Chapter 10

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

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 ( UTM25 or UTM10): 2000 Mbps (two LAN ports at 1000 Mbps each)

WAN side: 2000 Mbps in load balancing mode (UTM25 only: two WAN ports at 1000 Mbps

each), 1000 Mbps in auto-rollover mode (UTM25 only: one active WAN port at 1000 Mbps),

or 1000 Mbps in single WAN port mode (UTM25 or UTM10: 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 (UTM25 only): 3 Mbps (two WAN ports at 1.5 Mbps each)

Auto-rollover mode (UTM25 only): 1.5 Mbps (one active WAN port at 1.5 Mbps)

Single WAN port mode (UTM25 or UTM10): 1.5 Mbps (one active WAN port at 1.5 Mbps)

As a result, and depending on the traffic that is being carried, the WAN side of the UTM is the limiting factor to throughput for most installations.
