Emulation of the following hardware:

- MIPS64 and PowerPC CPU processors. The instruction sets are not completely emulated now (MIPS FPU support is lacking, TLB support is not finished and other minor things), but it is sufficient for IOS
- DRAM and Packet SRAM memory
- Non-Volatile Memory (NVRAM)
- Signetics SCN 2681 DUART (C7200 Console and AUX ports)
- National Semiconductors NS16552 DUART (C3600/C3700/C2600 Console/AUX ports)
- Dallas DS1620 Temperature Sensors and Voltage Sensors, allowing the C7200 Environmental Monitor to work properly
- NMC93C46 Serial EEPROM
- Bootflash of 8 Mb (Intel 28F016SA)
- Galileo GT64010/GT64120/GT96100 PCI controllers, DEC 21×50 PCI bridges and so
- PCMCIA ATA disk emulation (C7200 only at this time)

Non router hardware specific features:

- Ability to bridge Ethernet adapters on the emulated hardware with a NIC on the host PC. This allows you to connect the emulated router directly to the network the host computer is plugged into. For example, you might want an emulated router to interact somehow with an existing real network for some testing purposes. This is possible by using the PC network adapter to transparently bridge an emulated router interface. Another useful combination is using a network interface on the host pc (such as a loopback) to communicate with router interfaces in the virtual network.

- Capture packets on virtual Ethernet or Serial interfaces and write the output to a capture file for use with applications like tcpdump, Wireshark, or any other application that can read the libpcap capture file format.
