10COREBUILDER 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 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.
