Web version should be 18.1A2. 

 

If an upgrade is required download package and copy to /var/tmp and then run the command for the upgrade " > request system software add /var/tmp/jweb-ex-app-x86-32-18.1A2.tgz"

 

Regards

EX4600 warranty and SFPs

Hello all,

 Hope All is well, I need to assure from the below if any one could help.

- Does EX 4600 come with no ports , in other words ( 48 port  empty ) we shall order separaetly the SFPs which required ?

- Does any Juniper switch come by default with a life time warranty without purchasing its SVC ( Support) or the warranty only  included in its support ?

 

Thanks ..

Just got a few 4600's myself...

 

Yes, all the ports are empty. You will need to buy additional SFPs to match the cabling that you want to run (eg DAC cables, SFM, MMF, RJ45, whatever).

 

I'm not aware of any lifetime warranty switches. They're rare for any vendor.

You will get hardware warranty without a support contract, but the support contract is required for troubleshooting beyond hardware faults.
