Routing issue

We've been lighting up the network in a new bldg that's slated to open
in the next month or so and I'm having some weird routing issues.

I can get to devices past the router from both directions at this
location, but the switch over there cannot ping past the router for
some godforsaken reason. The config looks pretty much identical to all
my other switches (minus different addresses, etc), and my other
switches can ping past the router.

So, I am not able to connect to this switch remotely w/o connecting to
the router first, then getting to the switch. The switch's default
gateway is the router, the router sees all our networks, etc, not sure
what else to try.

Suggestions?

Re: Routing issue

Something is misconfigured. HTH


Routing table?

Maybe the router is not allowing traffic from that IP?

Are you performing any packet filtering on the router?

Other than that... I'd say use a PC connected to the problem switch, run
Wireshark with the port the PC is connected to spanning the port
connected to the router, then from the problem subnet try pinging the
switch which should fail. Look in Wireshark and see if ping ever even
makes it to the switch. If not, it's a router issue. If it does but you
aren't getting the replies it's probably a switch issue though it could
still be a router issue.
