Thank you for your reply lyndidon, but Im trying on only one switch

The official note is TSB17030 -  https://kb.juniper.net/InfoCenter/index?page=content&id=TSB17030&smlogin=true&actp=search 

 

The

PRODUCT AFFECTED:

MPC7E-10G


MPC7E-MRATE


MX2K-MPC8E


MX2K-MPC9E


EX9200-12QS


EX9200-40Xs


FPC3-PTX-U2


FPC3-PTX-U3


FPC3-SFF-PTX-U1


CB2-PTX


PTX-IPLC-B-32


PTX-ILA-M-AC


PTX-ILA-M-CHAS

 

The only switching products affected are the latest module for EX9200, which have not been out long enough to even get near the time period for potential failure.  Juniper is addressing this whole situation, a lot more customer centric than Cisco for sure.

ok I see. Could you show this output?

show vlans klient1 extensive

One thing i would like to see from your test.

remove or deactive the irb. then ping host 1 on klient1 from host on klient2

activate the irb and repeat the same. i am really more curious now about this els. I don't have any such systems to test so I have to rely on the efforts of you and others with such experience.

I have already checked it. Without L3 interface IRB on primary vlan those devices in different communities don't see each other. The thing is that i need routing between community vlans.

 

I have got VC EX3400. Feature explorer say that it support IRB on PVLAN, but manual say it doesnt support RVI on PVLAN.

Junos allow me to configure irb on PVLAN, but it doesnt work.  From switch to hosts broadcast arp requests get, but there is no answer come back to switch. 

Ouput drops on ex3300/ex4200 after upgrading to 15.1R5.5

Hi J-net. After upgrading several our ex3300/4200 chassiss we've got increasing output drops on "ge" interfaces.

 

user@switch> show interfaces ge-0/0/25 extensive | match Drops:
Errors: 0, Drops: 0, Framing errors: 0, Runts: 0, Policed discards: 0, L3 incompletes: 0, L2 channel errors: 0, L2 mismatch timeouts: 0, FIFO errors: 0,
Carrier transitions: 0, Errors: 0, Drops: 2195782, Collisions: 0, Aged packets: 0, FIFO errors: 0, HS link CRC errors: 0, MTU errors: 0,

 

So far I can't see any impacts caused by those drops but our zabbix started to comlane a lot. Has anyone had the same "issues" or it just can be ingnored (I haven't found such behavior in Release Notes)

Yeah, Intel really messed up on this one.  Cisco had the misfortune to use this chip on a LOT of devices.  Luckily for us Juniper only had this on a limited set.

 

Still waiting for the other shoe to drop with all the other major vendors as they sort out where they used this chip and if the design hits the bug.

There are 12 open PR for 15.1R5.5 with drop conditions listed.

 

https://prsearch.juniper.net/InfoCenter/index?page=prsearch#qt=drop&bv=15.1R5&sid=ex&dt=0&mode=simpleall&start=0&srtBy=igeneric1&rs=2&nsl=_007!generic2!Open!Y|_006!docdatetime!0!N|_002!junosversion!2!N

 

I would check to see if your configuration usage would match any of these known issues.  None of them are cosmetic but actual traffic drops.

 

If you don't seem to match an existing PR, I would open a JTAC ticket and have the issue investigated.

Re: Remote port mirror configuration for JUNIPER EX-switch and Cisco switch

$

It is unbelievable how many restrictions there are in Juniper compared to Cisco:

 

- Ex4300 RSPAN Vlan destination is supported, but traffic is sent out only on _one_ interface. Which one is not deterministic. RSPAN vlan ist NOT flooded to all ports.

- Ex4200: RSPAN Vlan destination is supported, but not on aggregated ethernet.

