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 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.
