priority priority-value: Specifies the priority of the line clock source. It ranges from 1 to 2, and defaults to 1. The value 2 has a higher priority over the value 1.

Description

Use the clock-source command to configure clock source.

Use the undo clock-source command to restore the default setting.

By default, the clock source mode is master.

Note that the slave clock source mode can be configured for the two ports of a link, but the two sources must have different priorities.

Examples

# Configure the clock source mode as master.

<H3C> system-view

[H3C] interface RprPos2/1/1.1

[H3C-RprPos2/1/1.1] clock-source master

# Configure the clock source mode as slave, and set the priority of the clock source to 2.

View

Any view

Parameters

interface-type: Port type.

interface-number: Port number.

packets: Displays the statistics on the packets passing through the port.

Description

Use the display interface command to display the RPR port configuration and status information.

l If you specify neither port type nor port number, the command displays the information about all ports on the switch.

l If you only specify a port type, the command displays the information about all ports of the specified type.

l If you specify a port type and a port number, the command displays the information about the specified port.

When displaying information about RPR ports:

l If you do not specify a port number, the command displays all port information, including the status information about RPRPOS logical interfaces and physical ports.

l If you specify a port number, the command displays the information about the specified port.

By viewing the information about physical ports, you can monitor the SDH physical layer and performance. For example, you can monitor basic alarms such as out of frame (OOF), loss of frame (LOF).

1.1.4 display rpr counters

Syntax

display rpr counters [ transit | host | total ] [ { RprPos | Rpr10GE | RprGE } interface-number ]

View

Any view

Parameters

transit: Traffic transited by the station.

host: Host traffic through the station.

total: Total traffic through the station.

RprPos: Specifies the interface type RPRPOS.

Rpr10GE: Specifies the interface type RPR10GE.

RprGE: Specifies the interface type RPRGE.

interface-number: Interface number.

Description

Use the display rpr counters command to display the statistics of different types of packets sent, received, and forwarded through the specified station.

The statistics includes packets sent and received on the hosts and interfaces of the current station, packets transited by the station, average rate in the latest specific time period, and the error packets received on the interface.

The statistics displays information about unicasts and multicasts of four priorities (A, B0, B1, and C) inserted, copied, and transited by the station.

Statistics of the transited packets are calculated as follows: the east transited packets are packets transited by ringlet 0; the west transited packets are packets transited by ringlet 1. The command output displays the east and west span statistics by physical port. For example, RPRPOS 1/1/1.1 specifies the west span and RPRPOS 1/1/1.2 specifies the east span.

l If the traffic type is not specified, the command displays all the traffic statistics.

l If no RPR port is specified, the command displays traffic statistics of all the RPR ports.

l If an RPR logical interface is specified, traffic statistics of both west and east ports are displayed.

Example

# Display the traffic information of the RPR logical interface RPRPOS 1/1/1.

<H3C> display rpr counters RprPos1/1/1

RPR logical interface view

Parameters

fs: Forced switchover.

ms: Manual switchover.

idle: Clears forced switchover or manual switchover and enters Idle state.

ringlet0: Requests switchover in Ringlet0.

ringlet1: Requests switchover in Ringlet1.

Description

Use the rpr admin-request fs command to generate a forced switchover request, making the station enter forced switchover status. The event related to switchover in protection mechanism includes FS, SF, SD, MS, WTR and IDLE. Other protection requests are not able to preempt FS with the highest priority. After you use the rpr admin-request fs command to generate an FS request, other events are not able to preempt FS. To cancel FS, you must use the rpr admin-request idle command.

Use the rpr admin-request ms command to generate an MS for manual switchover. The MS priority is lower. Both the rpr admin-request idle command and any failure (FS, SF or SD) in the RPR ring can preempt MS, making MS fail. If there are other commands with higher priority, the manual switchover you are performing also fails automatically.

Use the rpr admin-request idle command to clear forced switchover or manual switchover.

Note that:

l The receiving and sending sub-rings of port 1 on the panel are Ringlet0 and Ringlet1 respectively. The receiving and sending sub-rings of port 2 on the panel are Ringlet1 and Ringlet0 respectively. Here Ringlet0 and Ringlet1 are both receiving sub-rings.

mac-address: MAC address of destination station.

ringlet0: Transports packets to the specified station over Ringlet0.

ringlet1: Transports packets to the specified station over Ringlet1.

