F5 HA - TMOS 201 Flashcards
What is ConfigSync?
Configuration Synchronization; there are options to synch the configurations between HA members.
1) Manual Incremental Synch
2) Maual Full Synch
3) Automatic with Incremental Synch
How do you save the configuration via tmsh?
tmsh save sys config
What configurations are not synch’d between HA members?
1) Excluding floating self-ips, network configurations such as local-traffic only like non-floating ips, and vlans.
2) UCS archives, logging, certificates
3) Provisioned modules (under resource provisioning)
What are traffic groups?
A traffic group is a collection of related configuration objects, such as a floating self IP address, a virtual IP address, and a SNAT translation address, that run on a BIG-IP device. Together, these objects process a particular type of application traffic on that device.
What is vlan failsafe?
The BIG-IP system monitors network traffic on the VLAN. If the BIG-IP system detects a loss of network traffic on the VLAN, the VLAN failsafe timer begins and the BIG-IP system attempts to generate traffic to nodes or the default router that is accessible through the VLAN.
Where is mac masquerading configuration located?

What are the 5 steps to setting up HA?
1) DSC Configuration
- unique device names
- configure vlans
- configure self-ip
- synch ntp
2) Configure DSC communications
Device Mgmgt > Devices
- add internal self-ip for configsync/mirror connection/and failover heartbeat
3) Establish Device Trust
Device Mgmt > Device Trust
- Add peer mgmt ip address/admin username and password
4) Establish sync-failover device group
Device Mgmt > Device Group
- add which devices in the sync-failover cluster
- choose sync type
5) Synch config data
- push config from primary to secondary device
