Hello guys,
How third-party device work with 802.1AE 0x888e frame?
For example we need create this Topology
EX4300 macsec port -------access port SW access port ---------macsec port EX4300.
its should work?

Re: Encryption between two Sites connected through Metro-E
Does your intermediate switch support MACSEC? If yes, then 'theoritcally' this should work but may need some tweaking to get settings properly done. If not, and device is indeed a switch, then answer is most likely will not work,ever. MACSEC is a point-to-point protocol and is not designed to support pass-through where MAC headers would change. I would fully expect the MACSEC link to not even come up - key exchange will fail.
Now if your intermediate device acted like a 'hub' then it might work. Likewise, IPSEC, would also not work in such a configuration, without IPSEC support at intermediate SW.
Good luck.

Re: EX4600 RDMA over Converged Ethernet (RoCE) support?
Just FYI. This enhanced supported is scheduled for 17.4 release, but will most likely only be supported (tested) with QFX5110, at least at that time frame. For any new deployments, people should only consider QFX5110, and not QFX5100. Whether EX4600 also receives this support is to be determined.
Again, just FYI.

Re: Encryption between two Sites connected through Metro-E
i try test in lab:
EX4300 macsec port >>> bridge domain MX >>>> macsec port EX4550
this not working
EX4300 macsec port >>> L2Circ/connections MX >>>> macsec port EX4550
this working.
I don't understand why we can't wrap our 802.1AE in 802.1Q, then we will be able to forward on TAGs 802.1q
cisco support:
Support for VLAN tag in the clear option to enable Carrier Ethernet Service Multiplexing.

Enable flow-control RX on TX off EX4550
Dear All
I have a pair of EX 4550 running 12.3R7.7 in a virtual Chassis as dedicated iSCSI switches, we have been having xome issue with one of the storage units connected to the switches and the manufacture says we need to enable flow-control and have RX on and TX off.
When I connect to the switches the only option I have is to enable flow-control under ether-opitions or no-flow-control.
Does any one know is this a feature in a newer version of junos?
From some research I can see it is possible on the 4600 but can not find anything for the 4550.
Regards
Richard

STP on ex4550
Hi,
we have ex4550 as core with ex4300 as edge switches. I would like to setup another ex4550 as an edge switch due to its 10G ports. I am not farmilar with the vstp setup on this model.
since this is an edge, would something like this
set protocols vstp vlan all bridge-priority 60k
set protocols vstp vlan 10 interface xe-0/0/0.0 edge
thank you in advance.

Re: STP on ex4550
Why run any form of STP at all? STP designs (outside of Cisco) went out 10+ years ago. Just change the 2 x 10GE connections from remote EX4550 to EX4550 in the code to an AE/LAG and you'll have active-active on both links, without need to STP.
With today's various other technologies, STP should really never be needed. Primary case (for Juniper) is interoperability with previously configured/designed Cisco networks. For EX to EX, you could also use default RSTP config to start with.

Re: Enable flow-control RX on TX off EX4550
I believe for EX4550 the only options are on or off for flow-control. You can not configure at the RX/TX levels.
For EX4600 and QFX51xx switches it is configureable at that level
Sorry!!

Re: Encryption between two Sites connected through Metro-E
Because in 1st case you are changing the frame, as MX acts like a switch. In 2nd it is just pass through, where MX functions more like dark fiber connection, with no frame manipluation.
It is the way MX config options work. I am sure for Cisco their config option does the same thing, just different command structure.
My 2 cents worth.

Re: Enable flow-control RX on TX off EX4550
Hi
Thank you for confirming that, such a basic reqirement on these switches but not supported. Hope Juniper get this sorted at some point.

VC EX2200 problem
Hi my VC ex2200 stoped forwarding packets. I found this in chasis log. Looks like virtual chasis issue.
Could you please help me what could cause this issue and what exactly could happen?

Re: promiscuous mode
I believe that link talks about how to set up promiscous mode on an SRX, generally used for off-line traffic analysis via a port mirror with a SRX.

Re: VC EX2200 problem
Looks like the virtual chassis interface connection dropped between the switches and was then restored.
Use the show interface command on the VC port and see when the "last flap" was. If this lines up with the time of the logs then the loss of link on the VC is confirmed.
