Before Configuring Trunks; Multilink Trunking Configuration Rules - Nortel BayStack 410 24T Using Manual

Before Configuring Trunks

When you create and enable a trunk, the trunk members (switch ports) take on
certain settings necessary for correct operation of the MultiLink Trunking feature.
These settings, along with specific configuration rules, must be considered before
configuring your MultiLink Trunk.

MultiLink Trunking Configuration Rules

The MultiLink Trunking feature is deterministic; that is, it operates according to
specific configuration rules. When creating trunks, consider the following rules
that determine how the MultiLink Trunk reacts in any network topology:
•
309985-B Rev 00
Read the configuration rules provided in the next section,
Trunking Configuration
Determine which switch ports (up to four) are to become trunk members
(the specific ports making up the trunk):
A minimum of two ports are required for each trunk.
a.
Ensure that the chosen switch ports are set to Enabled, using the Port
b.
Configuration screen (see "Port Configuration" on page 3-52) or
through network management.
Trunk member ports must have the same VLAN configuration.
c.
All network cabling should be complete and stable before configuring any
trunks, to avoid configuration errors.
Consider how the existing spanning tree will react to the new trunk
configuration (see "Spanning Tree Considerations for MultiLink
on page 1-76).
Consider how existing VLANs will be affected by the addition of a trunk.
After completing the above steps, see "MultiLink Trunk Configuration"
on page 3-57 for screen examples and field descriptions that will help you
configure your MultiLink Trunks.
Any port that participates in MultiLink Trunking must be an active port (set to
Enabled via the Port Configuration screen or through network management).
