    Rev 1.6.9 There is no limitation on the number of mirroring sources and more than a single source can be mapped to a single analyzer destination. 5.10.1 Mirroring Sessions Port mirroring is performed by configuring mirroring sessions. A session is an association of a mirror port (or more) and an analyzer port.
  • Page 82 Rev 1.6.9 There is no limitation on the number of the source interfaces mapped to a mirroring session. Ingress and egress traffic flows of a specific source interface can be mapped to two dif- ferent sessions. The source interface can be a physical interface or a LAG. Port mirroring can be configured on a LAG interface but not on a LAG member.
  • Page 83 Rev 1.6.9 The system on the receiving end of the analyzer port must be set to handle the egress traffic. If it is not, it might discard it and indicate this in its statistics (packet too long). 5.10.1.3 Header Format Ingress traffic from the source interface can be manipulated in several ways depending on the network layout using the command header-format.

    Rev 1.6.9 The default behavior in congestion situations is to drop any excessive frames that may clog the system. ETS, PFC and FC configurations do not apply to the destination port. 5.10.1.5 Truncation When enabled, the system can truncate the mirrored packets into smaller 64-byte packets (default) which is enough to capture the packets’...
