Stp Configurable Parameters At The Port Or Lag Level - Brocade Communications Systems Brocade BladeSystem 4/24 User Manual

STP configurable parameters at the port or LAG level

You cannot configure Spanning Tree Protocol (STP) when adding a new LAG. STP can be configured
only after the LAG has been added to the switch.
Figure 125
LAG level.
The ports and the ports in a link aggregation group (LAG) for the selected switch must be in Layer 2
(L2) mode. If the ports or ports in a LAG are not in L2 mode, a yellow banner displays, indicating
Spanning Tree Protocol is disabled and the STP parameters are disabled as well.
NOTE
STP is not supported for internal ports on the 10 Gbps CEE/FC switch module. If an internal port is
selected, the Edit Port dialog box and Spanning Tree Protocol tab do not display, and the L3 interface
mode is unavailable.
