Zyxel XGS3700-48 [9/9] Configuration file backup restore

ZyXEL Communication Crop, 8

“force master enable” setting. It will take 70 seconds for master change and 70

seconds of ping lost are expected.

If turn on/off any line card (SW3-SW8) or add/remove any line card (besides the

master & backup master). 0 to 1 ping lost are expected for LACP convergence.

Caution:

When master switch is turned off then back online, as “Switch 1” has “force master

enable” the entire stacking group will trigger the re-initialization process. It will take

around 70 seconds to finish the re-initialization. During this process, the whole

stacking units will not be forwarding any data.

To avoid the situation, enable force master on “Switch 2” before putting back the

“Switch 1”. Master will still keep on “Switch 2” due to its longer system up time.

3.2.2 Configuration File Backup / Restore

The configuration file maintained by master switch on stacking mode. All others

switches on stacking group will sync with master switch when:

 Click “Save” button on web GUI or type “write memory” on CLI.

 New master join stacking group. All configuration file will sync with new master.

 New line card install. Line card will sync configuration file with master.

 Configuration file restore.

Caution:

if in an event that master goes down and need to be replaced with a new switch,

please ensure the new switch has ONLY default stacking configuration and the “force

master mode” must be disabled. To avoid the trigger of master re-election process

which can cause the whole stacking configuration loss.

In stacking mode, during the backup take over it will apply startup config again. ONLY

save configuration will apply startup configuration to all the switches. Please ensure

to save configuration after any configuration change. Or configuration will not sync to

backup and the modified configuration will be lost after master power off.
