TFTP File Cache

The TFTP cache feature allows copies of frequently requested files to be

temporarily stored on the BSGX4e. If a file requested by a LAN device is found in the

cache, it can be immediately sent to the client.

File caching provides the following benefits:

 Avoids unnecessary WAN bandwidth usage for frequently requested files,

especially if several user devices exist, such as VoIP phones

 Improves scalability of VoIP service from a service provider, by reducing load on

the central file servers that are used for provisioning user devices

NOTE: The TFTP relay function must be enabled.

TFTP Cache Command

For a TFTP file cache, enter the following command:

> config relay tftp cache

Table 96 describes the parameters for config relay tftp cache.
