INK GGREGATION
Ports can be statically grouped into an aggregate link (i.e., trunk) 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 comply with the
Cisco EtherChannel standard. For dynamic trunks, the switches have to
comply with LACP. This switch supports up to 16 trunks. For example, a
trunk consisting of two 1000 Mbps ports can support an aggregate
bandwidth of 4 Gbps when operating at full duplex.

Command Function
Manual Configuration Commands
interface port-channel Configures a trunk and enters interface
configuration mode for the trunk
port channel Sets the load-distribution method among ports
load-balance in aggregated links
channel-group Adds a port to a trunk
Dynamic Configuration Commands
lacp Configures LACP for the current interface
lacp admin-key Configures a port's administration key
lacp port-priority Configures a port's LACP port priority
lacp system-priority Configures a port's LACP system priority
lacp admin-key Configures an port channel's administration key
lacp timeout Configures the timeout to wait for next LACPDU IC (Port Channel)
Trunk Status Display Commands
show interfaces status Shows trunk information
port-channel
show lacp Shows LACP information
show port-channel Shows the load-distribution method used on
load-balance aggregated links

UIDELINES FOR REATING
General Guidelines –
Finish configuring trunks before you connect the corresponding network
◆
cables between switches to avoid creating a loop.
A trunk can have up to 8 ports.
◆
The ports at both ends of a connection must be configured as trunk
◆
ports.
