BOOTP

-

This enhancement enables you to associate a BOOTP relay destination with a

given interface. To do this, use the new optional interface parameter in the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

command:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

ADD BOOTp RELAy=ipadd INTerface=interface

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

BOOTP packets received on this interface are relayed to the specified relay

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

destination only. You can define the same interface for multiple relay

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

destinations; the router or switch relays any BOOTP packets received to each relay

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

destination.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

If you do not specify an interface, the destination becomes a “generic”

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

destination. If the router or switch receives a BOOTP message on an interface for

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

which no specific destination is defined, the router or switch relays the message

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

to all generic destinations. This is the same as the behaviour prior to this

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

enhancement.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To remove a destination that is associated with an interface, use the command:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

DELete BOOTp RELAy=ipadd INTerface=interface

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

To see the interfaces that each destination is associated with, use the pre-existing

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

command:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SHow BOOTp RELAy

DHCP

DHCP snooping records its client database into a file in NVS (if possible) or Flash

memory. In previous versions, that file was named bindings.dsn. From this

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

version, the file structure has changed and the file is now named bind0002.dsn.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

When you upgrade a switch to this version, the switch creates the new client

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

database file 10 seconds after initialising the new version. After that, you can

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

safely delete the old bindings.dns file, if desired.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Note that the functionality of DHCP snooping has not changed, only the

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

filename.
