External network: though optical fiber transceiver transfer a twisted pair connects to the peer vendor’s anti-poison wall.
Peer vendor’s anti-position wall: uses transport mode, up connects to the Netcom optical fiber transceiver, down connects to the peer vendor’s switch.
USG3040 firewall: A and B do two node cluster hot backup, the twisted pair connects to peer vendor’s switch; A and B connect each other through optical fiber, which connects the core switch S9306.
S9306: two optical ports on switch connect USG firewall A and B; through the twisted pair connects to server; on switch two ports do port aggregation, through fiber connects S2300 switch.
S2300: switch through optical fiber connect to the core switch.
