RB750 Ethernet port 1 ping times sanity check

Wed Mar 17, 2010 9:48 am

I have many deployed RB750's at AP sites. Most of them are configured for bridging several ports together to monitor the traffic but I also use them for routing. A client called and said they were having high ping times but my staff checked by pinging the interfaces in question. Everything looked okay. So this evening I ssh' d into the rb750 to look at the Ethernet stats. I noticed that Ethernet 1 in version 3.29 have no stats. Is the is correct?

The 2nd issue is when I ping devices from the terminal that are on ports 2-4 the ping times are <1ms. But when I ping a bullet m5 on port 1 the ping times are 2-5ms. Is this correct correct behavior? I know port 1 is not part of the switch but everything is bridged together.
