Configuring a Statistical Analyzer for Remote Traffic Analysis

user@switch# set analyzer employee-monitor output interface interface-name
For example, configure ge-0/0/10.0 as the destination interface for the mirrored
packets:
[edit forwarding-options]
user@switch# set analyzer employee-monitor output interface ge-0/0/10.0
Specify mirroring properties.
3.
a. Specify the mirroring rate—that is, the number of packets to be mirrored per second:
[edit forwarding-options]
user@switch# set analyzer employee-monitor input rate number
The valid range is 1 through 65,535.
b. Specify the length to which mirrored packets are to be truncated:
[edit forwarding-options]
user@switch# set analyzer employee-monitor input maximum-packet-length number
The valid range is 0 through 9216. The default value is 0, which indicates that mirrored
packets are not truncated.
To mirror traffic that is traversing interfaces or a VLAN on the switchto a VLAN for analysis
from a remote location by using a statistical analyzer:
Configure a VLAN to carry the mirrored traffic:
1.
[edit]
user@switch# set vlans vlan-name vlan-id vlan-ID
For example, configure a VLAN called
[edit]
user@switch# set vlans remote-analyzer vlan-id 999
Set the uplink module interface that is connected to the distribution switch to access
2.
mode and associate it with the VLAN:
[edit]
user@switch# set interfaces interface-name unit 0 family ethernet-switching interface-mode
access vlan members vlan-ID
For example, set the uplink module interface ge-0/1/1.0 that is connected to the
distribution switchto access mode and associate it with the
[edit]
user@switch# set interfaces ge-0/1/1.0 unit 0 family ethernet-switching interface-mode
access vlan members 999
Configure the statistical analyzer:
3.
Specify the traffic to be mirrored:
a.
[edit forwarding-options]
user@switch# set analyzer analyzer-name input ingress interface interface-name
For example, specify the packets entering ports ge-0/0/0.0 and ge-0/0/1.0 to be
mirrored:
[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
