Tip You must list all the ports that belong to the EtherChannel in this one command. To
add or delete individual ports from the bundle, reissue this command with an updated list
of all the desired ports.
b. Set the PAgP mode:
interface) channel-group number mode {on | auto [non-silent] | desirable
[non-silent]}
The channel is referenced by one of its ports by selecting the interface and the
group number. You can configure PAgP in one of these modes: on
(EtherChannel is used, but no PAgP packets are sent), off (EtherChannel is dis-
abled), desirable (switch is actively willing to form an EtherChannel; PAgP pack-
ets are sent), or auto (switch is passively willing to form an EtherChannel; no
PAgP packets are sent; the default).
When in auto or desirable mode, PAgP packets are required before an
EtherChannel can be negotiated and brought up. However, there might be times
when one end of the EtherChannel (a server or network analyzer) doesn't gener-
ate PAgP packets or is "silent." You can use the silent keyword (the default) to
enable a port to become an EtherChannel with a silent partner after a 15-second
delay. Use the non-silent keyword to require PAgP negotiation before bringing
the EtherChannel active.
c. (Optional) Choose a load-balancing algorithm:
