The following example shows Cisco Express Forwarding interface events:
Router# show monitor event-trace cef interface all
00:00:24.624: <empty> (sw 4) Create new
00:00:24.624: <empty> (sw 4) SWIDBLnk FastEthernet0/0(4)
00:00:24.624: Fa0/0 (sw 4) NameSet
00:00:24.624: <empty> (hw 1) Create new
00:00:24.624: <empty> (hw 1) HWIDBLnk FastEthernet0/0(1)

Cisco Express Forwarding Component Examples for Cisco 10000 Series Routers Only

The following example shows the IPv4 events related to the Cisco Express Forwarding component. Each trace message is numbered and is followed by a time stamp (derived from the device uptime). Following the time stamp is the component-specific message data.
Router# show monitor event-trace cef ipv4 all
00:00:48.244: [Default] 127.0.0.81/32'01 FIB insert [OK]
