• Trunk Mode field --- indicates the Trunk Mode for each of the trunks:
– Trunk I1 --- The Trunk Mode field for trunk I1 is set to Enhanced.
When in this mode, the switch evenly distributes source MAC
addresses to the trunk members, balancing traffic throughout each
trunk (see Note on page 1-31
).
• Trunk Status field --- indicates the Trunk Status for each of the trunks. When
set to Enabled, the configuration settings for that specific trunk are activated.
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.
Before configuring any MultiLink trunk, follow these steps:
1.
Read the configuration rules provided in the next section, “MultiLink
Trunking Configuration Rules.”
2.
Determine which switch ports (up to 4) are to become trunk members (the
specific ports making up the trunk):
a.
A minimum of two ports are required for each trunk.
b.
Ensure that the chosen switch ports are set to Enabled, using the Port
Configuration screen (see “Port Configuration” on page 3-23) or
through network management.
c.
Trunk member ports must be in the same VLAN.
3.
All network cabling should be complete and stable before configuring
any trunks, to avoid misconfiguration errors.
4.
Consider how the existing spanning tree will react to the new trunk
configuration (see “Spanning Tree Considerations
” on page 1-40).
5.
Consider how existing VLANs will be affected by the addition of a trunk;
when MultiLink Trunking is active, only five VLANs are allowed.
6.
After completing the above steps, see “MultiLink Trunk Configuration”
on page 3-26 for screen examples and field descriptions that will help you
configure your MultiLink trunks.
