8-port Gigabit Ethernet Switch User’s Guide

Load balancing is automatically applied to the links in the port trunk group, and a link failure within the group causes the
network traffic to be directed to the remaining links in the group.
Note:
The Spanning Tree Protocol will treat a port trunk group as a single link, on the switch level. On
the port level, the STP will use the port parameters of the base port in the calculation of port
cost and in determining the state of the link aggregation group. If two redundant port trunk
groups are configured on the Switch, STP will block one entire group – in the same way STP
will block a single port that has a redundant link.
To configure a port trunk group, highlight
Port Trunking
on the
Main Menu
and press
Enter
.

Enter the group ID of one of the six possible port trunk groups configurable on the switch in the
Group ID:[

field. Enter
the desired port number in the second field and specify the
Group Width:[
2
]
.
This is the number of ports, in sequential
order from the base port that will be included in the port trunk group.
The
Method:<

>
field can be toggled between
TRUNK
and
Disabled
– and is used to turn a port trunk group on
or off. This is useful for diagnostics, to quickly isolate a bandwidth intensive network device or to have an absolute backup
port trunk group that is not under automatic control.
Highlight
Apply
and press
Enter
to make the port trunk group configuration active. The
Anchor
column displays what
port is receiving BPDUs, SNMP packets, etc. This is usually the same as the
Master
port. However, if the link is down
for
the master port, the closest port with a valid link will become the new anchor port.
Use
Save Changes
from the
Main Menu
to enter the configuration into NV-RAM.
