The default behavior in congestion situations is to drop any excessive frames that may clog the

system.

5.10.1.5 Truncation

When enabled, the system can truncate the mirrored packets into smaller 64-byte packets

efault) which is enough to capture the packets’ L2 and L3 headers.

5.10.2 Configuring Mirroring Sessions

Figure 13 presents two network scenarios with direct and remote connectivity to the analyzer

equipment. Direct connectivity is

when the analyzer is connected to the analyzer port of the

switch. In this case there is no need for adding an L2 header to the mirrored traffic. Remote con-

nectivity is when the analyzer is indirectly connected t

o the analyzer port of the switch. In this

situation, adding an L2 header may be necessary depending on the network’s setup.

Figure 13: Mirroring Session

 To configure a mirroring session:

Step 1. Create a session. Run:

Step 2. Add source interface(s). Run:

ETS, PFC and FC configurations do not apply to the destination port.

switch (config) # monitor session 1

This command enters a monitor session configuration mode. Upon first implementa-

tion the command also creates the session.
