Parameter Description Default See page...
IP state The Internet Protocol, version 4 Enabled
Note: You cannot
disable IP.
n/a
IP address A Layer 3 network interface address
Note: Layer 2 Switches have a single IP address
used for management access to the entire device.
Layer 3 Switches have separate IP addresses on
individual interfaces.

Encapsulation
type
The format of the packets in which the router
encapsulates IP datagrams. The encapsulation
format can be one of the following:
• Ethernet II
•SNAP
Ethernet II 16-21
Maximum
Transmission
Unit (MTU)
The maximum length (number of bytes) of an
encapsulated IP datagram the router can forward.

on the interface. This parameter applies only to RIP
routes.

DHCP gateway
stamp
The router can assist DHCP/BootP Discovery packets
from one sub-net to reach DHCP/BootP servers on a
different sub-net by placing the IP address of the
router interface that receives the request in the
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.

IP address on the
interface that receives
the request
