The member ports of portchannel are still in selected state and can still forward traffic when the portchannel is configured to down #2066
Description
Description
I successfully configured PortChannel0001 between the two devices using two physical links. The related configuration is as follows:
"PORT": {
"Ethernet1": {
"alias": "Ethernet2/1",
"lanes": "9",
"index": "1",
"speed": "10000"
},
"Ethernet2": {
"alias": "Ethernet3/1",
"lanes": "10",
"index": "2",
"speed": "10000"
},
"Ethernet3": {
"alias": "Ethernet4/1",
"lanes": "11",
"index": "3",
"speed": "10000"
}
},
"PORTCHANNEL": {
"PortChannel0001": {
"members": [
"Ethernet2",
"Ethernet3"
]
}
},
"VLAN_MEMBER": {
"Vlan17|PortChannel0001": {
"tagging_mode": "untagged"
},
"Vlan17|Ethernet1": {
"tagging_mode": "untagged"
}
},
"VLAN": {
"Vlan17": {
"vlanid": "17"
}
},
Portchannel0001 is configured as down and it is admin down, but the member ports are still in the selected state, and can still forward traffic. The following is the operation process(Use # as a comment prompt).
