Lucent Technologies P550R, P220 manual File Naming Standard for Embedded Nvram File System

For ports that have a 3Com trunking format, the receiving end of the trunked port attempts to interpret the clear BPDUs as trunked packets. Consequently, these BPDUs are discarded at the receiving end. For Spanning Tree to function properly with 3Com trunked ports, the Spanning Tree mode should be set to per-VLAN. In per-VLAN Spanning Tree, there is one instance of Spanning Tree for each VLAN and the BPDUs are tagged with the VLAN ID, ensuring they are interpreted correctly on the receiving end.

NOTE: Although this restriction does not apply to ports that use IEEE 802.1Q or Multi- Layer trunking modes, it is still recommended that you set Spanning Tree to per-VLAN when using trunked ports. This prevents an entire link from being blocked when there is a loop in one VLAN.

NOTE: All NVRAM files must use an 8.3 format for file names.

When downloading code to the NVRAM file system, use standard 8.3 file naming conventions (the default download file names do not use this convention).
