SMC Networks SMC7724M/VSW manual Port Trunk Configuration, Command Usage

CONFIGURING THE SWITCH

Port Trunk Configuration

Ports can be combined into an aggregate link to increase the bandwidth of a network connection where bottlenecks exist, or to ensure fault recovery. You can configure trunks between any two switches of the same type. You can create up to six trunks at a time. The uplink ports can be trunked together and the VDSL ports can be trunked together, the details are given in the table below.

Switch	Ports	Port Type	Number	Ports per	Maximum
			of Trunks	Trunk	Aggregate
					Bandwidth
SMC7724M/	1 - 24	VDSL	1 - 6	2 - 24	720 Mbps
VSW
	25, 26	1000BASE-T	1	2	4 Gbps

The switch supports both static trunking and dynamic LACP (Link Aggregation Control Protocol.) LACP configured ports will automatically negotiate a trunked link with LACP-configured ports on another device. You can configure any number of the ports on the switch as LACP, as long as they are not already configured as part of another trunk. If ports on another device are also configured as LACP, the switch and the other device will negotiate a trunk link between them. If an LACP trunk consists of more than four ports, all other ports will be placed in a standby mode. Should one link in the trunk fail, one of the standby ports will automatically be activated to replace it.

Command Usage

•Finish configuring a port trunk before you connect the corresponding network cables between switches.

•You can configure one trunk group, containing up to four ports as a dynamic LACP trunk.
