Network and System Management
This chapter describes the tools for managing the network traffic to optimize its performance and
the system management features of the UTM. This chapter contains the following sections:
• “Performance Management” on this page.
• “System Management” on page 10-9.
Performance Management
Performance management consists of controlling the traffic through the UTM 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 UTM has the necessary features and tools to help the network manager accomplish
these goals.
Bandwidth Capacity
The maximum bandwidth capacity of the UTM in each direction is as follows:
• LAN side (single-WAN port models and dual-WAN port models):
2000 Mbps (two LAN ports at 1000 Mbps each)
•WAN side:
– Load balancing mode (dual-WAN port models only): 2000 Mbps (two WAN ports at
1000 Mbps each)
– Auto-rollover mode (dual-WAN port models only): 1000 Mbps (one active WAN port at
1000 Mbps)
– Single-WAN port mode (single-WAN port models and dual-WAN port models):
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 (dual-WAN port models only): 3 Mbps (two WAN ports at 1.5 Mbps
each)
