Table 482: Port Mirroring Configuration Settings

Field Function
Analyzer Specifies the name of the analyzer.
Name
Ratio Specifies the ratio of packets to be mirrored. For example:
A ratio of 1 sends copies of all packets.
A ratio of 2047 sends copies of 1 out of every 2047 packets.
On EX8200 switches, you can set a ratio only for ingress
packets.
Loss Priority Specifies the loss priority of the mirrored packets.
By default, the switch applies a lower priority to mirrored data
than to regular port-to-port data—mirrored traffic is dropped
in preference to regular traffic when capacity is exceeded.
For port mirroring configurations with output to an analyzer
VLAN, set the loss priority to high.
Analyzer Port Specifies a local interface or VLAN to which mirrored packets
are sent.
NOTE: A VLAN must have only one associated interface to
be specified as an analyzer interface.
