[j-nsp] Angry EX (STP?)

[cb at packetrail.net]

Hello,

We have three EX4500's in the following configuration:



EX4500#1---------EX4500#2--------EX4500#3

                    |

                    |

                 MX80 (router)



We are observing xe-0/0/16 on the EX#2 facing the EX#1 site having its
port blocked and unblocked over and over(see log below).   I'd prefer to
disable STP, rSTP, lldp and lldp-med, but if I do we see blocking as
well...  We are only using point to poing VLANs and there is no physical
possibility of a L2 loop.  I have deleted the STP statement, and suspect
rSTP has taken over.



Any ideas as to how to stabilize (or eliminate) our STP, rSTP, lldp,
lldp-med environment?



Thanks in Advance!



CB.





Log Snip  (yes, it is still Aug 25th in our world. Will fix.  ;-)
