Slow/unstable performance on 5300xl
We have 4 5300xl's in a VLAN setup with routing enabled connected with gigabit fibers.
When e.g. pinging a server on the main switch from a node on one of the other switches AND in another subnet/VLAN the response times are not at all satisfactoriuos (probably spelled that wrong :0) ).
I know that the routing process will slow the traffic down a little bit, and the response times are usually 4-6ms which should be OK.
However, every tenth time (or so) there are times at over 200ms to almost 1sec. I've even experienced drop-outs with a single "destination unreachable" every now and then.
Now my question to you is: Why could this be happening? Within the same VLAN across more switches there are no problems, so it must be something with the routing process. FYI there's no ACL's configured on the implied VLANs and routing is only enabled on the main switch.
Hope one of you have a good suggestion to what this could be caused by.
Thanks in advance,
Rasmus

Re: Slow/unstable performance on 5300xl
We are testing some HP 9300 routers and Catalyst 3550 switches as well, no problems with them in the same topology.

20x 2650 as edge switches with 9 vlans over
all switches, running the two 5308 with ospf and xrrp. routing between all vlans is working fine netio test is over 11000kb/s

Re: Slow/unstable performance on 5300xl
It reads: "For the Switch 5300XL Series devices, enter an explicit default route (0.0.0.0 0.0.0.0 or 0.0.0.0/0) as a static route in the IP route table."
Maybe if you type this into your config you'll get rid of the problem.

Re: Slow/unstable performance on 5300xl
So, of course we have entered the default route as well.

Re: Slow/unstable performance on 5300xl
you can have STATIC ROUTES in your routing table without this necessarily meaning you have a DEFAULT ROUTE. It is very good you have defined a DEFAULT ROUTE, as per HP's recommendations and, yes, I know the DEFAULT ROUTE is one of your STATIC ROUTES.
But I am not sure these clarifications solved Rasmus's problem.
