Bridge Settings

S4224 STP Bridge configuration is done from the

Configuration >

Spanning Tree

Bridge Settings

menu path.

This page lets you configure STP system settings, which are used by all S4224 STP Bridge instances.

Basic Settings

Protocol Version

The STP protocol version setting. Valid values are

STP

RSTP

and

MSTP

. The default is

MSTP

: MSTP (Multiple Spanning Tree Protocol) is an evolution of RSTP. The MSTP protocol

provides for multiple spanning tree instances, while ensuring RSTP and STP compatibility. The IEEE

802.1Q-2005 standard, section 13 discusses MSTP. For MSTP details see

http://standards.ieee.org/getieee802/download/802.1Q-2005.pdf

. MSTP works over VLAN instances,

and multiple VLANs can be added to an MSTI; however, at any time a VLAN can only be part of one

MSTI. Configuration for each MSTI and the VLANs that belong to that instance is supported. The

S4224 also supports configuration of enabling/disabling BPDU guard, path cost for that port,

restricting topology change notification, etc. Note that MSTP is disabled on the S4224 MGMT/data

port.

RSTP

IEEE with document 802.1w introduced an evolution of STP: the Rapid Spanning Tree

Protocol, which provides for faster spanning tree convergence after a topology change. The IEEE

802.1D-2004 standard now incorporates RSTP and obsoletes STP, while at the same time being

backwards-compatible with STP. The IEEE 802.1D-2004 standard, section 17 discusses RSTP.

See

http://standards.ieee.org/getieee802/download/8021D-2004.pdf

RSTP switch port states include

Discarding (no user data is sent over the port), Learning (the port is not forwarding frames yet, but is

populating its MAC-address-table), and Forwarding (the port is fully operational).

STP

: Spanning Tree Protocol (STP) is an OSI layer-2 protocol that ensures a loop free topology for

any bridged LAN. The original STP protocol is now obsolete by RSTP.
