Switching

Hi

I'm trying to setup MC-LAG port between two core QFX10008 switches to an access EX4550 switch.

ICCP is up, other mc-lags to other access switches are up (QFX5100),

i'm attaching configuration in a hope that someone will take a look and find what am I missing here

Thanks in advanced you all!

MC-LAG is down

Member Link : ae45
Current State Machine's State: mcae active state
Configuration Check Status : Passed
Local Status : active
Local State : down
Peer Status : active
Peer State : down
Logical Interface : ae45.0
Topology Type : bridge
Local State : up
Peer State : up
Peer Ip/MCP/State : <peer_ip> ae1.0 up

other MC-LAGs on same redundancy group are up

Member Link : ae20
Current State Machine's State: mcae active state
Configuration Check Status : Passed
Local Status : active
Local State : up
Peer Status : active
Peer State : up
Logical Interface : ae20.0
Topology Type : bridge
Local State : up
Peer State : up
Peer Ip/MCP/State : <peer_ip> ae1.0 up

What does set chassis aggregated-devices ethernet device-count look like?

QFX-SW1- device-count 10;

QFX-SW2-device-count 10;

EX4550- device-count 1;

Right, and how many ae's are on SW1 and SW2? Just wondering if you've gone over.

HI

Thanks for your reply

I've got 6 on each 10K (SW1+SW2)

Hi,

Do you see the physical interfaces up?

Can also check:

show lacp interfaces aeX

Hi

Yes, Sure

Thanks again for taking the time trying to assist

In the config the ae at the SW45 end is ae45, are these different interfaces?

Switch 1
ae1405 up down MC-LAG TRUNK to SW45.XXX (BBL)
 
Switch 2
ae1405 up down MC-LAG TRUNK to SW45.XXX (BBL)

Oh, sorry

I'd forget mentioning I had recreated ae45, and it's now ae1405, all the configurations are the same on the QFX10K regarding the ae configs.

On switch45 - it's still ae0

Thanks

Hi Smicker,

Just wanted to let you know that this issue was resolved today.

1. The issue concerned spanning tree configuration on the 4550 and the 10K 

at this point the physical status went up

and the show interfaces mc-ae indicated local iccp state as down.

2. in addition, I had to change the High numbered mc-ae (45,1405,2405) to a value lower than what is configured on the chassis device-count.

at this point the iccp synced with the peer device.

I'd like to thank you for your efforts assisting me with this.

Thanks!

David
