Hi,
I'm a bit confused with the output of traceroute and ping on our Core switch. There is a printer on our network that is not always reachable. Sometimes we can ping it and sometimes we can't. It seems that we can always ping it from a device on the same VLAN but, devices on other VLANs can only sometimes ping it. Here is some output:
NCR6509#ping 170.117.aa.aaa
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 170.117.aa.aaa, timeout is 2 seconds:

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/4 ms

Do you need more info?
Any ideas? Thanks, Pat.
