3-10

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.

3.6 DISABLING TRUNKING

To turn off trunking, at the LCM prompt:

1. Type trunk <PORT-RANGE> off

For example, trunk 2-4 off

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.
