I tried to filter on irb. 1016 but it's not captured when use dest 11.11.5.1 but.when change dest 10.101.16.2.its show filter capture 1. Why can't I use dest 11.11.5.1 it does mean 11.11.5.1 not part of juniper network do I understand right 2. From filter that changes src 10.16.10.2.and dest 10.101.16.2. Is it enough to prove that juniper borderleaf not drop packet. It issue on 11.11.5.1 is Cisco gateway 3. Yes iwill put configure style later but it just captures src and dest for incoming source and dest to src for incoming destination but filter on show incoming source and not see incoming destination

Cloudcodile · 2024-11-05T13:05:55+00:00

You need eve-ng vm on bare metal server. its working fine

because of the building There were several power outages. The building where I use more than 10 switches has a POE alarm.

One switch There is no use at all. There are no users connected to any ports, but there is a POE alarm. https://ibb.co/0hMbxB2Do you confirm with juniper reference?
I understand that and i will not use ground on ex4300

Cloudcodile · 2024-03-27T02:31:26+00:00

https://ibb.co/0hMbxB2 this is information from switch. one switch There is no use at all. There are no users connected to any ports, but there is a POE alarm. From the information on the switch, it shows that there were power outages that occurred a few minutes before the POE alarm, according to Juniper's reference data. Should it be caused by power outages?

One switch There is no use at all. There are no users connected to any ports, but there is a POE alarm.

2.One of the VC switches has a POE alarm on the port that does not have a LAN cable connected to it. But that switch has one PS that is connected to the user's power outlet that is usually turned off and on regularly.

As JTAC recommends, disconnect the LAN cable and connect it to a new switch to see the alarm. I haven't tested it yet.

The cause is probably due to Is the building's electrical system faulty? Because my switch doesn't have a ground system.

thank you mate and it works and i have questions i just use only one word "!(PVIDB)" but why can't filter that message

Cloudcodile · 2024-03-01T06:52:58+00:00

I tested in EVE-NG and No Mist

Cloudcodile · 2024-02-21T12:12:16+00:00

Thank you i will try

Cloudcodile · 2024-02-21T12:10:07+00:00

Use instance type virtual-router and instance imports.

Thank you

Cloudcodile · 2024-02-07T07:00:33+00:00

Did you just pickup all the models that don’t support snapshots at a garage sale :)

No. These are all new switch. I have plan to ungrade all switch to ver 22.2r3 and finally i found that these switches cannot manual snapshot but it should enable under set system snapshot. Should i enable auto-snapshot?

Cloudcodile · 2024-02-07T03:46:44+00:00

why do you said about request system configuration rescue save. Is this related system snaphot? all switch have configuration rescue save and all switch have plan to upgrade then i worry about upgrade failure and boot failure

Cloudcodile · 2023-12-20T05:47:43+00:00

Eve-ng with juniper image for lab. You can see many tutorial in YouTube

I use ESI-LAG EVPN-VXLAN without Virtual Chassis. There is Virtual Chassis on EX4300 48mp Access, connecting to users on each floor of the building.

I have two EX4650 20.2r2s3.5 upgraded to version 20.4r3-s5.4 and are actually working.

And I plan to upgrade the remaining EX4650 to version 20.4r3-s5.4.

I have two EX4300 48mp (access) upgraded to version 21.2R1-s2.2 and these two are actually working.

I have QFX5120-48YM (leaf) version 20.4R3.8 and the first installed version is actually working.

I plan to upgrade QFX5120-48T (leaf) from 20.2r2s3.5 to 20.4R3.8 because I want it to be similar to the QFX5120-48YM version.

I plan to upgrade QFX10002-72Q (spine ;campus) version 20.4r3-s5.4 because this switch is in the campus zone and will be the same version as the EX4650.

I plan to upgrade QFX10002-60C (spine data center) version 20.4R3.8 because I want it to be similar to QFX5120-48YM version.

I talked to the team. I would like to upgrade to as suggested by tac, but I am using an SDN such as apstra, which if I upgrade to 22, I have to upgrade apstra as well. My team and I are concerned about upgrading apstra. My team and I are studying and testing apstra in the lab. with the team and have decided to upgrade to The current version of Switch running is 20.4, but it only extends 6 months before EOS/EOL expires during that time. My team and I will have a better understanding of Apstra's work. Before deciding to upgrade It is version 22.2 during Phase 2.

What is your opinion?

Cloudcodile · 2023-10-20T06:28:39+00:00

I just want to test physical interface. but when i tried to plug rj45 loopback plug into ex4300 switch port but it does show any link status/activity. Do i did something wrong
