MSTI.
Hello Time:
1 / 2
In contrast with RSTP, Hello Time in MSTP is a per port setting for the
CIST.
Admin Edge:
Yes / No
The same definition as in the RSTP specification for the CIST ports.
Admin P2P:
Auto / True / False
The same definition as in the RSTP specification for the CIST ports.
Restricted Role:
Yes / No
If “Yes” causes the Port not to be selected as Root Port for the CIST or
any MSTI, even it has the best spanning tree priority vector. Such a Port
will be selected as an Alternate Port after the Root Port has been
selected. This parameter is “No” by default. If set, it can cause lack of
spanning tree connectivity. It is set by a network administrator to prevent
bridges external to a core region of the network influencing the spanning
tree active topology, possibly because those bridges are not under the
full control of the administrator.
Restricted TCN:
Yes / No
If “Yes” causes the Port not to propagate received topology change
notifications and topology changes to other Ports. This parameter is “No”
by default. If set it can cause temporary loss of connectivity after
changes in a spanning trees active topology as a result of persistent
incorrectly learned station location information. It is set by a network
administrator to prevent bridges external to a core region of the network,
causing address flushing in that region, possibly because those bridges
are not under the full control of the administrator. or the status of MAC
operation for the attached LANs transitions frequently.
Mcheck:
The same definition as in the RSTP specification for the CIST ports.
