I am still sorting out the details. But it was related to the card swap scheduled for today. The card was in up and running without an issue for several minutes, however when I programmed/moved the first link to it, all of the other cards in the core switch started rebooting themselves. I am opening a ticket with Arista since we seem to be stable at the moment. -----Original Message----- From: MICE Discuss <MICE-DISCUSS@LISTS.IPHOUSE.NET> On Behalf Of Chris Wopat Sent: Wednesday, February 14, 2024 4:56 PM To: MICE-DISCUSS@LISTS.IPHOUSE.NET Subject: [MICE-DISCUSS] MICE interface flap WiscNet's remote switch flapped twice within the last half hour: Feb 14 16:34:16.657 2024 s-minneapolis-hub mib2d[8448]: %DAEMON-4-SNMP_TRAP_LINK_DOWN: ifIndex 540, ifAdminStatus up(1), ifOperStatus down(2), ifName et-0/0/23 Feb 14 16:39:29.456 2024 s-minneapolis-hub mib2d[8448]: %DAEMON-4-SNMP_TRAP_LINK_DOWN: ifIndex 540, ifAdminStatus up(1), ifOperStatus down(2), ifName et-0/0/23 Aggregate traffic definitely shows a hit: http://micelg.usinternet.com/export/graph_2625.html Curious if others experienced flaps or could reveal logs from the core Arista? -- Chris Wopat Network Engineer, WiscNet wopat@wiscnet.net 608-210-3965
