Note: The HP 6208M-SX has a single IP address

 

 

 

used for management access to the entire device.

 

 

 

The routing switches have separate IP addresses on

 

 

 

individual interfaces.

 

 

 

 

 

 

Encapsulation

The format of the packets in which the router

type

encapsulates IP datagrams. The encapsulation

 

 

 

format can be one of the following:

 

 

 

•

Ethernet II

 

 

 

•

SNAP

 

 

 

 

 

 

Maximum

The maximum length (number of bytes) of an

The router can assist DHCP/BootP Discovery packets

request packet’s Gateway field.

 

 

 

You can override the default and specify the IP

 

 

 

address to use for the Gateway field in the packets.

 

 

 

Note: UDP broadcast forwarding for client DHCP/

 

 

 

BootP requests (bootpc) must be enabled and you

 

 

 

must configure an IP helper address (the server’s IP

 

 

 

address or a directed broadcast to the server’s sub­

 

 

 

net) on the port connected to the client.
