3226 software routing

[lfvgomes]

Hello

My department has been using Superstack 3226 as an edge router. Some days, during some hours, it stops routing and responding to ping. When we can access its page, we see the message below:



Current network configuration requires use of software routing, resulting in degraded performance.



The release notes (sw version is 1.02) says this can happen due to:

a) more then 14 routed subnets - we have 11;

b) unable to contact next-hop routers - it can (at least when it works;

c) no default gateway configured - it is configured;

d) during a short time learning new routes - the problem last for more than 30 minutes, then I have to reset the switch.



Can anyone help me understand what's happening?

Thanks
