Cisco Systems OL-11291-01 Manual De Usuario

The DHCP operation measures the round-trip latency time taken to discover a DHCP server and obtain 
a lease from it. After obtaining an IP address, SA Agent releases the IP address that was leased by the 
server. By default, the DHCP operation sends discovery packets on every available IP interface on the 
source router. 

However, if a specific DHCP server is configured on the router, then discovery packets are sent to only 
that DHCP server. The DHCP operation also measures availability and errors for DHCP services.

To measure end-to-end performance for DHCP:

Define a device as the source device from which to measure performance. For details on defining a 
source device, see 

To control how statistics are collected, use the DefaultDHCP operation or define your own DHCP 
operation. For details on defining a DHCP operation, see 

.

Define a collector to measure performance between the source router and the DHCP servers. For details 
on defining a collector, see 

.If you set the collector’s schedule to On Demand, start 

the collector when needed.

View the statistics in the DHCP Historical Statistics window. For details on viewing statistics for DHCP, 
see 

IPM provides a default DHCP operation for measuring performance in leasing an IP address from a 
DHCP server. In addition, IPM provides the option to create, modify, or delete your own DHCP 
operations from the DHCP Operation Configuration window.

To define a DHCP operation:

From the IPM Main Window, select Edit > Configuration. 

The Configuration window appears.

Click Operation.

The Operation Configuration window appears within the Configuration window.

Click DHCP.
