VLAN is established, the IP address of the VLAN port cannot be pinged through
other devices.
The VLANs except the control VLAN are all data VLANs, which are used to transmit the packets of normal
services or the management packets.
The data VLAN can be used for normal L2/L3 communication. For example, you
can establish a VLAN port corresponding to data VLAN and configure dynamic
routing protocols.
26.1.2.4 Aging of the MAC Address Table
The Ethernet ring protection protocol can transmit data packets to the correct link by controlling the aging of
the switch’s MAC address table when the topology changes. In general, the time for a MAC address to age in
the MAC address table is 300 seconds. The ring protection protocol can control the aging of the MAC address
table in a short time.
26.1.2.5 Symbol of a Complete Ring Network
Both the master node and the transit node can show whether the current ring network is complete through the
state symbol “COMPLETE”. On the master node, only when all links of the ring network are normal, the
primary port is in forwarding state and the secondary port is in blocking state can the "COMPLETE” symbol be
real; on the transit node, only when its two transit ports are in forwarding state can the “COMPLETE” symbol
be true.
The state symbol of the ring network helps user to judge the topology state of the current network.
26.1.3 Types of EAPS Packets
The EAPS packets can be classified into the following types, as shown in table 1.1.
Table 1.1 Types of EAPS packets
Type of the packet Remarks
Loopback detection
（HEALTH）
It is transmitted by the master node to detect whether the
topology of the ring network is complete.
LINK-DOWN Indicates that link interruption happens in the ring. This
kinds of packets are transmitted by the transit node.
RING-DOWN-FLUSH-FDB It is transmitted by the master node after interruption of
the ring network is detected and the packets show the
MAC address aging table of the transit node.
RING-UP-FLUSH-FDB It is transmitted by the master node after interruption of
the ring network is resumed and the packets show the
MAC address aging table of the transit node.
