9.4.9 Configure spanning-tree mst root-guard
Configure spanning-tree root-guard can avoid interface to be root which is used for preventing
bone network topology destroying by outer BPDU packet. Configure it in interface
configuration mode:
configure spanning-tree mst root-guard
spanning-tree mst root-guard
restore to default root-guard
no spanning-tree mst root-guard
Example:
! Enable mst root-guard of e0/1
QTECH(config-if-ethernet-0/1)#spanning-tree mst root-guard
9.4.10 Display MSTP configuration information
The basic information of MSTP includes: MSTP configuration mark information (includes
configuration name, modify level and the mapping relations between vlan and MSTP instance);
the configuration information of STP instance and interface.
Use this command in any configuration mode:
Display MSTP configuration mark information
show spanning-tree mst config-id
Display interface information of some instance
show spanning-tree mst instance instance-num interface [ interface-list ]
! Example:
Display MSTP configuration mark information
QTECH(config)#show spanning-tree mst config-id
Display information of interface 2 in instance 1
QTECH(config)#show spanning-tree mst instance 1 interface ethernet 0/0/2
9.4.11 Enable/disable digest snooping
When interface of switch connects to switch which has its own private STP, switch cannot
connect to each other because of the private STP protocol. Digest snooping can avoid it.
Enable digest snooping, switch will think the BPDU packet from other switch is from the same
MST region and it will keep the configuring notes and add the notes to the BPDU packet to be
sent. Switch realizes interconnection with others in MSTP.
Configure it in interface configuration mode:
Enable interface digest-snooping
spanning-tree mst config-digest-snooping
Disable interface digest-snooping
no spanning-tree mst config-digest-snooping
Example:
! Enable digest-snooping of interface 0/1
QTECH(config-if-ethernet-0/1)# spanning-tree mst config-digest-snooping
9.4.12 Configure Ignore of VLAN
In order to control MSTP, Ignore of VLAN can be enabled and the corresponded interface will
not calculate.
Configure it in global configuration mode:
