5. Configure remote VLAN of mirror group
37.3 Typical Examples of RSPAN
Before RSPAN is invented, network administrators had to connect their PCs directly to the
switches, in order to check the statistics of the network.
However, with the help of RSPAN, the network administrators can configure and supervise the
switches remotely, which brings more efficiency. The figure below shows a sample application
of RSPAN.
RSPAN Application Sample
Two configuration solutions can be chosen for RSPAN: the first is without reflector port, and
the other is with reflector port. For the first one, only one fixed port can be connected to the
intermediate switch. However, no reflector port has to be configured. This maximizes the
usage of witch ports. For the latter one, the port connected to the intermediate switch is not
fixed. Datagrams can be broadcasted in the RSPAN VLAN through the loopback, which is
much more flexible.
The normal mode configuration is show as below:
Solution 1:
Source switch:
Interface ethernet 1/0/1 is the source port for mirroring.
Interface ethernet 1/0/2 is the destination port which is connected to the intermediate switch.
RSPAN VLAN is 5.
