Can the interface on the AR be configured with IPSec when it dynamically obtains an IP address
The interface can be configured with IPSec when it dynamically obtains an IP address. When the local interface is configured with a dynamic IP address and the remote interface is configured with a fixed IP address, you can configure an IPSec policy template on the remote end to implement IPSec. The 3G interface is used as an example. IKE negotiation is used. The key configuration is as follows: Interface with a dynamic IP address # ike peer peer_3g_1 v1 pre-shared-key cipher %^%#JvZxR2g8c;a9~FPN~n'$7`DEV&=G(=Et02P/%\*!%^%# //Set the preshared key to huawei. remote-address 10.5.39.160 //Specify the fixed IP address for the remote end. # ipsec proposal ipsec //Use default security parameters. # ipsec policy ipsec 1 isakmp //Configure an IPSec policy. security acl 3000 ike-peer peer_3g_1 proposal ipsec # interface Cellular0/0/0 ipsec policy ipsec //Apply the IPSec policy to the 3G interface. Other configurations of the 3G interface are not mentioned. # acl 3000 //Configure an ACL. IPSec protects the packets matching the ACL. ... # Interface with a fixed IP address # ipsec proposal ipsec # ike peer peer_3g_2 v1 //The remote interface is configured with a dynamic IP address, so there is no need to specify an IP address for the remote interface. pre-shared-key cipher %^%#K{JG:rWVHPMnf;5\|,GW(Luq'qi8BT4nOj%5W5=)%^%# //Set the pre-shared key to huawei. # ipsec policy-template temp 1 //Configure an IPSec policy template. ike-peer peer_3g_2 proposal ipsec # ipsec policy ipsec 1 isakmp template temp //Bind the IPSec policy to the IPSec policy template. # interface GigabitEthernet 1/0/0 //The interface uses a fixed IP address. ipsec policy ipsec ip address 10.5.39.160 255.255.255.255 #

How is business continuity ensured when HyperMetro arbitration fails?
When the arbitration is faulty, the storage system will switch the arbitration mode to the static priority mode within 30 seconds. If the switchover is successful, services will be switched to the preferred site. If the arbitration has not been switched to the static priority mode yet and the links between arrays fail (a rare occurrence), services will be interrupted.
