Ring
N-Ring Manager, Auto Member, and Multi Member cannot be enabled on BR port sets. N-Ring port sets exclude
BR-capable ports.
RSTP
RSTP is disabled on BR ports to prevent unacceptable performance within an RSTP topology.
IGMP
Caution must be taken when IGMP is enabled. Devices connected to BR ports must be able to accommodate
higher traffic rates. Test your network conditions with the BR switch both powered on and off if IGMP is to be
enabled on a BR port.

Properties
Port
Trunking
BR port pairs cannot be members of the same trunk group to prevent a network loop being created in bypass
mode.
VLAN
VLAN group membership must be identical between BR port pairs to ensure proper flow of traffic when the switch
enters bypass mode. Caution must also be taken when modifying VLAN tags or filtering VLAN traffic on BR ports to
ensure that all devices connected to BR ports can accommodate VLAN traffic whether the BR switch is powered on
or powered off.
Note:
The VLAN(s) associated with RSTP may contain BR ports, however RSTP will be disabled on the BR
ports.
Port
Compatibility
Care should be taken to ensure port characteristics of devices connected via BR ports are compatible, so that there
are no interruptions in traffic when a BR switch enters bypass mode.
