The following example displays port mirroring information for the G450:
G450-001(super)# show port mirror
port mirroring
Mirroring both Rx and Tx packets from port 10/5 to port 010/6 is enabled
The following example disables port mirroring:
G450-001(super)# clear port mirror

Configuring spanning tree

G450 devices support the enhanced Rapid Spanning Tree Protocol (802.1w). The 802.1w
standard is a faster and more sophisticated version of the 802.1d (STP) standard, and includes
backward compatibility with 802.1d. Spanning tree makes it possible to recover connectivity
after an outage within approximately a minute. RSTP, with its "rapid" algorithm, can usually
restore connectivity to a network where a backbone link has failed in much less time.

Spanning tree protocol

The spanning tree algorithm ensures the existence of a loop-free topology in networks that
contain parallel bridges. A loop occurs when there are alternate routes between hosts. If there is
a loop in an extended network, bridges may forward traffic indefinitely, which can result in
increased traffic and degradation in network performance.
