2. Usage:
Use this command to specify the maximum allowed hops for BPDU in an MST region. This parameter
is used by all the instances of the MST. Specifying the max hops for a BPDU prevents the messages
from looping indefinetely in the network. When a bridge receives a MST BPDU that has exceeded the
allowed max-hops, it discards the BPDU.
3.
Command Syntax:
bridge GROUP max-hops HOP_COUNT
no bridge GROUP max-hops
GROUP <1-1> Specify the bridge-group ID.
HOP_COUNT Maximum hops the BPDU will be valid for.
4.
Example:
The following example specifies the maximum allowed hops ( 25 ) for BPDU in bridge GROUP ( 1 ):
switch_a(config)#bridge 1 max-hops 25
switch_a(config)#
MSTP INSTANCE SETTING
Bridge Instance VLAN:
1.
Command Mode: MST Configuration mode
Logon to Configure Mode (Configure Terminal Mode).
Then logon to MST Configuration mode.
The
switch_a(config-mst)# prompt will show on the screen.
switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#
2.
Usage:
Use this command to simultaneously add multiple VLANs for the corresponding instance of a bridge.
This command can be used only after the VLANs are defined. Use the no parameter with this command
to simultaneously remove multiple VLANs for the corresponding instance of a bridge.
3.
Command Syntax:
bridge GROUP instance INSTANCE_ID vlan VLAN_ID
no bridge GROUP instance INSTANCE_ID vlan VLAN_ID
GROUP <1-1> Specify the bridge-group ID.
INSTANCE_ID <1-15> Specify the instance ID.
VLAN_ID <1-4094> Specify multiple VLAN IDs corresponding to the bridge instance
4.
Example:
The following example associates multiple VLANs (
10
) and (
20
) to instance (
1
) of bridge GROUP (
1
):
switch_a(config)#bridge 1 protocol mstp
switch_a(config)#spanning-tree mst configuration
switch_a(config-mst)#bridge 1 instance 1 vlan 10, 20
switch_a(config-mst)#
Bridge Instance Priority:
1.
Command Mode: Configure mode
Logon to Configure Mode (Configure Terminal Mode).
The
switch_a(config)# prompt will show on the screen.
switch_a(config)#
