How does an SACG select a principal server in case of multiple TSM servers?


If an SACG connects to multiple TSM servers, the SACG selects the server that becomes active first as the principal server.

In the case of multi-load balancing of S-series switches, how does tunnel management select tunnels in multiple tunnels?
If the selected tunnel state changes, such as the first down, a tunnel is randomly selected from the alternate tunnel.

Setting the boot disk for multiple RAID arrays
To set the OS boot disk for a server configured with multiple RAID arrays, perform the following steps: -LSI 2308 and 3008 RAID cards: Log in to the RAID card configuration interface, choose the system drive in the SAS topology, and press ALT+B to set the boot disk. -LSI 2208 and 3108 RAID cards: Enter the VD property page, and choose Set Boot Drive and click Go. -SoftRAID: On the SoftRAID management interface, choose Configure > Select Boot Drive and press Enter.

DHCP client cannot obtain a correct IP address
The request packets (DHCP discover) are broadcast by the DHCP clients. If multiple DHCP servers are located on the same subnet (for example, bogus DHCP server), the clients may obtain IP addresses from a bogus DHCP server. To address this problem, configure DHCP snooping. Then clients can receive DHCP packets from only the trusted DHCP server. Perform the following configuration: [Huawei] dhcp enable [Huawei] dhcp snooping enable [Huawei] interface gigabitethernet 1/0/1 //Enter the view of the interface connected to the DHCP client. [Huawei-GigabitEthernet1/0/1] dhcp snooping enable [Huawei-GigabitEthernet1/0/1] quit [Huawei] interface gigabitethernet 1/0/2 [Huawei-GigabitEthernet1/0/2] dhcp snooping trusted //Configure the interface of the DHCP server as the trusted interface. [Huawei-GigabitEthernet1/0/2] quit Note: - When you configure DHCP snooping on a Layer 2 access device, steps 1, 2, and 3 are mandatory and must be performed in the following sequence. - When you configure DHCP snooping on a DHCP relay agent, only steps 1 and 2 are required.

How to select a tunnel among multiple tunnels working in load balancing mode
If the number of tunnels is set to 6 for load balancing, how to select six LSP tunnels from eight ones during tunnel iteration? If the selected tunnels enter the Down state, how to re-select tunnels? If the selected tunnels go Up from the Down state, how to re-select tunnels? The TNLM randomly selects six tunnels and then returns them to the RM. If the status of the selected tunnels changes (for example, the first tunnel enters the Down state), the TNLM randomly selects another tunnel from two candidate ones. If the tunnels go Up from the Down state and there are fewer than six tunnels for load balancing, the TNLM is triggered to re-select six tunnels and then returns them to the RM. Otherwise, the status of tunnels does not affect load balancing.
