Configuring LACP Port Channel Min-Links: Examples
This example shows how to configure LACP port-channel min-links:
switch > enable
switch# configure terminal
switch(config)# interface port-channel 25
switch(config-if)# port-channel min-links 3
switch# show etherchannel 25 summary
switch# end
When the minimum links requirement is not met in standalone switches, the port-channel is flagged and
assigned SM/SN or RM/RN state.
switch# show etherchannel 25 summary
Flags: D - down P - bundled in port-channel
I - stand-alone s - suspended
H - Hot-standby (LACP only)
R - Layer3 S - Layer2
U - in use N- not in use, no aggregration
f - failed to allocate aggregator
M - not in use, no aggregation due to minimum links not met
m- not in use, port not aggregated due to minimum links not met
u - unsuitable for bundling
w - waiting to be aggregated
d - default port
Number of channel-groups in use: 125
Number of aggregators: 125
