Description
tmsh run cm sniff-updates

Displays the time threshold for the time difference between devices in the trust domain. If the time difference between devices exceeds the configured threshold value, the BIG-IP system logs an error.
tmsh show cm device
Displays the time difference, in seconds, between the local device and each of the other devices in the trust domain.
tmsh show cm traffic-group

  • The local device stops receiving SOD status messages.
  • An interface on the local device begins receiving SOD status messages again.
tmctl sod_tg_conn_stat
Displays SOD messaging statistics for each type of message sent and received.
tmctl sod_tg_msg_stat
Displays the outgoing packets from the SOD daemon to the other devices in the device group.

  • A device with the specified device name already exists in the trust domain.
  • The BIG-IP software version (including hotfix version) on the specified device does not match the version on the local device.
  • The time on the specified device is out of sync with the current device by some number of seconds.
  • A config sync address is not configured on the specified device.
