I just installed a 6509 Cat Switch to replace a very old Foundry Network. Prior to the install I could ping everything. But now I cannot ping part of the 10.5 network. This is a /16 subnet. I can ping 10.5.200.x routers etc, but I cannot ping any hosts in 10.5.1.x. These hosts cannot see the default gateway of 10.5.200.1. Currently these hosts are in vlan1 (becuase thats what Foundry had them in and they still need to connect to some server irons). When I run a trace route from the cisco switch I get this:
Type escape sequence to abort.
Tracing the route to 10.5.1.9
1 10.10.1.14 0 msec 0 msec 0 msec
2 10.10.1.34 4 msec 0 msec 4 msec
188.8.131.52 !H *
10.10.1.34 is a watch guard fw that connects to the router 10.5.200.1. I checked the fw and don't see any issues there.
Any help is greatly appreicated.
