Switching

Hi,

I have two EX3300 setup in Virtual Chassis. The switch sits between my ISP and redundant firewalls (pfsense),

All three ports (ISP, Primary Firewall and backup firewall) are configured as Layer 2 Uplink in the EX-3300.

ge0/0/0 port rule: layer 2 uplink  --> ISP

ge0/0/1 port rule: layer 2 uplink --> Firewall A

ge1/0/0 port rule: layer 2 uplink --> Firewall B

Currently, I have one connection from my ISP and I'd like to have some redundancy there. Our ISP is in the same data-center as us, and I can get a second cable from them. My ISP wants me to setup link aggregation.

How can I setup link aggregation when the port is configured as Layer 2 Uplink? Can someone please provide some advise here?

Thanks.

You need to configure the currently used interface as child link of an aggregate and also add another physical interface as the secnd child link of the aggregate. After that, all VLAN/port mode configuration is done on the aggregate.

Thanks you. Based on your response, then "Layer 2 Uplike" profile is same as making a port mode trunk, correct?

Yes, just move the configuration that you now have on the single physical link to the aggregate interface.

OK. Thanks.
