I am working to replace our cisco core switch stack (3750s) with a EX4600/4300 mixed virtual chassis. All closets are currently cisco 3750;s which trunk back to the core.
Currently the cisco trunks(etherchannel) are configured with LACP and on all Cisco switches (core and closets) the following load balancing option is set in the config:
port-channel load-balance src-dst-ip
In my test environement where I am working on the juniper EX virtual chassis, I have created serveral LAGs configured with LACP active connecting to 3750 switches and all seems to be working well.
However, with the port-channel load-balance src-dst-ip set in the cisco configuration, the ICMP times are more than double compared to simply removing this from the Cisco config.
THis brings me to my questions:
Is it possible on the Juniper EX switches to set the load balance settings to match the cisco src-dst-ip configuration? Or should this simply be disabled on the Cisco switches? What is the proper config?
