Hi, I've currently successfully gotten port mirroring setup to more than one port, using the following config:
port-mirroring { family inet { output { next-hop-group default-collect; } } next-hop-group default-collect { group-type inet; interface ge-1/3/2.0 { next-hop 192.168.10.2; } interface ge-1/3/5.0 { next-hop 192.168.20.2; } } router> show configuration interfaces ge-1/3/2 unit 0 { family inet { address 192.168.10.1/30 { arp 192.168.10.2 mac 00:1b:21:86:a2:92; } } family inet6 { address fdb5:1281:f3cf:c7c4::1/64 { ndp fdb5:1281:f3cf:c7c4::2 mac 00:1b:21:86:a2:92; } } } router> show configuration interfaces ge-1/3/5 unit 0 { family inet { address 192.168.20.1/30 { arp 192.168.20.2 mac 00:1b:21:86:a3:9a; } } family inet6 { address fd3d:122a:8541:ecb5::1/64 { ndp fd3d:122a:8541:ecb5::2 mac 00:1b:21:86:a2:93; } } } This works very nicely, I see traffic at both measurement hosts. I would like to do the same for IPv6, but there's no next-hop-group setting available: [edit forwarding-options port-mirroring family inet6 output] router# set ? Possible completions: + apply-groups Groups from which to inherit configuration data + apply-groups-except Don't inherit configuration data from these groups > interface Interfaces through which to send sampled traffic no-filter-check Do not check for filters on port-mirroring interface [edit forwarding-options port-mirroring family inet6 output] This limitation is actually mentioned in the documentation, here: http://www.juniper.net/techpubs/en_US/junos12.2/topics/usage-guidelines/services-configuring-port-mirroring.html "Port mirroring supports up to 16 next hops, but there is no next-hop group support for inet6." However I was wondering perhaps someone knows if there's a trick to this using filter based forwarding? I can't really figure out how from the examples given. This is an MX80 on JunOS 11.2R3.3 Thanks! ~paul _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
