Cisco ASA 5540 Features

Next in the line is the Cisco ASA 5540 Firewall appliance. This device is geared towards large enterprises which need firewall throughput of 650Mbps. The ASA 5540 is the highest model that supports a Security Services Module (SSM) in order to offer Content Inspection or Intrusion Prevention IPS services to the network. The SSM module can host also a four-port Gigabit Ethernet card, in addition to the Content Inspection or IPS modules. The higher-end models 5550 and 5580 DO NOT support the SSM module. Note also the greatly enhanced number of supported VPN sessions (5000 or 2500 for SSL VPN) compared with smaller models. This enhancement makes the 5540 ideal for replacing the older VPN 3000 Concentrator device.
