asymmetric routing

[ney25]

Hi NetPros,

Good Day :) , well i have a question about the asymmetric routing traffic problem , recently my network performance feel very slow takes almost 1 hour only can upload 1 file. this wasn't happened before (Cisco and HP have confirmed this is caused by Asymmetric Routing , once you adjust the mac-address agingtime to 14,440 or higher then problem can be solved). my question is why the Asymmetric Routing problem came out suddenly ? is that any documents or link can i refer to ? basically management wants to know the root cause of this. so i wish those NetPros can share with me about your experiences .

thanks a lot and your reply will be really higly appreciate.

regards,

Jack

Sounds like a unicast flooding issue. See http://www.cisco.com/en/US/products/hw/switches/ps700/products_tech_note09186a00801d0808.shtml
