Can dual network adapters on S series switch obtain primary and secondary DHCP servers respectively

3

When S series switches (except S1700 switches) are configured as DHCP servers in a two-node cluster, a terminal cannot use its dual network adapters to obtain IP addresses from the active and standby DHCP servers respectively.

Can the terminal with dual network adapters obtain IP addresses from the active and standby DHCP servers
When S series switches excluding the S1700 function as DHCP servers, the terminal with dual network adapters cannot obtain IP addresses from the active and standby DHCP servers.

Connect the S series switches to servers by using link aggregation
To connect a standalone or a stacked S series switch (except the S1700) to a server with dual or multiple network adapters, first configure link aggregation on interfaces of the switch. For example, to connect the S5700 to a server with dual network adapters, create an Eth-Trunk between two interfaces on the S5700 and then connect the S5700 to the server using two network cables. You can connect a switch to a server with dual network adapters in the following modes: 1. round robin (link aggregation must be configured on the switch). Characteristics: (1) All the links work in load balancing state and packets are transmitted on a per-packet basis to each link in round robin mode. If you ping the address 10.1.1.1 from the server, packets are transmitted on two network adapters of the server. (2) This mode improves bandwidth and supports error tolerance. If one link fails, traffic is switched to the other normal link. 2. active-backup (This mode can be applied without configuration on the switch). Characteristics: One port works in active state and another port works in backup state. All traffic is transmitted on the active link and there is no traffic on the backup link. If the active port goes Down, the backup port changes to the active state. 3. 802.3ad (link aggregation in LACP mode needs to be configured on the switch). 4. adaptive load balancing (no configuration is required on the switch). In this mode, you do not need to configure the switch because the two network adapters that are bound using bonding technology use different MAC addresses.

Configure the primary and secondary IP addresses for a CE series switch
Configure the primary and secondary IP addresses for a CE series switch as follows: 1. Run the ip address ip-address { mask | mask-length } command in the interface view to configure the primary IP address for an interface. 2. Run the ip address ip-address { mask | mask-length } sub command in the interface view to configure the secondary IP address for an interface.