Description

Use the rpr static-rs command to configure static ring selection information and force the RPR ring to transmit packets to the specified station. You can configure them according to the IP address or MAC address of the destination station.

Use the undo rpr static-rs command to remove the configuration. If no parameter is selected, the command removes all static configurations.

By default, the static ring selection information is not configured.

Note that two stations’ bridge MAC addresses cannot be the same on the ring. Here both Ringlet0 and Ringlet1 refer to sending sub-rings.

Examples

# Transport data packets to the destination station with MAC address 0016-E266-0101 over ringlet0, and transport data packets to the destination station with MAC address 0016-E266-0202 over ringlet1.

View

System view

Parameters

interface-type: Port type.

interface-number: Port number.

vlan-list: VLANs to be bound. You can specify separate VLANs or a VLAN range in the format of vlan-list = { vlanid [ to vlanid ] }&<1-9>. &<1-9> means that you can provide up to nine separate VLANs or VLAN ranges.

trigger-shutdown: Specifies to shut down the ports bound to a BAS port when the latter goes down. If you specify this keyword, the ports specified are shut down automatically when the BAS port bound goes down. Otherwise, you need to shut down the ports manually.

Description

Use the rpr tunnel track command to bind the port connected with a BAS and specified RPR ports and specify the related VLANs. Use the undo rpr tunnel track command to remove the corresponding configuration.

When a BAS port goes down/up, the RPR ports bound to it release a VLAN reachable/unreachable message to notify the entire network, by which the related RPR stations decide whether or not to switch Layer 2 tunnels. By specifying the trigger-shutdown keyword, you can have the BAS port automatically shut down when the status of specific RPR ports change to trigger port switching on the uplink BAS device.

Chapter 3 VRRP over RPR Collaboration Group Configuration Commands

3.1 VRRP over RPR Collaboration Group Configuration Commands

3.1.1 display rpr vrrp

Syntax

display rpr vrrp [ interface-type interface-number ] [ group group-id ]

View

Any view

Parameters

interface-type: RPR logical interface type.

interface-number: RPR port number.

group-id: VRRP group ID, in the range 1 to 2.

Description

Use the display rpr vrrp group command to display the information about a VRRP group to which an RPR port is bound.

You can provide the logical RPR interface or the VRRP group, or both, for the command. When displaying collaboration group information, the system does not check whether or not the VLAN and VRID of the elaboration group exist in the system. If you do not specify a group ID, this command displays the information about all the groups on the port. If neither of the group number and RPR port number is provided, the command displays the information about all the collaboration groups configured in the system. If the VRRP group bound with the queried collaboration group is not configured, the system only displays the configuration information of the collaboration group.

Examples

# Display the information about the VRRP collaboration group 2 in RPR logical interface RPRPOS 4/1/1 with enabled VRID 1.

<H3C> display rpr vrrp RprPos4/1/1 group 2

Group ID : 2

3.1.2 rpr vrrp

Syntax

rpr vrrp vlan vlan-id vrid vrid-id [ mate h-h-h ] group group-id

View

RPR logical interface view

Parameters

vlan-id: ID of the VLAN to be bound. It ranges from 1 to 4094 and can be in any group with the allowed VLAN specifications.

vrid-id: VRRP VRID group to be bound. It ranges from 1 to 255 and can be in any group with the allowed VLAN specifications.

mate h-h-h: MAC address of the adjacent station. It indicates whether fast switching is required for the current collaboration group. If you select this argument, the system will compare the received attribute discovery (ATD) frame with the configured MAC address. If they match each other, the system will resolve the frame, and switch the collaboration group according to the priorities.

group-id: Group ID in the range of 1 to 2.

Description

Use the rpr vrrp command to bind a VRRP VRID in a VLAN to an RPR logical interface, and specify whether fast switching is required.

When you configure a collaboration group, the system does not check whether the specified VLAN and VRID exist or not. A collaboration group takes effect only when the VLAN and VRID exist. The MAC address of the adjacent station needs to be configured by users. Based on the protocol frame of the matched MAC address, the collaboration group decides whether to perform fast switching. The system does not check whether the configured MAC address of the adjacent station is an address in the RPR. Instead, users must make appropriate configurations themselves. Each RPR logical interface can only be configured with two VRRP over RPR collaboration groups.

Examples

# Add a VRRP collaboration group to the RPR logical interface RPRPOS 4/1/1, binding VRID 20 in VLAN 10 to RPRPOS 4/1/1 (the MAC address of the adjacent station is 000F-E211-1B16).
