• tx — Mirrors transmitted packets only. If no option is specified, monitors
both rx and tx.
• both —Mirrors both ingress and egress. This is the default.
• mode —Enable session mirroring. Use the no form of the command to
disable monitoring.
• remove-rspan-tag —Remove the RSPAN tag from packets transmitted on
the probe port. This option is not available on the N4000 Series switches.
Default Configuration
The default is to mirror both transmit and receive directions. If neither tx or
rx is configured, both directions are monitored.
Command Mode
Global Configuration mode
User Guidelines
Use the source interlace parameter to specify the interface to monitor. Use rx
to monitor only ingress packets, or use tx to monitor only egress packets. If
you do not specify an rx or tx option, the session monitors both ingress and
egress packets. Use the destination interface to specify the interface to receive
the monitored traffic. Use the mode parameter to enabled the administrative
mode of the session. If enabled, the destination (probe) port monitors all the
traffic received and transmitted on the physical monitored port. The probe
port should not be connected to a network. Connect it to a monitoring tool or
a standalone (static IP address) workstation running a monitoring program.
Up to four sessions mirroring traffic in a single direction and with unique
destinations are supported on the Dell EMC Networking N2000, N2100-ON,
N3000, N3100-ON, and N4000 Series switches. The Dell EMC Networking
N1100-ON and N1500 Series switches support a single unidirectional or
bidirectional session. Each session supports multiple sources. However, the
destination interface for a session may not overlap with other sessions. The
internal CPU port cannot be configured as an RSPAN source.
The session limitations are as follows (N2000, N2100-ON, N3000, N3100-
ON, N4000 only):
• Up to 4 sessions in ingress (RX) traffic mirroring may be active.
