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.
