Root bridge
A single Bridge is selected to become the Spanning tree’s unique root bridge. This is the
device that advertises the lowest Bridge ID. Each bridge is uniquely identified by its Bridge
ID, which comprises the bridge’s root priority (a spanning tree parameter) followed by its
MAC address.
For an overview of spanning tree operation see “Spanning tree operation” on
page 18.2 .
Root path cost
A Spanning tree property. Each port connecting a Bridge to a LAN has an associated cost,
called the root path cost. This is the sum of the costs for each path between the particular
bridge port and the
Root bridge . The Designated bridge for a LAN is the one that
advertises the lowest root path cost. If two bridges on the same LAN have the same lowest
root path cost, then the switch with the lowest bridge ID becomes the designated bridge.
For an overview of spanning tree operation see “Spanning tree operation” on
page 18.2 .
Route-map
A mechanism for filtering IP routes and changing their attributes.
RSTP
Rapid Spanning Tree Protocol. RSTP is an evolution of the Spanning Tree Protocol ( STP )
which provides for faster spanning tree convergence after a topology change. A device
running RSTP is compatible with other devices running STP.
For more information see “Rapid Spanning Tree Protocol (RSTP)” on page 18.8 . For a
configuration example see “Configuring RSTP” on page 18.9 .
S
SCP
Secure Copy Protocol. SCP allows for secure file transfer to and from the switch, protecting
your network from unwanted downloads and unauthorized file copying.
For more information see “Copying with Secure Copy (SCP)” on page 6.17 .
Script
A script is a sequence of commands stored as a plaintext file on a file subsystem accessible
to the device, such as Flash memory. Each
Trigger may reference multiple scripts and any
script may be used by any trigger. When an event activates a trigger, the trigger executes
the scripts associated with it in sequence. One script is executed completely before the
next script begins.
