  • Configure the type of ports that will be connected to nodes as nni.
  • Disable the STP on ports that will be connected to nodes.
  • Configure the mode of ports that will be connected to nodes as trunk.
  • Add the ports that will be connected to nodes to the control VLAN that the node belongs to.

Description

Enter the global configuration mode

configure terminal

-

Configure edge assistant node

eips ring ring-id assistant [ segment ]

Mandatory

By default, the edge assistant node is not configured,

It is recommended that the segment parameter be used to specify the EIPS ring in the hierarchical mode.

Otherwise, the EIPS ring is in the sub ring mode.

Associate the edge assistant node to the transmission node

transit ring ring-id

Mandatory

By default, the edge assistant node is not associated to the transmission node.

Only when the edge assistant node is associated to the transmission node, the low-level segment or sub ring can coordinate with the main ring.

Configure the edge port on the edge assistant node

edge interface interface-name

Mandatory

By default, the edge port on the edge assistant node is not configured.

The edge port connects a low-level segment or sub ring to the main ring.

Configure the data instance for the edge assistant node

instance instance-id

Mandatory

By default, the data instance for the edge assistant node is not configured.

The data VLANs that are allowed to pass on the EIPS port must be contained in the EIPS data instance. The same data instance must be configured on all the nodes in the same EIPS domain.

Configure EIPS Domain

The EIPS domain specifies the domain that the EIPS ring or the level segment belongs to. All nodes in the same EIPS domain must be configured with the same domain ID.

Table 3–6 Configure EIPS domain

Step

Command

Description

Enter the global configuration mode

configure terminal

-

Enter the EIPS configuration mode

eips ring ring-id { master | transit | edge | assistant   } [ segment ]

-

Configure the EIPS domain

domain id domain-id

Mandatory

By default, the EIPS domain is not configured.

Configure EIPS Control VLAN

Configure the control VLAN for an EIPS ring or the level segment before starting the EIPS protocol. All nodes on the same EIPS ring must be configured with the same control VLAN. Therefore, when configuring the control VLAN, choose the VLAN that has been created but not used by other L2 protocols. Otherwise, the configuration fails. The EIPS control VLAN transfers EIPS protocol packets instead of data packets.

Step

Command

Description

Enter the global configuration mode

configure terminal

-

Configure EIPS Level Number

The EIPS level number is an important symbol to distinguish the main ring from the sub ring or low-level segment. The level number of all the main rings is 0 and the level number of level-1 sub ring or the level-1 level segment is 1. The rest can be done in the same manner. All the nodes on the sub rings must be configured and the sub ring number of the same level or the level number of the same level segment must be the same.

level level-id

Mandatory

By default, the level number for the sub ring or the level segment is not configured.

Configure EIPS Segment Number

The EIPS segment number is an important symbol in the hierarchical mode. The segment number of the main ring is 0 and the segment number on the low-level segment is defined by the user. The segment number must be configured for the level segment with level number greater than 0. Meanwhile, the segment number for the nodes on the same level segment must be the same.

This command is dedicated to the EIPS hierarchical mode and is not available for the sub ring mode. The segment number is configured on the edge control node, transmission assistant node, and transmission node for the low-level segment.

Configure EIPS Data Instance

The data instance must be configured before configuring the EIPS ring or the level segment. The data VLANs that are allowed to pass on the EIPS port must be contained in the EIPS data instance. The same data instance must be configured on all the nodes in the same EIPS domain.

The data instance is configured by using the MSTP (Multiple Spanning Tree Protocol Instance). Therefore, before configuring the EIPS ring or the level segment, configure the MSTP instance and the mapping relationship between the MSTP and the VLAN contained in the MATP.
