Who is the RE and who is the Backup RE? Although SW 1 is connected directly to SW2 and SW3 it goes to one of them through all the other switches, I think it is SW3 which SW1 goes all the round.

I know 4u seems like a VERY small amount of latency, but it's an issue for our system. I have a set of five ex-4248t switches, connected via virtual chassis such that no two switches are more then two hops apart, as show below. 1 to 2 2 to 4 4 to 5 1 to 3 3 to 5 I have host A connected to switch 1, and host B connected to switch 2, my latency is 27u, but when I move host B to switch 3, the latency goes up to 31u, these numbers are 100% repeatable, so it's not just some simple variation in a one time test. This seems odd, since switch 2 and 3 are both a directly connected to switch 1. What is even more odd, is the farther away from switch 1 you get numerically, the higher the latency gets (1 to 4 is 34u, and 1 to 5 is 37u) This is a huge issue for us, as we cannot connect hosts to anything other then switch 1 and 2 currently due to the increase in latency. Any input from the group would be appreciate. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp No virus found in this incoming message.
