Table 12 - EtherChannel Fields
Field Description
Channel Group Number A number from 1 to 6 that identifies this EtherChannel. You can configure as many as six EtherChannels.
Channel Mode Determines how ports become active. With all options except On, negotiations occur to determine which ports become active. Incompatible
ports are put into an independent state and continue to carry data traffic, but do not participate in the EtherChannel.
IMPORTANT: Ensure that all of the ports in an EtherChannel are configured with the same speed and duplex mode.
These are the available modes:
• Static—All ports join the EtherChannel, without negotiations. This mode can be useful if the remote device does not support the
protocols required by the other modes (see below). The switches at both ends of the link must be configured in On mode.
• PAgP—This mode enables Port Aggregation Protocol (PAgP), a Cisco-proprietary protocol. The port responds to requests to create
EtherChannels but does not initiate such negotiations. This "silent" mode is recommended when a port is connected to a device, such as
a file server or a packet analzyer, that is unlikely to send PAgP packets. A port in the Auto mode can form an EtherChannel with another
port in the Desirable mode.
• PAgP (non-silent)—This mode is the same as Auto mode but is recommended when the port is connected to a device that is expected to
be active in initiating EtherChannels. A port in the Auto mode can form an EtherChannel with another port in the Desirable mode.
• PAgP Desirable—This mode enables Port Aggregation Protocol (PAgP), a Cisco-proprietary protocol. The port initiates negotiations to
form EtherChannels by sending PAgP packets to other ports. This "silent" mode is recommended when a port is connected to a device,
such as a file server or a packet analzyer, that is unlikely to send PAgP packets. A port in the Desirable mode can form an EtherChannel
with another port that is in the Desirable or Auto mode.
• PAgP Desirable (non-silent)—This mode is the same as Desirable mode but is recommended when the port is connected to a device that
is expected to be active in initiating EtherChannels.
• LACP (Active)—This mode enables Link Aggregation Control Protocol (LACP) unconditionally. The port sends LACP packets to other ports
to initiate negotiations to create EtherChannels. A port in Active mode can form an EtherChannel with another port that is in Active or
Passive mode. The ports must be configured for full duplex.
• LACP (Passive)—This mode enables Link Aggregation Control Protocol only if an LACP device is detected at the other end of the link. The
port responds to requests to create EtherChannels but does not initiate such negotiations. The ports must be configured for full duplex.
Ports The ports that can participate in this EtherChannel.
Channel Status The status of the group.
