OL-7396-01
Use tag switching functionality with caution. Do not distribute routes learned through tag switching
to FE or GE, or vice versa. Otherwise, you might have unreachable route destinations.
The ATM router module does not initialize if it replaces an ATM port adapter or interface module
when hierarchical VP tunnels are globally enabled. Reboot the switch to initialize the ATM router
module.
ATM Director does not support any PVC commands.
Only LANE clients or RFC 1483, not both, can be configured on an ATM router module interface.
RFC 1483 on the ATM router module supports only AAL5 SNAP encapsulation.
Even though each ATM router module interface supports a maximum of 2048 VCs, only
1400 to 1500 external VCs can be configured. Internal VCs use up the rest.
IP multicast is only supported over 1483 LLC/SNAP encapsulated PVCs.
You can have a maximum of 64 LECs per chassis.
Do not install an ATM router module in a slot pair where hierarchical VP tunnels are configured.
Slot pairs 0 and 1, 2 and 3, 9 and 10, and 11 and 12 use the same switching modules for scheduling.
For example, do not install an ATM router module in slot 10 when hierarchical VP tunnels are
configured on slot 9. For more information on hierarchical VP tunneling restrictions, see
"Configuring Virtual Connections."
Token Ring LANE is not supported.
Tag-edged router functionality is not supported.
Fast Simple Server Redundancy Protocol (SSRP) is not supported.
Bridging for multiplexing device encapsulation is not supported.
PIM IP multipoint signalling is not supported.
PIM NBMA is not supported.
PIM over ATM multipoint signalling is not supported.
Translation from IP QoS to ATM QoS is not supported.
RSVP to ATM SVC is not supported.
PVC management using ILMI is not supported.
Access lists for ATM to ATM routing is not supported.
Half-bridge devices are not supported.
RFC 1483 MUX encapsulation is not supported.
IP multicast over RFC 1483 SVCs are not supported.
ACLs for IP, and standard ACLs for IPX is not supported.
IP fragmentation is not supported.
IP 6-path load balancing is not supported.
