Conﬁguring Your ELS100-16TX

For ELS100-16TX B, at the LCM prompt:

b.Type trunk 3-10,14-15 on

For ELS100-16TX C, at the LCM prompt:

c.Type trunk 3-10 on

Each ELS100-16TX determines which ports are part of which Trunk Group. After Trunk Group conﬁguration, the ELS100- 16TXs complete the standard 802.1d Spanning Tree state changes, treating each Trunk Group as a single 802.1d Spanning Tree port.

802.1d Spanning Tree takes about thirty seconds to resolve which ELS100-16TX ports are to become forwarding ports. As ports within a Trunk Group become forwarding ports, trafﬁc within the Trunk Group is momentarily halted to guarantee the ﬁrst-in, ﬁrst-out ordering of the Ethernet packets.

Note: The ELS100-16TX-to-ELS100-16TX connections must be point- to-point. There cannot be any other devices on those Ethernets. The ports used for trunking can be in any order. However, both ends of the ELS100-16TX-to-ELS100-16TX connections must have trunking turned on for the ports that are being used for the connections.

3.6 DISABLING TRUNKING

To turn off trunking, at the LCM prompt:

1.Type trunk <PORT-RANGE> off

For example, trunk 2-4 off
