Greetings, this is possible here is a sample of the configuration that would do the job:Ĭonfiguring Port Mirroring for Remote Traffic Analysis (ELS) I'm considering reinstall the Ciscos for the mirror traffic distribution. 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.

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. *) Scenario: host X is sending to upstream A and B. Or do I just not understand what an RSAPN tag is? Still (up to current releases) there is that typo: "Removes extra RSAPN tag from mirrored packets". Having no-tag would be a great option on destionation interface! 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. Why not? Not the same port might make sense, but Vlan? Ex4300 (the Ex4200 can have only one active analyzer!): Two analyzers cannot have the same destination Vlan.
MAC ADDRESS LEARNING IN RSPAN MAC
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! *) Ex4200: RSPAN Vlan destination is supported, but not on aggregated ethernet. Ex4300 RSPAN Vlan destination is supported, but traffic is sent out only on _one_ interface. It is unbelievable how many restrictions there are in Juniper compared to Cisco:
