Good morning all. I have a problem with my MICE connection and I'm wondering if anyone can give me some direction. On September 9th, my predecessor disabled our port facing MICE due to BGP flapping (his description). Since there was chatter on this board about a fiber cut that day, he thought it was related to that. Unfortunately, when I re-enabled the port, I saw similar behavior. BGP seems to flap about every three minutes, and my log indicates that link is actually dropping on that port. Even though light levels never seem to drop below -4.4db, I had Cologix check the cross connect, clean the ends of the fiber, and re-seat the sfp. None of that helped. On Wednesday I replaced the SFP, but when I enabled the port, I still saw the same behavior. Last night I disabled all of my BGP peers and brought the port back online for further layer2 testing, but I can't ping any of my peers and I'm not seeing any arp entries on this port. Anyone have any ideas what could be going on or what I should check next? I've included my port config below for reference. The log entries associated with this problem are: Oct 22 08:17:33:I:SYSTEM: port 2/4 link fault status is cleared(physical link goes down 24) Oct 22 08:17:33:I:SYSTEM: port 2/4 is down( local fault) Oct 22 08:17:33:I:System: Interface ethernet 2/4, state down - local fault Oct 22 08:17:09:I:System: Interface ethernet 2/4, state up Oct 22 08:16:45:W: Latched low RX Power warning, port 2/4 Oct 22 08:16:45:A: Latched low RX Power alarm, port 2/4 interface ethernet 2/4 port-name BGP peering with MICE Arista 5/19 XC23175 load-interval 30 no fdp enable no cdp enable route-only ip address xxx.xxx.xxx.xxx/24 no spanning-tree sflow forwarding !
