Pings on the LAN

I'm pinging different switches from different machines on the network on different VLANS.

Souldn't these responses be of concern?

Pat,

time=3ms

Usually the time increases when you have load on the interface.  So, I would say the timing fluctuation is ok.

TTL=62

This TTL seems to be very low. The TTL starts from 255 and decrements one going over each hop.  How far (how many hops) these devices are sitting from your laptop or desktop?

HTH

It is not correct to say that TTL always starts at 255. The TTL is set by the OS of the device that sends the packet. And some do start at 255 (which is the maximum value that it can be). But some other OS set the TTL differently. And I have seen fairly often TTL that starts at 64.

Richard,

When you say, some OS set it to start at 64, what devices are they?

Are you referring to window operating systems?

Thanks,

Reza
