no trunk [ethernet] PORT-LIST
Description: Add or remove a switch port from a port trunk.
Each port on the switch (up to 8 ports total) can be made
a member of a port trunk. The 'no trunk' command can be used
to remove ports from an existing trunk. The switch supports
any one of the following trunk groups:
Trunk - A static port grouping in which no protocols are used
to create or maintain the trunk (type 'trunk').
LACP - A port groping in which trunk membership is dynamically
determined using the IEEE 802.1ad Link Aggregation Protocol.
For LACP trunks the trunk group may instead be manually
congured as static trunk.
Manually conguring a static LACP trunk allows you to specify
which ports are members and still congure advanced LACP
features (type 'lacp').
Any trunk group can have up to 8 member ports. All ports that
belong to the same trunk group must have the same port type.
All trunk groups use an algorithm that considers the source and
destination MAC addresses for load distribution.
General Considerations: To avoid broadcast storms, or
loops in your network while conguring trunks, rst
disable or disconnect all the ports you wish to add or
remove from both sides of the trunk. Once done conguring
the trunk, enable or re-connect the ports.
