Hi,
we have an issue with our backups / backup performance / loadbalancing.
We have a few DMZ servers, where the only possible backup is via the frontend, so communication via Firewall.
The Firewall is an ASA, connected via 6x1G Copper Portchannel to our core switch (6807-XL).
The problem here is, since the cores use src-dst-ip as loadbalancing algorithm on the Port-Channel, the backup is running on only one of these 6 links, since source & destination IP are always the same.
This causes:
A) slow backups
B) Alarms from our performance monitoring, since bandwidth consumption on the 1G-Port > 95%.
I wanted to change the LB method to something different, in order to have a better distribution on all of the links, but when I try to do this on the core-side Port-Channel, I get the error message "This command is not supported for this interface".
Is there any way how I could change this Port-Channel LB method on a 6800?
Thanks in advance!

Hi,
thanks - seems plausible.
If I change that on global level - is there any impact/disruption of traffic?
Should I change it on all connected devices (connected Nexus, Access-Switches, etc.), or is it OK to have different settings on the two sides?

Many thanks, I'll try this tonight
