To configure the database synchronize feature between the master subnet ma nag er a nd on e or m ore
standby (slave) subnet managers , en te r t he
ib sm db-sync
command in Global Configuration mode. To
disable database synchronization features, use the
no

Syntax Description subnet prefix Specifies the subnet prefix of the IB subnet on which you want to configure
performance monitoring.
prefix Subnet prefix of the IB subnet on which you want to configure performance
monitoring
enable Enables database synchronization on your IB fabric.
max-backup-sms Specifies the maximum number of backup subnet managers t hat wi ll
synchronize with the master SM.
Note Although we offer this configuration option, the master SM
currently only supports one standby.
max Maximum number of backup subnet managers that will synchronize with
the master SM. This value defaults to 1.
session-timeout Specifies the interval, in seconds, during which a synchronization session
status MAD packet must arrive at the master SM to maintain
synchronization. This value should be greater than the poll-interval value.
timeout Timeout interval, in seconds. This value defaults to 10 seconds.
poll-interval Interval at which the master SM polls an active slave SM to verify
synchronization.
interval Poll interval, in seconds. This value defaults to 3 seconds.
cold-sync-timeout Allots a maximum amount of time in which to perform a cold sync. During
the cold sync, the master SM copies all out-of-sync tables to the standby.
cs-timeout Cold sync interval, in seconds. This value defaults to 10 seconds.
cold-sync-limit Specifies the maximum number of cold syncs that may take place during the
cold sync period. This value defaults to 2.
cs-limit Maximum number of cold syncs per cold sync period (integer).
cold-sync-period Specifies the length of the interval during which cold syncs may occur.
cs-period Duration, in seconds, of the cold sync period. This value defaults to 900
seconds.
