Intermittent "request time out"

[longegg]

Hi Guys,

I have a problem when I try to ping computers in another vlan. I'm in the default vlan and the other vlan is 7. Nothing appears to be wrong with the router/firewall and if I go to one of those computer in vlan 7 i can ping all other computers in the same vlan no problem. It's only when I try to ping from a computer in my vlan.

Any help would be great!

I can think of two obvious things:
1/ Duplex mis-match on your switch-router link: check the port statistics on your uplink ports and see if there are errors on them

2/ badly-configured multiple-link uplink - if you have an etherchannel or LACP trunk between switch-router, disable any redundant links and try again with just a simple single link uplink

Thanks. I'll take a look at it again and let you know what I find.
