The following is an example of a misconfigured Cisco configuration related to Crossbeam configuration referenced below.
Port channel configuration
interface Port-channel12
description WAN-MLT
switchport
switchport access vlan 195
switchport trunk encapsulation dot1q
switchport trunk allowed vlan 191,195 <-----accidentally tagging vlan 191
switchport mode trunk
no ip address
spanning-tree portfast
Within the following line of the XOS configuration, using the "wan" base circuit to establish LACP will automatically assume the "logical-all" statement, which is not visible within the CLI configuration.
...
mode multi-link circuit wan
...
As a reminder, the "logical-all" statement accepts all valid vlans ranging from 1-4094.
