same FPC, repeat Step 3 and specify a different statistical analyzer name:
[edit chassis fpc slot-number]
user@switch# set port-mirror-instance stats_analyzer-2
Verify the minimum configuration of the binding:
5.
[edit chassis fpc slot-number port-mirror-instance analyzer_name]
user@switch# top
[edit]
user@switch# show chassis
chassis {
fpc slot-number { # Bind two statistical analyzers or port mirroring
port-mirror-instance stats_analyzer-1;
port-mirror-instance stats_analyzer-2;
}
}
NOTE: On binding a second instance (
mirroring properties of this session, if configured, overrides any default
analyzer.
On EX9200 switches, you can mirror traffic to multiple destinations by configuring
next-hop groups as analyzer output. The mirroring of packets to multiple destinations is
also known as multipacket port mirroring.
To mirror interface traffic or VLAN traffic on the switchto an interface on the switch (by
using analyzers):
Choose a name for the analyzer and specify the input:
1.
[edit forwarding-options]
user@switch# set analyzer analyzer-name input ingress interface interface-name
For example, create an analyzer called
comprises packets entering interfaces ge-0/0/0.0 and ge-0/0/1.0:
[edit forwarding-options]
user@switch# set analyzer employee-monitor input ingress interface ge–0/0/0.0
[edit forwarding-options]
user@switch# set analyzer employee-monitor input ingress interface ge–0/0/1.0
Configure the destination interface for the mirrored packets:
2.
[edit forwarding-options]
user@switch# set analyzer analyzer-name output next-hop-group next-hop-group-name
For example, configure the next-hop group
employee-monitor analyzer:
[edit forwarding-options]
user@switch# set analyzer employee-monitor output next-hop-group nhg
