Juniper JUNOS OS 10.3 - SOFTWARE, Manual

NOTE: Because the Packet Forwarding Engine removes Layer 2 header
information before sending packets to the Routing Engine:
•
The monitor traffic command cannot apply match conditions to inbound
traffic.
•
The monitor traffic interface command also cannot apply match conditions
for Layer 3 and Layer 4 packet data, resulting in the match pipe option (|
match
) for this command for Layer 3 and Layer 4 packets not working
either. Therefore, ensure that you specify match conditions as described
in this command summary. For more information about match conditions,
see Table 507 on page 3835.
•
The 802.1Q VLAN tag information included in the Layer 2 header is removed
from all inbound traffic packets. As the monitor traffic interface ae[x]
command for aggregated Ethernet interfaces (such as ae0) only shows
inbound traffic data, the command does not show VLAN tag information
in the output.
