3.2.8 Configuring the Working Mode of EA LPUs
I. Introduction to the working mode of EA LPUs
The S7500E series Ethernet switches support multiple types of LPUs. If you need to
extend the MAC address table or the routing table, you can purchase EA LPUs, that is,
the LPUs with the last two letters of the LPU model being EA, LSQ1GP12EA for
example.
An EA LPU can work in either of the two modes: MAC extension (bridging) and route
extension (routing).
z MAC extension mode: The LPU can provide a 128K MAC address table. It is
recommended to use this mode in a Layer 2 network with a large MAC address
table.
z Route extension mode: The LPU can provide a 128K routing table. It is
recommended to use this mode in a Layer 3 network with a large routing table.
