NOTE
The MSTP implementation is used to achieve load balancing by diverting traffic
associated with different VLANs to different links. However, when MSTP decides
on which port the traffic is to be sent (i.e., which port is forwarding) for a specific
MSTI (VLAN group) it
does not
take into account the VLAN membership of that
port. If the port is not a member of the VLAN, the traffic might not be forwarded.
It is recommended to match the VLAN configuration with the MSTP configuration
otherwise the traffic might not be forwarded properly.
The user should verify the consistency of VLAN to MSTI mapping and VLAN
membership scheme.
Configuring Global MSTP Parameters
Table 5
lists the MSTP global configuration commands.
Table 5: MSTP Configuration Commands
Command
Description
mstp
Enters the Protocol MSTP Configuration mode.
name
Defines the configuration name.
revision
Defines the configuration revision.
abort
Exits the configuration without saving the MST configuration map.
apply
Saves the MST configuration map and exits the configuration.
mstp hello-time
Sets the hello time.
mstp forward-delay
Sets the time for forward delay.
mstp max-age
Sets the maximum aging time.
mstp max-hops
Defines the max hop count.
mstp fast-ring ring
ports
Enables MSTP for accelerating its operation in ring topology.
mstp fast-ring
border-bridge
Enables the Ring Border Bridge functionality on a switch running
MSTP.
mstp learn-mode
Defines the mode in which the mac-addresses are learnt/flushed.
Enabling/Disabling MSTP
The
mstp
command, in Protocol Configuration mode, enters into Protocol MSTP Configuration
mode. When the
enable
argument is specified, MSTP will be enabled. To disable MSTP in
Protocol Configuration mode the
disable
argument must be specified.
By default, MSTP is disabled.
