Network And System Management; Performance Management; Bandwidth Capacity - NETGEAR SRX5308 - ProSafe® Quad WAN Gigabit SSL VPN Firewall Reference Manual

This chapter describes the tools for managing the network traffic to optimize its performance and
the system management features of the VPN firewall. This chapter contains the following sections:
• "Performance Management" on this page
• "System Management" on page 8-8

Performance Management

Performance management consists of controlling the traffic through the VPN firewall so that the
necessary traffic gets through when there is a bottleneck and either reducing unnecessary traffic or
rescheduling some traffic to low-peak times to prevent bottlenecks from occurring in the first
place. The VPN firewall has the necessary features and tools to help the network manager
accomplish these goals.

Bandwidth Capacity

The maximum bandwidth capacity of the VPN firewall in each direction is as follows:
• LAN side. 4000 Mbps (four LAN ports at 1000 Mbps each)
• WAN side
– Load balancing mode. 4000 Mbps (four WAN ports at 1000 Mbps each)
– Auto-rollover mode. 1000 Mbps (one active WAN port at 1000 Mbps)
– Single-WAN port mode. 1000 Mbps (one active WAN port at 1000 Mbps)
In practice, the WAN side bandwidth capacity is much lower when DSL or cable modems are used
to connect to the Internet. At 1.5 Mbps, the WAN ports support the following traffic rates:
• Load balancing mode. 6 Mbps (four WAN ports at 1.5 Mbps each)
• Auto-rollover mode. 1.5 Mbps (one active WAN port at 1.5 Mbps)
• Single WAN port mode. 1.5 Mbps (one active WAN port at 1.5 Mbps)
