FortiSwitch-5003A configurations FortiSwitch-5003A system
Layer-2 link aggregation and redundancy configurations
The FortiSwitch-5003A board supports 802.3ad layer-2 link aggregation, 802.1q
VLANs, and 802.1s Multi-Spanning Tree Protocol (MTSP) for the fabric channels.
You can use these features to configure link aggregation and support redundant
FortiSwitch-5003A switch configurations to distribute traffic to multiple
FortiGate-5000 boards.
See the FortiGate-5000 Backplane Communication Guide for more information
about FortiSwitch-5003A link aggregation and redundancy.
Figure 6 shows a basic link aggregation configuration using a single
FortiSwitch-5003A board. In this configuration the external switch is connected to
FortiSwitch-5003A front panel f5 interface. The switch adds VLAN tags to traffic
from the internal and external networks.
