I'm having a problem whereby I'm not seeing SG-300 switches in my traceroute output.
I can perform a trace off my LAN and over a WAN with each hop enumerated correctly - however the first two hops are always showing as timed out.This is true when I ping other hosts on my network. These are both SG-300 switchesin layer 3 mode.
Tracing route to XXXXXXXX
over a maximum of 30 hops:
1 * * * Request timed out.
2 * * * Request timed out.
3 1 ms 1 ms 1 ms X.X.0.7
...etc.
...etc.
A traceroute to hop 2 above correctly shows hop 2, but shows the same problem with hop 1
Tracing route to X.X.0.1
over a maximum of 30 hops:
1 * * * Request timed out.
2 1 ms 5 ms 5 ms X.X.0.1
Trace complete.
A bit of digging around leads me to believe this is a problem with ICMP type 11 messages not being sent from the switch. Am I missing something fundamental here? Any input or pointers appreciated.