- Ex4300/Ex4200: Even in a Vlan configured with no-mac-learning (all show commands show "mac * -> Flood", no MAC addressed, a.s.o): if a second port will receive frame with same MAC address, only one of the two frames is forwarded! *)

- Ex4300 (the Ex4200 can have only one active analyzer!): Two analyzers cannot have the same destination Vlan. Why not? Not the same port might make sense, but Vlan?

- Ex4300: destionation option "no-tag" is only possible on destination vlan? What's that for? It would be reasonable, if it strips the inner Vlan - but it stripps the outer (the RSPAN) tag! IMHO this is just a bug. Having no-tag would be a great option on destionation interface!

- Still (up to current releases) there is that typo: "Removes extra RSAPN tag from mirrored packets". Or do I just not understand what an RSAPN tag is?

 

*) Scenario: host X is sending to upstream A and B. Port mirror on link to A and B because we want to prove that it is sent out! If A and B is on two different switches, you will see only one stream on the destination switch for the RSPAN vlan.

 

I'm working hard for 4 weeks now to find a suitable concept permanentely mirror my plattform and feed that into our traffic analyzer as we did with the Ciscos before. I'm considering reinstall the Ciscos for the mirror traffic distribution. Can that be?

Sorry very confused by your latest statements.  If you want routing/communication between the communities why are you using PVLAN in the first place?  Is the idea that communities can only talk to each other once they hit some Security point, like say a FW?

 

What is the subnet mask associated with the IRB and what is the subnet mask of the communities.  Does a community know it needs to route (from an IP perspective) if it is trying to reach a different community?

 

Trying to figure out the big picture requirement, not just if IRB works with PVLAN, . . .

vQFX10k 15.1X53-D60 3 BUGS on MC-LAG (one fatal) :(

  1. Parser bug for redundancy-group

 

unlike the QFX5k the vQFX10k needs the redundancy-group and redundancy-group-list setting

if omitted you get a cryptic commit error:

 

error: Failed Reading Default configuration database:

 

error: configuration check-out failed

so you need to set:

 

set protocols iccp peer <peer-ip> redundancy-group-id-list 1

 

 

and then if you have any MC-LAGs configured yet, do:

 

 

set interfaces aeX aggregated-ether-options mc-ae redundancy-group 1

 

 BUT on vQFX10k ....

 

 

{master:0}[edit]

lab@QFX53# set interfaces ae4 aggregated-ether-options mc-ae ?

Possible completions:

  init-delay-time      Init delay timer for mcae sm for min traffic loss

PPPoE through flexible-ethernet-services

$

Hi all,

 

I need some guidance here. Here is my setup:

 

PPPoE Client Router  ---->  SW1  ----->  R1  ------>  R2-BRAS

 

I want to use the BRAS at R2 to terminate my PPPoE session from the PPPoE client router.

 

The client router connects to SW1 on access port vlan id 4004. Then the vlan is bridged as a bridged domain all the way to the BRAS. The thing is, i am not sure how to terminate this VLAN on the BRAS so it can enjoy PPPoE services and the link from R1 to R2-BRAS is not trunked but rather flexible-ethernet-services with vlan bridges.

 

R1 and R2-BRAS are MX series routers.

 

Let me know if i am not making any sense and i will elaborate some more.

 

Thanks

Dot1x / MAC-Based Authentication issues on a EX2200 with 100BaseEthernet Devices

$

Hi everybody,

 

I have some issues with 100BaseEthernet devices on a EX2200 with activated MAC-Based Security on specific Ports.

When I connect a device with a 100Mbit Ethernet on a dot1x-Port the device MAC does not get authenticated. The authenticator on the switch stays on "Connecting":

 

 

Interface     Role            State
ge-0/0/34.0   Authenticator   Connecting

 

 

The Switch has the latest Firmware (JTAC recommended) installed: 15.1R5.5

I can reproduce this behavior with some other 100Mbit devices. 1Gbit devices get authenticated without any issues.

 

Thank you in advance.

 

P.S.: Sorry for my writing but English is not my first language.
