Configuring Dynamic Link Aggregation

Application Examples

Dynamic link aggregation groups are treated by the switch's software the same way it treats individual
physical ports.This section demonstrates this feature by providing sample network configurations that use
dynamic aggregation along with other software features. In addition, tutorials are provided that show how
to configure these sample networks by using Command Line Interface (CLI) commands.

Sample Network Overview

The figure below shows two VLANs on Switch A that use two different link aggregation groups. VLAN
10 has been configured on dynamic aggregate group 5 with Spanning Tree Protocol (STP) with the high-
est (15) priority possible. And VLAN 12 has been configured on dynamic aggregate group 7 with 802.1Q
tagging and 802.1p priority bit settings.
The steps to configure VLAN 10 (Spanning Tree example) are described in
ning Tree Example" on page
described in "Link Aggregation and QoS Example" on page
Note. Although you would need to configure both the local (i.e., Switch A) and remote (i.e., Switches B
and C) switches, only the steps to configure the local switch are provided since the steps to configure the
remote switches are not significantly different.
