Network Management and Monitoring

  • On-box packet sniffing support (EX4100-48MP, EX4400-48MP, EX4650, QFX5110, QFX5120-32C, QFX5120-48T, QFX5120-48Y, and QFX5120-48YM)—We’ve introduced on-box packet sniffing capability to monitor and analyze network traffic on ports without using an external device, such as collector or an agent.

    On-box packet sniffer allows you to monitor IPv4 packets on ingress or egress ports, matching them based on header attributes like source IP, destination IP, source MAC, destination MAC, VLAN, and VNID. You can store the sniffed packets in pcap format.

    This feature reduces costs and simplifies debugging.

    We’ve introduced the following configuration statements to support this feature:

    • To enable the tracing operations, configure the set services pfe traffic traceoptions file filename statement.

    • To increase the default timer that is set for uninstalling the filter and deleting the entries, configure the set services pfe traffic monitor-timer time statement.

    • To enable egress packet monitoring, configure the set interface interface-name ether-options loopback statement. You must configure an additional unused interface for a virtual loopback interface to achieve egress packet monitoring.

    Use the following commands to monitor data packets and verify the functionality of on-box packet sniffing:
