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
Specify an output for the analyzer:
b.
[edit forwarding-options]
user@switch# set analyzer analyzer-name output vlan vlan-ID
For example, specify the
[edit forwarding-options]
user@switch# set analyzer employee-monitor output vlan 999
Specify mirroring properties.
4.
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 means the mirrored
packets are not truncated.
You can bind a statistical analyzer to a specific FPC in the switch, that is, you can bind
the statistical analyzer instance at the FPC level of the switch. The mirroring properties
specified in the statistical analyzer are applied to all physical ports associated with all
Packet Forwarding Engines on the specified FPC.
To bind a named instance of Layer 2 analyzer to an FPC:
Enable configuration of switch chassis properties:
1.
[edit]
user@switch# edit chassis
Enable configuration of an FPC (and its installed PICs):
2.
[edit chassis]
user@switch# edit fpc slot-number
Bind a statistical analyzer instance to the FPC:
3.
VLAN as the output for the analyzer:
