10 COREBUILDER 2500 INTELLIGENT SWITCHING SOFTWARE VERSION 8.1.2
System Issues The following system issues have been identified for software
version 8.1.2:
■When a ping is initiated from the CoreBuilder 2500 syst em 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 f or 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
CoreBuilder7000 switch, it could take several minutes for a LEC
configured on a CoreBuilder 2500 to join an e mulated LAN.
■Packet filters can access data only through byte 6 4 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 syst em 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 fra gmentation).
■The FCS error statistics field reports inaccurate values for Fast Ethernet
ports.
