When you select Cisco Express Forwarding as the component for which to enable event tracing, you can
use the following additional arguments and keywords: monitor event-trace cef [events | interface | ipv6
| ipv4][all]. The following example shows how to enable event tracing for IPv4 or IPv6 events of the
Cisco Express Forwarding component in Cisco
IOS software:
configure terminal
!
monitor event-trace cef ipv4 enable
configure terminal
!
monitor event-trace cef ipv6 enable
exit
The following example shows what happens when you try to enable event tracing for a
component (in this case, adjacency events) when it is already enabled:
configure terminal
!
monitor event-trace adjacency enable
%EVENT_TRACE-6-ENABLE: Trace already enabled.
