RMON Overview 83
■ Enable RMON statistics of Ethernet interface
1 Enable RMON statistics of Ethernet interface
After enabling RMON statistics of an Ethernet interface, the router will perform
the statistics of the packet incoming and outgoing through this interface. After
disabling it, the router will not perform the statistics of the packet incoming and
outgoing through this interface.
Perform the following task in Ethernet interface view.
Table 63 Enable RMON statistics of an Ethernet interface
RMON statistics is disabled by default.
This command cannot be used in Sub-interface view.
RMON Configuration
Examples
Enable RMON statistics
I. Networking Requirement
To ensure that the router can detect the packet whose destination is another
router from the Ethernet interface, the interface should be added in the DLSw
bridge set. Otherwise, the router only performs statistics for frames with this
router as the destination.
II. Networking Diagram:
Figure 37 Enable RMON statistics
III. Configuration Procedure
Configure the 3Com Router
1 Configure address and route of host1, host2, host3, routerA and routerB. Make
sure they can ping through each other. Specific operation is omitted here.
2 Add Ethernet interface Ethernet 0 to DLSw bridge set.
[RouterA] interface ethernet 0
[RouterA-Ethernet0] bridge-set 1
3 Enable RMON statistics of Ethernet 0
