Creating Port Channels
Port channels, also known as link aggregation groups (LAGs), allow you to combine multiple full-duplex
Ethernet links into a single logical link. Network devices treat the aggregation as if it were a single link, which
increases fault tolerance and provides load sharing. You assign the port-channel (LAG) VLAN membership
after you create a port-channel. The port channel by default becomes a member of the management VLAN.
A port-channel (LAG) interface can be either static or dynamic, but not both. All members of a port channel
must participate in the same protocols. A static port-channel interface does not require a partner system to
be able to aggregate its member ports.
Note:
If you configure the maximum number of dynamic port-channels (LAGs) that your platform
supports, additional port-channels that you configure are automatically static.
Static LAGs are supported. When a port is added to a LAG as a static member, it neither transmits nor receives
Link Aggregation Control Protocol (LACP) Protocol Data Units (PDU)s.
Port Channel Summary
Use the
Port Channel Summary
page to group one or more full duplex Ethernet links to be aggregated
together to form a port-channel, which is also known as a link aggregation group (LAG). The switch can treat
the port-channel as if it were a single link.

Port Channel Summary
Port Channel Summary Fields
Field
Description
Name
A unique name to identify the port channel. Depending on the type of port channel, this name is automatically
assigned by the system or can be configured by a system administrator.
Type
The type of port channel:
•
Dynamic
Uses LACP PDUs to exchange information with the link partners to help maintain the link state. To
use Dynamic link aggregation on this port channel, the link partner must also support LACP.
•
Static
Does not require a partner system to be able to aggregate its member ports. When a port is added to
a port channel as a static member, it neither transmits nor receives LACP PDUs.
When configuring a port channel (by clicking
Edit
), use the
Static Mode
field to set the port channel type. If the
Static Mode
is disabled, the port channel type is
Dynamic
.
Admin Mode
The administrative mode of the port channel. When disabled, the port channel does not send and receive traffic.
STP Mode
The spanning tree protocol (STP) mode of the port channel. When enabled, the port channel participates in the
STP operation to help prevent network loops.
Link State
The current link status of the port channel, which can be
Up
,
Up (SFP)
, or
Down
.
Link Trap
The link trap mode of the port channel. When enabled, a trap is sent to any configured SNMP receiver(s) when
the link state of the port channel changes.
