SRX

Hello,

Does port mirroring work on SRX340?

I was tried to configure this feature based on this:

https://kb.juniper.net/InfoCenter/index?page=content&id=KB21833

but it doesn't work.

I see that couter in filter increase, but I don't see any packets on outging interface.

Best Regards

Hello,

If You follow this KB, there is a bit of configuration missing, namely, static ARP on port-mirror output interface.

For the KB example config, it would be

set interfaces ge-0/0/1.0 family inet address 2.2.2.1/24 arp 2.2.2.2. mac 0e:00:00:00:00:0e 

Please add static ARP entry to Your config, re-test and report back.

Thx

Hello,

Please send traffic thru ge-0/0/0 and share the following printouts:

show forwarding-options port-mirroring | no-more
show interfaces ge-0/0/0 extensive | no-more
show interfaces ge-0/0/7 extensive | no-more

Thx

I attached the file.

I see:

root> show forwarding-options port-mirroring | no-more
Instance Name: &global_instance
Instance Id: 1
Input parameters:
Rate : 1
Run-length : 0
Maximum-packet-length : 0
Output parameters:
Family State Destination Next-hop
inet down ge-0/0/7.0

but Physical interface is UP.

Hello,

I noticed that I made a mistake in the subject. It should be SRX340
