Hello,
There is a issue between Juniper and Cisco regarding lacp and portchannel.
| Working configuration on Juniper and Cisco Nexus5K, bellow is a working configuration: | |
| Model: mx960 | System version: 5.2(1)N1(1) |
| JUNOS Base OS boot [12.3R6.6] | |
| interface port-channel55 | |
| set interfaces ae55 description type=core,subtype=isc,int=houir3.ge-1/1/1 | description type=core,subtype=isc,peer=houir3,peerint=ge-1/1/1,peeragg=ae55 |
| set interfaces ae55 traps | switchport mode trunk |
| set interfaces ae55 vlan-tagging | spanning-tree port type edge trunk |
| set interfaces ae55 mtu 2000 | speed 1000 |
| set interfaces ae55 encapsulation flexible-ethernet-services | |
| set interfaces ae55 aggregated-ether-options lacp active | |
| set interfaces ae55 aggregated-ether-options lacp periodic fast | interface Ethernet1/5 |
| description type=core,subtype=isc,peer=houir3,peerint=ge-1/1/1,peeragg=ae55 | |
| set interfaces ge-1/1/1 description type=core,subtype=isc,peer=houobgis2,peerint=Eth1/5,int=ae55 | switchport mode trunk |
| set interfaces ge-1/1/1 gigether-options no-auto-negotiation | speed 1000 |
set interfaces ge-1/1/1 gigether-options 802.3ad ae55
| channel-group 55 mode active |
After replicating the same config on another Juniper MX960 Junos 14.2R6.5 using a different ae -> ae91 connection wont come up:
| ae91 up down type=core,subtype=isc,int=houir5.ge-11/0/5,peerint=po55 |
| port-channel55 is down (No operational members) |
Connection is working without using portchannel and LACP.
Can someone help with that ?
