PA-4000 series and agg/dual links

L0 Member


I'm looking to upgrade my company firewall (PA-2050) to one of the PA-4000 series to be the internet gateway for all our US sites.  Anyone here is using PA-4000 with aggregate links with Cisco switches?  I'm thinking to have aggregate links for both Trust and Untrust and also dual path to our two Coreswitchs for redudancy as well.  I know the 4000 series support aggregate links but not sure if I will be able to do this on both of my switches.  So in short, Core1 and Core 2 switch will have Etherchannel links to the PA and all four ports on the PA will belong to Trust zone.

You'd be able to connect the aggregate ports asigned to the Trust Zone on the PAN to two differnent Etherchannel connections on the Ciscos.  Just be aware that the PAN won't support LACP traffic in instances where it is participating in link aggregation and we assume static setup of the port configuration.  The PAN will pass through LACP traffic in VWire mode, where it is not doing link aggregation.

Here is a link to an article on link aggregation which you may or may not have seen.
