Digisol DG-GS4528S - Stp Port Bpdutransparency

C HAPTER 16 | STP Commands
– 413 –
provides a secure response to invalid configurations because an
administrator must manually enable the port.
◆ If enabled, the port will disable itself upon receiving valid BPDU's.
Contrary to the similar bridge setting, the port Edge status does not
affect this setting. A port entering error-disabled state due to this
setting is subject to the bridge Port Error Recovery setting as well (see
the stp recovery command).
EXAMPLE
STP>port bpduguard 19 enable
STP>
stp port
bpdutransparency
This command displays or sets the BPDU transparency for specified ports.
SYNTAX

port-list - A specific port or range of ports. (Range: 1-28, or all)
enable - Enables BPDU transparency on the specified ports.
disable - BPDU transparency on the specified ports.

COMMAND USAGE
◆ BPDU transparency is commonly used to support BPDU tunneling,
passing BPDUs across a service provider’s network without any
changes, thereby combining remote network segments into a single
spanning tree. As implemented on this switch, BPDU transparency
allows a port which is not participating in the spanning tree (such as an
uplink port to the service provider’s network) to forward BPDU packets
to other ports instead of discarding these packets or attempting to
process them.
◆ Spanning tree mode must first be disabled on a port with the stp port
mode command before BPDU transparency can be enabled.
EXAMPLE
STP>port mode 19 disable
STP>port bpdutransparency 19 enable
