Ports can be statically grouped into an aggregate link to increase the bandwidth
of a network connection or to ensure fault recovery. Or you can use the Link
Aggregation Control Protocol (LACP) to automatically negotiate a trunk link
between this switch and another network device. For static trunks, the switches
have to be compatible with the Cisco EtherChannel standard. For dynamic trunks,
the switches have to comply with LACP. This switch supports up to six trunks.
For example, a trunk consisting of two 1000 Mbps ports can support an aggregate
bandwidth of 4 Gbps when operating at full duplex.
Use this command to add a port to a trunk. Use the no form to remove
a port from a trunk.
Command Syntax
channel-group channel-id no channel-group
channel-id - Trunk index (Range: 1-6)
Default Setting
A new trunk contains no ports.
Command Mode
Interface Configuration (Ethernet)
Command Usage
When configuring static trunks, the switches must be compatible with the
Cisco EtherChannel standard.
Use no channel-group to remove a port group from a trunk.
Use no interfaces port-channel to remove a trunk from the switch.
The maximum number of ports that can be combined as a static trunk -
PowerConnect 3248: 4 10/100 Mbps ports, 2 1000 Mbps ports; PowerConnect 5224:
6 1000 Mbps ports.
All links in a trunk group must operate at the same data rate and duplex
mode.
Example
The following example creates trunk 1 and then adds port 11:
