monitor capture (interface/control plane)
To configure monitor capture points specifying an attachment point and the packet flow direction or add more
attachment points to a capture point, use the monitor capture command in privileged EXEC mode. To disable
the monitor capture with the specified attachment point and the packet flow direction or disable one of multiple
attachment points on a capture point, use the no form of this command.
monitor capture {capture-name}{interface interface-type interface-id | control-plane}{in | out | both}
no monitor capture {capture-name}{interface interface-type interface-id | control-plane}{in | out | both}

Usage Guidelines
Once an attachment point has been associated with a capture point using this command, the only way to change
its direction is to remove the attachment point using the no form of the command and reattach the attachment
point with the new direction. An attachment point's direction cannot be overridden.
If an attachment point is removed from a capture point and only one attachment point is associated with it,
the capture point is effectively deleted.
Multiple attachment points can be associated with a capture point by re-running this command with another
attachment point. An example is provided below.
Multiple capture points can be defined, but only one can be active at a time. In other words, you have to stop
one before you can start the other.
Packets captured in the output direction of an interface might not reflect the changes made by switch rewrite
(includes TTL, VLAN tag, CoS, checksum, MAC addresses, DSCP, precedent, UP, etc.).
