RSTP status information:
click RSTP current status button to check
RSTP status information.
At this time, the information on the page shows the current status of RSTP.
RSTP is always in the process of dynamic detection and negotiation. Therefore,
every time you refresh this page, you will see the latest status. Each time you
refresh this page, the information is different.
Forwarding status
: it has four kinds:
Disabled
: this means port do not connect.
Discarding
: in this status could receive BPDU data package, if this period
not receive BPDU then change to learning state, when link just connect to ports
will in discarding state.
Learning
: in learning status, you can receive the data packet, immediately
connected to the switch in the blocking state when the stay max ageing time =
20s time to determine the switch port it is possible to become a root port or
designated port, during the send and receive BPDU packets to complete the
generation root of the tree of the election, construction, completion port status
whereabouts of the decision. If the decision is the root port or designated port,
then it stays forward delay (= 15s) time, and continue to the port can not be
calculated to determine the root port or designated port, this time with learning
MAC addresses. If it is the root port or designated port to the forwarding state
after the conversion, if not, then switch to blocking status.
Forwarding: forwarding status, then the normal port can send and receive
packets.
To speed up the healing process RSTP to reduce network load, the user
can use the following page details the configuration port information:
Port role
: There are five types of roles for labeling ports.
Root
: The port that receives the configuration packet sent by the root
bridge periodically. That is, the root bridge is the only device in the entire
network that does not have a root port. The alternate port is its standby port,
but is blocked because it receives better configuration packets from other
switches.
Unknown
: Not when any of the above ports.
Forwarding status
: refers to the running status of the port, there are four
types:
