Configuring Your ELS10-26
For ELS10-26 B, at the LCM prompt:
b. Type
trunk 3-10,14-15 on
For ELS10-26 C, at the LCM prompt:
c. Type
trunk 3-10 on
Each ELS10-26 determines which ports are part of which Trunk
Group. After Trunk Group configuration, the ELS10-26s
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 ELS10-26 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 ELS10-26-to-ELS10-26 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
ELS10-26-to-ELS10-26 connections must have trunking turned on
for the ports that are being used for the connections.
