Attention:
1. The RSTP protocol is defined in the 802.1w standard and is an open
standard protocol. The RSTP protocol of the switch produced by the
company can be compatible with network devices that are not produced by
the company but support the standard RSTP protocol.
2. The fast spanning tree and fast ring network functions cannot be
enabled at the same time. If RSTP is enabled, the fast ring network will be
automatically turned off. Similarly, if fast ring network is enabled, RSTP will
be automatically disabled.
3. When RSTP is enabled, RSTP will disable all ports first. After the
convergence period is completed, certain ports will be enabled and blocked.
During this period, the web server will lose response. When convergence
ends (about 10s or more), the network tree Once generated, you can re-use
the web server;
4. Every time the link is changed, RSTP will re-converge with a different
time, but it may also cause the Web server to be inaccessible. After the
convergence is over, it can be re-accessed.
5. After RSTP is enabled, each switch periodically sends a query packet
from each connection port according to the interval of sending packets set by
the user, thus increasing the network load;
6. The following conditions must be met between the maximum aging
time and the forwarding delay: 2* (forward delay-1) ≥ maximum aging time;
7. In order to reduce the network computing complexity and reduce the
convergence time, you are advised to set the port information, reduce the
number of ports, reduce the forwarding delay, and maximize the aging time
to speed up the self-healing of RSTP.
8. When the quick spanning tree is enabled, check the Ethernet Control
Packet and Address Query Failure Packet on the storm suppression
interface. (The storm suppression defaults these two items are also
checked).
4.7. Equipment management
The device management includes: network address, user password,
system information, and system management.
4.7.1. Network address
The function of this function is to assign a specified IP address to the
switch. The default IP address of the switch when it leaves the factory is
192.168.16.253.
