display switchover state

Syntax

display switchover state [ member-id ]

View

Any view

1-8

Default Level

1: Monitor level

Parameters

member-id: Specifies the ID of a member of an IRF virtual device. The value range depends on the

current number of members and their member IDs. With this argument provided, the command

displays the master/slave switchover state of the specified member. Without this argument, the

command displays the master/slave switchover state of the master.

Description

Use the display switchover state command to display the master/slave switchover states of

members of an IRF virtual device.

An IRF functions like a logical distributed device with multiple standby main boards (SMBs). The

master functions like the active main board (AMB), and the slaves function like the SMBs. An IRF

virtual device uses member IDs to uniquely identify member devices, whereas a distributed device

uses slot IDs to uniquely identify cards. Therefore, in the output information of this command, a

member device is also identified by the slot ID, which is equal to the member ID.

Examples

# Display the master/slave switchover states of the master.

<Sysname> display switchover state

Master HA State to Slot 1: Slave is absent.

Master HA State to Slot 2: Slave is absent.

Master HA State to Slot 4: Waiting batch backup request from slave.

Master HA State to Slot 5: Slave is absent.

Master HA State to Slot 6: Realtime backup to slave.

Master HA State to Slot 7: Realtime backup to slave.

Master HA State to Slot 8: Slave is absent.

Master HA State to Slot 9: Slave is absent.

Master HA State to Slot 10: Slave is absent.

The above information shows that:

z Slaves 1, 2, 5, 8, 9 and 10 are absent, which means that these devices are not in use.

z The master is waiting for the batch backup request from slave 4.

z Slaves 6 and 7 are performing real time backup.

Table 1-6 display switchover state command output description for the master

Field Description

Master HA State to Slot slot-number

Indicates that this output information is generated by the

master.

# Display the master/slave switchover state of slave 6.

<Sysname> display switchover state 6

Slave HA State: Receiving realtime data.

The above information shows that slave 6 is receiving real time backup data.

Table 1-7 display switchover state command output description for a slave

Field Description

Default Level

3: Manage level

Parameters

None

Description

Use the irf auto-update enable command to enable the auto update of boot files for an IRF virtual

device.

Use the undo irf auto-update enable command to disable this function.

This function is enabled by default.

Note the following:

z Ensure that the device and the master have the same software version before adding a device

into the IRF virtual device.

z After automatically loading the master’s boot file, a slave configures the file as the boot file to be

used at the next boot and automatically reboots.

z Because system boot file occupies large memory space, to make the auto upgrade succeed,

ensure that there is enough space on the storage medium of the slave.

z If the downloaded boot file and the local boot file have duplicate file names, the local file is

overwritten. Therefore, ensure that there is not any local file that has the same name as the boot

file to be downloaded.

Default Level

3: Manage level

Parameters

timer: Bridge MAC address preservation mode for an IRF virtual device. With this keyword specified,

the bridge MAC address is preserved for 6 minutes when the master leaves.

always: Bridge MAC address preservation mode. With this keyword specified, the bridge MAC

address is preserved permanently.

Description

Use the irf mac-address persistent command to configure the preservation time of the bridge MAC

address of an IRF virtual device.

Use the undo irf mac-address persistent command to configure the IRF virtual device not to

preserve the bridge MAC address when the master leaves.

By default, the bridge MAC address of an IRF virtual device is preserved for 6 minutes.

z Preserve for six minutes: When the master leaves, the bridge MAC address does not change

within six minutes. If the master does not come back when the preservation time expires, the IRF

virtual device uses the bridge MAC address of the newly elected master as its bridge MAC

address.

1-12

z Preserve permanently: No matter whether the master leaves the IRF virtual device or not, the

bridge MAC address of the IRF virtual device remains unchanged.

z Not preserved: As soon as the master leaves, the IRF virtual device uses the bridge MAC

address of the newly elected master as its bridge MAC address.

Examples

# Configure the bridge MAC address of the IRF virtual device to be preserved permanently.

Parameters

member-id: Specifies the ID of a member of an IRF virtual device. The value range depends on the

current number of members and their member IDs. With this argument provided, you can specify a

priority for another member on this device. To view the member IDs, use the display irf command.

priority: Priority value, in the range 1 to 32.

Description

Use the irf member priority command to specify a priority for a member device.

Use the undo irf member priority command to restore the default.

By default, the priority of a member device is 1.

The greater the priority value, the higher the priority. A member with a higher priority is more likely to

be the master.

Note the following:

z You can specify a priority for a member of the current IRF virtual device only.

z The priority setting takes effect right after your configuration.

Examples

# Specify a priority for the local device.

<Sysname> display irf

Switch Role Priority CPU-Mac

+1 Slave 29 00e0-fc00-1115

2 Slave 1 00e0-fc00-1615

1-13

*3 Master 32 00e0-fc00-1015

9 Slave 30 00e0-fc00-1515

--------------------------------------------------------

* indicates the device is the master.

+ indicates the device through which the user logs in.

The Bridge MAC of the IRF is: 00e0-fc00-1000

Auto upgrade : yes

Mac persistent : always

The above information shows that the member ID of the local device is 3, and you can specify a

priority for the local device by providing its member ID.

<Sysname> system-view

[Sysname] irf member 3 priority 16

# Specify a priority for member 2 of the current IRF virtual device.

<Sysname> system-view

3: Manage level

Parameters

member-id: Specifies the ID of a member of an IRF virtual device. The value range depends on the

current number of members and their member IDs. With this argument provided, you can change a

member ID of another member on this device. To view the member IDs, use the display irf

command.

new-member-id: New ID of the IRF member, which ranges from 1 to 10.

Description

Use the irf member renumber command to set a member ID for a device.

Use the undo irf member renumber command to remove the configuration.

By default, the member ID of a member device is 1.

Note the following:

z The above setting takes effect at the reboot of the device.

z For an IRF virtual device, member IDs are not only used to identify devices, but also used to

configure IRF ports and member priorities. Therefore, member ID change may cause device

configuration changes or even losses, so change member ID with caution. For example, three
