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.
