7The DHCP server can then assign a specific IP address based on the DHCP request.

5.8.3Troubleshooting

Check the client A’s IP address. If it did not receive the IP address 172.16.1.18, make sure:

1Client A is connected to the Switch’s port 2 in VLAN 102.

5.9How to Use Link Aggregation to Group Multiple Ports into One Logical Link

Link aggregation (trunking) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports if for example, it is cheaper to use multiple lower-speed links than to under-utilize a high-speed, but more costly, single-port link.

However, the more ports you aggregate then the fewer available ports you have. A trunk group is one logical link containing multiple ports.

The beginning port of each trunk group must be physically connected to form a trunk group.

The Switch supports both static and dynamic link aggregation. The Switch supports the IEEE 802.3ad standard for static and dynamic (LACP) port trunking. This standard describes the Link Aggregation Control Protocol (LACP), which is a protocol that dynamically creates and manages trunk groups.

Note: In a properly planned network, it is recommended to implement static link aggregation only. This ensures increased network stability and control over the trunk groups on your Switch.

5.9.1 Static Port Trunking

This example shows you how to create a static port trunk group for ports 2-5.

1Make your physical connections - make sure that the ports that you want to belong to the trunk group are connected to the same destination. The following figure shows ports 2-5 on switch A connected to switch B.
