What is DHCP?
DHCP (Dynamic Host Configuration Protocol) allows clients to obtain LAN
parameters automatically from a server.
How does the emulation probe use DHCP?
The trace port analyzer uses "static allocation" (sometimes called "manual
allocation") to obtain a permanent IP address. Every time the trace port
analyzer is turned on, it sends out a BOOTP request packet. If the DHCP
server on the network responds to BOOTP requests and has been configured
to reply to the trace port analyzer's link-level address, it will respond with the
IP address and other LAN parameters.
The trace port analyzer does not support "automatic allocation", which
permanently allocates IP addresses from a pool of addresses.
Nor does the trace port analyzer support "dynamic allocation" of IP
addresses—it does not track lease duration and request a new IP address
when the lease is about to expire.
How does DHCP interact with other methods of
setting LAN parameters?
Every time the trace port analyzer is turned ON, it sends out a BOOTP request
packet (even if the LAN parameters have already been configured). As long as
the DHCP server is configured to reply to BOOTP requests from the trace port
analyzer's link-level address, it will respond with the IP address and other LAN
parameters.
To configure LAN parameters using a logic analysis
system without an emulation module
1 Connect the LAN cable to the connector on the emulation probe.
2 In the logic analysis system interface, open the Workspace window.
3 Drag the emulation probe tool from the toolbox to the workspace.
4 From the emulation probe icon, select ,QLW 3UREH /$1 $GGUHVVHV .
