ATM Limitations

The following limitations apply to ATM support on Circuit Emulation PICs:

• Packet MTU—Packet MTU is limited to 2048 bytes.
• Trunk mode ATM pseudowires—Circuit Emulation PICs do not support trunk mode ATM pseudowires:
• OAM-FM segment—Segment F4 flows are not supported. Only end-to-end F4 flows are supported.
• IP and Ethernet encapsulations—IP and Ethernet encapsulations are not supported.
• F5 OAM—OAM termination is not supported.
