Yes, this is still on track for today. I have just arrived at the data center. I do plan on blocking port 179 for a minimum of 5 minutes prior to taking the switch down. I will send out another email at 2 p.m. right before I begin the maintenance Jeremy Lumby Minnesota VoIP 9217 17th Ave S Suite 216 Bloomington MN 55425 Main 612-355-7740 Direct 612-392-6814 EFax 952-873-7425 jlumby@mnvoip.com -------- Original message -------- From: James Urwiller <james.urwiller@TURNKEY-TELECOM.COM> Date: 1/18/19 1:01 PM (GMT-06:00) To: MICE-DISCUSS@LISTS.IPHOUSE.NET Subject: Re: [MICE-DISCUSS] Subscription Mail: Re: [MICE-DISCUSS] [MICE-ANNOUNCE] MICE 100Gig Card Replacement Maintenance Window _____ thinking it would be like a fiber cut where we have no valid routes while timers count down.

After yesterday's meeting discussion about the 100G card replacement on the MICE core switch, I now have a tracking number for a new 100G card from Arista. Based on needing 7 days of major maintenance notice, and a request to complete before MLK day it looks like Friday 1/18/2019 at 2PM CST will be the best time to complete the maintenance. The new card requires a switch OS upgrade. Based on an Arista recommendation, I will be upgrading to 4.20.11M prior to the card replacement. This will cause a total traffic disruption on the MICE core switch. Prior to the maintenance I will be blocking BGP on all ports of the core switch to allow traffic to gracefully reroute. If you choose to shutdown BGP on your own prior to the maintenance, please leave your interface enabled so that link can be verified after the maintenance completes.
