Monitor Link commands
display monitor-link group
Use display monitor-link group to display monitor link group information.
Syntax
display monitor-link group { group-id | all }
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
group-id: Specifies a monitor link group by its ID. The value range for the group-id argument is 1 to 16.
all: Specifies all monitor link groups.
Usage guidelines
This command does not display information about ports that belong to a link aggregation group.
Examples
# Display information about monitor link group 1.
<Sysname> display monitor-link group 1
Monitor link group 1 information:
Group status : UP
Downlink up-delay: 0(s)
Last-up-time : 16:38:26 2014/4/21
Last-down-time : 16:37:20 2014/4/21

Table 1 Command output
|
Field |
Description |
|
Monitor link group 1 information |
Information about monitor link group 1. |
|
Group status |
Monitor link group state, which can be up or down. |
|
Downlink up-delay |
Switchover delay of the downlink interfaces in the monitor link group, in seconds. |
|
Last-up-time |
Last time when the monitor link group was up. |
|
Last-down-time |
Last time when the monitor link group was down. |
|
Member |
Member interfaces of the monitor link group. |
|
Role |
Interface role, which can be uplink interface or downlink interface. |
|
Status |
Member link state, which can be up or down. |
downlink up-delay
Use downlink up-delay to configure the switchover delay for the downlink interfaces in a monitor link group.
Use undo downlink up-delay to restore the default.
Syntax
downlink up-delay delay
undo downlink up-delay
Default
The switchover delay for the downlink interfaces is 0 seconds. The downlink interfaces come up as soon as an uplink interface in the monitor link group comes up.
Views
Monitor link group view
Predefined user roles
network-admin
Parameters
delay: Specifies the switchover delay in the range of 1 to 300 seconds.
Usage guidelines
To avoid frequent state changes of downlink interfaces in the event that the uplink interfaces in the monitor link group flap, you can configure a switchover delay. After the switchover delay is configured, the downlink interfaces remain down until an uplink interface remains up for a period of time.
Examples
# Configure the switchover delay for the downlink interfaces in monitor link group 1 as 50 seconds.
<Sysname> system-view
[Sysname] monitor-link group 1
[Sysname-mtlk-group1] downlink up-delay 50
monitor-link disable
Use monitor-link disable to disable Monitor Link globally.
Use undo monitor-link disable to enable Monitor Link globally.
Syntax
Default
Monitor Link is enabled globally.
Views
System view
Predefined user roles
network-admin
Usage guidelines
All monitor link groups can operate only after you enable Monitor Link globally. When you disable Monitor Link globally, all monitor link groups cannot operate and the downlink interfaces brought down by the monitor link groups resume their original states.
Examples
# Disable Monitor Link globally.
[Sysname] monitor-link disable
monitor-link group
Use monitor-link group to create a monitor link group and enter monitor link group view.
Use undo monitor-link group to remove a monitor link group.
Syntax
monitor-link group group-id
undo monitor-link group group-id
Default
No monitor link group is created.
Views
System view
Predefined user roles
network-admin
Parameters
group-id: Specifies a monitor link group by its ID. The value range for the group-id argument is 1 to 16.
Examples
# Create monitor link group 1 and enter the view of monitor link group 1.
<Sysname> system-view
[Sysname] monitor-link group 1
[Sysname-mtlk-group1]
port
Use port to assign an interface to the monitor link group.
Use undo port to remove an interface from the monitor link group.
port interface-type { interface-number | interface-number.subnumber } { downlink | uplink }
undo port interface-type interface-number
Default
A monitor link group has no member interfaces.
Views
Monitor link group view
Predefined user roles
network-admin
Parameters
interface-type: Specifies an interface type, which can be Layer 2 Ethernet interface, Layer 3 Ethernet interface, Layer 3 Ethernet subinterface, Layer 2 aggregate interface, Layer 3 aggregate interface, Layer 3 aggregate subinterface, member port of a Layer 2 aggregation group or Layer 3 aggregation group, and S-channel interface.
interface-number: Specifies an interface by its number.
interface-number.subnumber: Specifies a subinterface by its number. The argument subnumber is in the range of 1 to 4094.
downlink: Specifies a downlink interface.
uplink: Specifies an uplink interface.
Usage guidelines
If you have configured an interface as the downlink interface of a monitor link group, do not configure its subinterfaces as the uplink interfaces of any monitor link group. Otherwise, the Monitor Link operation might be interrupted.
To avoid interrupting Monitor Link operation, do not assign the aggregate interface and member ports of an aggregate group to the same monitor link group.
The state of subinterfaces adapts to the state of the interface. Do not assign the interface and its subinterfaces to the same monitor link group. Otherwise, the monitor link group performance might be affected.
You can assign an interface to only one monitor link group.
You can also assign an interface to a monitor link group by using the port monitor-link group command in interface view.
Examples
# Configure FortyGigE 1/1/1 as an uplink interface and FortyGigE 1/1/2 as a downlink interface for monitor link group 1.
<Sysname> system-view
[Sysname] monitor-link group 1
[Sysname-mtlk-group1] port fortygige 1/1/1 uplink
[Sysname-mtlk-group1] port fortygige 1/1/2 downlink
port monitor-link group
port monitor-link group
Use port monitor-link group to assign the current interface to a monitor link group as a member interface.
Use undo port monitor-link group to remove the current interface from a monitor link group.
Syntax
port monitor-link group group-id { downlink | uplink }
undo port monitor-link group group-id
Default
The interface/subinterface is not a monitor link group member.
Views
Layer 2 Ethernet interface view
Layer 3 Ethernet interface/subinterface view
Layer 2 aggregate interface view
Layer 3 aggregate interface/subinterface view
Layer 2 aggregation group member port view
Layer 3 aggregation group member port view
S-channel interface view
Predefined user roles

Parameters
group-id: Specifies a monitor link group by it ID. The value range for the group-id argument is 1 to 16.
downlink: Specifies a downlink interface.
uplink: Specifies an uplink interface.
Usage guidelines
If you have configured an interface as the downlink interface of a monitor link group, do not configure its subinterfaces as the uplink interfaces of any monitor link group. Otherwise, the Monitor Link operation might be interrupted.
To avoid interrupting Monitor Link operation, do not assign the aggregate interface and member ports of an aggregate group to the same monitor link group.
The state of subinterfaces adapts to the state of the interface. Do not assign the interface and its subinterfaces to the same monitor link group. Otherwise, the monitor link group performance might be affected.
You can assign an interface to only one monitor link group.
You can also assign an interface to a monitor link group with the port command in monitor link group view.
Examples
# Configure FortyGigE 1/1/1 as an uplink interface and FortyGigE 1/1/2 as a downlink interface for monitor link group 1.
<Sysname> system-view
[Sysname] monitor-link group 1
[Sysname-mtlk-group1] quit
[Sysname] interface fortygige 1/1/1
[Sysname-FortyGigE1/1/1] port monitor-link group 1 uplink
[Sysname-FortyGigE1/1/1] quit
[Sysname] interface fortygige 1/1/2
[Sysname-FortyGigE1/1/2] port monitor-link group 1 downlink
