Q；Two USG2210s do the two-node cluster hot backup ,and failover is abnormality ,when we swap the external network interface of host firewall ,the failover isn’t working and the operation is breaking
A:When remote accessing equipment to have a check , we can find the edition of equipment is V100R002C01SPC006 at present and the configuration is regular , but the preemption function of is not turned on .The edition must configure the preemption mode if it wants to achieve two-node cluster hot backup failover , or the failover is exception after we affirm that the edition of V100R002C01SPC006 is too old with development engineers . Because the BUG of VGMP ,the host administer group inspect backup administer group without preemption mode . The backup administer group don’t inspect host administer group .If we want to achieve the configuration of two-node cluster hot backup without preemption mode , it will only be solved by updating the edition software of equipment . It needs to have two operation of updating to edition V100R005C00SPC700 ,because the edition is not enough high to update the objective edition .It needs updating totransition edition at frist and then to objective edition
The V100R002C01SPC006 edition exits the BUG of VGMP
When we fall across the similarity fault ,we can cansider that if it is aroused by the BUG of equipment edition after ensuring that there is no problems at the configuration of equipment .We suggest to check the history equipment alarm information or call the development engineers to make sure it .
