S7700 and S9700 series modular switches configured with SPUs support NAT. 3. S9300 series modular switches configured with SPUs support NAT. 4. S12700 series modular switches do not support NAT.

Which impedance modes do FXS interfaces on a 4FXS1FXO interface card support
FXS interfaces on a 4FXS1FXO interface card support two DC impedance modes: 50 ohm (default) and 800 ohm. FXS interfaces on a 4FXS1FXO interface card support three AC impedance modes: 600 ohm (default), 270+(750||150 nF) ohm, and 275+(780||150 nF).

What type of interfaces can VLANs be configured
Currently, the following Ethernet interface types are defined on the AR router: 1. Layer 2 Ethernet interfaces: They are physical interfaces working at the data link layer. These interfaces cannot be configured with IP addresses, but can forward received packets at Layer 2 or be added to VLANs to forward packets at Layer 3 through corresponding VLANIF interfaces. 2. Layer 3 Ethernet Interfaces: They are physical interfaces working at the network layer. These interfaces cannot be added to VLANs, but can be configured with IP addresses and forward received packets at Layer 3.
