One side is "active".

channel-group 1 mode passive

The other side is "passive". 

 

Both sides need to the same.

LACP Modes

Config looks Good.

Can you please shut all those interfaces and bring up again?

Table 31-2 shows the user-configurable EtherChannel LACP modes for the channel-group interface configuration command on an NNI.

 

Table 31-2 EtherChannel LACP Modes 

Mode
Description

active

Places a port into an active negotiating state in which the port starts negotiations with other ports by sending LACP packets.

passive

Places a port into a passive negotiating state in which the port responds to LACP packets that it receives, but does not start LACP packet negotiation. This setting minimizes the transmission of LACP packets.

 

 

Both the active and passive LACP modes enable ports to negotiate with partner ports to an EtherChannel based on criteria such as port speed and, for Layer 2 EtherChannels, trunking state and VLAN numbers.

Ports can form an EtherChannel when they are in different LACP modes as long as the modes are compatible. For example:

A port in the active mode can form an EtherChannel with another port that is in the active or passive mode.

A port in the passive mode cannot form an EtherChannel with another port that is also in the passive mode because neither port starts LACP negotiation.
