Port mirroring monitors and mirrors network traffic by forwarding copies of incoming and outgoing packets
from up to four source ports to a monitoring port. The switch also supports flow-based mirroring, which
allows you to copy certain types of traffic to a single destination port. This provides flexibility—instead of
mirroring all ingress or egress traffic on a port the switch can mirror a subset of that traffic. You can
configure the switch to mirror flows based on certain kinds of Layer 2, Layer 3, and Layer 4 information.
QNOS supports up to four monitor sessions. Port mirroring, flow based mirroring, RSPAN, and VLAN
mirroring can be configured at the same time on the switch using different sessions IDs and in any
combinations. Any two sessions cannot be identical. Multiple mirroring sessions are supported for all types
of mirroring.
A given interface can be used as a source interface for different sessions. For example a mirroring session
can be created with source interface as port A and destination interface as port B. Another session can be
created with source interface as port A and destination interface as port C. An interface cannot be
configured as a destination interface for more than one session.
An IP/MAC access-list can be attached to any mirroring session or to all sessions at the same time.
1.1.24. sFlow
sFlow is the standard for monitoring high-speed switched and routed networks. sFlow technology is built
into network equipment and gives complete visibility into network activity, enabling effective management
and control of network resources. The switch supports sFlow version 5.
1.1.25. Static and Dynamic MAC Address Tables
You can add static entries to the switch’s MAC address table and configure the aging time for entries in the
dynamic MAC address table. You can also search for entries in the dynamic table based on several different
criteria.
1.1.26. Link Layer Discovery Protocol (LLDP)
The IEEE 802.1AB defined standard, Link Layer Discovery Protocol (LLDP), allows the switch to advertise
major capabilities and physical descriptions. This information can help you identify system topology and
detect bad configurations on the LAN.
1.1.27. Link Layer Discovery Protocol (LLDP) for Media Endpoint Device
The Link Layer Discovery Protocol for Media Endpoint Devices (LLDP-MED) provides an extension to the
LLDP standard for network configuration and policy, device location, Power over Ethernet management,
and inventory management.
1.1.28. DHCP Layer 2 Relay
This feature permits Layer 3 Relay agent functionality in Layer 2 switched networks. The switch supports L2
DHCP relay configuration on individual ports, Port-channels and VLANs.
