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. ;-) Aug 25 12:09:37 ALBQ_EX4500 init: lldpd-service (PID 20934) started Aug 25 12:09:39 ALBQ_EX4500 lldp[20934]: TASK_TASK_BEGIN: Commencing virtual chassis control daemon, version 10.3R1.9, built builder by 2010-08-13 12:56:38 UTC Aug 25 12:09:39 ALBQ_EX4500 /kernel: Aug 25 12:09:39 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:10:05 ALBQ_EX4500 last message repeated 7 times Aug 25 12:12:06 ALBQ_EX4500 last message repeated 348 times Aug 25 12:13:14 ALBQ_EX4500 last message repeated 288 times Aug 25 12:13:19 ALBQ_EX4500 mgd[19934]: UI_DBASE_LOGOUT_EVENT: User 'xxxxxx' exiting configuration mode Aug 25 12:13:36 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:14:04 ALBQ_EX4500 last message repeated 20 times Aug 25 12:16:06 ALBQ_EX4500 last message repeated 61 times Aug 25 12:26:05 ALBQ_EX4500 last message repeated 1679 times Aug 25 12:35:42 ALBQ_EX4500 last message repeated 1419 times Aug 25 12:40:15 ALBQ_EX4500 last message repeated 356 times Aug 25 12:40:15 ALBQ_EX4500 mgd[19934]: UI_DBASE_LOGIN_EVENT: User 'xxxxxx' entering configuration mode Aug 25 12:40:15 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:40:21 ALBQ_EX4500 last message repeated 10 times Aug 25 12:41:06 ALBQ_EX4500 last message repeated 2 times Aug 25 12:41:07 ALBQ_EX4500 mgd[19934]: UI_CHILD_EXITED: Child exited: PID 20977, status 1, command '/sbin/ifinfo' Aug 25 12:41:11 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:41:11 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:41:12 ALBQ_EX4500 mgd[19934]: UI_CHILD_EXITED: Child exited: PID 20979, status 1, command '/sbin/ifinfo' Aug 25 12:41:15 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:41:35 ALBQ_EX4500 last message repeated 16 times Aug 25 12:41:36 ALBQ_EX4500 mgd[19934]: UI_DBASE_LOGOUT_EVENT: User 'xxxxxx' exiting configuration mode Aug 25 12:41:37 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:42:06 ALBQ_EX4500 last message repeated 60 times Aug 25 12:42:28 ALBQ_EX4500 last message repeated 85 times Aug 25 12:42:29 ALBQ_EX4500 mgd[19934]: UI_DBASE_LOGIN_EVENT: User 'xxxxxx' entering configuration mode Aug 25 12:42:29 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:42:35 ALBQ_EX4500 last message repeated 32 times Aug 25 12:43:07 ALBQ_EX4500 last message repeated 135 times Aug 25 12:43:07 ALBQ_EX4500 mgd[19934]: UI_DBASE_LOGOUT_EVENT: User 'xxxxxx' exiting configuration mode Aug 25 12:43:07 ALBQ_EX4500 mib2d[861]: SNMP_TRAP_LINK_DOWN: ifIndex 536, ifAdminStatus up(1), ifOperStatus down(2), ifName xe-0/0/16 Aug 25 12:43:35 ALBQ_EX4500 last message repeated 104 times _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
