NTELLIGENT WITCHING OFTWARE
The following system issues have been identified for software
version 8.1.2:
When a ping is initiated from the CoreBuilder 2500 system and is
destined to an ATM device that has a specific ATM adapter card,
multiple pings are required before communication is initiated. This
situation arises because of the amount of time required for the
adapter card to resolve ATM ARP.
An ATM LEC cannot be configured as the backbone port in Express
Switching mode.
After you set a system baseline, ATM LEC bridge statistics are
incorrect.
You cannot set the ipDefaultTTL MIB variable.
When the ILMI autoconfiguration option is enabled on a
CoreBuilder 7000 switch, it could take several minutes for a LEC
configured on a CoreBuilder 2500 to join an emulated LAN.
Packet filters can access data only through byte 64 in the packet.
Roving Analysis frames that are sent over a remote Fast Ethernet
connection are truncated if greater than 1495 bytes.
Roving analysis is not supported on a system that has an ATM module
installed in the chassis.
Remote roving analysis is not supported over a Fast Ethernet
connection that has the Spanning Tree Protocol enabled.
Before you enable Express Switching mode, disable the backbone
port. Then, after you enable Express Switching mode, reenable the
backbone port.
The system cannot route FDDI multicast frames that are larger than
1500 bytes (that is, frames that require fragmentation).
The FCS error statistics field reports inaccurate values for Fast Ethernet
ports.
