additional hardware on your network. You can use LCM to
configure trunking. You can enable trunking between ATXs or
between an ATX and a Fast Network 10. For more information on
trunking, see section, 1.9 Trunking.
3.5.1 Enabling Trunking
To enable trunking you would:
1. Connect the desired ports of the ATXs together using the
appropriate cables.
ATX A is handling only a small traffic load. Therefore, the A to
B trunk group has just two ports per ATX. ATXs B and C are
expected to support a higher traffic load. Therefore, the B to C
group has eight ports.
2. Using LCM, turn on trunking for the connected ports on each
ATX.
For ATX A, at the LCM prompt:
Type: trunk 2,3 on
For ATX B, at the LCM prompt:
Type:
trunk 3-10, 14-15 on
For ATX C, at the LCM prompt:
Type: trunk 3-10 on
Each ATX automatically determines which ports are part of
which trunk group. After trunk group configuration, the ATXs
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 could take up to thirty seconds to resolve
which ATX ports are to become forwarding ports. As ports within
a trunk group become forwarding ports, traffic within the trunk
