Access switch
As shown in Figure 1-8, the ACs are only connected to an aggregation switch on a Layer 2
network. Data packets from STAs are forwarded in direct mode. AC1 is the active AC, and
AC2 is the standby AC.
The configuration notes in this networking are as follows:
The configuration notes are the same as those in Layer 2 chain networking (direct
forwarding).
In addition, the BRAS interface connected to the aggregation switch must work at Layer 2 to
ensure Layer 2 communication between the ACs and APs. For the BRAS configuration, see
the configuration guide of the BRAS.
