MIEN5208 Series Managed Industrial Ethernet Switch
- 21 -
Ring port 1:
Join the first port of the ring group.
Ring 2:
Join the second port of the ring group.
Ring network type: T
he type of the ring network group, which is usually a
single ring network.
Enable:
Enable the ring group, usually enable the entire ring function first,
and then enable the required ring group. If the ring group enable option is not
checked, the ring group is turned off even if the ring function is enabled.
Attention:
1.Mwring belongs to the company's private ring network protocol and
can only be used in the same series of switches of the company. It is not
compatible with switches other than the company;
2. When the fast ring is enabled, all switches have a short time to quickly
exchange packets to block redundant links, and then the ring will be in a
transient state; once the primary link is disconnected, There is also a short
time between the switches to quickly exchange data packets to enable the
blocked redundant links to achieve self-healing purposes, and then the ring
network will be in another transient state, in this state transition There will be
packet loss, but the time will be very short (<20ms);
3. It is recommended that the user enable the number of ring network
groups as little as possible. If a single ring is enabled, multiple single rings
should not be enabled to avoid increasing the complexity of the network link.
4. The self-healing time of the ring network is related to the number of
switches in the ring and the complexity of the ring network. The self-healing
time less than 20 ms is measured when four switches form a single ring.
5.Note that when Mwring is enabled, do not use port mirroring and port
speed limit for ports participating in the ring.
4.6.4. Multicast configuration
The switch provides the function of manually adding or deleting static
multicast MAC address forwarding entries.
The entry for this function is defined as static in the multicast table, and the
MAC address must be a multicast address. A static multicast MAC address
fulfills the forwarding function, but it is not subject to aging processing. Packets
whose destination address contains a static multicast MAC address will be
forwarded to the specified port. The switch supports up to 32 multicast
forwarding entries. The parameters are as follows:
MAC address: Enter the multicast MAC address to be added in this box.
The format is XX-XX-XX-XX-XX-XX. The first three bytes of the multicast
address are hexadecimal 01-00-5E. .
